usecix 1.0.6

Git-anchored cloud-first code index + MCP for Claude, Codex, and Gemini

cix

Git moves code. cix understands code. AI coding tools use cix to make safer changes.

cix is a code-intelligence layer that sits between Git and AI coding tools (Claude Code, Codex, Gemini). It indexes your committed source by Git commit and exposes it to your AI client as a set of structured tools — symbol search, navigation, schema lookup, impact analysis, and structured edits — so the assistant works from what your repository actually contains instead of guessing.

Why

AI coding tools are strong at writing code in isolation and weak at understanding your repository. They re-read files they have already seen, reinvent helpers that already exist, import modules that were deprecated, or rename a function and miss half of its callers. cix gives the assistant a precise, current answer to "what does this repository mean right now?" — so it writes code that fits.

Install

pip install usecix

The heavy indexing runs in the cix cloud, not on your machine; the local package is a thin client that connects over HTTPS.

Quick start

# 1. Connect this machine to your cix account (opens a browser)
cix login

# 2. Register cix with your AI clients (Claude Code, Codex, Gemini)
cix install --client all

# 3. Restart your client so it picks up the cix tools

# 4. In a project you want indexed
cd ~/path/to/your/project
cix index

Then open your AI client in that project and start working — it will use the cix tools to search, read by symbol, check schemas, and assess impact before editing.

Commands

cix installs a single cix dispatcher; each subcommand is also available as cix-<command> (for example, cix-index).

Command	What it does
cix login	Authenticate and fetch credentials
cix install	Install cix integrations (Claude, Codex, Gemini)
cix uninstall	Remove cix integrations
cix index	Build / update the index for the current project
cix mcp	Run the cix MCP server (stdio)
cix serve	Run the cix MCP server (remote SSE)
cix doctor	Diagnose your cix install and project setup
cix config	View / update per-project settings

Run cix <command> --help for details on any command.

Requirements

• Python 3.11+
• Git — cix indexes committed source and tracks freshness by commit.
• A GitHub-hosted repository for the project you want indexed.
• A supported AI client — Claude Code, Codex CLI, and/or Gemini CLI.
• A cix account — cix login walks you through it.
