Agix

Agent Graph IndeX — a universal package manager for AI CLI tools.

---

Agix installs, updates, and versions skills, plugins, and agents across the AI CLIs you use (Claude Code, Codex, …) from a single Agentfile. Declare what your project needs, commit the manifest, and let Agix reconcile every CLI to match.

💡 Why?

Each AI CLI has its own way of loading extensions — .claude/, ~/.codex/, marketplace installs, hand-copied skill files. Sharing a setup with a teammate or reproducing it on a new machine means a lot of manual plumbing.

Agix treats your AI tooling like any other dependency stack:

• One manifest, many CLIs — the same Agentfile provisions Claude Code, Codex, and more from the same sources.
• Reproducible installs — an Agentfile.lock pins exact revisions, so a teammate running agix install gets the same state you have.
• Heterogeneous sources — pull from local paths, GitHub repos, plain git URLs, or a CLI's native marketplace, all through the same commands.
• Self-contained exports — package a full working setup (manifest + lock + vendored local sources) as a zip you can drop onto another machine.
