- Frontmatter: 20-30 lines (JSON)
- Markdown content: 470-480 lines (description, examples, implementation notes)

## Naming Conventions

### Skill Names
- Format: `kebab-case` (hyphens only)
- Prefix: `ck-` (ClaudeKit namespace)
- Examples: `ck-code-review`, `ck-frontend-development`, `ck-ai-multimodal`

### Categories
- `ck-core` — Core workflow skills
- `ck-development` — Language/framework skills
- `ck-specialized` — Domain expertise skills
- `ck-guards` — Security and quality guards
- `ck-commands` — CLI commands
- `ck-agents` — Manager surfaces/agents

### Files
- Skills: `skills/{skill-name}/SKILL.md`
- Templates: `templates/SKILL.md`
- Docs: `docs/{topic}.md`

## Dependencies & Integrations

### External
- **Antigravity IDE (Gemini CLI)** v1.0+ — Required runtime
- No ClaudeKit IDE, no Task tool, no Hook system

### Internal
- Most skills are independent
- Utilities reused: `ck-help`, `ck-research`, `ck-git`
- Guard skills operate transparently (no direct dependencies)
- Commands invoke other skills as needed

## Installation & Distribution

### Package Contents
- 76 skill SKILL.md files
- 1 SKILL.md template for contributors
- Installation scripts (bash, PowerShell)
- skills_index.json registry
- Comprehensive documentation

### Installation
```bash
# Global (all projects)
./install.sh --global
# → ~/.gemini/antigravity/skills/

# Workspace (current project)
./install.sh --workspace
# → ./.agent/skills/

# Windows
.\install.ps1
```

## Documentation Structure

```
docs/
├── project-overview-pdr.md          # Project PDR & vision
├── codebase-summary.md              # Code structure (this file)
├── migration-guide-from-claudekit.md # How to migrate from old CK
├── project-changelog.md             # Version history
└── skill-categories-guide.md        # Detailed category reference
```

## Performance & Scalability

### Latency
- Skill invocation: < 100ms (excluding LLM)
- Frontmatter parsing: < 50ms per skill
- Full workflow: LLM-dependent (typically 2-10 minutes)

### Scalability
- Designed for teams of any size
- Handles projects from starter to enterprise
- Can be extended with custom skills

## Security & Privacy

### Data Handling
- Privacy guard prevents secret exposure
- Code stays local (not sent to external services)
- No telemetry or usage tracking
- Open-source (MIT license)

### Code Review
- Zero hardcoded credentials
- No shell execution (Antigravity IDE safe)
- Security-focused guard skills included

## Known Limitations

1. **No Task tool**: Skills invoke sequentially via user direction
2. **No Hooks**: Hard-gates replace hook system
3. **No Slash commands**: Semantic triggering instead
4. **Single IDE**: Requires Antigravity IDE v1.0+
5. **No real-time sync**: Docs/code are local files

## Future Enhancements (Out of Scope v1.0)

- Web dashboard for workflow visualization
- Real-time team collaboration
- GitHub/GitLab deep integration
- Custom skill plugins
- AI-powered code generation (Claude API)
- Multi-language support
