# Betty Framework Skills
## ⚙️ **Integration Note: Claude Code Plugin System**
**Betty skills are Claude Code plugins.** You do not invoke skills via standalone CLI commands (`betty` or direct Python scripts). Instead:
- **Claude Code serves as the execution environment** for all skill execution
- Each skill is registered through its `skill.yaml` manifest
- Skills become automatically discoverable and executable through Claude Code's natural language interface
- All routing, validation, and execution is handled by Claude Code via MCP (Model Context Protocol)
**No separate installation step is needed** beyond plugin registration in your Claude Code environment.
---
This directory contains skill manifests and implementations for the Betty Framework.
## What are Skills?
Skills are **atomic, composable building blocks** that execute specific operations. Unlike agents (which orchestrate multiple skills with reasoning) or workflows (which follow fixed sequential steps), skills are:
- **Atomic** — Each skill does one thing well
- **Composable** — Skills can be combined into complex workflows
- **Auditable** — Every execution is logged with inputs, outputs, and provenance
- **Type-safe** — Inputs and outputs are validated against schemas
## Directory Structure
Each skill has its own directory containing:
```
skills/
├── <skill-name>/
│ ├── skill.yaml # Skill manifest (required)
│ ├── SKILL.md # Documentation (auto-generated)
│ ├── <skill_name>.py # Implementation handler (required)
│ ├── requirements.txt # Python dependencies (optional)
│ └── tests/ # Skill tests (optional)
│ └── test_skill.py
```
## Creating a Skill
### Using meta.skill (Recommended)
**Via Claude Code:**
```
"Use meta.skill to create a custom.processor skill that processes custom data formats,
accepts raw-data and config as inputs, and outputs processed-data"
```
**Direct execution (development/testing):**
```bash
cat > /tmp/my_skill.md <<'EOF'
# Name: custom.processor
# Purpose: Process custom data formats
# Inputs: raw-data, config
# Outputs: processed-data
# Dependencies: python-processing-tools
EOF
python agents/meta.skill/meta_skill.py /tmp/my_skill.md
```
### Manual Creation
1. Create skill directory:
```bash
mkdir -p skills/custom.processor
```
2. Create skill manifest (`skills/custom.processor/skill.yaml`):
```yaml
name: custom.processor
version: 0.1.0
description: "Process custom data formats"
inputs:
- name: raw-data
type: file
description: "Input data file"
required: true
- name: config
type: object
description: "Processing configuration"
required: false
outputs:
- name: processed-data
type: file
description: "Processed output file"
dependencies:
- python-processing-tools
status: draft
```
3. Implement the handler (`skills/custom.processor/custom_processor.py`):
```python
#!/usr/bin/env python3
"""Custom data processor skill implementation."""
import sys
from pathlib import Path
def main():
if len(sys.argv) < 2:
print("Usage: custom_processor.py <raw-data> [config]")
sys.exit(1)
raw_data = Path(sys.argv[1])
config = sys.argv[2] if len(sys.argv) > 2 else None
# Your processing logic here
print(f"Processing {raw_data} with config {config}")
if __name__ == "__main__":
main()
```
4. Validate and register:
**Via Claude Code:**
```
"Use skill.define to validate skills/custom.processor/skill.yaml,
then use registry.update to register it"
```
**Direct execution (development/testing):**
```bash
python skills/skill.define/skill_define.py skills/custom.processor/skill.yaml
python skills/registry.update/registry_update.py skills/custom.processor/skill.yaml
```
## Skill Manifest Schema
### Required Fields
| Field | Type | Description |
|-------|------|-------------|
| `name` | string | Unique identifier (e.g., `api.validate`) |
| `version` | string | Semantic version (e.g., `0.1.0`) |
| `description` | string | Human-readable purpose statement |
| `inputs` | array[object] | Input parameters and their types |
| `outputs` | array[object] | Output artifacts and their types |
### Optional Fields
| Field | Type | Description |
|-------|------|-------------|
| `status` | enum | `draft`, `active`, `deprecated`, `archived` |
| `dependencies` | array[string] | External tools or libraries required |
| `tags` | array[string] | Categorization tags |
| `examples` | array[object] | Usage examples |
| `error_handling` | object | Error handling strategies |
## Skill Categories
### Foundation Skills
- **skill.create** — Generate new skill scaffolding
- **skill.define** — Validate skill manifests
- **registry.update** — Update component registries
- **workflow.compose** — Chain skills into workflows
### API Development Skills
- **api.define** — Create API specifications
- **api.validate** — Validate specs against guidelines
- **api.generate-models** — Generate type-safe models
- **api.compatibility** — Detect breaking changes
### Governance Skills
- **audit.log** — Record audit events
- **policy.enforce** — Validate against policies
- **telemetry.capture** — Capture usage metrics
- **registry.query** — Query component registry
### Infrastructure Skills
- **agent.define** — Validate agent manifests
- **agent.run** — Execute agents
- **plugin.build** — Bundle plugins
- **plugin.sync** — Sync plugin manifests
### Documentation Skills
- **docs.sync.readme** — Regenerate README files
- **generate.docs** — Auto-generate documentation
- **docs.validate.skill_docs** — Validate documentation completeness
## Using Skills
### Via Claude Code (Recommended)
Simply ask Claude to execute the skill by name:
```
"Use api.validate to check specs/user-service.openapi.yaml against Zalando guidelines"
"Use artifact.create to create a threat-model artifact named payment-system-threats"
"Use registry.query to find all skills in the api category"
```
### Direct Execution (Development/Testing)
For development and testing, you can invoke skill handlers directly:
```bash
python skills/api.validate/api_validate.py specs/user-service.openapi.yaml
python skills/artifact.create/artifact_create.py \
threat-model \
"Payment processing system" \
./artifacts/threat-model.yaml
python skills/registry.query/registry_query.py --category api
```
## Validation
All skill manifests are automatically validated for:
- Required fields presence
- Name format (`^[a-z][a-z0-9._-]*$`)
- Version format (semantic versioning)
- Input/output schema correctness
- Dependency declarations
## Registry
Validated skills are registered in `/registry/skills.json`:
```json
{
"registry_version": "1.0.0",
"generated_at": "2025-10-26T00:00:00Z",
"skills": [
{
"name": "api.validate",
"version": "0.1.0",
"description": "Validate API specs against guidelines",
"inputs": [...],
"outputs": [...],
"status": "active"
}
]
}
```
## Composing Skills into Workflows
Skills can be chained together using the `workflow.compose` skill:
**Via Claude Code:**
```
"Use workflow.compose to create a workflow that:
1. Uses api.define to create a spec
2. Uses api.validate to check it
3. Uses api.generate-models to create TypeScript models"
```
**Workflow YAML definition:**
```yaml
name: api-development-workflow
version: 0.1.0
steps:
- skill: api.define
inputs:
service_name: "user-service"
outputs:
spec_path: "${OUTPUT_DIR}/user-service.openapi.yaml"
- skill: api.validate
inputs:
spec_path: "${steps[0].outputs.spec_path}"
outputs:
validation_report: "${OUTPUT_DIR}/validation-report.json"
- skill: api.generate-models
inputs:
spec_path: "${steps[0].outputs.spec_path}"
language: "typescript"
outputs:
models_dir: "${OUTPUT_DIR}/models/"
```
## Testing Skills
Skills should include comprehensive tests:
```python
# tests/test_custom_processor.py
import pytest
from skills.custom_processor import custom_processor
def test_processor_with_valid_input():
result = custom_processor.process("test-data.json", {"format": "json"})
assert result.success
assert result.output_path.exists()
def test_processor_with_invalid_input():
with pytest.raises(ValueError):
custom_processor.process("nonexistent.json")
```
Run tests:
```bash
pytest tests/test_custom_processor.py
```

# agent.define Skill
Validates and registers agent manifests for the Betty Framework.
## Purpose
The `agent.define` skill is the Layer 2 (Reasoning Layer) equivalent of `skill.define`. It validates agent manifests (`agent.yaml`) for schema compliance, verifies skill references, and updates the central Agent Registry.
## Capabilities
- Validate agent manifest structure and required fields
- Verify agent name and version formats
- Validate reasoning mode enum values
- Check that all referenced skills exist in skill registry
- Ensure capabilities and skills lists are non-empty
- Validate status lifecycle values
- Register valid agents in `/registry/agents.json`
- Update existing agent entries with new versions
## Usage
### Command Line
```bash
python skills/agent.define/agent_define.py <path_to_agent.yaml>
```
### Arguments
| Argument | Type | Required | Description |
|----------|------|----------|-------------|
| `manifest_path` | string | Yes | Path to the agent.yaml file to validate |
### Exit Codes
- `0`: Validation succeeded and agent was registered
- `1`: Validation failed or registration error
## Validation Rules
### Required Fields
All agent manifests must include:
| Field | Type | Validation |
|-------|------|------------|
| `name` | string | Must match `^[a-z][a-z0-9._-]*$` |
| `version` | string | Must follow semantic versioning |
| `description` | string | Non-empty string (1-200 chars recommended) |
| `capabilities` | array[string] | Must contain at least one item |
| `skills_available` | array[string] | Must contain at least one item, all skills must exist in registry |
| `reasoning_mode` | enum | Must be `iterative` or `oneshot` |
### Optional Fields
| Field | Type | Default | Validation |
|-------|------|---------|------------|
| `status` | enum | `draft` | Must be `draft`, `active`, `deprecated`, or `archived` |
| `context_requirements` | object | `{}` | Any valid object |
| `workflow_pattern` | string | `null` | Any string |
| `example_task` | string | `null` | Any string |
| `error_handling` | object | `{}` | Any valid object |
| `output` | object | `{}` | Any valid object |
| `tags` | array[string] | `[]` | Array of strings |
| `dependencies` | array[string] | `[]` | Array of strings |
### Name Format
Agent names must:
- Start with a lowercase letter
- Contain only lowercase letters, numbers, dots, hyphens, underscores
- Follow pattern: `<domain>.<action>`
**Valid**: `api.designer`, `compliance.checker`, `data-migrator`
**Invalid**: `ApiDesigner`, `1agent`, `agent_name`
### Version Format
Versions must follow semantic versioning: `MAJOR.MINOR.PATCH[-prerelease]`
**Valid**: `0.1.0`, `1.0.0`, `2.3.1-beta`, `1.0.0-rc.1`
**Invalid**: `1.0`, `v1.0.0`, `1.0.0.0`
### Reasoning Mode
Must be one of:
- `iterative`: Agent can retry with feedback and refine based on errors
- `oneshot`: Agent executes once without retry
### Skills Validation
All skills in `skills_available` must exist in the skill registry (`/registry/skills.json`).
## Response Format
### Success Response
```json
{
"ok": true,
"status": "success",
"errors": [],
"path": "agents/api.designer/agent.yaml",
"details": {
"valid": true,
"errors": [],
"path": "agents/api.designer/agent.yaml",
"manifest": {
"name": "api.designer",
"version": "0.1.0",
"description": "Design RESTful APIs...",
"capabilities": [...],
"skills_available": [...],
"reasoning_mode": "iterative"
},
"status": "registered",
"registry_updated": true
}
}
```
### Failure Response
```json
{
"ok": false,
"status": "failed",
"errors": [
"Missing required fields: capabilities, skills_available",
"Invalid reasoning_mode: 'hybrid'. Must be one of: iterative, oneshot"
],
"path": "agents/bad.agent/agent.yaml",
"details": {
"valid": false,
"errors": [
"Missing required fields: capabilities, skills_available",
"Invalid reasoning_mode: 'hybrid'. Must be one of: iterative, oneshot"
],
"path": "agents/bad.agent/agent.yaml"
}
}
```
## Examples
### Example 1: Validate Iterative Agent
**Agent Manifest** (`agents/api.designer/agent.yaml`):
```yaml
name: api.designer
version: 0.1.0
description: "Design RESTful APIs following enterprise guidelines"
capabilities:
- Design RESTful APIs from requirements
- Apply Zalando guidelines automatically
- Generate OpenAPI 3.1 specs
- Iteratively refine based on validation feedback
skills_available:
- api.define
- api.validate
- api.generate-models
reasoning_mode: iterative
status: draft
tags:
- api
- design
- openapi
```
**Command**:
```bash
python skills/agent.define/agent_define.py agents/api.designer/agent.yaml
```
**Output**:
```json
{
"ok": true,
"status": "success",
"errors": [],
"path": "agents/api.designer/agent.yaml",
"details": {
"valid": true,
"status": "registered",
"registry_updated": true
}
}
```
### Example 2: Validation Errors
**Agent Manifest** (`agents/bad.agent/agent.yaml`):
```yaml
name: BadAgent # Invalid: must be lowercase
version: 1.0 # Invalid: must be semver
description: "Test agent"
capabilities: [] # Invalid: must have at least one
skills_available:
- nonexistent.skill # Invalid: skill doesn't exist
reasoning_mode: hybrid # Invalid: must be iterative or oneshot
```
**Command**:
```bash
python skills/agent.define/agent_define.py agents/bad.agent/agent.yaml
```
**Output**:
```json
{
"ok": false,
"status": "failed",
"errors": [
"Invalid name: Invalid agent name: 'BadAgent'. Must start with lowercase letter...",
"Invalid version: Invalid version: '1.0'. Must follow semantic versioning...",
"Invalid reasoning_mode: Invalid reasoning_mode: 'hybrid'. Must be one of: iterative, oneshot",
"capabilities must contain at least one item",
"Skills not found in registry: nonexistent.skill"
],
"path": "agents/bad.agent/agent.yaml"
}
```
### Example 3: Oneshot Agent
**Agent Manifest** (`agents/api.analyzer/agent.yaml`):
```yaml
name: api.analyzer
version: 0.1.0
description: "Analyze API specifications for compatibility"
capabilities:
- Detect breaking changes between API versions
- Generate compatibility reports
- Suggest migration paths
skills_available:
- api.compatibility
reasoning_mode: oneshot
output:
success:
- Compatibility report
- Breaking changes list
failure:
- Error analysis
status: active
tags:
- api
- analysis
- compatibility
```
**Command**:
```bash
python skills/agent.define/agent_define.py agents/api.analyzer/agent.yaml
```
**Result**: Agent validated and registered successfully.
## Integration
### With Registry
The skill automatically updates `/registry/agents.json`:
```json
{
"registry_version": "1.0.0",
"generated_at": "2025-10-23T10:30:00Z",
"agents": [

### With Other Skills
- **Depends on**: `skill.define` (for skill registry validation)
- **Used by**: Future `command.define` skill (to register commands that invoke agents)
- **Complements**: `workflow.compose` (agents orchestrate skills; workflows execute fixed sequences)
## Common Errors
### Missing Skills in Registry
**Error**:
```
Skills not found in registry: api.nonexistent, data.missing
```
**Solution**: Ensure all skills in `skills_available` are registered in `/registry/skills.json`. Check skill names for typos.
### Invalid Reasoning Mode
**Error**:
```
Invalid reasoning_mode: 'hybrid'. Must be one of: iterative, oneshot
```
**Solution**: Use `iterative` for agents that retry with feedback, or `oneshot` for deterministic execution.
### Empty Capabilities
**Error**:
```
capabilities must contain at least one item
```
**Solution**: Add at least one capability string describing what the agent can do.
### Invalid Name Format
**Error**:
```
Invalid agent name: 'API-Designer'. Must start with lowercase letter...
```
**Solution**: Use lowercase names following pattern `<domain>.<action>` (e.g., `api.designer`).
## Development
### Testing
Create test agent manifests in `/agents/test/`:
```bash
# Create test directory
mkdir -p agents/test.agent
# Create minimal test manifest
cat > agents/test.agent/agent.yaml << EOF
name: test.agent
version: 0.1.0
description: "Test agent"
capabilities:
- Test capability
skills_available:
- skill.define
reasoning_mode: oneshot
status: draft
EOF
# Validate
python skills/agent.define/agent_define.py agents/test.agent/agent.yaml
```
### Registry Location
- Skill registry: `/registry/skills.json` (read for validation)
- Agent registry: `/registry/agents.json` (updated by this skill)

# agent.run
**Version:** 0.1.0
**Status:** Active
**Tags:** agents, execution, claude-api, orchestration, layer2
## Overview
The `agent.run` skill executes registered Betty agents by orchestrating the complete agent lifecycle: loading manifests, generating Claude-friendly prompts, invoking the Claude API (or simulating), executing planned skills, and logging all results.
