Playground
Paste any SKILL.md, Codex skill.yaml, Claude Code command, or OpenCode config — drop a URL, or pick a sample. The full static / semantic / adversarial pipeline runs in your browser session, free.
Without a key we run static rules only. Findings still cover ~70 percent of common issues.
Paste a SKILL.md and click Run audit to see findings here.
