# Implement Claude Extensions

Use this umbrella skill to choose the correct extension type and route implementation to the appropriate component skill.

## Comparison

| Extension Type | Best For                           | Primary Artifacts                | Component Skill                      |
| -------------- | ---------------------------------- | -------------------------------- | ------------------------------------ |
| Hooks          | Event-driven automation/guardrails | `hooks/hooks.json`, hook scripts | `../implement-hooks/SKILL.md`        |
| Agent Skills   | Reusable task playbooks            | `skills/<name>/SKILL.md`         | `../implement-agent-skills/SKILL.md` |
| Sub-Agents     | Specialized delegated roles        | `agents/*.md`                    | `../implement-sub-agents/SKILL.md`   |
| Agent Teams    | Coordinated multi-agent execution  | team config + coordination docs  | `../implement-agent-teams/SKILL.md`  |
| Plugins        | Packaging/distribution + wiring    | `.claude-plugin/plugin.json`     | `../implement-plugin/SKILL.md`       |

## Workflow

1. Identify outcome and constraints.
2. Use `references/when-to-use.md` to pick extension type(s).
3. Hand off implementation to component skill(s).
4. Apply shared lifecycle checks before verification.
