  Lint agent configurations before they break your workflow

Built and maintained with a lot of agent tokens and hours. If it saves you time, sponsoring helps keep it going.

Catch broken agent configs before your AI tools silently ignore them.757 rules across Claude Code, Codex CLI, OpenCode, Cursor, Copilot, and more -validating CLAUDE.md, SKILL.md, hooks, MCP configs, and other agent files.

Why agnix?

Your skills don't trigger. Vercel's research found skills invoke at 0% without correct syntax. One wrong field and your skill is invisible.

"Almost right" is the worst outcome. 66% of developers cite it as their biggest AI frustration. Misconfigured agents produce exactly this.

Multi-tool stacks fail silently. Cursor + Claude Code + Copilot each want different formats. A config that works in one tool breaks in another.

Bad patterns get amplified. AI assistants don't ignore wrong configs - they learn from them.

agnix validates all of it - 757 rules sourced from official specs, academic research, and real-world breakage patterns. Auto-fix included.