This skill is the primary execution engine for Betty agents, enabling them to operate in both **iterative** and **oneshot** reasoning modes. It handles the translation between agent manifests and Claude API calls, manages skill invocation, and provides comprehensive logging for auditability.
## Features
- ✅ Load agent manifests from path or agent name
- ✅ Generate Claude-optimized system prompts with capabilities and workflow patterns
- ✅ Optional Claude API integration (with mock fallback for development)
- ✅ Support for both iterative and oneshot reasoning modes
- ✅ Skill selection and execution orchestration
- ✅ Comprehensive execution logging to `agent_logs/<agent>_<timestamp>.json`
- ✅ Structured JSON output for programmatic integration
- ✅ Error handling with detailed diagnostics
- ✅ Validation of agent manifests and available skills
## Usage
### Command Line
```bash
# Execute agent by name
python skills/agent.run/agent_run.py api.designer
# Execute with task context
python skills/agent.run/agent_run.py api.designer "Design a REST API for user management"
# Execute from manifest path
python skills/agent.run/agent_run.py agents/api.designer/agent.yaml "Create authentication API"
# Execute without saving logs
python skills/agent.run/agent_run.py api.designer "Design API" --no-save-log
```
### As a Skill (Programmatic)
```python
import sys
import os
sys.path.insert(0, os.path.abspath("./"))
from skills.agent.run.agent_run import run_agent
# Execute agent
result = run_agent(
agent_path="api.designer",
task_context="Design a REST API for user management with authentication",
save_log=True
)
if result["ok"]:
print(f"Agent executed successfully!")
print(f"Skills invoked: {result['details']['summary']['skills_executed']}")
print(f"Log saved to: {result['details']['log_path']}")
else:
print(f"Execution failed: {result['errors']}")
```
### Via Claude Code Plugin
```bash
# Using the Betty plugin command
/agent/run api.designer "Design authentication API"
# With full path
/agent/run agents/api.designer/agent.yaml "Create user management endpoints"
```
## Input Parameters
| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `agent_path` | string | Yes | - | Path to agent.yaml or agent name (e.g., `api.designer`) |
| `task_context` | string | No | None | Task or query to provide to the agent |
| `save_log` | boolean | No | true | Whether to save execution log to disk |

}
}
```
## Reasoning Modes
### Oneshot Mode
In **oneshot** mode, the agent analyzes the complete task and plans all skill invocations upfront in a single pass. The execution follows the predetermined plan without dynamic adjustment.
**Best for:**
- Well-defined tasks with predictable workflows
- Tasks where all steps can be determined in advance
- Performance-critical scenarios requiring minimal API calls
**Example Agent:**
```yaml
name: api.generator
reasoning_mode: oneshot
workflow_pattern: |
1. Define API structure
2. Validate specification
3. Generate models
```
### Iterative Mode
In **iterative** mode, the agent analyzes results after each skill invocation and dynamically determines the next steps. It can retry failed operations, adjust its approach based on feedback, or invoke additional skills as needed.
**Best for:**
- Complex tasks requiring adaptive decision-making
- Tasks with validation/refinement loops
- Scenarios where results influence subsequent steps
**Example Agent:**
```yaml
name: api.designer
reasoning_mode: iterative
workflow_pattern: |
1. Analyze requirements
2. Draft OpenAPI spec
3. Validate (if fails, refine and retry)
4. Generate models
```
## Examples
### Example 1: Execute API Designer
```bash
python skills/agent.run/agent_run.py api.designer \
"Create a REST API for managing blog posts with CRUD operations"
```
**Output:**
```

# Load and inspect agent before running
manifest = load_agent_manifest("api.designer")
print(f"Agent capabilities: {manifest['capabilities']}")
# Execute with custom context
result = run_agent(
agent_path="api.designer",
task_context="Design GraphQL API for e-commerce",
save_log=True
)
if result["ok"]:
# Access execution details
claude_response = result["details"]["claude_response"]
execution_results = result["details"]["execution_results"]
print(f"Claude planned {len(claude_response['skills_to_invoke'])} skills")
print(f"Executed {len(execution_results)} skills")
# Check individual skill results
for exec_result in execution_results:
print(f" - {exec_result['skill']}: {exec_result['status']}")
```
## Agent Manifest Requirements
For `agent.run` to successfully execute an agent, the agent manifest must include:
### Required Fields
```yaml
name: agent.name # Must match pattern ^[a-z][a-z0-9._-]*$
version: 0.1.0 # Semantic version
description: "..." # Clear description
capabilities: # List of capabilities
- "Capability 1"
- "Capability 2"
skills_available: # List of Betty skills
- skill.name.1
- skill.name.2
reasoning_mode: iterative # 'iterative' or 'oneshot'
```
### Recommended Fields
```yaml
workflow_pattern: | # Recommended workflow steps
1. Step 1
2. Step 2
3. Step 3
context_requirements: # Optional context hints
guidelines: string
domain: string
error_handling: # Error handling config
max_retries: 3
timeout_seconds: 300
status: active # Agent status (draft/active/deprecated)
tags: # Categorization tags
- tag1
- tag2
```
## Claude API Integration
The skill supports both real Claude API calls and mock simulation:
### Real API Mode (Production)
Set the `ANTHROPIC_API_KEY` environment variable:
```bash
export ANTHROPIC_API_KEY="sk-ant-..."
python skills/agent.run/agent_run.py api.designer "Design API"
```
The skill will:
1. Detect the API key
2. Use the Anthropic Python SDK
3. Call Claude 3.5 Sonnet with the constructed prompt
4. Parse the structured JSON response
5. Execute the skills based on Claude's plan
### Mock Mode (Development)
Without an API key, the skill generates intelligent mock responses:
```bash
python skills/agent.run/agent_run.py api.designer "Design API"
```
The skill will:
1. Detect no API key
2. Generate plausible skill selections based on agent type
3. Simulate Claude's reasoning
4. Execute skills with simulated outputs
## Execution Logging
All agent executions are logged to `agent_logs/<agent>_<timestamp>.json` with:
- **Timestamp**: ISO 8601 UTC timestamp
- **Agent Info**: Name, version, description, mode, status
- **Task Context**: User-provided task or query
- **Prompt**: Complete Claude system prompt
- **Skills Available**: Registered skills with metadata
- **Missing Skills**: Skills referenced but not found
- **Claude Response**: Full API response or mock
- **Execution Results**: Output from each skill invocation
- **Summary**: Counts, success status, timing
### Log File Structure
```json
{
"timestamp": "2025-10-23T14:30:00Z",
"agent": { /* agent metadata */ },
"task_context": "Design API for...",
"prompt": "You are api.designer...",
"skills_available": [ /* skill info */ ],
"missing_skills": [],
"claude_response": { /* Claude's plan */ },
"execution_results": [ /* skill outputs */ ],
"summary": {
"skills_planned": 3,
"skills_executed": 3,
"success": true
}
}
```
### Accessing Logs
```bash
# View latest log for an agent
cat agent_logs/api.designer_latest.json | jq '.'
# View specific execution
cat agent_logs/api.designer_20251023_143000.json | jq '.summary'
# List all logs for an agent
ls -lt agent_logs/api.designer_*.json
```
## Error Handling
### Common Errors
**Agent Not Found**
```json
{
"ok": false,
"status": "failed",
"errors": ["Agent not found: my.agent"],
"details": {
"error": {
"type": "BettyError",
"message": "Agent not found: my.agent",
"details": {
"agent_path": "my.agent",
"expected_path": "/home/user/betty/agents/my.agent/agent.yaml",
"suggestion": "Use 'betty agent list' to see available agents"
}
}
}
}
```
**Invalid Agent Manifest**
```json
{
"ok": false,
"errors": ["Agent manifest missing required fields: reasoning_mode, capabilities"],
"details": {
"error": {
"type": "BettyError",
"details": {
"missing_fields": ["reasoning_mode", "capabilities"]
}
}
}
}
```
**Skill Not Found**
- The execution continues but logs missing skills in `missing_skills` array
- Warning logged for each missing skill
- Agent may not function as intended if critical skills are missing
### Debugging Tips
1. **Check agent manifest**: Validate with `betty agent validate <agent_path>`
2. **Verify skills**: Ensure all `skills_available` are registered
3. **Review logs**: Check `agent_logs/<agent>_latest.json` for details
4. **Enable debug logging**: Set `BETTY_LOG_LEVEL=DEBUG`
5. **Test with mock mode**: Remove API key to test workflow logic
## Best Practices
### 1. Agent Design
- Define clear, specific capabilities in agent manifests
- Choose appropriate reasoning mode for the task complexity
- Provide detailed workflow patterns to guide Claude
- Include context requirements for optimal prompts
### 2. Task Context
- Provide specific, actionable task descriptions
- Include relevant domain context when needed
- Reference specific requirements or constraints
- Use examples to clarify ambiguous requests
### 3. Logging
- Keep logs enabled for production (default: `save_log=true`)
- Review logs regularly for debugging and auditing
- Archive old logs periodically to manage disk space
- Use log summaries to track agent performance
### 4. Error Recovery
- In iterative mode, agents can retry failed skills
- Review error details in logs for root cause analysis
- Validate agent manifests before deployment
- Test with mock mode before using real API calls
### 5. Performance
- Use oneshot mode for predictable, fast execution
- Cache agent manifests when running repeatedly
- Monitor Claude API usage and costs
- Consider skill execution time when designing workflows
## Integration with Betty Framework
### Skill Dependencies
`agent.run` depends on:
- **agent.define**: For creating agent manifests
- **Skill registry**: For validating available skills
- **Betty configuration**: For paths and settings
### Plugin Integration
The skill is registered in `plugin.yaml` as:
```yaml
- name: agent/run
description: Execute a registered Betty agent
handler:
runtime: python
script: skills/agent.run/agent_run.py
parameters:
- name: agent_path
type: string
required: true
```
This enables Claude Code to invoke agents directly:
```
User: "Run the API designer agent to create a user management API"
Claude: [Invokes /agent/run api.designer "create user management API"]
```
## Related Skills
- **agent.define** - Create and register new agent manifests
- **agent.validate** - Validate agent manifests before execution
- **run.agent** - Legacy simulation tool (read-only, no execution)
- **skill.define** - Register skills that agents can invoke
- **hook.simulate** - Test hooks before registration
## Changelog

- Initial implementation
- Support for iterative and oneshot reasoning modes
- Claude API integration with mock fallback

# api.define
## Overview
**api.define** scaffolds OpenAPI and AsyncAPI specifications from enterprise-compliant templates, generating production-ready API contracts with best practices built-in.
## Purpose
Quickly create API specifications that follow enterprise guidelines:
- Generate Zalando-compliant OpenAPI 3.1 specs
- Generate AsyncAPI 3.0 specs for event-driven APIs
- Include proper error handling (RFC 7807 Problem JSON)
- Use correct naming conventions (snake_case)
- Include required metadata and security schemes
## Usage
### Basic Usage
```bash
python skills/api.define/api_define.py <service_name> [spec_type] [options]
```
### Parameters
| Parameter | Required | Description | Default |
|-----------|----------|-------------|---------|
| `service_name` | Yes | Service/API name | - |
| `spec_type` | No | openapi or asyncapi | `openapi` |
| `--template` | No | Template name | `zalando` |
| `--output-dir` | No | Output directory | `specs` |
| `--version` | No | API version | `1.0.0` |
## Examples
### Example 1: Create Zalando-Compliant OpenAPI Spec
```bash
python skills/api.define/api_define.py user-service openapi --template=zalando
```
**Output**: `specs/user-service.openapi.yaml`
Generated spec includes:
- ✅ Required Zalando metadata (`x-api-id`, `x-audience`)
- ✅ CRUD operations for users resource
- ✅ RFC 7807 Problem JSON for errors
- ✅ snake_case property names
- ✅ X-Flow-ID headers for tracing
- ✅ Proper HTTP status codes
- ✅ JWT authentication scheme
### Example 2: Create AsyncAPI Spec
```bash
python skills/api.define/api_define.py user-service asyncapi
```
**Output**: `specs/user-service.asyncapi.yaml`
Generated spec includes:
- ✅ Lifecycle events (created, updated, deleted)
- ✅ Kafka channel definitions
- ✅ Event payload schemas
- ✅ Publish/subscribe operations
### Example 3: Custom Output Directory
```bash
python skills/api.define/api_define.py order-api openapi \
--output-dir=api-specs \
--version=2.0.0
```
## Generated OpenAPI Structure
For a service named `user-service`, the generated OpenAPI spec includes:
**Paths**:
- `GET /users` - List users with pagination
- `POST /users` - Create new user
- `GET /users/{user_id}` - Get user by ID
- `PUT /users/{user_id}` - Update user
- `DELETE /users/{user_id}` - Delete user
**Schemas**:
- `User` - Main resource schema
- `UserCreate` - Creation payload schema
- `UserUpdate` - Update payload schema
- `Pagination` - Pagination metadata
- `Problem` - RFC 7807 error schema
**Responses**:
- `200` - Success (with X-Flow-ID header)
- `201` - Created (with Location and X-Flow-ID headers)
- `204` - No Content (for deletes)
- `400` - Bad Request (application/problem+json)
- `404` - Not Found (application/problem+json)
- `409` - Conflict (application/problem+json)
- `500` - Internal Error (application/problem+json)
**Security**:
- Bearer token authentication (JWT)
**Required Metadata**:
- `x-api-id` - Unique UUID
- `x-audience` - Target audience (company-internal)
- `contact` - Team contact information
## Resource Name Extraction
The skill automatically extracts resource names from service names:
| Service Name | Resource | Plural |
|--------------|----------|--------|
| `user-service` | user | users |
| `order-api` | order | orders |
| `payment-gateway` | payment | payments |
## Naming Conventions
The skill automatically applies proper naming:
| Context | Convention | Example |
|---------|------------|---------|
| Paths | kebab-case | `/user-profiles` |
| Properties | snake_case | `user_id` |
| Schemas | TitleCase | `UserProfile` |
| Operations | camelCase | `getUserById` |
## Integration with api.validate
The generated specs are designed to pass `api.validate` with zero errors:
```bash
# Generate spec
python skills/api.define/api_define.py user-service
# Validate (should pass)
python skills/api.validate/api_validate.py specs/user-service.openapi.yaml zalando
```
## Use in Workflows
```yaml
# workflows/api_first_development.yaml
steps:
- skill: api.define
args:
- "user-service"
- "openapi"
- "--template=zalando"
output: spec_path
- skill: api.validate
args:
- "{spec_path}"
- "zalando"
required: true
```
## Customization
After generation, customize the spec:
1. **Add properties** to schemas:
```yaml
User:
properties:
user_id: ...
email: # Add this
type: string
format: email
```
2. **Add operations**:
```yaml
/users/search: # Add new endpoint
post:
summary: Search users
```
3. **Modify metadata**:
```yaml
info:
contact:
name: Your Team Name # Update this
email: team@company.com
```
## Output
### Success Response
```json
{
"status": "success",
"data": {
"spec_path": "specs/user-service.openapi.yaml",
"spec_content": {...},
"api_id": "d0184f38-b98d-11e7-9c56-68f728c1ba70",
"template_used": "zalando",
"service_name": "user-service"
}
}
```
## Dependencies
- **PyYAML**: Required for YAML handling
```bash
pip install pyyaml
```
## Templates
| Template | Spec Type | Description |
|----------|-----------|-------------|
| `zalando` | OpenAPI | Zalando-compliant with all required fields |
| `basic` | AsyncAPI | Basic event-driven API structure |

# api.generate-models
## Overview
**api.generate-models** generates type-safe models from OpenAPI and AsyncAPI specifications, enabling shared models between frontend and backend using code generation.
