# Navigator Initialization Skill

## Purpose

Creates the Navigator documentation structure (`.agent/`) in a new project, copies templates, and sets up initial configuration.

## When This Skill Auto-Invokes

- "Initialize Navigator in this project"
- "Set up Navigator documentation structure"
- "Create .agent folder for Navigator"
- "Bootstrap Navigator for my project"

## What This Skill Does

1. **Checks if already initialized**: Prevents overwriting existing structure
2. **Creates `.agent/` directory structure**:
   ```
   .agent/
   ├── DEVELOPMENT-README.md
   ├── .nav-config.json
   ├── tasks/
   ├── system/
   ├── sops/
   │   ├── integrations/
   │   ├── debugging/
   │   ├── development/
   │   └── deployment/
   └── grafana/
       ├── docker-compose.yml
       ├── prometheus.yml
       ├── grafana-datasource.yml
       ├── grafana-dashboards.yml
       ├── navigator-dashboard.json
       └── README.md
   ```
3. **Copies templates**: DEVELOPMENT-README.md, config, Grafana setup
4. **Auto-detects project info**: Name, tech stack (from package.json if available)
5. **Updates CLAUDE.md**: Adds Navigator-specific instructions to project
6. **Creates .gitignore entries**: Excludes temporary Navigator files

## Execution Steps

### 1. Check if Already Initialized

```bash
if [ -d ".agent" ]; then
    echo "✅ Navigator already initialized in this project"
    echo ""
    echo "To start a session: 'Start my Navigator session'"
    echo "To view documentation: Read .agent/DEVELOPMENT-README.md"
    exit 0
fi
```

### 2. Detect Project Information

Read `package.json`, `pyproject.toml`, `go.mod`, `Cargo.toml`, or similar to extract:
- Project name
- Tech stack
- Dependencies

**Fallback**: Use current directory name if no config found.

### 3. Create Directory Structure

Use Write tool to create:
```
.agent/
.agent/tasks/
.agent/system/
.agent/sops/integrations/
.agent/sops/debugging/
.agent/sops/development/
.agent/sops/deployment/
.agent/grafana/
```

### 4. Copy Templates

Copy from plugin's `templates/` directory to `.agent/`:

**DEVELOPMENT-README.md**:
- Replace `${PROJECT_NAME}` with detected project name
- Replace `${TECH_STACK}` with detected stack
- Replace `${DATE}` with current date

**`.nav-config.json`**:
```json
{
  "version": "4.5.0",
  "project_name": "${PROJECT_NAME}",
  "tech_stack": "${TECH_STACK}",
  "project_management": "none",
  "task_prefix": "TASK",
  "team_chat": "none",
  "auto_load_navigator": true,
  "compact_strategy": "conservative"
}
```

**Grafana Setup**:
Copy all Grafana dashboard files to enable metrics visualization:

```bash
# Find plugin installation directory
PLUGIN_DIR="${HOME}/.claude/plugins/marketplaces/jitd-marketplace"

# Copy Grafana files if plugin has them
if [ -d "${PLUGIN_DIR}/.agent/grafana" ]; then
  cp -r "${PLUGIN_DIR}/.agent/grafana/"* .agent/grafana/
  echo "✓ Grafana dashboard installed"
else
  echo "⚠️  Grafana files not found in plugin"
fi
```

Files copied:
- docker-compose.yml (Grafana + Prometheus stack)
- prometheus.yml (scrape config for Claude Code metrics)
- grafana-datasource.yml (Prometheus datasource config)
- grafana-dashboards.yml (dashboard provider config)
- navigator-dashboard.json (10-panel Navigator metrics dashboard)
- README.md (setup instructions)

### 5. Update Project CLAUDE.md

If `CLAUDE.md` exists:
- Append Navigator-specific sections
- Keep existing project customizations

If `CLAUDE.md` doesn't exist:
- Copy `templates/CLAUDE.md` to project root
- Customize with project info

