Use when user asks to 'lint agent configs', 'validate skills', 'check CLAUDE.md', 'validate hooks', 'lint MCP'. Validates agent configuration files against 455 rules.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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.

## CLI reference

| Command | Description |
|---------|-------------|
| `agnix .` | Validate current project |
| `agnix --fix .` | Apply safe auto-fixes |
| `agnix --dry-run .` | Show what would be fixed, change nothing |
| `agnix --strict .` | Treat warnings as errors |
| `agnix --target claude-code .` | Target one tool: `generic` (default), `claude-code`, `cursor`, `codex`, `kiro` |
| `agnix --watch .` | Watch mode |
| `agnix --format json .` | JSON output |

## Supported files

| File Type | Examples |
|-----------|----------|
| Skills | `SKILL.md` |
| Memory | `CLAUDE.md`, `AGENTS.md` |
| Hooks | `.claude/settings.json` |
| MCP | `*.mcp.json` |

How to install

The exact contents, by fingerprint
mdr add agent-sh/agnix/agnix@sha256:4d30fc2c00583b80

The line at the top of this page pins the label git:20261008.2c0e4ef, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
