README

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 - 418 rules sourced from official specs, academic research, and real-world breakage patterns. Auto-fix included.

Want to try it first? Open the playground - paste any agent config, see diagnostics instantly. No install, runs in your browser.