### 6. Create .gitignore Entries

Add to `.gitignore` if not present:
```
# Navigator context markers
.context-markers/

# Navigator temporary files
.agent/.nav-temp/
```

### 7. Success Message

```
✅ Navigator Initialized Successfully!

Created structure:
  📁 .agent/                    Navigator documentation
  📁 .agent/tasks/              Implementation plans
  📁 .agent/system/             Architecture docs
  📁 .agent/sops/               Standard procedures
  📁 .agent/grafana/            Metrics dashboard
  📄 .agent/.nav-config.json    Configuration
  📄 CLAUDE.md                  Updated with Navigator workflow

Next steps:
  1. Start session: "Start my Navigator session"
  2. Optional: Enable metrics - see .agent/sops/integrations/opentelemetry-setup.md
  3. Optional: Launch Grafana - cd .agent/grafana && docker compose up -d

Documentation: Read .agent/DEVELOPMENT-README.md
```

## Error Handling

**If `.agent/` exists**:
- Don't overwrite
- Show message: "Already initialized"

**If templates not found**:
- Error: "Navigator plugin templates missing. Reinstall plugin."

**If no write permissions**:
- Error: "Cannot create .agent/ directory. Check permissions."

## Predefined Functions

### `project_detector.py`

```python
def detect_project_info(cwd: str) -> dict:
    """
    Detect project name and tech stack from config files.

    Checks (in order):
    1. package.json (Node.js)
    2. pyproject.toml (Python)
    3. go.mod (Go)
    4. Cargo.toml (Rust)
    5. composer.json (PHP)
    6. Gemfile (Ruby)

    Returns:
        {
            "name": "project-name",
            "tech_stack": "Next.js, TypeScript, Prisma",
            "detected_from": "package.json"
        }
    """
```

### `template_customizer.py`

```python
def customize_template(template_content: str, project_info: dict) -> str:
    """
    Replace placeholders in template with project-specific values.

    Placeholders:
    - ${PROJECT_NAME}
    - ${TECH_STACK}
    - ${DATE}
    - ${YEAR}

    Returns customized template content.
    """
```

## Examples

### Example 1: New Next.js Project

**User says**: "Initialize Navigator in this project"

**Skill detects**:
- `package.json` exists
- Name: "my-saas-app"
- Dependencies: next, typescript, prisma

**Result**:
- `.agent/` created
- DEVELOPMENT-README.md shows: "Project: My SaaS App"
- DEVELOPMENT-README.md shows: "Tech Stack: Next.js, TypeScript, Prisma"
- .nav-config.json has project_name: "my-saas-app"

### Example 2: Python Project

**User says**: "Set up Navigator"

**Skill detects**:
- `pyproject.toml` exists
- Name: "ml-pipeline"
- Dependencies: fastapi, pydantic, sqlalchemy

**Result**:
- `.agent/` created
- Tech stack: "FastAPI, Pydantic, SQLAlchemy"

### Example 3: Already Initialized

**User says**: "Initialize Navigator"

**Skill checks**:
- `.agent/` directory exists

**Result**:
```
✅ Navigator already initialized in this project

To start a session: 'Start my Navigator session'
```

## Integration with Other Skills

**nav-start skill**:
- Checks for `.agent/DEVELOPMENT-README.md`
- If missing, suggests: "Initialize Navigator first"

**nav-task skill**:
- Creates tasks in `.agent/tasks/`
- Requires initialization

**nav-sop skill**:
- Creates SOPs in `.agent/sops/`
- Requires initialization

## Version History

- **1.0.0** (2025-01-20): Initial implementation
  - Auto-detection of project info
  - Template customization
  - Grafana setup included
  - Error handling for existing installations

## Notes

- This skill replaces the deleted `/nav:init` command from v2.x
- Templates are copied from plugin installation directory
- Project info detection is best-effort (falls back to directory name)
- Safe to run multiple times (won't overwrite existing structure)
