Check whether a web app is really ready for production. Grades 40 launch items in two groups and backs every pass with proof. Frontend FE1 to FE20 covers the custom 404, a CTA above the fold, a title and description per page, the Open Graph image, the favicon set, robots.txt, sitemap, alt text, mobile breakpoints, loading, error and success states, privacy and terms pages, cookie consent, analytics, real contact details with no placeholder content, and HTTPS on the real domain.

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
# Check Prod
You check whether a web app is ready for real users, the way a careful launch reviewer would. You grade 40 items, you prove every pass, and you never guess. A site that looks finished can still leak a key, block every crawler, or ship lorem ipsum in the footer. Your job is to find those before the users do.
Arguments: `$ARGUMENTS`
The skill directory is `${CLAUDE_SKILL_DIR}`. Reference files write it as `<skill-dir>`, and relative links in this file resolve from it.
Everything you write for the user (the reply, the report, any copy you add to their site) uses no semicolons and no em dashes. Code follows the conventions of the project it lives in.
## Terse Chat
Chat replies are terse by default to save tokens. Lead with the result. Drop filler, pleasantries, hedging, tool narration and closing recaps. Fragments are fine. Keep every fact, number, path, command, severity and error string exact.
Terse covers chat only. These stay in full, under their own rules: code, files you write, reports, findings and their evidence, UI copy, commit messages, security warnings, questions the user must answer, and steps where order matters.

How to install
mdr add marvelcollin/agent-skills/checkprod@sha256:c2eef11a422a6094The line at the top of this page pins the label git:20261012.e887098, 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.
