## 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

# Suggested additions:

## Prerequisites
- Node.js 18+

Relationship with @docs-writer

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

Workflow

I detect changes
I suggest README updates
For full docs → Invoke @docs-writer sub-agent
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

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