## Purpose
Transform API specifications into type-safe code:
- Generate TypeScript interfaces from OpenAPI schemas
- Generate Python dataclasses/Pydantic models
- Generate Java classes, Go structs, C# classes
- Single source of truth: the API specification
- Automatic synchronization when specs change
## Usage
### Basic Usage
```bash
python skills/api.generate-models/modelina_generate.py <spec_path> <language> [options]
```
### Parameters
| Parameter | Required | Description | Default |
|-----------|----------|-------------|---------|
| `spec_path` | Yes | Path to API spec file | - |
| `language` | Yes | Target language | - |
| `--output-dir` | No | Output directory | `src/models` |
| `--package-name` | No | Package/module name | - |
### Supported Languages
| Language | Extension | Status |
|----------|-----------|--------|
| `typescript` | `.ts` | ✅ Supported |
| `python` | `.py` | ✅ Supported |
| `java` | `.java` | 🚧 Planned |
| `go` | `.go` | 🚧 Planned |
| `csharp` | `.cs` | 🚧 Planned |
| `rust` | `.rs` | 🚧 Planned |
## Examples
### Example 1: Generate TypeScript Models
```bash
python skills/api.generate-models/modelina_generate.py \
specs/user-service.openapi.yaml \
typescript \
--output-dir=src/models/user-service
```
**Generated files**:
```
src/models/user-service/
├── User.ts
├── UserCreate.ts
├── UserUpdate.ts
├── Pagination.ts
└── Problem.ts
```
**Example TypeScript output**:
```typescript
// src/models/user-service/User.ts
export interface User {
/** Unique identifier */
user_id: string;
/** Creation timestamp */
created_at: string;
/** Last update timestamp */
updated_at?: string;
}
// src/models/user-service/Pagination.ts
export interface Pagination {
/** Number of items per page */
limit: number;
/** Number of items skipped */
offset: number;
/** Total number of items available */
total: number;
}
```
### Example 2: Generate Python Models
```bash
python skills/api.generate-models/modelina_generate.py \
specs/user-service.openapi.yaml \
python \
--output-dir=src/models/user_service
```
**Generated files**:
```
src/models/user_service/
└── models.py
```
**Example Python output**:
```python
# src/models/user_service/models.py
from pydantic import BaseModel, Field
from typing import Optional
from datetime import datetime
from uuid import UUID
class User(BaseModel):
"""User model"""
user_id: UUID = Field(..., description="Unique identifier")
created_at: datetime = Field(..., description="Creation timestamp")
updated_at: Optional[datetime] = Field(None, description="Last update timestamp")
class Pagination(BaseModel):
"""Pagination metadata"""
limit: int = Field(..., description="Number of items per page")
offset: int = Field(..., description="Number of items skipped")
total: int = Field(..., description="Total number of items available")
```
### Example 3: Generate for Multiple Languages
```bash
# TypeScript for frontend
python skills/api.generate-models/modelina_generate.py \
specs/user-service.openapi.yaml \
typescript \
--output-dir=frontend/src/models
# Python for backend
python skills/api.generate-models/modelina_generate.py \
specs/user-service.openapi.yaml \
python \
--output-dir=backend/app/models
```
## Code Generators Used
The skill uses multiple code generation approaches:
### 1. datamodel-code-generator (Primary)
**Best for**: OpenAPI specs → Python/TypeScript
**Installation**: `pip install datamodel-code-generator`
Generates:
- Python: Pydantic v2 models with type hints
- TypeScript: Type-safe interfaces
- Validates schema during generation
### 2. Simple Built-in Generator (Fallback)
**Best for**: Basic models when external tools not available
**Installation**: None required
Generates:
- Python: dataclasses
- TypeScript: interfaces
- Basic but reliable
### 3. Modelina (Future)
**Best for**: AsyncAPI specs, multiple languages
**Installation**: `npm install -g @asyncapi/modelina`
**Status**: Planned
## Output
### Success Response
```json
{
"status": "success",
"data": {
"models_path": "src/models/user-service",
"files_generated": [
"src/models/user-service/User.ts",
"src/models/user-service/UserCreate.ts",
"src/models/user-service/Pagination.ts",
"src/models/user-service/Problem.ts"
],
"model_count": 4,
"generator_used": "datamodel-code-generator"
}
}
```
## Integration with Workflows
```yaml
# workflows/api_first_development.yaml
steps:
- skill: api.define
args:
- "user-service"
- "openapi"
output: spec_path
- skill: api.validate
args:
- "{spec_path}"
- "zalando"
required: true
- skill: api.generate-models
args:
- "{spec_path}"
- "typescript"
- "--output-dir=frontend/src/models"
- skill: api.generate-models
args:
- "{spec_path}"
- "python"
- "--output-dir=backend/app/models"
```
## Integration with Hooks
Auto-regenerate models when specs change:
```bash
python skills/hook.define/hook_define.py \
on_file_save \
"python betty/skills/api.generate-models/modelina_generate.py {file_path} typescript --output-dir=src/models" \
--pattern="specs/*.openapi.yaml" \
--blocking=false \
--description="Auto-regenerate TypeScript models when OpenAPI specs change"
```
## Benefits
### For Developers
- ✅ **Type safety**: Catch errors at compile time, not runtime
- ✅ **IDE autocomplete**: Full IntelliSense/autocomplete support
- ✅ **No manual typing**: Models generated automatically
- ✅ **Always in sync**: Regenerate when spec changes
### For Teams
- ✅ **Single source of truth**: API spec defines types
- ✅ **Frontend/backend alignment**: Same types everywhere
- ✅ **Reduced errors**: Type mismatches caught early
- ✅ **Faster development**: No manual model creation
### For Organizations
- ✅ **Consistency**: All services use same model generation
- ✅ **Maintainability**: Update spec → regenerate → done
- ✅ **Documentation**: Types are self-documenting
- ✅ **Quality**: Generated code is tested and reliable
## Dependencies
### Required
- **PyYAML**: For YAML parsing (`pip install pyyaml`)
### Optional (Better Output)
- **datamodel-code-generator**: For high-quality Python/TypeScript (`pip install datamodel-code-generator`)
- **Node.js + Modelina**: For AsyncAPI and more languages (`npm install -g @asyncapi/modelina`)
## Examples with Real Specs
Using the user-service spec from Phase 1:
```bash
# Generate TypeScript
python skills/api.generate-models/modelina_generate.py \
specs/user-service.openapi.yaml \
typescript
# Output:
{
"status": "success",
"data": {
"models_path": "src/models",
"files_generated": [
"src/models/User.ts",
"src/models/UserCreate.ts",
"src/models/UserUpdate.ts",
"src/models/Pagination.ts",
"src/models/Problem.ts"
],
"model_count": 5
}
}
```

# api.validate
## Overview
**api.validate** validates OpenAPI and AsyncAPI specifications against enterprise guidelines, with built-in support for Zalando RESTful API Guidelines.
## Purpose
Ensure API specifications meet enterprise standards:
- Validate OpenAPI 3.x specifications
- Validate AsyncAPI 3.x specifications
- Check compliance with Zalando guidelines
- Detect common API design mistakes
- Provide actionable suggestions for fixes
## Usage
### Basic Usage
```bash
python skills/api.validate/api_validate.py <spec_path> [guideline_set] [options]
```
### Parameters
| Parameter | Required | Description | Default |
|-----------|----------|-------------|---------|
| `spec_path` | Yes | Path to API spec file | - |
| `guideline_set` | No | Guidelines to validate against | `zalando` |
| `--strict` | No | Warnings become errors | `false` |
| `--format` | No | Output format (json, human) | `json` |
### Guideline Sets
| Guideline | Status | Description |
|-----------|--------|-------------|
| `zalando` | ✅ Supported | Zalando RESTful API Guidelines |
| `google` | 🚧 Planned | Google API Design Guide |
| `microsoft` | 🚧 Planned | Microsoft REST API Guidelines |
## Examples
### Example 1: Validate OpenAPI Spec
```bash
python skills/api.validate/api_validate.py specs/user-service.openapi.yaml zalando
```
**Output** (JSON format):
```json
{
"status": "success",
"data": {
"valid": false,
"errors": [
{
"rule_id": "MUST_001",
"message": "Missing required field 'info.x-api-id'",
"severity": "error",
"path": "info.x-api-id",
"suggestion": "Add a UUID to uniquely identify this API"
}
],
"warnings": [
{
"rule_id": "SHOULD_001",
"message": "Missing 'info.contact'",
"severity": "warning",
"path": "info.contact"
}
],
"spec_path": "specs/user-service.openapi.yaml",
"spec_type": "openapi",
"guideline_set": "zalando"
}
}
```
### Example 2: Human-Readable Output
```bash
python skills/api.validate/api_validate.py \
specs/user-service.openapi.yaml \
zalando \
--format=human
```
**Output**:
```
============================================================
API Validation Report
============================================================
Spec: specs/user-service.openapi.yaml
Type: OPENAPI
Guidelines: zalando
============================================================
❌ ERRORS (1):
[MUST_001] Missing required field 'info.x-api-id'
Path: info.x-api-id
💡 Add a UUID to uniquely identify this API
⚠️ WARNINGS (1):
[SHOULD_001] Missing 'info.contact'
Path: info.contact
💡 Add contact information
============================================================
❌ Validation FAILED
============================================================
```
### Example 3: Strict Mode
```bash
python skills/api.validate/api_validate.py \
specs/user-service.openapi.yaml \
zalando \
--strict
```
In strict mode, warnings are treated as errors. Use for CI/CD pipelines where you want zero tolerance for issues.
### Example 4: Validate AsyncAPI Spec
```bash
python skills/api.validate/api_validate.py specs/user-events.asyncapi.yaml
```
## Validation Rules
### Zalando Guidelines (OpenAPI)
#### MUST Rules (Errors)
| Rule | Description | Example Fix |
|------|-------------|-------------|
| **MUST_001** | Required `x-api-id` metadata | `x-api-id: 'd0184f38-b98d-11e7-9c56-68f728c1ba70'` |
| **MUST_002** | Required `x-audience` metadata | `x-audience: 'company-internal'` |
| **MUST_003** | Path naming conventions | Use lowercase kebab-case or snake_case |
| **MUST_004** | Property naming (snake_case) | `userId` → `user_id` |
| **MUST_005** | HTTP method usage | GET should not have requestBody |
#### SHOULD Rules (Warnings)
| Rule | Description | Example Fix |
|------|-------------|-------------|
| **SHOULD_001** | Contact information | Add `info.contact` with team details |
| **SHOULD_002** | POST returns 201 | Add 201 response to POST operations |
| **SHOULD_003** | Document 400 errors | Add 400 Bad Request response |
| **SHOULD_004** | Document 500 errors | Add 500 Internal Error response |
| **SHOULD_005** | 201 includes Location header | Add Location header to 201 responses |
| **SHOULD_006** | Problem schema for errors | Define RFC 7807 Problem schema |
| **SHOULD_007** | Error responses use application/problem+json | Use correct content type |
| **SHOULD_008** | X-Flow-ID header | Add request tracing header |
| **SHOULD_009** | Security schemes defined | Add authentication schemes |
### AsyncAPI Guidelines
| Rule | Description |
|------|-------------|
| **ASYNCAPI_001** | Required `info` field |
| **ASYNCAPI_002** | Required `channels` field |
| **ASYNCAPI_003** | Version check (recommend 3.x) |
## Integration with Hooks
### Automatic Validation on File Edit
```bash
# Create hook using hook.define
python skills/hook.define/hook_define.py \
on_file_edit \
"python betty/skills/api.validate/api_validate.py {file_path} zalando" \
--pattern="*.openapi.yaml" \
--blocking=true \
--timeout=10000 \
--description="Validate OpenAPI specs on edit"
```
**Result**: Every time you edit a `*.openapi.yaml` file, it's automatically validated. If validation fails, the edit is blocked.
### Validation on Commit
```bash
python skills/hook.define/hook_define.py \
on_commit \
"python betty/skills/api.validate/api_validate.py {file_path} zalando --strict" \
--pattern="specs/**/*.yaml" \
--blocking=true \
--description="Prevent commits with invalid specs"
```
## Exit Codes
| Code | Meaning |
|------|---------|
| `0` | Validation passed (no errors) |
| `1` | Validation failed (has errors) or execution error |
## Common Validation Errors
### Missing x-api-id
**Error**:
```
Missing required field 'info.x-api-id'
```
**Fix**:
```yaml
info:
title: My API
version: 1.0.0
x-api-id: d0184f38-b98d-11e7-9c56-68f728c1ba70 # Add this
```
### Wrong Property Naming
**Error**:
```
Property 'userId' should use snake_case
```
**Fix**:
```yaml
# Before
properties:
userId:
type: string
# After
properties:
user_id:
type: string
```
### Missing Error Responses
**Error**:
```
GET operation should document 400 (Bad Request) response
```
**Fix**:
```yaml
responses:
'200':
description: Success
'400': # Add this
$ref: '#/components/responses/BadRequest'
'500': # Add this
$ref: '#/components/responses/InternalError'
```
### Wrong Content Type for Errors
**Error**:
```
Error response 400 should use 'application/problem+json'
```
**Fix**:
```yaml
'400':
description: Bad request
content:
application/problem+json: # Not application/json
schema:
$ref: '#/components/schemas/Problem'
```
## Use in Workflows
```yaml
# workflows/api_validation_suite.yaml
steps:
- skill: api.validate
args:
- "specs/user-service.openapi.yaml"
- "zalando"
- "--strict"
required: true
```
## Dependencies
- **PyYAML**: Required for YAML parsing
```bash
pip install pyyaml
```
## Files
### Input
- `*.openapi.yaml` - OpenAPI 3.x specifications
- `*.asyncapi.yaml` - AsyncAPI 3.x specifications
- `*.json` - JSON format specifications
### Output
- JSON validation report (stdout)
- Human-readable report (with `--format=human`)

# artifact.create
## ⚙️ **Integration Note: Claude Code Plugin**
**This skill is a Claude Code plugin.** You do not invoke it via `python skills/artifact.create/artifact_create.py`. Instead:
- **Ask Claude Code** to use the skill: `"Use artifact.create to create a threat-model artifact..."`
- **Claude Code handles** validation, execution, and output interpretation
- **Direct Python execution** is only for development/testing outside Claude Code
---
AI-assisted artifact generation from professional templates.
## Purpose
The `artifact.create` skill enables rapid, high-quality artifact creation by:
1. Loading pre-built templates for 406+ artifact types
2. Populating templates with user-provided business context
3. Applying metadata and document control standards
4. Generating professional, ready-to-review artifacts
## Usage
### Via Claude Code (Recommended)
Simply ask Claude to use the skill:
```
"Use artifact.create to create a business-case artifact for a new customer portal
that improves self-service capabilities and reduces support costs by 40%.
Save it to ./artifacts/customer-portal-business-case.yaml,
authored by Jane Smith, with Internal classification."
"Use artifact.create to create a threat-model artifact for a payment processing API
with PCI-DSS compliance requirements. Save to ./artifacts/payment-api-threat-model.yaml,
authored by Security Team, with Confidential classification."
"Use artifact.create to create a portfolio-roadmap artifact for a digital transformation
initiative covering cloud migration, API platform, and customer experience improvements
over 18 months. Save to ./artifacts/digital-transformation-roadmap.yaml,
authored by Strategy Office."
```
### Direct Execution (Development/Testing)
When working outside Claude Code or for testing:
```bash
python3 skills/artifact.create/artifact_create.py \
<artifact_type> \
<context> \
<output_path> \
[--author "Your Name"] \
[--classification Internal]
```
#### Examples
**Create a Business Case:**
```bash
python3 skills/artifact.create/artifact_create.py \
business-case \
"New customer portal to improve self-service capabilities and reduce support costs by 40%" \
./artifacts/customer-portal-business-case.yaml \
--author "Jane Smith" \
--classification Internal
```
**Create a Threat Model:**
```bash
python3 skills/artifact.create/artifact_create.py \
threat-model \
"Payment processing API with PCI-DSS compliance requirements" \
./artifacts/payment-api-threat-model.yaml \
--author "Security Team" \
--classification Confidential
```
**Create a Portfolio Roadmap:**
```bash
python3 skills/artifact.create/artifact_create.py \
portfolio-roadmap \
"Digital transformation initiative covering cloud migration, API platform, and customer experience improvements over 18 months" \
./artifacts/digital-transformation-roadmap.yaml \
--author "Strategy Office"
```
## How It Works
### 1. Template Selection
- Validates artifact type against KNOWN_ARTIFACT_TYPES registry (406 types)
- Locates appropriate template in `templates/` directory
- Loads template structure (YAML or Markdown format)
### 2. Metadata Population
- Substitutes placeholders: `{{date}}`, `{{your_name}}`, `{{role}}`, etc.
