What It Does

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.

How CodeWeaver Stacks Up

Quick Reference Matrix

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

🚀 Getting Started

Quick Install

Using the CLI with uv:

# Add CodeWeaver to your project
uv add code-weaver

# Initialize with a profile (recommended uses Voyage AI)
cw init --profile recommended

# Verify setup
cw doctor

# Start the background daemon
cw start

📝 Note: cw init supports different Profiles:

• recommended: High-precision search (Voyage AI + Qdrant)
• quickstart: 100% local, private, and free (FastEmbed + Local Qdrant)

Want full offline? See the Local-Only Guide.

💭 Philosophy: Context is Oxygen

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.
