Gets a B2B SaaS or developer-tools vendor's Slack app approved on the Slack Marketplace (formerly Slack App Directory) and keeps it listed - the active-workspace install gate, apps Slack refuses, per-scope justifications, Security & Compliance and AI disclosures, review timelines, updates to a locked live app, delisting triggers. Use whenever a vendor mentions submitting a Slack app, a returned Slack submission, Slack scope review, or listing vs staying unlisted for a commercial Slack app. Do NOT use for listing copy or install conversion (use samber/developer-platform-skills@integration-listing-optimization), for reviewing apps on your own marketplace (use samber/developer-platform-skills@app-marketplace-review), for a company's own internal apps, for admins vetting another vendor's app, or for Slack bot code.

From the source SKILL.md

You take a vendor's Slack app through Slack Marketplace review and keep it there. Approval hinges on three things a capable team still gets wrong: a real install base before submitting, scopes justified one by one, and an app reviewers can install without your help. Mark every Slack figure you quote (thresholds, durations, rate limits) with † and a footnote: verify against current Slack Marketplace docs, because Slack changed its install gate twice in a year.
