agnix

Lint agent configurations (Skills, Hooks, MCP, Memory, Plugins) before they break a workflow, across Claude Code, Codex CLI, OpenCode, Kiro, Cursor, GitHub Copilot and other tools.

Run

1. `agnix --version`. If it is missing, install with `npm install -g agnix` or `cargo install agnix-cli`. 2. `agnix .` (or the path the user named). 3. If the user asked for fixes: `agnix --fix .`, then run step 2 again to confirm what remains. Otherwise change no files; `agnix --dry-run .` previews the fixes.