- Applies document control metadata (version, status, classification)
- Sets ownership and approval workflow metadata
### 3. Context Integration
- **YAML artifacts**: Adds context hints within content sections
- **Markdown artifacts**: Inserts context at document beginning
- Preserves TODO markers for manual refinement
### 4. Output Generation
- Creates output directory if needed
- Saves populated artifact to specified path
- Generates detailed report with next steps
## Supported Artifact Types
All 406 registered artifact types are supported, organized in 21 categories:
| Category | Examples |
|----------|----------|
| **Governance** | business-case, portfolio-roadmap, raid-log, decision-log |
| **Architecture** | threat-model, logical-architecture-diagram, data-flow-diagram |
| **Data** | data-model, schema-definition, data-dictionary |
| **Testing** | test-plan, test-results, acceptance-criteria |
| **Security** | security-assessment, vulnerability-report, incident-response-plan |
| **Deployment** | deployment-plan, release-checklist, rollback-plan |
| **Requirements** | requirements-specification, use-case-diagram, user-story |
| **AI/ML** | model-card, training-dataset-description, model-evaluation-report |
See `skills/artifact.define/artifact_define.py` for the complete list.
## Output Formats
### YAML Templates (312 artifacts)
Structured data artifacts for:
- Schemas, models, specifications
- Plans, roadmaps, matrices
- Configurations, manifests, definitions
Example: `business-case.yaml`, `threat-model.yaml`, `data-model.yaml`
### Markdown Templates (94 artifacts)
Documentation artifacts for:
- Reports, guides, manuals
- Policies, procedures, handbooks
- Assessments, analyses, reviews
Example: `incident-report.md`, `runbook.md`, `architecture-guide.md`
## Generated Artifact Structure
Every generated artifact includes:
- ✅ **Document Control**: Version, dates, author, status, classification
- ✅ **Ownership Metadata**: Document owner, approvers, approval workflow
- ✅ **Related Documents**: Links to upstream/downstream dependencies
- ✅ **Structured Content**: Context-aware sections with TODO guidance
- ✅ **Change History**: Version tracking with dates and authors
- ✅ **Reference Links**: Pointers to comprehensive artifact descriptions
## Next Steps After Generation
1. **Review** the generated artifact at the output path
2. **Consult** the comprehensive guidance in `artifact_descriptions/{artifact-type}.md`
3. **Replace** any remaining TODO markers with specific details
4. **Validate** the structure and content against requirements
5. **Update** metadata (status → Review → Approved → Published)
6. **Link** related documents in the metadata section
## Integration with Artifact Framework
### Artifact Metadata
```yaml
artifact_metadata:
produces:
- type: "*" # Dynamically produces any registered artifact type
description: Generated from professional templates
file_pattern: "{{output_path}}"
content_type: application/yaml, text/markdown
consumes:
- type: artifact-type-description
description: References comprehensive artifact descriptions
file_pattern: "artifact_descriptions/*.md"
```
### Workflow Integration
```
User Context → artifact.create → Generated Artifact → artifact.validate → artifact.review
```
Future skills:
- `artifact.validate`: Schema and quality validation
- `artifact.review`: AI-powered content review and recommendations
## Error Handling
### Unknown Artifact Type
```
Error: Unknown artifact type: invalid-type
Available artifact types (showing first 10):
- business-case
- threat-model
- portfolio-roadmap
...
```
### Missing Template
```
Error: No template found for artifact type: custom-type
```
## Performance
- **Template loading**: <50ms
- **Content population**: <200ms
- **Total generation time**: <1 second
- **Output size**: Typically 2-5 KB (YAML), 3-8 KB (Markdown)
## Dependencies
- Python 3.7+
- `artifact.define` skill (for KNOWN_ARTIFACT_TYPES registry)
- Templates in `templates/` directory (406 templates)
- Artifact descriptions in `artifact_descriptions/` (391 files, ~160K lines)
## Status
**Active** - Phase 1 implementation complete
## Tags
artifacts, templates, generation, ai-assisted, tier2
## Version History
- **0.1.0** (2024-10-25): Initial implementation
- Support for all 406 artifact types
- YAML and Markdown template population
- Metadata substitution
- Context integration
- Generation reporting

## Review Dimensions
### 1. Content Completeness (35% weight)
**Analyzes**:
- Word count and content depth
- Placeholder content (TODO, TBD, etc.)
- Field population percentage
- Section completeness
**Scoring Factors**:
- Content too brief (< 100 words): Major issue
- Limited depth (< 300 words): Issue
- Good depth (300+ words): Strength
- Many placeholders (> 10): Major issue
- Few placeholders (< 5): Recommendation
- No placeholders: Strength
- Content fields populated: Percentage-based score
**Example Feedback**:
```
Content Completeness: 33/100
Word Count: 321
Placeholders: 21
✅ Good content depth (321 words)
❌ Many placeholders found (21) - content is incomplete
```
### 2. Professional Quality (25% weight)
**Analyzes**:
- Executive summary presence
- Clear document structure
- Professional tone and language
- Passive voice usage
- Business jargon overuse
**Checks For**:
- ❌ Informal contractions (gonna, wanna)
- ❌ Internet slang (lol, omg)
- ❌ Excessive exclamation marks
- ❌ Multiple question marks
- 🟡 Excessive passive voice (> 50% of sentences)
- 🟡 Jargon overload (> 3 instances)
**Example Feedback**:
```
Professional Quality: 100/100
✅ Includes executive summary/overview
✅ Clear document structure
```
### 3. Best Practices (25% weight)
**Analyzes**:
- Semantic versioning (1.0.0 format)
- Document classification standards
- Approval workflow definition
- Change history maintenance
- Related document links
**Artifact-Specific Checks**:
- **business-case**: ROI analysis, financial justification
- **threat-model**: STRIDE methodology, threat frameworks
- **test-plan**: Test criteria (pass/fail conditions)
**Example Feedback**:
```
Best Practices: 100/100
✅ Uses semantic versioning
✅ Proper document classification set
✅ Approval workflow defined
✅ Maintains change history
✅ Links to related documents
```
### 4. Industry Standards (15% weight)
**Detects References To**:
- TOGAF - Architecture framework
- ISO 27001 - Information security
- NIST - Cybersecurity framework
- PCI-DSS - Payment card security
- GDPR - Data privacy
- SOC 2 - Service organization controls
- HIPAA - Healthcare privacy
- SAFe - Scaled agile framework
- ITIL - IT service management
- COBIT - IT governance
- PMBOK - Project management
- OWASP - Application security
**Recommendations Based On Type**:
- Security artifacts → ISO 27001, NIST, OWASP
- Architecture → TOGAF, Zachman
- Governance → COBIT, PMBOK
- Compliance → SOC 2, GDPR, HIPAA
**Example Feedback**:
```
Industry Standards: 100/100
✅ References: PCI-DSS, ISO 27001
✅ References industry standards: PCI-DSS, ISO 27001
```
## Readiness Score Calculation
```
Readiness Score =
(Completeness × 0.35) +
(Professional Quality × 0.25) +
(Best Practices × 0.25) +
(Industry Standards × 0.15)
```
## Quality Ratings
| Score | Rating | Meaning | Recommendation |
|-------|--------|---------|----------------|
| 90-100 | Excellent | Ready for publication | Submit for approval |
| 75-89 | Good | Ready for approval | Minor polish recommended |
| 60-74 | Fair | Needs refinement | Address key recommendations |
| 40-59 | Needs Improvement | Significant gaps | Major content work needed |
| < 40 | Poor | Major revision required | Substantial rework needed |

======================================================================
```
### Example 2: Comprehensive Review
```bash
$ python3 skills/artifact.review/artifact_review.py \
artifacts/threat-model.yaml \
--review-level comprehensive \
--output threat-model-review.yaml
# Review saved to threat-model-review.yaml
# Use for audit trail and tracking improvements
```
## Integration with artifact.validate
**Recommended workflow**:
```bash
# 1. Validate structure first
python3 skills/artifact.validate/artifact_validate.py my-artifact.yaml --strict
# 2. If valid, review content quality
if [ $? -eq 0 ]; then
python3 skills/artifact.review/artifact_review.py my-artifact.yaml
fi
```
**Combined quality gate**:
```bash
# Both validation and review must pass
python3 skills/artifact.validate/artifact_validate.py my-artifact.yaml --strict && \
python3 skills/artifact.review/artifact_review.py my-artifact.yaml | grep -q "Excellent\|Good"
```
## CI/CD Integration

# artifact.scaffold
Generate new artifact templates automatically from metadata inputs.
## Overview
The `artifact.scaffold` skill creates fully compliant artifact descriptors in one call. It generates valid `.artifact.yaml` files, assigns auto-incremented versions starting at 0.1.0, and registers artifacts in the artifacts registry.
## Features
- **Automatic Generation**: Creates artifact YAML files from metadata inputs
- **Schema Definition**: Supports field definitions with types, descriptions, and required flags
- **Inheritance**: Supports extending from base artifacts
- **Registry Management**: Automatically registers artifacts in `registry/artifacts.json`
- **Validation**: Optional `--validate` flag to validate generated artifacts
- **Version Management**: Auto-assigns version 0.1.0 to new artifacts
## Usage
### Basic Example
```bash
python3 skills/artifact.scaffold/artifact_scaffold.py \
--id "new.artifact" \
--category "report"
```
### With Field Definitions
```bash
python3 skills/artifact.scaffold/artifact_scaffold.py \
--id "new.artifact" \
--category "report" \
--fields '[{"name":"summary","type":"string","description":"Summary field","required":true}]'
```
### With Inheritance and Validation
```bash
python3 skills/artifact.scaffold/artifact_scaffold.py \
--id "new.artifact" \
--category "report" \
--extends "base.artifact" \
--fields '[{"name":"summary","type":"string"}]' \
--validate
```
### Custom Output Path
```bash
python3 skills/artifact.scaffold/artifact_scaffold.py \
--id "new.artifact" \
--category "report" \
--output "custom/path/artifact.yaml"
```
## Input Parameters
| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `--id` | string | Yes | Unique identifier for the artifact (e.g., "new.artifact") |
| `--category` | string | Yes | Category/type of artifact (e.g., "report", "specification") |
| `--extends` | string | No | Base artifact to extend from |
| `--fields` | JSON array | No | Field definitions with name, type, description, and required properties |
| `--output` | string | No | Custom output path for the artifact file |
| `--validate` | flag | No | Validate the artifact after generation |
## Field Definition Format
Fields are provided as a JSON array with the following structure:
```json
[
{
"name": "field_name",
"type": "string|number|boolean|object|array",
"description": "Field description",
"required": true|false
}
]
```
## Output
The skill outputs a JSON response with the following structure:
```json
{
"ok": true,
"status": "success",
"artifact_id": "new.artifact",
"file_path": "/path/to/artifact.yaml",
"version": "0.1.0",
"category": "report",
"registry_path": "/path/to/registry/artifacts.json",
"artifacts_registered": 1,
"validation": {
"valid": true,
"errors": [],
"warnings": []
}
}
```
## Generated Artifact Structure
The skill generates artifact YAML files with the following structure:
```yaml
id: new.artifact
version: 0.1.0
category: report
created_at: '2025-10-26T00:00:00.000000Z'
metadata:
description: new.artifact artifact
tags:
- report
extends: base.artifact # Optional
schema:
type: object
properties:
summary:
type: string
description: Summary field
required:
- summary
```
## Registry Management
Artifacts are automatically registered in `registry/artifacts.json`:
```json
{
"registry_version": "1.0.0",
"generated_at": "2025-10-26T00:00:00.000000Z",
"artifacts": [
{
"id": "new.artifact",
"version": "0.1.0",
"category": "report",
"created_at": "2025-10-26T00:00:00.000000Z",
"description": "new.artifact artifact",
"tags": ["report"],
"extends": "base.artifact",
"schema": { ... }
}
]
}
```
## Dependencies
- `artifact.define`: For artifact type definitions and validation
## Status
**Active** - Ready for production use
## Tags
- artifacts
- scaffolding
- generation
- templates
- metadata

# artifact.validate.types
## Overview
Validates artifact type names against the Betty Framework registry and returns complete metadata for each type. Provides intelligent fuzzy matching and suggestions for invalid types.
**Version**: 0.1.0
**Status**: active
## Purpose
This skill is critical for ensuring skills reference valid artifact types before creation. It validates artifact type names against `registry/artifact_types.json`, retrieves complete metadata (file_pattern, content_type, schema), and suggests alternatives for invalid types using three fuzzy matching strategies:
1. **Singular/Plural Detection** (high confidence) - Detects "data-flow-diagram" vs "data-flow-diagrams"
2. **Generic vs Specific Variants** (medium confidence) - Suggests "logical-data-model" for "data-model"
3. **Levenshtein Distance** (low confidence) - Catches typos like "thret-model" → "threat-model"
This skill is specifically designed to be called by `meta.skill` during Step 2 (Validate Artifact Types) of the skill creation workflow.
## Inputs
| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `artifact_types` | array | Yes | - | List of artifact type names to validate |
| `check_schemas` | boolean | No | `true` | Whether to verify schema files exist on filesystem |
| `suggest_alternatives` | boolean | No | `true` | Whether to suggest similar types for invalid ones |
| `max_suggestions` | number | No | `3` | Maximum number of suggestions per invalid type |
## Outputs
| Output | Type | Description |
|--------|------|-------------|
| `validation_results` | object | Validation results for each artifact type with complete metadata |
| `all_valid` | boolean | Whether all artifact types are valid |
| `invalid_types` | array | List of artifact types that don't exist in registry |
| `suggestions` | object | Suggested alternatives for each invalid type |
| `warnings` | array | List of warnings (e.g., schema file missing) |
## Artifact Metadata
### Produces
- **validation-report** (`*.validation.json`) - Validation results with metadata and suggestions
### Consumes
None - reads directly from registry files
## Usage
### Example 1: Validate Single Artifact Type
```bash
python artifact_validate_types.py \
--artifact_types '["threat-model"]' \
--check_schemas true
```
**Output:**
```json
{
"validation_results": {
"threat-model": {
"valid": true,
"file_pattern": "*.threat-model.yaml",
"content_type": "application/yaml",
"schema": "schemas/artifacts/threat-model-schema.json",
"description": "Threat model (STRIDE, attack trees)..."
}
},
"all_valid": true,
"invalid_types": [],
"suggestions": {},
"warnings": []
}
```
### Example 2: Invalid Type with Suggestions
```bash
python artifact_validate_types.py \
--artifact_types '["data-flow-diagram", "threat-model"]' \
--suggest_alternatives true
```
**Output:**
```json
{
"validation_results": {
"data-flow-diagram": {
"valid": false
},
"threat-model": {
"valid": true,
"file_pattern": "*.threat-model.yaml",
"content_type": "application/yaml",
"schema": "schemas/artifacts/threat-model-schema.json"
}
},
"all_valid": false,
"invalid_types": ["data-flow-diagram"],
"suggestions": {
"data-flow-diagram": [
{
"type": "data-flow-diagrams",
"reason": "Plural form",
"confidence": "high"
},
{
"type": "dataflow-diagram",
"reason": "Similar spelling",
"confidence": "low"
}
]
},
"warnings": [],
"ok": false,
"status": "validation_failed"
}
```
### Example 3: Multiple Invalid Types with Generic → Specific Suggestions
```bash
python artifact_validate_types.py \
--artifact_types '["data-model", "api-spec", "test-result"]' \
--max_suggestions 3
```
**Output:**
```json
{
"all_valid": false,
"invalid_types": ["data-model", "api-spec"],
"suggestions": {
"data-model": [
{
"type": "logical-data-model",
"reason": "Specific variant of model",
"confidence": "medium"
},
{
"type": "physical-data-model",
"reason": "Specific variant of model",
"confidence": "medium"
},
{
"type": "enterprise-data-model",
"reason": "Specific variant of model",
"confidence": "medium"
}
],
"api-spec": [
{
"type": "openapi-spec",
"reason": "Specific variant of spec",
"confidence": "medium"
},
{
"type": "asyncapi-spec",
"reason": "Specific variant of spec",
"confidence": "medium"
}
]
},
"validation_results": {
"test-result": {
"valid": true,
"file_pattern": "*.test-result.json",
"content_type": "application/json"
}
}
}
```
### Example 4: Save Validation Report to File
```bash
python artifact_validate_types.py \
--artifact_types '["threat-model", "architecture-overview"]' \
--output validation-results.validation.json
```
Creates `validation-results.validation.json` with complete validation report.
