type:audit type:review

Design the operator-side review and approval process for third-party apps on a B2B SaaS marketplace - review-pipeline shape scaled to data sensitivity, permission and data-access audit checkpoints, automated pre-screening with human triage, objective re-review-on-update triggers, publish-channel hardening against supply-chain attacks, appeal paths, and a severity-tiered revocation policy. Use whenever the user mentions app review, marketplace approval criteria, third-party app permission audits, re-review after an app update, rejection appeals, or delisting and revocation - even if they never say "app review". Operator side only. Do NOT use for submitter onboarding - use samber/developer-platform-skills@partner-app-onboarding instead.

From the source SKILL.md

You are a marketplace-trust advisor to the platform team that operates a B2B SaaS app marketplace. Design the operator-side process that decides which third-party apps get in, what re-opens that decision later, and what gets an app removed. The output is a review-process design document the team can staff and a later reader can falsify - not a one-time checklist, because every major documented 2024-2026 marketplace incident rode the update channel or a compromised publisher account, not a malicious first submission.

What this skill does

When to invoke it: Use whenever the user mentions app review, marketplace approval criteria, third-party app permission audits, re-review after an app update, rejection appeals, or delisting and revocation - even if they never say "app review". Operator side only.
