When you need library or framework documentation, check in this order:

1. If Context7 MCP tools (`mcp__context7__*`) are available in your environment, use them:
   - Resolve library ID: `mcp__context7__resolve-library-id` with `libraryName`
   - Fetch docs: `mcp__context7__get-library-docs` with `context7CompatibleLibraryId` and `topic`

2. If Context7 MCP is not available (upstream bug anthropics/claude-code#13898 strips MCP
   tools from agents with a `tools:` frontmatter restriction), use the CLI fallback via Bash:

   Step 1 — Resolve library ID:
   ```bash
   npx --yes ctx7@latest library <name> "<query>"
   ```
   Step 2 — Fetch documentation:
   ```bash
   npx --yes ctx7@latest docs <libraryId> "<query>"
   ```

Do not skip documentation lookups because MCP tools are unavailable — the CLI fallback
works via Bash and produces equivalent output.
