## AI Agent — Built-in Skills System

We've launched a built-in skills system with 16 pre-configured skills. The AI automatically matches and activates the right skill based on conversation context:

**Git Operations**
- Commit history analysis — view project evolution, search commits, visualize branch graphs
- Code change analysis — compare diffs, summarize changes, trace code authorship
- Branch management — list branches, check merge status, analyze sync state

**Code Quality**
- Code review — professional review covering security, performance, and best practices
- Code explainer — clarify complex code in plain language

**Project Management**
- Repository management — browse, create, and configure project repos
- Issue management — full workflow with triage, labels, and priority assessment
- Board management — organize kanban boards, manage cards, track progress
- Member management — view team structure, manage roles and permissions

**Developer Productivity**
- PR summary — auto-generate clear and concise PR descriptions
- Issue triage — intelligently classify issue type, priority, and component
- Documentation generator — create README, API docs, and inline docs
- Test generator — write well-structured unit tests
- Commit message generator — auto-generate conventional commit messages

**Utility**
- HTTP requester — API testing and debugging

All built-in skills are available to every project by default. Use `@skill-name` or natural language to activate them. Project admins can customize or override them.
