Search GitHub intelligently to find specs, reference implementations, library adopters, and config patterns. Use when research means locating code, repos, or examples on GitHub — pick the right surface (REST/web search vs GraphQL vs code search), the right qualifiers, and the right tool (gh CLI or mcp__github__*), then rank and verify results. Covers rate limits, the 1,000-result cap, and a goal->tool decision guide.
