Adds 26 methods for code analysis across 11 languages, built on tree-sitter parsing and optional vector embeddings. You get semantic search over natural language queries, JSCPD clone detection, impact analysis, and complexity hotspots. It integrates with Claude Desktop, Claude Code, Gemini CLI, and Codex, and handles multi-project setups through config. The batched indexing mode works around strict client timeouts, and there's a dedicated Lerna workspace graph exporter if you're in a monorepo. Benchmarks show 5.5x faster execution than native Claude tooling. Useful when you need cross-file reasoning or refactoring guidance that goes beyond grep and regex.