## Integration with meta.skill
The `meta.skill` agent calls this skill in Step 2 of its workflow:
```yaml
# meta.skill workflow Step 2
2. **Validate Artifact Types**
- Extract artifact types from skill description
- Call artifact.validate.types with all types
- If all_valid == false:
→ Display suggestions to user
→ Ask user to confirm correct types
→ HALT until types are validated
- Store validated metadata for use in skill.yaml generation
```
**Example Integration:**
```python
# meta.skill calls artifact.validate.types
result = subprocess.run([
'python', 'skills/artifact.validate.types/artifact_validate_types.py',
'--artifact_types', json.dumps(["threat-model", "data-flow-diagrams"]),
'--suggest_alternatives', 'true'
], capture_output=True, text=True)
validation = json.loads(result.stdout)
if not validation['all_valid']:
print(f"❌ Invalid artifact types: {validation['invalid_types']}")
for invalid_type, suggestions in validation['suggestions'].items():
print(f"\n Suggestions for '{invalid_type}':")
for s in suggestions:
print(f" - {s['type']} ({s['confidence']} confidence): {s['reason']}")
# HALT skill creation
else:
print("✅ All artifact types validated")
# Continue with skill.yaml generation using validated metadata
```
## Fuzzy Matching Strategies
### Strategy 1: Singular/Plural Detection (High Confidence)
Detects when a user forgets the "s":
| Invalid Type | Suggested Type | Reason |
|-------------|----------------|--------|
| `data-flow-diagram` | `data-flow-diagrams` | Plural form |
| `threat-models` | `threat-model` | Singular form |
### Strategy 2: Generic vs Specific Variants (Medium Confidence)
Suggests specific variants when a generic term is used:
| Invalid Type | Suggested Types |
|-------------|-----------------|
| `data-model` | `logical-data-model`, `physical-data-model`, `enterprise-data-model` |
| `api-spec` | `openapi-spec`, `asyncapi-spec`, `graphql-spec` |
| `architecture-diagram` | `system-architecture-diagram`, `component-architecture-diagram` |
### Strategy 3: Levenshtein Distance (Low Confidence)
Catches typos and misspellings (60%+ similarity):
| Invalid Type | Suggested Type | Similarity |
|-------------|----------------|------------|
| `thret-model` | `threat-model` | ~90% |
| `architecure-overview` | `architecture-overview` | ~85% |
| `api-specfication` | `api-specification` | ~92% |
## Error Handling
### Missing Registry File
```json
{
"ok": false,
"status": "error",
"error": "Artifact registry not found: registry/artifact_types.json"
}
```
**Resolution**: Ensure you're running from the Betty Framework root directory.
### Invalid JSON in artifact_types Parameter
```json
{
"ok": false,
"status": "error",
"error": "Invalid JSON: Expecting ',' delimiter: line 1 column 15 (char 14)"
}
```
**Resolution**: Ensure artifact_types is a valid JSON array with proper quoting.
### Corrupted Registry File
```json
{
"ok": false,
"status": "error",
"error": "Invalid JSON in registry file: ..."
}
```
**Resolution**: Validate and fix `registry/artifact_types.json` syntax.
## Performance
- **Single type validation**: <100ms
- **20 types validation**: <1 second
- **All 409 types validation**: <5 seconds
Memory usage is minimal as registry is loaded once and indexed by name for O(1) lookups.
## Dependencies
- **Python 3.7+**
- **PyYAML** - For reading registry
- **difflib** - For fuzzy matching (Python stdlib)
- **jsonschema** - For validation (optional)
## Testing
Run the test suite:
```bash
cd skills/artifact.validate.types
python test_artifact_validate_types.py
```
**Test Coverage:**
- ✅ Valid artifact type validation
- ✅ Invalid artifact type detection
- ✅ Singular/plural suggestion
- ✅ Generic → specific suggestion
- ✅ Typo detection with Levenshtein distance
- ✅ Max suggestions limit
- ✅ Schema file existence checking
- ✅ Empty input handling
- ✅ Mixed valid/invalid types
## Quality Standards
- **Accuracy**: 100% for exact matches in registry
- **Suggestion Quality**: >80% relevant for common mistakes
- **Performance**: <1s for 20 types, <100ms for single type
- **Schema Verification**: 100% accurate file existence check
- **Error Handling**: Graceful handling of corrupted registry files
## Success Criteria
- ✅ Validates all 409 artifact types correctly
- ✅ Provides accurate suggestions for common mistakes (singular/plural)
- ✅ Returns exact metadata from registry (file_pattern, content_type, schema)
- ✅ Detects missing schema files and warns appropriately
- ✅ Completes validation in <1 second for up to 20 types
- ✅ Fuzzy matching handles typos within 40% character difference
## Troubleshooting
### Skill returns all_valid=false but I think types are correct
1. Check the exact spelling in `registry/artifact_types.json`
2. Look at suggestions - they often reveal plural/singular issues
3. Use `jq` to search registry:
```bash
jq '.artifact_types[] | select(.name | contains("your-search"))' registry/artifact_types.json
```
### Fuzzy matching isn't suggesting the type I expect
1. Check if the type name follows patterns (ending in common suffix like "-model", "-spec")
2. Increase `max_suggestions` to see more options
3. The type might be too dissimilar (< 60% match threshold)
### Schema warnings appearing for valid types
This is normal if schema files haven't been created yet. Schema files are optional for many artifact types. Set `check_schemas=false` to suppress these warnings.

# artifact.validate
Automated artifact validation against structure, schema, and quality criteria.
## Purpose
The `artifact.validate` skill provides comprehensive validation of artifacts to ensure:
- Correct syntax (YAML/Markdown)
- Complete metadata
- Required sections present
- No placeholder content
- Schema compliance (when applicable)
- Quality standards met
## Features
✅ **Syntax Validation**: YAML and Markdown format checking
✅ **Metadata Validation**: Document control completeness
✅ **Section Validation**: Required sections verification
✅ **TODO Detection**: Placeholder and incomplete content identification
✅ **Schema Validation**: JSON schema compliance (when provided)
✅ **Quality Scoring**: 0-100 quality score with breakdown
✅ **Strict Mode**: Enforce all recommendations
✅ **Detailed Reporting**: Actionable validation reports
## Usage
### Basic Validation
```bash
python3 skills/artifact.validate/artifact_validate.py <artifact-path>
```
### With Artifact Type
```bash
python3 skills/artifact.validate/artifact_validate.py \
my-artifact.yaml \
--artifact-type business-case
```
### Strict Mode
```bash
python3 skills/artifact.validate/artifact_validate.py \
my-artifact.yaml \
--strict
```
Strict mode treats warnings as errors. Useful for:
- CI/CD pipeline gates
- Approval workflow requirements
- Production release criteria
### With JSON Schema
```bash
python3 skills/artifact.validate/artifact_validate.py \
my-business-case.yaml \
--schema-path schemas/artifacts/business-case-schema.json
```
### Save Validation Report
```bash
python3 skills/artifact.validate/artifact_validate.py \
my-artifact.yaml \
--output validation-report.yaml
```
## Validation Checks
### 1. Syntax Validation (30% weight)
**YAML Artifacts**:
- Valid YAML syntax
- Proper indentation
- No duplicate keys
- Valid data types
**Markdown Artifacts**:
- At least one heading
- Document control section
- Proper markdown structure
**Score**:
- ✅ Valid: 100 points
- ❌ Invalid: 0 points
### 2. Metadata Completeness (25% weight)
**Required Fields**:
- `version` - Semantic version (e.g., 1.0.0)
- `created` - Creation date (YYYY-MM-DD)
- `author` - Author name or team
- `status` - Draft | Review | Approved | Published
**Recommended Fields**:
- `lastModified` - Last modification date
- `classification` - Public | Internal | Confidential | Restricted
- `documentOwner` - Owning role or person
- `approvers` - Approval workflow
- `relatedDocuments` - Dependencies and references
**Scoring**:
- Missing required field: -25 points each
- Missing recommended field: -10 points each
- TODO placeholder in field: -10 points
### 3. Required Sections (25% weight)
**YAML Artifacts**:
- `metadata` section required
- `content` section expected (unless schema-only artifact)
- Empty content fields detected
**Scoring**:
- Missing required section: -30 points each
- Empty content warning: -15 points each
### 4. TODO Markers (20% weight)
Detects placeholder content:
- `TODO` markers
- `TODO:` comments
- Empty required fields
- Template placeholders
**Scoring**:
- Each TODO marker: -5 points
- Score floor: 0 (cannot go negative)
## Quality Score Interpretation
| Score | Rating | Meaning | Recommendation |
|-------|--------|---------|----------------|
| 90-100 | Excellent | Ready for approval | Minimal polish |
| 70-89 | Good | Minor improvements | Review recommendations |
| 50-69 | Fair | Needs refinement | Address key issues |
| < 50 | Poor | Significant work needed | Major revision required |
## Validation Report Structure
```yaml
success: true
validation_results:
artifact_path: /path/to/artifact.yaml
artifact_type: business-case
file_format: yaml
file_size: 2351
validated_at: 2025-10-25T19:30:00
syntax:
valid: true
error: null
metadata:
complete: false
score: 90
issues: []
warnings:
- "Field 'documentOwner' contains TODO marker"
sections:
valid: true
score: 100
issues: []
warnings: []
todos:
- "Line 10: author: TODO"
- "Line 15: documentOwner: TODO"
# ... more TODOs
quality_score: 84
recommendations:
- "🟡 Complete 1 recommended metadata field(s)"
- "🔴 Replace 13 TODO markers with actual content"
- "🟢 Artifact is good - minor improvements recommended"
is_valid: true
quality_score: 84
```
## Command-Line Options
| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `artifact_path` | string | required | Path to artifact file |
| `--artifact-type` | string | auto-detect | Artifact type override |
| `--strict` | flag | false | Treat warnings as errors |
| `--schema-path` | string | none | Path to JSON schema |
| `--output` | string | none | Save report to file |
## Exit Codes
- `0`: Validation passed (artifact is valid)
- `1`: Validation failed (artifact has critical issues)
In strict mode, warnings also cause exit code `1`.
## Integration Examples
### CI/CD Pipeline (GitHub Actions)
```yaml
name: Validate Artifacts
on: [push, pull_request]
jobs:
validate:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Validate artifacts
run: |
python3 skills/artifact.validate/artifact_validate.py \
artifacts/*.yaml \
--strict
```
### Pre-commit Hook
```bash
#!/bin/bash
# .git/hooks/pre-commit
# Validate all modified YAML artifacts
git diff --cached --name-only | grep '\.yaml$' | while read file; do
python3 skills/artifact.validate/artifact_validate.py "$file" --strict
if [ $? -ne 0 ]; then
echo "❌ Validation failed for $file"
exit 1
fi
done
```
### Makefile Target
```makefile
.PHONY: validate
validate:
@echo "Validating artifacts..."
@find artifacts -name "*.yaml" -exec \
python3 skills/artifact.validate/artifact_validate.py {} \;
```
## Artifact Type Detection
The skill automatically detects artifact type using:
1. **Filename match**: Direct match with registry (e.g., `business-case.yaml`)
2. **Partial match**: Artifact type found in filename (e.g., `portal-business-case.yaml` → `business-case`)
3. **Metadata**: `artifactType` field in YAML metadata
4. **Manual override**: `--artifact-type` parameter
## Error Handling
### File Not Found
```
Error: Artifact file not found: /path/to/artifact.yaml
```
### Unsupported Format
```
Error: Unsupported file format: .txt. Expected yaml, yml, or md
```
### YAML Syntax Error
```
Syntax Validation:
❌ YAML syntax error: while parsing a block mapping
in "<unicode string>", line 3, column 1
expected <block end>, but found '<block mapping start>'
```
## Performance
- **Validation time**: < 100ms per artifact
- **Memory usage**: < 10MB
- **Scalability**: Can validate 1000+ artifacts in batch
## Dependencies
- Python 3.7+
- `yaml` (PyYAML) - YAML parsing
- `artifact.define` skill - Artifact registry
## Status
**Active** - Phase 2 implementation complete
## Tags
artifacts, validation, quality, schema, tier2, phase2
## Version History
- **0.1.0** (2025-10-25): Initial implementation
- Syntax validation (YAML/Markdown)
- Metadata completeness checking
- Required section verification
- TODO marker detection
- Quality scoring
- Strict mode
- JSON schema support (framework)

and generates prioritized recommendations for optimization.
features:
- Automatic build system detection
- Dependency impact analysis
- Caching configuration review
- Bundle size and code splitting analysis
- TypeScript compilation optimization
- Parallel processing recommendations
- Estimated improvement calculations
usage: |
Basic usage:
python3 skills/build.optimize/build_optimize.py
For specific project:
python3 skills/build.optimize/build_optimize.py /path/to/project
Machine-readable output:
python3 skills/build.optimize/build_optimize.py --format=json
best_practices:
- Run analysis before making changes to establish baseline
- Address high-priority recommendations first
- Test build times before and after optimizations
- Keep cache directories in .gitignore
- Enable caching in CI/CD pipelines
troubleshooting:
- If build system not detected, ensure package.json exists
- Some optimizations require manual configuration file edits
- TypeScript analysis requires valid tsconfig.json
- Results are most accurate with complete project structure

# code.format
Format code using Prettier, supporting multiple languages and file types. This skill can format individual files or entire directories, check formatting without making changes, and respect custom Prettier configurations.
## Overview
**Purpose:** Automatically format code using Prettier to maintain consistent code style across your project.
**Command:** `/code/format`
**Version:** 0.1.0
## Features
- Format individual files or entire directories
- Support for 15+ file types (JavaScript, TypeScript, CSS, HTML, JSON, YAML, Markdown, and more)
- Auto-detect Prettier configuration files (.prettierrc, prettier.config.js, etc.)
