github-codebase-search

Semantic search for public GitHub repositories powered by MorphLLM — an RL-trained subagent that runs parallel grep+read calls against the GitHub API to answer natural language questions about code. No cloning required.

Requires MORPH_API_KEY environment variable.

When to Use

• Understanding how a library or framework works internally (e.g., "how does Next.js resolve middleware?")
• Investigating upstream bugs or behavior in open-source dependencies
• Learning from reference implementations in well-known repos
• Tracing code paths in a repo you haven't cloned locally
• Exploring how an OSS project is structured or architected
