Passive pre-launch report card for a live URL of an app or site built with AI (Lovable, Bolt, Replit, Cursor, v0, Claude). Scores security (secret keys visible in the page JavaScript, Supabase service_role keys, open Supabase or Firebase tables with --owner-check, security headers, HTTPS, cookies), phone design at 375 px, Google and AI search, and speed, then writes a "fix this first" list. Use when the user asks "is my app safe to launch", "did I leak my API key", "is my Supabase open", or…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Launch Check

`scripts/launch_check.py` (Python standard library; Playwright optional) loads a live URL the way a visitor's browser
does, scans what it downloaded, runs the two bundled audits (`scripts/polish_audit.py` for phone design,
`scripts/geo_audit.py` for search) and prints one report card. Run the tool and explain what it found; do not judge
the site by reading it. Source (MIT): https://github.com/Ces107/agent-forge/tree/main/skills/launch-check

## When to Use This Skill

- The user asks whether an app or site is ready or safe to launch, or wants a pre-launch checklist.
- The user asks whether an API key (Stripe, OpenAI, Anthropic, AWS, Supabase service_role) leaked into the frontend.
- The user asks whether their Supabase or Firebase database can be read by anyone.
- Not for authenticated flows, API fuzzing or penetration testing.

## What This Skill Does

1. Finds Python 3.9+ (`python3 --version`, then `python --version`, then `py -3 --version` on Windows) as `<PY>`;
   `<DIR>` is the folder that holds this SKILL.md.
2. Runs `<PY> "<DIR>/scripts/launch_check.py" <url> --report launch-report.html`.

How to install

The exact contents, by fingerprint

mdr add davepoon/buildwithclaude/launch-check@sha256:59989f21e5b0bd92

The line at the top of this page pins the label git:20261023.7ab47fa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
