Codeweaver

Gives Claude structural code search across 166 languages using hybrid semantic + AST-aware indexing. Exposes find_code operations that return precise function and class definitions instead of whole-file dumps or noisy keyword matches. Built on dependency injection with automatic fallback from cloud embeddings (Voyage AI) to local FastEmbed when offline. You'd reach for this when you want agents to pull exact context from large codebases without burning tokens on irrelevant results. Includes a CLI daemon (cw start) for live file watching, Qdrant for vector storage, and reciprocal rank fusion to merge sparse and dense search results. Works completely airgapped if you initialize with the quickstart profile.
