ccc — a Claude Code skill from cocoindex-io/cocoindex-code

Features

  • ✓**Semantic Code Search**: Find relevant code using natural language queries when grep doesn't work well, and save tokens immediately.
  • ✓**Ultra Performant**: ⚡ Built on top of ultra performant [Rust indexing engine](https://github.com/cocoindex-io/cocoindex). Only re-indexes changed files for fast updates.
  • ✓**Multi-Language Support**: Python, JavaScript/TypeScript, Rust, Go, Java, C/C++, C#, SQL, Shell, and more.
  • ✓**Embedded**: Portable and just works, no database setup required!
  • ✓**Flexible Embeddings**: Local SentenceTransformers via the `[full]` extra (free, no API key!) or 100+ cloud providers via LiteLLM.

Installation Guide

Using pipx:
bash
pipx install 'cocoindex-code[full]'          # batteries included (local embeddings)
pipx upgrade cocoindex-code                  # upgrade

Using uv:

bash
uv tool install --upgrade 'cocoindex-code[full]' --prerelease explicit --with "cocoindex>=1.0.0a24"

Two install styles — they mirror the Docker image variants of the same names:

  • cocoindex-codefull] — batteries-included. Pulls in sentence-transformers so local embeddings (no API key required) work out of the box. The ccc init interactive prompt defaults to [Snowflake/snowflake-arctic-embed-xs.

  • cocoindex-code (slim) — LiteLLM-only; requires a cloud embedding provider and API key. Use when you don't want the local-embedding deps (~1 GB of torch + transformers).

    • Next, set up your [coding agent integration](#coding-agent-integration) — or jump to [Manual CLI Usage](#manual-cli-usage) if you prefer direct control.
