| File | Contents |
|------|----------|
| `references/python.md` | Python ADK API quick reference — agents, tools, auth, orchestration, callbacks, plugins, state, artifacts, context caching/compaction, session rewind |
| `references/docs-index.md` | ADK docs index (synced from llms.txt) — titles and URLs for fetching ADK documentation pages. If missing, fetch `https://google.github.io/adk-docs/llms.txt` using your agent's web fetch tool or `curl`. |
Read `references/python.md` for the full API quick reference.
> **Creating a new agent project?** Use `/adk-scaffold` instead — this skill is for writing code in existing projects.
