# README Updater Skill

Keep your README current with project changes.

## When I Activate

- ✅ New features added
- ✅ Project structure changes
- ✅ Dependencies added/removed
- ✅ Setup instructions change
- ✅ User mentions README or documentation
- ✅ Configuration files modified

## What I Update

### README Sections

**Installation:**
- New dependencies
- Setup steps
- Prerequisites
- Environment variables

**Features:**
- New capabilities
- Functionality changes
- Feature deprecation

**Usage:**
- API changes
- New examples
- Updated screenshots

**Configuration:**
- New options
- Environment variables
- Config file changes

## Examples

### New Feature Addition

```bash
# You add authentication:
git diff
# + auth.service.ts
# + login.component.tsx
# + JWT middleware

# I suggest README update:
## Features
- ✨ User authentication with JWT  # NEW
- 🔐 Role-based access control    # NEW
- User management
- Dashboard
```

### New Dependency

```bash
# You add: npm install stripe

# I suggest:
## Installation

```bash
npm install
npm install stripe  # Added for payment processing
```

## Environment Variables
```bash
STRIPE_SECRET_KEY=your_stripe_key  # Required for payments
```
```

### Setup Instructions

```bash
# You modify docker-compose.yml

# I update README:
## Development Setup

```bash
# 1. Clone repository
git clone [url]

# 2. Install dependencies
npm install

# 3. Start services (UPDATED)
docker-compose up -d  # Now includes Redis cache

# 4. Run migrations
npm run migrate
```
```

## Detection Logic

### Change Analysis

I detect these changes automatically:
- **package.json** → Update dependencies section
- **New routes** → Update API documentation
- **.env.example** → Update environment variables
- **docker-compose.yml** → Update setup instructions
- **New features** → Update features list

### Section Mapping

```yaml
Code Change → README Section:
  - New API endpoint → Usage / API Reference
  - New dependency → Installation
  - New env var → Configuration
  - New feature → Features list
  - Architecture change → Architecture section
```

## Intelligent Updates

### Keep Structure

I maintain your README structure:
- Preserve emoji style
- Keep formatting consistent
- Maintain tone and voice
- Respect existing organization

### Add Missing Sections

```markdown
# Suggested additions:

## Prerequisites
- Node.js 18+
- Docker (for development)
- PostgreSQL 14+

## Environment Variables
```bash
DATABASE_URL=postgresql://localhost/mydb
API_KEY=your_api_key
```

## Testing
```bash
npm test
```
```

### Update Examples

```markdown
# Before:
```javascript
const result = api.getUsers();
```

# After (API changed):
```javascript
const result = await api.getUsers({ page: 1, limit: 10 });
```
```

## Version Compatibility

I track version-specific documentation:

```markdown
## Requirements

- Node.js 18+ (updated from 16+)
- TypeScript 5.0+ (new requirement)
- React 18+ (unchanged)
```

## Changelog Integration

I can sync with CHANGELOG.md:

```markdown
## Recent Changes

See [CHANGELOG.md](CHANGELOG.md) for detailed version history.

### Latest (v2.1.0)
- ✨ Added user authentication
- 🔧 Fixed memory leak in data processing
- 📝 Updated API documentation
```

## Screenshot Management

```markdown
# I suggest when UI changes:
## Screenshots

![Dashboard](screenshots/dashboard.png)
*Updated: 2025-10-24 - New authentication panel*

![User Profile](screenshots/profile.png)
*New feature - user profile management*
```

## Relationship with @docs-writer

**Me (Skill):** Keep README current with code changes
**@docs-writer (Sub-Agent):** Comprehensive documentation strategy

### Workflow
1. I detect changes
2. I suggest README updates
3. For full docs → Invoke **@docs-writer** sub-agent
4. Sub-agent creates complete documentation

## Sandboxing Compatibility

**Works without sandboxing:** ✅ Yes
**Works with sandboxing:** ✅ Yes

- **Filesystem**: Writes to README.md
- **Network**: None required
- **Configuration**: None required

## Best Practices

1. **Keep it current** - Update README with every feature
2. **Be specific** - Include version numbers, prerequisites
3. **Add examples** - Show actual usage, not just API
4. **Include troubleshooting** - Common issues and solutions
5. **Badge status** - Keep build/coverage badges current

## Integration

### With /docs-gen Command

```bash
/docs-gen --format markdown

# Generates:
# 1. README.md (via me)
# 2. Full documentation site (via @docs-writer)
# 3. API reference (via api-documenter)
```

### With CI/CD

```yaml
# .github/workflows/docs.yml
- name: Update README
  run: |
    # Skill suggests updates based on changes
    # Review and commit
```

## Customization

Add company-specific README standards:

```bash
cp -r ~/.claude/skills/documentation/readme-updater \
      ~/.claude/skills/documentation/company-readme-updater

# Edit to add:
# - Company README template
# - Required sections
# - Badge standards
```
