# Initialize Project Documentation

Generate comprehensive documentation structure for your project based on detected technologies and configuration.

## Your Task

1. **Detect Project Characteristics**:
   - Technology stack (language, frameworks, databases)
   - Project type (web app, CLI, library, microservice, etc.)
   - Infrastructure (Docker, K8s, cloud configs)
   - Database/ORM presence (SQLAlchemy, Prisma, TypeORM, Django, etc.)

2. **Determine Relevant Documentation**:
   - **Core Documentation** (always generate):
     - `docs/architecture.md` - System architecture overview
     - `docs/onboarding.md` - Developer onboarding guide
     - `docs/adr/0001-record-architecture-decisions.md` - First ADR (meta-ADR)

   - **Data Documentation** (if database detected):
     - `docs/data-model.md` - Database schema & ER diagrams

   - **Infrastructure Documentation** (if deployment configs found):
     - `docs/deployment.md` - CI/CD & deployment procedures
     - `docs/security.md` - Security architecture

   - **Development Documentation** (if collaborative project):
     - `docs/contributing.md` - Contribution guidelines
     - `docs/rfc/` - RFC directory for proposals

3. **Check for Existing Documentation**:
   - Scan `docs/` directory
   - If files exist, ask user before overwriting
   - Show what will be created vs what exists

4. **Load Templates**:
   - Templates are in `commands/docs/templates/`
   - Use appropriate template for each document type
   - Replace placeholders with project-specific values

5. **Generate Documentation**:
   - Create `docs/` directory if it doesn't exist
   - Create subdirectories: `docs/adr/`, `docs/rfc/` (if needed)
   - Generate each relevant documentation file
   - Populate with project-specific content

6. **Template Placeholders**:
   Replace these in templates:
   - `{{PROJECT_NAME}}` - From git repo name or directory name
   - `{{DATE}}` - Current date (YYYY-MM-DD format)
   - `{{TECH_STACK}}` - Detected technologies
   - `{{DESCRIPTION}}` - Brief project description from README or git
   - `{{CONTEXT}}` - Gathered context from codebase analysis

7. **Report Results**:
   - List all documentation files created
   - Show what was skipped (already exists)
   - Provide next steps

## Context Detection Examples

### Technology Stack
```bash
# Check for language/framework
!`find . -name "package.json" -o -name "pyproject.toml" -o -name "go.mod" -o -name "Cargo.toml" | head -5`

# Check for database
!`find . -name "*models.py" -o -name "*schema.prisma" -o -name "*entity.ts" | head -5`

# Check for infrastructure
!`find . -name "Dockerfile" -o -name "docker-compose.yml" -o -name "*.k8s.yaml" | head -5`
```

### Project Information
```bash
# Get project name
!`basename $(git rev-parse --show-toplevel 2>/dev/null || pwd)`

# Get project description
!`head -20 README.md 2>/dev/null || echo ""`
```

## Usage

Basic initialization (auto-detect everything):
```
/docs:init
```

With additional context:
```
/docs:init for Python FastAPI microservice
/docs:init for Next.js SaaS application
/docs:init for React component library
```

## Template Locations

Templates are loaded from `commands/docs/templates/`:

| Document Type | Template File |
|--------------|---------------|
| Architecture | `architecture.md` |
| Onboarding | `onboarding.md` |
| ADR (first) | `adr/nygard.md` |
| Data Model | `data-model.md` |
| Deployment | `deployment.md` |
| Security | `security.md` |
| Contributing | `contributing.md` |

## Important Notes

- **Zero-config**: Works without any configuration file
- **Smart detection**: Only generates relevant documentation
- **Safe**: Always asks before overwriting existing files
- **Customizable**: User context in command is used to enhance generation
- **Git-aware**: Uses git information when available
- **Incremental**: Can be run multiple times safely

## Example Output

```
Documentation Initialization Complete ✓

Created:
  ✓ docs/architecture.md - System architecture overview
  ✓ docs/onboarding.md - Developer onboarding guide
  ✓ docs/adr/0001-record-architecture-decisions.md - Meta-ADR
  ✓ docs/data-model.md - Database schema (SQLAlchemy detected)
  ✓ docs/deployment.md - Deployment guide (Docker detected)

Skipped (already exists):
  ⊘ docs/contributing.md

Next Steps:
  1. Review and customize generated documentation
  2. Run /docs:diagram er to generate ER diagram
  3. Run /docs:diagram arch to generate architecture diagram
  4. Create ADRs for key decisions: /docs:adr "Decision Title"
```

## When to Run

Run this command when:
- Starting a new project
- Adding documentation to an existing project
- Reorganizing project documentation
- Onboarding new team members

**Note**: You can run this command multiple times. It will only create missing files and ask before overwriting existing ones.
