Malinois

Runs a passive, outside-in security check of a live web app and returns a letter grade (A–F), each issue in plain language with fix steps, and a report link. Use when the user asks whether their deployed app is safe, before launch, or after a redeploy to confirm a fix. It checks for publicly readable Supabase/Firebase data, secret keys (Stripe, OpenAI, Supabase service_role…) in client JavaScript, downloadable .env/.git files, source maps, permissive CORS and missing security headers. Do not use it for apps the user does not own or is not authorized to test, for localhost or private addresses, or to review source code — it only sees what the public URL serves. Behavior: sends ordinary GET requests like a browser (no login, exploitation or load testing); takes about 10–30 seconds; saves the result as a report page on malinois.app, linked in the response; secrets appear only masked. Each app can be checked at most 20 times per hour.

Returns the plain-language meaning and step-by-step fix for one Malinois finding. Use it while helping the user fix an issue reported by scan_app, or when they ask what a finding means. Pass the rule_id exactly as scan_app returned it. Read-only, no network, instant.