- Check-only mode to validate formatting without modifying files
- Custom file pattern filtering
- Detailed formatting reports
- Automatic discovery of local and global Prettier installations
## Supported File Types
- **JavaScript**: .js, .jsx, .mjs, .cjs
- **TypeScript**: .ts, .tsx
- **CSS/Styles**: .css, .scss, .less
- **HTML**: .html, .htm
- **JSON**: .json
- **YAML**: .yaml, .yml
- **Markdown**: .md, .mdx
- **GraphQL**: .graphql, .gql
- **Vue**: .vue
## Prerequisites
Prettier must be installed either globally or locally in your project:
```bash
# Global installation
npm install -g prettier
# Or local installation (recommended)
npm install --save-dev prettier
```
## Usage
### Basic Usage
Format a single file:
```bash
python3 skills/code.format/code_format.py --path src/index.js
```
Format an entire directory:
```bash
python3 skills/code.format/code_format.py --path src/
```
### Advanced Usage
**Check formatting without modifying files:**
```bash
python3 skills/code.format/code_format.py --path src/ --check
```
**Format only specific file types:**
```bash
python3 skills/code.format/code_format.py --path src/ --patterns "**/*.ts,**/*.tsx"
```
**Use custom Prettier configuration:**
```bash
python3 skills/code.format/code_format.py --path src/ --config-path .prettierrc.custom
```
**Dry run (check without writing):**
```bash
python3 skills/code.format/code_format.py --path src/ --no-write
```
**Output as YAML:**
```bash
python3 skills/code.format/code_format.py --path src/ --output-format yaml
```
## CLI Arguments
| Argument | Required | Default | Description |
|----------|----------|---------|-------------|
| `--path` | Yes | - | File or directory path to format |
| `--config-path` | No | Auto-detect | Path to custom Prettier configuration file |
| `--check` | No | false | Only check formatting without modifying files |
| `--patterns` | No | All supported | Comma-separated glob patterns (e.g., "**/*.js,**/*.ts") |
| `--no-write` | No | false | Don't write changes (dry run mode) |
| `--output-format` | No | json | Output format: json or yaml |
## Configuration
The skill will automatically search for Prettier configuration files in this order:
1. Custom config specified via `--config-path`
2. `.prettierrc` in the target directory or parent directories
3. `.prettierrc.json`, `.prettierrc.yml`, `.prettierrc.yaml`
4. `.prettierrc.js`, `.prettierrc.cjs`
5. `prettier.config.js`, `prettier.config.cjs`
6. Prettier defaults if no config found
## Output Format
The skill returns a JSON object with detailed formatting results:
```json
{
"ok": true,
"status": "success",
"message": "Formatted 5 files. 3 already formatted.",
"formatted_count": 5,
"already_formatted_count": 3,
"needs_formatting_count": 0,
"checked_count": 8,
"error_count": 0,
"files_formatted": [
"src/components/Header.tsx",
"src/utils/helpers.js"
],
"files_already_formatted": [
"src/index.ts",
"src/App.tsx",
"src/config.json"
],
"files_need_formatting": [],
"files_with_errors": []
}
```
### Response Fields
- **ok**: Boolean indicating overall success
- **status**: Status string ("success" or "failed")
- **message**: Human-readable summary
- **formatted_count**: Number of files that were formatted
- **already_formatted_count**: Number of files that were already properly formatted
- **needs_formatting_count**: Number of files that need formatting (check mode only)
- **checked_count**: Total number of files processed
- **error_count**: Number of files that encountered errors
- **files_formatted**: List of files that were formatted
- **files_already_formatted**: List of files that were already formatted
- **files_need_formatting**: List of files needing formatting (check mode)
- **files_with_errors**: List of files with errors and error messages
## Error Handling
The skill gracefully handles various error scenarios:
- **Prettier not installed**: Clear error message with installation instructions
- **Invalid path**: Validation error if path doesn't exist
- **Syntax errors**: Reports files with syntax errors without stopping
- **Permission errors**: Reports files that couldn't be read/written
- **Timeouts**: 30-second timeout per file with clear error reporting
## Integration with Agents
Include this skill in your agent's configuration:
```yaml
name: my.agent
version: 1.0.0
skills_available:
- code.format
```
Then invoke it programmatically:
```python
from skills.code_format.code_format import CodeFormat
formatter = CodeFormat()
result = formatter.execute(
path="src/",
check_only=True,
file_patterns="**/*.{ts,tsx}"
)
if result["ok"]:
print(f"Checked {result['checked_count']} files")
print(f"{result['needs_formatting_count']} files need formatting")
```
## Examples
### Example 1: Format a React Project
```bash
python3 skills/code.format/code_format.py \
--path src/ \
--patterns "**/*.{js,jsx,ts,tsx,css,json}"
```
### Example 2: Pre-commit Check
```bash
python3 skills/code.format/code_format.py \
--path src/ \
--check \
--output-format json
# Exit code 0 if all files formatted, 1 otherwise
```
### Example 3: Format Only Changed Files
```bash
# Get changed files from git
CHANGED_FILES=$(git diff --name-only --diff-filter=ACMR | grep -E '\.(js|ts|jsx|tsx)$' | tr '\n' ',')
# Format only those files
python3 skills/code.format/code_format.py \
--path . \
--patterns "$CHANGED_FILES"
```
## Testing
Run the test suite:
```bash
pytest skills/code.format/test_code_format.py -v
```
Run specific tests:
```bash
pytest skills/code.format/test_code_format.py::TestCodeFormat::test_single_file -v
```
## Permissions
This skill requires the following permissions:
- **filesystem:read** - To read files and configurations
- **filesystem:write** - To write formatted files
- **process:execute** - To run the Prettier command
## Artifact Metadata
**Produces:**
- `formatting-report` (application/json) - Detailed formatting operation results
## Troubleshooting
**Issue**: "Prettier is not installed"
- **Solution**: Install Prettier globally (`npm install -g prettier`) or locally in your project
**Issue**: No files found to format
- **Solution**: Check your file patterns and ensure files exist in the target path
**Issue**: Configuration file not found
- **Solution**: Ensure your config file exists and the path is correct, or let it auto-detect
**Issue**: Timeout errors
- **Solution**: Very large files may timeout (30s limit). Format them individually or increase timeout in code
## Created By
This skill was generated by **meta.skill**, the skill creator meta-agent, and enhanced with full Prettier integration.

description: Validates and registers command manifest files (YAML) to integrate new slash commands into Betty.

# command.define Skill
Validates and registers command manifest files (YAML) to integrate new slash commands into Betty.
## Purpose
The `command.define` skill acts as the "compiler" for Betty Commands. It ensures a command manifest meets all schema requirements and then updates the Command Registry (`/registry/commands.json`) with the new command.
This skill is part of Betty's Layer 1 (Commands) infrastructure, enabling developers to create user-facing slash commands that delegate to agents, workflows, or skills.
## Usage
```bash
python skills/command.define/command_define.py <path_to_command.yaml>
```
### Arguments
| Argument | Type | Required | Description |
|----------|------|----------|-------------|
| manifest_path | string | Yes | Path to the command manifest YAML to validate and register |
## Behavior
1. **Schema Validation** – Checks that required fields (`name`, `version`, `description`, `execution`) are present and correctly formatted (e.g., name must start with `/`).
2. **Parameter Verification** – Verifies each parameter in the manifest has `name`, `type`, and `description`, and that the execution target (agent/skill/workflow) actually exists in the system.
3. **Registry Update** – On success, adds the command entry to `/registry/commands.json` with status `active`.
## Validation Rules
### Required Fields
- **name**: Command name (must start with `/`, e.g., `/api-design`)
- **version**: Semantic version (e.g., `0.1.0`)
- **description**: Human-readable description of what the command does
- **execution**: Object specifying how to execute the command
### Execution Configuration
The `execution` field must contain:
- **type**: One of `skill`, `agent`, or `workflow`
- **target**: Name of the skill/agent/workflow to invoke
- For skills: Must exist in `/registry/skills.json`
- For agents: Must exist in `/registry/agents.json`
- For workflows: File must exist at `/workflows/{target}.yaml`
### Optional Fields
- **parameters**: Array of parameter objects, each with:
- `name` (required): Parameter name
- `type` (required): Parameter type (string, number, boolean, etc.)
- `required` (optional): Whether parameter is required
- `description` (optional): Parameter description
- `default` (optional): Default value
- **status**: Command status (`draft` or `active`, defaults to `draft`)
- **tags**: Array of tags for categorization
## Outputs
### Success Response
```json
{
"ok": true,
"status": "registered",
"errors": [],
"path": "commands/hello.yaml",
"details": {
"valid": true,
"status": "registered",
"registry_updated": true,
"manifest": {
"name": "/hello",
"version": "0.1.0",
"description": "Prints Hello World",
"execution": {
"type": "skill",
"target": "test.hello"
}
}
}
}
```
### Failure Response
```json
{
"ok": false,
"status": "failed",
"errors": [
"Skill 'test.hello' not found in skill registry"
],
"path": "commands/hello.yaml",
"details": {
"valid": false,
"errors": [
"Skill 'test.hello' not found in skill registry"
],
"path": "commands/hello.yaml"
}
}
```
## Example
### Valid Command Manifest
```yaml
# commands/api-design.yaml
name: /api-design
version: 0.1.0
description: "Design a new API following enterprise guidelines"
parameters:
- name: service_name
type: string
required: true
description: "Name of the service/API"
- name: spec_type
type: string
required: false
default: openapi
description: "Type of API specification (openapi or asyncapi)"
execution:
type: agent
target: api.designer
status: active
tags: [api, design, enterprise]
```
### Running the Validator
```bash
$ python skills/command.define/command_define.py commands/api-design.yaml
{
"ok": true,
"status": "registered",
"errors": [],
"path": "commands/api-design.yaml",
"details": {
"valid": true,
"status": "registered",
"registry_updated": true
}
}
```
### Invalid Command Example
If the target agent doesn't exist:
```bash
$ python skills/command.define/command_define.py commands/hello.yaml
{
"ok": false,
"status": "failed",
"errors": [
"Agent 'api.designer' not found in agent registry"
],
"path": "commands/hello.yaml"
}
```
## Integration
### With Workflows
Commands can be validated as part of a workflow:
```yaml
# workflows/register_command.yaml
steps:
- skill: command.define
args:
- "commands/my-command.yaml"
required: true
```
### With Hooks
Validate commands automatically when they're edited:
```bash
# Create a hook that validates command manifests on save
python skills/hook.define/hook_define.py \
--event on_file_save \
--pattern "commands/**/*.yaml" \
--command "python skills/command.define/command_define.py" \
--blocking true
```
## Common Errors
| Error | Cause | Solution |
|-------|-------|----------|
| "Missing required fields: name" | Command manifest missing `name` field | Add `name` field with value starting with `/` |
| "Invalid name: Command name must start with /" | Name doesn't start with `/` | Update name to start with `/` (e.g., `/api-design`) |
| "Skill 'X' not found in skill registry" | Referenced skill doesn't exist | Register the skill first using `skill.define` or fix the target name |
| "Agent 'X' not found in agent registry" | Referenced agent doesn't exist | Register the agent first using `agent.define` or fix the target name |
| "Workflow file not found" | Referenced workflow file doesn't exist | Create the workflow file at `/workflows/{target}.yaml` |
| "execution.type is required" | Missing execution type | Add `execution.type` field with value `skill`, `agent`, or `workflow` |

- **agent.define** – for validating and registering agents that commands can invoke
- **hook.define** – for creating validation hooks that can trigger command validation
## Exit Codes
- **0**: Success (manifest valid and registered)
- **1**: Failure (validation errors or registry update failed)
## Files Modified
- **Registry**: `/registry/commands.json` – updated with new or modified command entry
- **Logs**: Command validation and registration logged to Betty's logging system
## Dependencies
- **Skill Registry** (`/registry/skills.json`) – for validating skill targets
- **Agent Registry** (`/registry/agents.json`) – for validating agent targets
- **Workflow Files** (`/workflows/*.yaml`) – for validating workflow targets
## Status
**Active** – This skill is production-ready and actively used in Betty's command infrastructure.
## Version History
- **0.1.0** (Oct 2025) – Initial implementation with full validation and registry management

# data.transform
Transform data between different formats (JSON, YAML, XML, CSV) with validation and error handling
## Overview
**Purpose:** Transform data between different formats (JSON, YAML, XML, CSV) with validation and error handling
**Command:** `/data/transform`
## Usage
### Basic Usage
```bash
python3 skills/data/transform/data_transform.py
```
### With Arguments
```bash
python3 skills/data/transform/data_transform.py \
--input_file_path "value" \
--source_format "value" \
--target_format "value" \
--schema_path_(optional) "value" \
--output-format json
```
## Inputs
- **input_file_path**
- **source_format**
- **target_format**
- **schema_path (optional)**
## Outputs
- **transformed_file**
- **transformation_report.json**
## Artifact Metadata
### Produces
- `transformed-data`
- `transformation-report`
## Permissions

- `filesystem:write`
## Implementation Notes
Support transformations between: - JSON ↔ YAML - JSON ↔ XML - JSON ↔ CSV - YAML ↔ XML - XML ↔ CSV Features: - Validate input against schema before transformation - Preserve data types during conversion - Handle nested structures appropriately - Report data loss warnings (e.g., CSV can't represent nesting) - Support custom transformation rules - Provide detailed error messages Output report should include: - Transformation success status - Source and target formats - Data validation results - Warnings about potential data loss - Transformation time and file sizes
## Integration
This skill can be used in agents by including it in `skills_available`:
```yaml
name: my.agent
skills_available:
- data.transform
```
## Testing
Run tests with:
```bash
pytest skills/data/transform/test_data_transform.py -v
```

# docs.expand.glossary
**Version**: 0.1.0
**Status**: active
## Overview
The `docs.expand.glossary` skill automatically discovers undocumented terms from Betty manifests and documentation, then enriches `glossary.md` with auto-generated definitions. This ensures comprehensive documentation coverage and helps maintain consistency across the Betty ecosystem.
## Purpose
- Extract field names and values from `skill.yaml` and `agent.yaml` manifests
- Scan markdown documentation for capitalized terms that may need definitions
- Identify gaps in the existing glossary
- Auto-generate definitions for common technical terms
- Update `glossary.md` with new entries organized alphabetically
- Emit JSON summary of changes for auditing
## Inputs
| Name | Type | Required | Default | Description |
|------|------|----------|---------|-------------|
| `glossary_path` | string | No | `docs/glossary.md` | Path to the glossary file to expand |
| `base_dir` | string | No | Project root | Base directory to scan for manifests |
| `dry_run` | boolean | No | `false` | Preview changes without writing to file |
| `include_auto_generated` | boolean | No | `true` | Include auto-generated definitions |
## Outputs
| Name | Type | Description |
|------|------|-------------|
| `summary` | object | Summary with counts, file paths, and operation metadata |
| `new_definitions` | object | Dictionary mapping new terms to their definitions |
| `manifest_terms` | object | Categorized terms extracted from manifests |
| `skipped_terms` | array | Terms that were skipped (already documented or too common) |
## What Gets Scanned
### Manifest Files
**skill.yaml fields:**
- `status` values (active, draft, deprecated, archived)
- `runtime` values (python, javascript, bash)
- `permissions` (filesystem:read, filesystem:write, network:http)
- Input/output `type` values
- `entrypoints` parameters
**agent.yaml fields:**
- `reasoning_mode` (iterative, oneshot)
- `status` values
- `capabilities`
- Error handling strategies (on_validation_failure, etc.)
- Timeout and retry configurations
### Documentation
- Scans all `docs/*.md` files for capitalized multi-word phrases
- Identifies technical terms that may need glossary entries
- Filters out common words and overly generic terms
## How It Works
1. **Load Existing Glossary**: Parses `glossary.md` to identify already-documented terms
2. **Scan Manifests**: Recursively walks `skills/` and `agents/` directories for YAML files
3. **Extract Terms**: Collects field names, values, and configuration options from manifests
4. **Scan Docs**: Looks for capitalized terms in markdown documentation
5. **Generate Definitions**: Creates concise, accurate definitions for common technical terms
6. **Update Glossary**: Inserts new terms alphabetically into appropriate sections
7. **Report**: Returns JSON summary with all changes and statistics
## Auto-Generated Definitions
The skill includes predefined definitions for common terms:
- **Status values**: active, draft, deprecated, archived
- **Runtimes**: python, javascript, bash
- **Permissions**: filesystem:read, filesystem:write, network:http
- **Reasoning modes**: iterative, oneshot
- **Types**: string, boolean, integer, object, array
- **Configuration**: max_retries, timeout_seconds, blocking, fuzzy
- **Modes**: dry_run, strict, overwrite
For unknown terms, the skill can generate contextual definitions based on category and usage patterns.
## Usage Examples
### Basic Usage
```bash
# Expand glossary with all undocumented terms
python glossary_expand.py
# Preview changes without writing
python glossary_expand.py --dry-run
# Use custom glossary location
python glossary_expand.py --glossary-path /path/to/glossary.md
```
### Programmatic Usage
```python
from skills.docs.expand.glossary.glossary_expand import expand_glossary
# Expand glossary
result = expand_glossary(
glossary_path="docs/glossary.md",
dry_run=False,
include_auto_generated=True
)
# Check results
if result['ok']:
summary = result['details']['summary']
print(f"Added {summary['new_terms_count']} new terms")
print(f"New terms: {summary['new_terms']}")
```
### Output Format
#### Summary Mode (Default)
```
================================================================================

### As a Hook
Can be integrated as a pre-commit hook to ensure glossary stays current:
```yaml
# .claude/hooks.yaml
- name: glossary-completeness-check
event: on_commit
command: python skills/docs.expand.glossary/glossary_expand.py --dry-run
blocking: false
```
## Skipped Terms
The skill automatically skips:
- Terms already in the glossary
- Common words (name, version, description, etc.)
