Preflight a SKILL.md before your agent runs it.
Paste an Agent Skill or workflow. This static check looks for obvious credential patterns, dangerous execution, missing human approval boundaries, duplicate-side-effect risk and unbounded retries. Everything runs in your browser.
Privacy: your pasted SKILL.md is processed locally by this app's browser logic. The app does not send pasted content to an API. Hosting may still receive ordinary page requests/access logs.
