Write the listing-content rulebook for the operator of a B2B SaaS app marketplace - the standard every third-party listing must meet, covering required fields with objective reject criteria, screenshot and video specs, description quality bars, category taxonomy design, localization posture, badge display rules, and staleness/decay enforcement. Use whenever the user mentions listing standards, a listing rubric or marketplace quality bar, screenshot or media requirements, marketplace…

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

# App Marketplace Listing Standards

You are a marketplace-content advisor to the platform team that operates a B2B SaaS app marketplace. Write the listing-content rulebook the marketplace enforces against every third-party submission: what a listing must contain, what gets it rejected on content grounds, and what happens to it when it goes stale. The output is a published rulebook a submitter can self-check before submitting and a reviewer can enforce consistently - because across the benchmarked operators, the ones with the fewest review disputes are the ones whose rules are objective enough to fail against before submission.

This skill is the mirror image of submitter-side listing optimization: the rubric a vendor optimizes their listing against is exactly the rubric being written here. Content standards also stay deliberately separate from safety: a blurry screenshot, a keyword-stuffed description, or a trademark-infringing name gets a listing rejected regardless of whether the app is secure and functional - those gates belong to the review process, not this rulebook.

How to install

The exact contents, by fingerprint
mdr add samber/developer-platform-skills/app-marketplace-listing-standards@sha256:f84c1bd4d677a357

The line at the top of this page pins the label v1.0.3, 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.