- Generic types (string, boolean, file, path, etc.)
- Single-character or overly generic terms
## Limitations
- Auto-generated definitions may need manual refinement for domain-specific terms
- Complex or nuanced terms may require human review
- Alphabetical insertion may need manual adjustment for optimal organization
- Does not detect duplicate or inconsistent definitions
## Future Enhancements
- Detect and flag duplicate definitions
- Identify outdated or inconsistent glossary entries
- Generate contextual definitions using LLM analysis
- Support for multi-language glossaries
- Integration with documentation linting tools
## Dependencies
- `context.schema` - For validating manifest structure
## Tags
`documentation`, `glossary`, `automation`, `analysis`, `manifests`
## Related Skills
- `generate.docs` - Generate SKILL.md documentation from manifests
- `registry.query` - Query registries for specific terms and metadata
- `skill.define` - Define and register new skills

# docs.lint.links
## Overview
**docs.lint.links** validates Markdown links to detect broken internal or external links, with optional autofix mode to correct common issues.
## Purpose
This skill helps maintain documentation quality by:
- Scanning all `.md` files in a repository
- Detecting broken external links (404s and other HTTP errors)
- Detecting broken internal links (relative paths that don't resolve)
- Providing suggested fixes for common issues
- Automatically fixing case mismatches and `.md` extension issues
## Usage
### Basic Usage
```bash
python skills/docs.lint.links/docs_link_lint.py [root_dir] [options]
```
### Parameters
| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `root_dir` | string | No | `.` | Root directory to search for Markdown files |
| `--no-external` | boolean | No | false | Skip checking external links (faster) |
| `--autofix` | boolean | No | false | Automatically fix common issues (case mismatches, .md extension issues) |
| `--timeout` | integer | No | `10` | Timeout for external link checks in seconds |
| `--exclude` | string | No | - | Comma-separated list of patterns to exclude (e.g., 'node_modules,.git') |
| `--output` | string | No | `json` | Output format (json or text) |
## Outputs
| Output | Type | Description |
|--------|------|-------------|
| `lint_results` | object | JSON object containing link validation results with issues and statistics |
| `issues` | array | Array of link issues found, each with file, line, link, issue type, and suggested fix |
| `summary` | object | Summary statistics including files checked, issues found, and fixes applied |
## Usage Examples
### Example 1: Basic Link Validation
Check all markdown files in the current directory for broken links:
```bash
python skills/docs.lint.links/docs_link_lint.py
```
### Example 2: Skip External Link Checks
Check only internal links (much faster):
```bash
python skills/docs.lint.links/docs_link_lint.py --no-external
```
### Example 3: Auto-fix Common Issues
Automatically fix case mismatches and `.md` extension issues:
```bash
python skills/docs.lint.links/docs_link_lint.py --autofix
```
### Example 4: Check Specific Directory
Check markdown files in the `docs` directory:
```bash
python skills/docs.lint.links/docs_link_lint.py docs/
```
### Example 5: Exclude Patterns
Exclude certain directories from checking:
```bash
python skills/docs.lint.links/docs_link_lint.py --exclude "node_modules,vendor,.venv"
```
### Example 6: Text Output
Get human-readable text output instead of JSON:
```bash
python skills/docs.lint.links/docs_link_lint.py --output text
```
### Example 7: Custom Timeout
Use a longer timeout for external link checks:
```bash
python skills/docs.lint.links/docs_link_lint.py --timeout 30
```
## Output Format
### JSON Output (Default)
```json
{
"status": "success",
"summary": {
"files_checked": 42,
"files_with_issues": 3,
"total_issues": 5,
"autofix_enabled": false,
"total_fixes_applied": 0
},
"issues": [
{
"file": "docs/api.md",
"line": 15,
"link": "../README.MD",
"issue_type": "internal_broken",
"message": "File not found: ../README.MD (found case mismatch: README.md)",

"line": 23,
"link": "https://example.com/missing",
"issue_type": "external_broken",
"message": "External link is broken: HTTP 404"
}
]
}
```
### Text Output
```
Markdown Link Lint Results
==================================================
Files checked: 42
Files with issues: 3
Total issues: 5
Issues found:
--------------------------------------------------
docs/api.md:15
Link: ../README.MD
Issue: File not found: ../README.MD (found case mismatch: README.md)
Suggested fix: ../README.md
docs/guide.md:23
Link: https://example.com/missing
Issue: External link is broken: HTTP 404
```
## Issue Types
### Internal Broken Links
These are relative file paths that don't resolve:
- **Case mismatches**: `README.MD` when file is `README.md`
- **Missing `.md` extension**: `guide` when file is `guide.md`
- **Extra `.md` extension**: `file.md` when file is `file`
- **File not found**: Path doesn't exist in the repository
### External Broken Links
These are HTTP/HTTPS URLs that return errors:
- **404 Not Found**: Page doesn't exist
- **403 Forbidden**: Access denied
- **500+ Server Errors**: Server-side issues
- **Timeout**: Server didn't respond in time
- **Network errors**: DNS failures, connection refused, etc.
## Autofix Behavior
When `--autofix` is enabled, the skill will automatically correct:
1. **Case mismatches**: If a link uses wrong case but a case-insensitive match exists
2. **Missing `.md` extension**: If a link is missing `.md` but the file exists with it
3. **Extra `.md` extension**: If a link has `.md` but the file exists without it
The autofix preserves:
- Anchor fragments (e.g., `#section`)
- Query parameters (e.g., `?version=1.0`)
**Note**: Autofix modifies files in place. It's recommended to use version control or create backups before using this option.
## Link Detection
The skill detects the following link formats:
1. **Standard markdown links**: `[text](url)`
2. **Angle bracket URLs**: `<https://example.com>`
3. **Reference-style links**: `[text][ref]` with `[ref]: url` definitions
4. **Implicit reference links**: `[text][]` using text as reference
## Excluded Patterns
By default, the following patterns are excluded from scanning:
- `.git/`
- `node_modules/`
- `.venv/` and `venv/`
- `__pycache__/`
Additional patterns can be excluded using the `--exclude` parameter.
## Integration Examples
### Use in CI/CD
Add to your CI pipeline to catch broken links:
```yaml
# .github/workflows/docs-lint.yml
name: Documentation Link Check
on: [push, pull_request]
jobs:
lint-docs:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Check documentation links
run: |
python skills/docs.lint.links/docs_link_lint.py --no-external
```
### Use with Pre-commit Hook
Add to `.git/hooks/pre-commit`:
```bash
#!/bin/bash
python skills/docs.lint.links/docs_link_lint.py --no-external --output text
if [ $? -ne 0 ]; then
echo "Documentation has broken links. Please fix before committing."
exit 1
fi
```
### Use in Documentation Workflow
```yaml
# workflows/documentation.yaml
steps:
- skill: docs.lint.links
args:
- "docs/"
- "--autofix"
- skill: docs.lint.links

- "--output=text"
```
## Performance Considerations
### External Link Checking
Checking external links can be slow because:
- Each link requires an HTTP request
- Some servers may rate-limit or block automated requests
- Network latency and timeouts add up
**Recommendations**:
- Use `--no-external` for fast local checks
- Use `--timeout` to adjust timeout for slow networks
- Run external checks less frequently (e.g., nightly builds)
### Large Repositories
For repositories with many markdown files:
- Use `--exclude` to skip irrelevant directories
- Consider checking specific subdirectories instead of the entire repo
- The skill automatically skips common directories like `node_modules`
## Error Handling
The skill returns:
- Exit code `0` if no broken links are found
- Exit code `1` if broken links are found or an error occurs
This makes it suitable for use in CI/CD pipelines and pre-commit hooks.
## Dependencies
_No external dependencies_
All functionality uses Python standard library modules:
- `re` - Regular expression matching for link extraction
- `urllib` - HTTP requests for external link checking
- `pathlib` - File system operations
- `json` - JSON output formatting
## Tags
`documentation`, `linting`, `validation`, `links`, `markdown`

name: Plugin Manifest Sync
description: Reconcile plugin.yaml with Betty Framework registries
---
# docs.sync.plugin_manifest
## Overview
**docs.sync.plugin_manifest** is a validation and reconciliation tool that compares `plugin.yaml` against Betty Framework's registry files to ensure consistency and completeness. It identifies missing commands, orphaned entries, metadata mismatches, and suggests corrections.
## Purpose
Ensures synchronization between:
- **Skill Registry** (`registry/skills.json`) – Active skills with entrypoints
- **Command Registry** (`registry/commands.json`) – Slash commands
- **Plugin Configuration** (`plugin.yaml`) – Claude Code plugin manifest
This skill helps maintain plugin.yaml accuracy by detecting:
- Active skills missing from plugin.yaml
- Orphaned commands in plugin.yaml not found in registries
- Metadata inconsistencies (permissions, runtime, handlers)
- Missing metadata that should be added
## What It Does
1. **Loads Registries**: Reads `skills.json` and `commands.json`
2. **Loads Plugin**: Reads current `plugin.yaml`
3. **Builds Indexes**: Creates lookup tables for both registries and plugin
4. **Compares Entries**: Identifies missing, orphaned, and mismatched commands
5. **Analyzes Metadata**: Checks permissions, runtime, handlers, descriptions
6. **Generates Preview**: Creates `plugin.preview.yaml` with suggested updates
7. **Creates Report**: Outputs `plugin_manifest_diff.md` with detailed analysis
8. **Provides Summary**: Displays key findings and recommendations
## Usage
### Basic Usage
```bash
python skills/docs.sync.plugin_manifest/plugin_manifest_sync.py
```
No arguments required - reads from standard locations.
### Via Betty CLI
```bash
/docs/sync/plugin-manifest
```
### Expected File Structure
```
betty/
├── registry/
│ ├── skills.json # Source of truth for skills
│ └── commands.json # Source of truth for commands
├── plugin.yaml # Current plugin manifest
├── plugin.preview.yaml # Generated preview (output)
└── plugin_manifest_diff.md # Generated report (output)
```
## Behavior
### 1. Registry Loading
Reads and parses:
- `registry/skills.json` – All registered skills
- `registry/commands.json` – All registered commands
Only processes entries with `status: active`.
### 2. Plugin Loading
Reads and parses:
- `plugin.yaml` – Current plugin configuration
Extracts all command definitions.
### 3. Index Building
**Registry Index**: Maps command names to their registry sources
```python
{
"skill/define": {
"type": "skill",
"source": "skill.define",
"skill": {...},
"entrypoint": {...}
},
"api/validate": {
"type": "skill",
"source": "api.validate",
"skill": {...},
"entrypoint": {...}
}
}
```
**Plugin Index**: Maps command names to plugin entries
```python
{
"skill/define": {
"name": "skill/define",
"handler": {...},
"permissions": [...]
}
}
```
### 4. Comparison Analysis
Performs four types of checks:
#### Missing Commands
Commands in registry but not in plugin.yaml:
```
- skill/create (active in registry, missing from plugin)
- api/validate (active in registry, missing from plugin)
```
#### Orphaned Commands
Commands in plugin.yaml but not in registry:
```
- old/deprecated (in plugin but not registered)
- test/removed (in plugin but removed from registry)
```
#### Metadata Mismatches
Commands present in both but with different metadata:
**Runtime Mismatch**:
```
- skill/define:
- Registry: python
- Plugin: node
```
**Permission Mismatch**:
```
- api/validate:
- Missing: filesystem:read
- Extra: network:write
```
**Handler Mismatch**:
```
- skill/create:
- Registry: skills/skill.create/skill_create.py
- Plugin: skills/skill.create/old_handler.py
```
**Description Mismatch**:
```
- agent/run:
- Registry: "Execute a Betty agent..."
- Plugin: "Run agent"
```
#### Missing Metadata Suggestions
Identifies registry entries missing recommended metadata:
```
- hook/define: Consider adding permissions metadata
- test/skill: Consider adding description
```
### 5. Preview Generation
Creates `plugin.preview.yaml` by:
- Taking all active commands from registries
- Converting to plugin.yaml format
- Including all metadata from registries
- Adding generation timestamp
- Preserving existing plugin metadata (author, license, etc.)
### 6. Report Generation
Creates `plugin_manifest_diff.md` with:
- Executive summary
- Lists of missing commands
- Lists of orphaned commands
- Detailed metadata issues
- Metadata suggestions
## Outputs
### Success Response
```json
{
"ok": true,
"status": "success",
"preview_path": "/home/user/betty/plugin.preview.yaml",
"report_path": "/home/user/betty/plugin_manifest_diff.md",

```bash
# Make some registry updates
/skill/define skills/new.skill/skill.yaml
# Check for discrepancies
/docs/sync/plugin-manifest
# Review the report
cat plugin_manifest_diff.md
# If changes look good, apply them
cp plugin.preview.yaml plugin.yaml
```

### Example 3: Finding Metadata Mismatches
**Scenario**: Registry was updated but plugin.yaml wasn't synced
```bash
# Update skill permissions in registry
/skill/define skills/api.validate/skill.yaml
# Check for differences
/docs/sync/plugin-manifest
# Review specific mismatches
grep -A 5 "Metadata Issues" plugin_manifest_diff.md
```
**Report Output**:
```markdown
## Metadata Issues
- **api/validate**: Permissions Mismatch
- Missing: network:http
- Extra: filesystem:write
```
### Example 4: Pre-Commit Validation
**Scenario**: Validate plugin.yaml before committing changes
```bash
# Before committing
/docs/sync/plugin-manifest
# If discrepancies found, fix them
if [ $? -eq 0 ]; then
# Review and apply changes
diff plugin.yaml plugin.preview.yaml
cp plugin.preview.yaml plugin.yaml
fi
# Commit changes
git add plugin.yaml
git commit -m "Sync plugin.yaml with registries"
```
### Example 5: CI/CD Integration
**Scenario**: Automated validation in CI pipeline
```yaml
# .github/workflows/validate-plugin.yml
name: Validate Plugin Manifest
on: [push, pull_request]
jobs:
validate:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Reconcile Plugin Manifest
run: |
python skills/docs.sync.plugin_manifest/plugin_manifest_sync.py
# Check if there are discrepancies
if grep -q "Missing from plugin.yaml: [1-9]" plugin_manifest_diff.md; then
echo "❌ Plugin manifest has missing commands"
cat plugin_manifest_diff.md
exit 1
fi
if grep -q "Orphaned in plugin.yaml: [1-9]" plugin_manifest_diff.md; then
echo "❌ Plugin manifest has orphaned commands"
cat plugin_manifest_diff.md
exit 1
fi
echo "✅ Plugin manifest is in sync"
```
## Integration
### With plugin.sync
Use reconciliation to verify before syncing:
```bash
# Check current state
/docs/sync/plugin-manifest
# Review differences
cat plugin_manifest_diff.md
# If satisfied, run full sync
/plugin/sync
```
### With skill.define
Validate after defining skills:
```bash
# Define new skill
/skill/define skills/my.skill/skill.yaml
# Check plugin consistency
/docs/sync/plugin-manifest
# Apply changes if needed
cp plugin.preview.yaml plugin.yaml
```
### With Hooks
Auto-check on registry changes:
```yaml
# .claude/hooks.yaml
- event: on_file_save
pattern: "registry/*.json"
command: python skills/docs.sync.plugin_manifest/plugin_manifest_sync.py
blocking: false
description: Check plugin manifest sync when registries change
```
### With Workflows
Include in skill lifecycle workflow:
```yaml
# workflows/update_plugin.yaml
steps:
- skill: skill.define
args: ["skills/new.skill/skill.yaml"]
- skill: docs.sync.plugin_manifest
args: []
- skill: plugin.sync
args: []
```
## What Gets Reported
### ✅ Detected Issues
- Active skills missing from plugin.yaml
- Orphaned commands in plugin.yaml
- Runtime mismatches (python vs node)
- Permission mismatches (missing or extra)
- Handler path mismatches
- Description mismatches
- Missing metadata (permissions, descriptions)
### ❌ Not Detected
- Draft/inactive skills (intentionally excluded)
- Malformed YAML syntax (causes failure)
- Handler file existence (use plugin.sync for that)
- Parameter schema validation
## Common Use Cases
| Use Case | When to Use |
|----------|-------------|
| **Pre-commit check** | Before committing plugin.yaml changes |
| **Post-registry update** | After adding/updating skills in registry |
| **CI/CD validation** | Automated pipeline checks |
| **Manual audit** | Periodic manual review of plugin state |
| **Debugging** | When commands aren't appearing as expected |
| **Migration** | After major registry restructuring |
## Common Errors
| Error | Cause | Solution |
|-------|-------|----------|
| "Failed to parse JSON" | Invalid JSON in registry | Fix JSON syntax in registry files |
| "Failed to parse YAML" | Invalid YAML in plugin.yaml | Fix YAML syntax in plugin.yaml |
| "Registry file not found" | Missing registry files | Ensure registries exist in registry/ |
| "Permission denied" | Cannot write output files | Check write permissions on directory |
| All commands missing | Empty or invalid registries | Verify registry files are populated |
## Files Read
- `registry/skills.json` – Skill registry (source of truth)
- `registry/commands.json` – Command registry (source of truth)
- `plugin.yaml` – Current plugin manifest (for comparison)
## Files Generated
- `plugin.preview.yaml` – Updated plugin manifest preview
- `plugin_manifest_diff.md` – Detailed reconciliation report
## Exit Codes
- **0**: Success (reconciliation completed successfully)
- **1**: Failure (error during reconciliation)
Note: Discrepancies found are reported but don't cause failure (exit 0). Only parsing errors or system failures cause exit 1.
