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…
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
# Slack App Directory playbook 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. ## Rules the review enforces 1. Submit only with **10 or more active workspaces†** (used in the last 28 days, sandboxes excluded) and keep that count through the whole review: Slack blocks the submission below it. The suitability list pairs that count with 10 weekly active users†; the hard block is the workspace count. Pilot as an unlisted distributed app until then. 2. Request only scopes for features that exist today. Reviewers approve what they can test; a scope "for the roadmap" gets the submission returned. 3. Default to the bot token; user-token scopes pass only when the app must act as that user. …

How to install
mdr add samber/developer-platform-skills/slack-app-directory-playbook@sha256:6f0655cf0945b5ccThe line at the top of this page pins the label v1.0.2, 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.
