CodeWeaver gives Claude and other AI agents precise context from your codebase. Not keyword grep. Not whole-file dumps. Actual structural understanding through hybrid semantic search.
CodeWeaver is Professional Context Infrastructure. With 100% Dependency Injection (DI) and a Pydantic-driven configuration system, it provides the reliability and extensibility required for industrial-grade AI deployments.
Example:
Without CodeWeaver:
Claude: "Let me search for 'auth'... here are 50 files mentioning authentication"
Result: Generic code, wrong context, wasted tokens
With CodeWeaver:
You: "Where do we validate OAuth tokens?"
Claude gets: The exact 3 functions across 2 files, with surrounding context
Result: Precise answers, focused context, 60-80% token reduction
CodeWeaver is no longer in alpha!
Early Release (0.x): CodeWeaver is in active development. APIs may change between minor versions. It's very well-tested but still in 'it works on my machine' territory. Use it, break it, help shape it.
| Feature | CodeWeaver | Legacy Search Tools |
|---|---|---|
| Search Type | Hybrid (Semantic + AST + Keyword) | Keyword Only |
| Context Quality | Exquisite / High-Precision | Noisy / Irrelevant |
| Extensibility | DI-Driven (Zero-Code Provider Swap) | Hardcoded |
| Reliability | Resilient (Automatic Local Fallback) | Fails on API Timeout |
| Token Usage | Optimized (60–80% Reduction) | Wasted on Noise |

AI agents face too much irrelevant context, causing token waste, missed patterns, and hallucinations. CodeWeaver addresses this with one focused capability: structural + semantic code understanding that you control.
- Curation over Collection: Give agents exactly what they need, nothing more.
- Privacy-First: Your code stays local if you want it to.
- Infrastructure over Tooling: Built to be the reliable foundation for your AI stack.