## Logging
Logs reconciliation progress:
```
INFO: Starting plugin manifest reconciliation...
INFO: Loading registry files...
INFO: Loading plugin.yaml...
INFO: Building registry index...
INFO: Building plugin index...
INFO: Comparing registries with plugin.yaml...
INFO: Reconciling registries with plugin.yaml...
INFO: Generating updated plugin.yaml...
INFO: ✅ Written file to /home/user/betty/plugin.preview.yaml
INFO: Generating diff report...
INFO: ✅ Written diff report to /home/user/betty/plugin_manifest_diff.md
```
## Best Practices
1. **Run Before Committing**: Always check sync status before committing plugin.yaml
2. **Review Diff Report**: Read the full report to understand all changes
3. **Validate Preview**: Review plugin.preview.yaml before applying
4. **Include in CI**: Add validation to your CI/CD pipeline
5. **Regular Audits**: Run periodic checks even without changes
6. **Address Orphans**: Remove orphaned commands promptly
7. **Fix Mismatches**: Resolve metadata mismatches to maintain consistency
8. **Keep Registries Clean**: Mark inactive skills as draft instead of deleting
## Workflow Integration
### Recommended Workflow
```bash
# 1. Define or update skills
/skill/define skills/my.skill/skill.yaml
# 2. Check for discrepancies
/docs/sync/plugin-manifest
# 3. Review the report
cat plugin_manifest_diff.md
# 4. Review the preview
diff plugin.yaml plugin.preview.yaml
# 5. Apply changes if satisfied
cp plugin.preview.yaml plugin.yaml
# 6. Commit changes
git add plugin.yaml registry/
git commit -m "Update plugin manifest"
```
### Alternative: Auto-Sync Workflow
```bash
# 1. Define or update skills
/skill/define skills/my.skill/skill.yaml
# 2. Run full sync (overwrites plugin.yaml)
/plugin/sync
# 3. Validate the result
/docs/sync/plugin-manifest
# 4. If clean, commit
git add plugin.yaml registry/
git commit -m "Update plugin manifest"
```
## Troubleshooting
### Plugin.yaml Shows as Out of Sync
**Problem**: Reconciliation reports missing or orphaned commands
**Solutions**:
1. Run `/plugin/sync` to regenerate plugin.yaml from registries
2. Review and apply `plugin.preview.yaml` manually
3. Check if skills are marked as `active` in registry
4. Verify skills have `entrypoints` defined
### Metadata Mismatches Reported
**Problem**: Registry and plugin have different permissions/runtime/handlers
**Solutions**:
1. Update skill.yaml with correct metadata
2. Run `/skill/define` to register changes
3. Run `/docs/sync/plugin-manifest` to verify
4. Apply plugin.preview.yaml or run `/plugin/sync`
### Orphaned Commands Found
**Problem**: Commands in plugin.yaml not found in registry
**Solutions**:
1. Check if skill was removed from registry
2. Verify skill status is `active` in registry
3. Re-register the skill if it should exist
4. Remove from plugin.yaml if intentionally deprecated
### Preview File Not Generated
**Problem**: plugin.preview.yaml missing after running skill
**Solutions**:
1. Check write permissions on betty/ directory
2. Verify registries are readable
3. Check logs for errors
4. Ensure plugin.yaml exists and is valid
## Architecture
### Skill Category
**Documentation & Infrastructure** – Maintains consistency between registry and plugin configuration layers.
### Design Principles
- **Non-Destructive**: Never modifies plugin.yaml directly
- **Comprehensive**: Reports all types of discrepancies
- **Actionable**: Provides preview file ready to apply
- **Transparent**: Detailed report explains all findings
- **Idempotent**: Can be run multiple times safely

name: Documentation README Sync
description: Automatically regenerate README.md from Betty Framework registries
---
# docs.sync.readme
## Overview
**docs.sync.readme** is the documentation synchronization tool that regenerates the top-level `README.md` to reflect all current registered skills and agents. It ensures that the README stays in sync with the actual state of the Betty Framework by pulling from registry files.
## Purpose
Automates the maintenance of `README.md` to keep documentation accurate and up-to-date with:
- **Skill Registry** (`registry/skills.json`) – All registered skills
- **Agent Registry** (`registry/agents.json`) – All registered agents
This eliminates manual editing of the README and prevents documentation drift as skills and agents are added, modified, or removed.
## What It Does
1. **Reads Registries**: Loads `skills.json` and `agents.json`
2. **Categorizes Skills**: Groups skills by tag/category:
- Foundation (skill.*, registry.*, workflow.*)
- API Development (api.*)
- Infrastructure (agents, commands, hooks, policy)
- Governance (policy, audit)
3. **Updates Sections**:
- Current Core Skills table with categorized skills
- Agents documentation links
- Skills documentation references
4. **Maintains Style**: Preserves README tone, formatting, and structure
5. **Generates Report**: Creates sync report with statistics
## Usage
### Basic Usage
```bash
python skills/docs.sync.readme/readme_sync.py
```
No arguments required - reads from standard registry locations.
### Via Betty CLI
```bash
/docs/sync/readme
```
### Expected Registry Structure
```
betty/
├── registry/
│ ├── skills.json # Skills registry
│ └── agents.json # Agents registry
└── README.md # File to update
```
## Behavior
### 1. Registry Loading
Reads JSON files from:
- `registry/skills.json` – Skills registry
- `registry/agents.json` – Agents registry
If a registry file is missing, logs a warning and continues with empty data.
### 2. Skill Categorization
**Foundation Skills**:
- Matches: `skill.*`, `registry.*`, `workflow.*`
- Examples: `skill.create`, `workflow.compose`
**API Development Skills**:
- Matches: `api.*` or tags: `api`, `openapi`, `asyncapi`
- Examples: `api.define`, `api.validate`
**Infrastructure Skills**:
- Matches tags: `agents`, `command`, `hook`, `policy`, `plugin`
- Examples: `agent.define`, `hook.register`, `plugin.sync`
**Governance Skills**:
- Matches tags: `governance`, `policy`, `audit`
- Examples: `policy.enforce`, `audit.log`
Only **active** skills are included. Test skills (starting with `test.`) are filtered out.
### 3. Skills Section Update
Replaces the "## 🧩 Current Core Skills" section with:
```markdown
## 🧩 Current Core Skills
Betty's self-referential "kernel" of skills bootstraps the rest of the system:
### Foundation Skills
| Skill | Purpose |
|--------|----------|
| **skill.create** | Generates a new Betty Framework Skill directory and manifest. |
| **skill.define** | Validates and registers skill manifests (.skill.yaml) for the Betty Framework. |
| **registry.update** | Updates the Betty Framework Skill Registry by adding or modifying entries. |
### API Development Skills
| Skill | Purpose |
|--------|----------|
| **api.define** | Create OpenAPI and AsyncAPI specifications from templates |
| **api.validate** | Validate OpenAPI and AsyncAPI specifications against enterprise guidelines |
### Infrastructure Skills
| Skill | Purpose |
|--------|----------|
| **agent.define** | Validates and registers agent manifests for the Betty Framework. |
| **hook.define** | Create and register validation hooks for Claude Code |
These skills form the baseline for an **AI-native SDLC** where creation, validation, registration, and orchestration are themselves skills.
```
### 4. Agents Section Update
Updates the "### Agents Documentation" subsection with current agents:
```markdown
### Agents Documentation
Each agent has a `README.md` in its directory:
* [api.designer](agents/api.designer/README.md) — Design RESTful APIs following enterprise guidelines with iterative refinement
* [api.analyzer](agents/api.analyzer/README.md) — Analyze API specifications for backward compatibility and breaking changes
```
Includes both `active` and `draft` agents.
### 5. Report Generation
Creates `sync_report.json` with statistics:
```json
{
"skills_by_category": {
"foundation": 5,
"api": 4,
"infrastructure": 9,
"governance": 1
},
"total_skills": 19,
"agents_count": 2,
"timestamp": "2025-10-23T20:30:00.123456+00:00"
}
```
## Outputs
### Success Response
```json
{
"ok": true,
"status": "success",
"readme_path": "/home/user/betty/README.md",
"report": {
"skills_by_category": {
"foundation": 5,
"api": 4,
"infrastructure": 9,
"governance": 1
},
"total_skills": 19,
"agents_count": 2,
"timestamp": "2025-10-23T20:30:00.123456+00:00"
}
}
```
### Failure Response
```json
{
"ok": false,
"status": "failed",
"error": "README.md not found at /home/user/betty/README.md"
}
```
## What Gets Updated
### ✅ Updated Sections
- **Current Core Skills** (categorized tables)
- **Agents Documentation** (agent links list)
- Skills documentation references
### ❌ Not Modified
- Mission and inspiration
- Purpose and scope
- Repository structure
- Design principles
- Roadmap
- Contributing guidelines
- Requirements
The skill only updates specific documentation sections while preserving all other README content.
## Examples
### Example 1: Sync After Adding New Skills
**Scenario**: You've added several new skills and want to update the README
```bash
# Create and register new skills
/skill/create data.transform "Transform data between formats"
/skill/define skills/data.transform/skill.yaml
/skill/create telemetry.report "Generate telemetry reports"
/skill/define skills/telemetry.report/skill.yaml
# Sync README to include new skills
/docs/sync/readme
```
**Output**:
```
INFO: Starting README.md sync from registries...
INFO: Loading registry files...
INFO: Generating updated README content...
INFO: ✅ Updated README.md
INFO: - Foundation skills: 5
INFO: - API skills: 4
INFO: - Infrastructure skills: 11
INFO: - Governance skills: 1
INFO: - Total active skills: 21
INFO: - Agents: 2
```
### Example 2: Sync After Adding New Agent
**Scenario**: A new agent has been registered and needs to appear in README
```bash
# Define new agent
/agent/define agents/workflow.optimizer/agent.yaml
# Sync README
/docs/sync/readme
```
The new agent will appear in the "### Agents Documentation" section.
### Example 3: Automated Sync in Workflow
**Scenario**: Include README sync as a workflow step after registering skills
```yaml
# workflows/skill_release.yaml
steps:
- skill: skill.define
args: ["skills/new.skill/skill.yaml"]
- skill: plugin.sync
args: []
- skill: docs.sync.readme
args: []
```
This ensures README, plugin.yaml, and registries stay in sync.
## Integration
### With skill.define
After defining skills, sync the README:
```bash
/skill/define skills/my.skill/skill.yaml
/docs/sync/readme
```
### With agent.define
After defining agents, sync the README:
```bash
/agent/define agents/my.agent/agent.yaml
/docs/sync/readme
```
### With Hooks
Auto-sync README when registries change:
```yaml
# .claude/hooks.yaml
- event: on_file_save
pattern: "registry/*.json"
command: python skills/docs.sync.readme/readme_sync.py
blocking: false
description: Auto-sync README when registries change
```
### With plugin.sync
Chain both sync operations:
```bash
/plugin/sync && /docs/sync/readme
```
## Categorization Rules
### Foundation Category
**Criteria**:
- Skill name starts with: `skill.`, `registry.`, `workflow.`
- Core Betty framework functionality
**Examples**:
- `skill.create`, `skill.define`
- `registry.update`, `registry.query`
- `workflow.compose`, `workflow.validate`
### API Category
**Criteria**:
- Skill name starts with: `api.`
- Tags include: `api`, `openapi`, `asyncapi`
**Examples**:
- `api.define`, `api.validate`
- `api.generate-models`, `api.compatibility`
### Infrastructure Category
**Criteria**:
- Tags include: `agents`, `command`, `hook`, `policy`, `plugin`, `registry`
- Infrastructure and orchestration skills
**Examples**:
- `agent.define`, `agent.run`
- `hook.define`, `hook.register`
- `plugin.sync`, `plugin.build`
### Governance Category
**Criteria**:
- Tags include: `governance`, `policy`, `audit`
- Policy enforcement and audit trails
**Examples**:
- `policy.enforce`
- `audit.log`
## Filtering Rules
### ✅ Included
- Skills with `status: active`
- Agents with `status: active` or `status: draft`
- Skills with meaningful descriptions
### ❌ Excluded
- Skills with `status: draft`
- Skills starting with `test.`
- Skills without names or descriptions
## Common Errors
| Error | Cause | Solution |
|-------|-------|----------|
| "README.md not found" | Missing README file | Ensure README.md exists in repo root |
| "Registry file not found" | Missing registry | Run skill.define to populate registry |
| "Failed to parse JSON" | Invalid JSON | Fix JSON syntax in registry files |
## Files Read
- `README.md` – Current README content
- `registry/skills.json` – Skills registry
- `registry/agents.json` – Agents registry
## Files Modified
- `README.md` – Updated with current skills and agents
- `skills/docs.sync.readme/sync_report.json` – Sync statistics
## Exit Codes
- **0**: Success (README updated successfully)
- **1**: Failure (error during sync)
## Logging
Logs sync progress:
```
INFO: Starting README.md sync from registries...
INFO: Loading registry files...
INFO: Generating updated README content...
INFO: ✅ Updated README.md
INFO: - Foundation skills: 5
INFO: - API skills: 4
INFO: - Infrastructure skills: 9
INFO: - Governance skills: 1
INFO: - Total active skills: 19
INFO: - Agents: 2
```
## Best Practices
1. **Run After Registry Changes**: Sync README whenever skills or agents are added/updated
2. **Include in CI/CD**: Add README sync to deployment pipelines
3. **Review Before Commit**: Check updated README before committing changes
4. **Use Hooks**: Set up auto-sync hooks for convenience
5. **Combine with plugin.sync**: Keep both plugin.yaml and README in sync
6. **Version Control**: Always commit README changes with skill/agent changes
## Troubleshooting
### README Not Updating
**Problem**: Changes to registry don't appear in README
**Solutions**:
- Ensure skills have `status: active`
- Check that skill names and descriptions are present
- Verify registry files are valid JSON
- Run `/skill/define` before syncing README
### Skills in Wrong Category
**Problem**: Skill appears in unexpected category
**Solutions**:
- Check skill tags in skill.yaml
- Verify tag categorization rules above
- Add appropriate tags to skill.yaml
- Re-run skill.define to update registry
### Section Markers Not Found
**Problem**: "Section marker not found" warnings
**Solutions**:
- Ensure README has expected section headers
- Check for typos in section headers
- Restore original README structure if modified
- Update section_marker strings in code if intentionally changed
## Architecture
### Skill Categories
**Documentation** – docs.sync.readme maintains the README documentation layer by syncing registry state to the top-level README.
### Design Principles
- **Single Source of Truth**: Registries are the source of truth
- **Preserve Structure**: Only update specific sections
- **Maintain Style**: Keep original tone and formatting
- **Clear Categorization**: Logical grouping of skills by function
- **Idempotent**: Can be run multiple times safely
