ukulele-companion: Skill for Cursor

.cursor/skills/play-store-promote/SKILL.md

play-store-promote is a skill for Cursor from baijum/ukulele-companion. It costs 56 tokens per session (674 once invoked), scanned A, original, MIT.

A workflow for moving an Android release from Google Play's internal testing track to a closed testing track such as Alpha or App Hive Testing.

In plain words
What is it for?
Use it after a release has been uploaded to internal testing and the required Play Console service account access is configured.
Why use it?
It removes the need to manually repeat the promotion steps and makes the target track explicit.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

play-store-promote scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Play Store Promote

Promote a release from the internal testing track to one of the closed testing tracks using the Gradle Play Publisher (GPP) plugin.

Prerequisites

  • Release already uploaded to internal testing (via play-store-upload or android-release)
  • Service account key at app/play-service-account.json
  • Service account has "Release to testing tracks" permission in Play Console

Workflow

Step 1: Choose the target track

Ask the user which closed testing track to promote to:

Track Name in Play Console
Alpha Alpha
App Hive Testing App Hive Testing

Step 2: Promote the release

Promote to Alpha:

./gradlew promoteReleaseArtifact --from-track internal --promote-track alpha --release-status completed

Promote to App Hive Testing:

./gradlew promoteReleaseArtifact --from-track internal --promote-track "App Hive Testing" --release-status completed
  • Use block_until_ms: 60000 (promotion typically takes 10-30s).
  • The --from-track internal flag tells GPP to take the latest release from internal testing.
  • The --release-status completed flag makes the release immediately available to testers.

Step 3: Report result

After a successful promotion, provide:

Quick Reference

Task Command
Promote to Alpha ./gradlew promoteReleaseArtifact --from-track internal --promote-track alpha --release-status completed
Promote to App Hive Testing ./gradlew promoteReleaseArtifact --from-track internal --promote-track "App Hive Testing" --release-status completed
Promote to production ./gradlew promoteReleaseArtifact --from-track internal --promote-track production --release-status completed
Staged rollout to production ./gradlew promoteReleaseArtifact --from-track internal --promote-track production --release-status inProgress --user-fraction 0.1

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
