Play Store Access: $ARGUMENTS

Read-only access layer for Google Play release state in Expo projects. Use it to answer whether the Android app is live, halted, draft, or in staged rollout on a Play track after EAS submission.

This skill MUST NOT promote tracks, change rollout percentages, create releases, or submit builds. EAS remains the submission path.

Invocation Contract

operation: setup
operation: production-status [track:production] [package:<android.package>]
operation: track-status track:<track> [package:<android.package>]
operation: resolve-package

Return a concise result with the package name, track, release name / versionCodes, status, userFraction when present, and any countryTargeting or in-app update priority fields present in the API response.

Configuration

Project-safe config can live in .lisa.config.json:

{
  "playStore": {
    "packageName": "com.example.app",
    "track": "production"
  }
}

Local credential config belongs in .lisa.config.local.json, which must stay gitignored:

{
  "playStore": {
    "serviceAccountKeyPath": "./google-play-service-account.json"
  }
}

Supported credential locations, in resolution order:

1. GOOGLE_PLAY_SERVICE_ACCOUNT_JSON containing the raw service-account JSON.
2. GOOGLE_PLAY_SERVICE_ACCOUNT_KEY_BASE64 containing base64 JSON.
3. .lisa.config.local.json playStore.serviceAccountKeyPath.
4. Darwin keychain item lisa-google-play account <packageName>.

Fail closed if no credential is available. Never prompt indefinitely and never fall back to Play Console UI scraping.

One-Time Setup Flow

For operation: setup:

1. Confirm the project is an Expo app by checking for app.json, app.config.json, app.config.js, or app.config.ts.

2. Resolve or ask the operator to provide the Android package name. Prefer .lisa.config.json playStore.packageName, then expo.android.package from app config.

3. In Google Cloud Console, create a service account dedicated to read-only Play release visibility and create a JSON key for it.

4. In Play Console, open Setup -> API access, link the Google Cloud project if needed, then grant the service-account email app access with read-level release visibility. Do not grant release-management write permissions for v1.

5. Store the key locally using one of the credential locations above. If using a path, add the path to .gitignore and record only the path in .lisa.config.local.json.

6. Record non-secret defaults in .lisa.config.json:

   jq '.playStore.packageName = "com.example.app" | .playStore.track = "production"' \
     .lisa.config.json > /tmp/lisa-config.json && mv /tmp/lisa-config.json .lisa.config.json
   

The key material itself must never be committed.

Resolve Package Name

Resolution order:

1. Explicit package:<value> argument.

2. .lisa.config.json playStore.packageName.

3. app.json / app.config.json expo.android.package.

4. app.config.ts / app.config.js by running Expo config export:

   npx expo config --json | jq -r '.android.package // empty'
   

If the package still cannot be resolved, fail with:

Error: Google Play package name is not configured. Set playStore.packageName in .lisa.config.json or pass package:<name>.

Read Track State

The androidpublisher API requires an edit even for track reads. Create the edit, list the track, then delete the edit. Do not commit the edit.

Interpretation:

• status: completed means the release is live on that track.
• status: inProgress means staged rollout; inspect userFraction.
• status: halted means rollout was stopped.
• status: draft means it is not live.
• Absence of a production release means the app has no watchable production-track release through the API.

Known limitation: androidpublisher exposes track/release state well, but pre-publication review state is coarse. The reliable watchable signal is whether the target version is live on the production track.

Error Handling

• 401 / token exchange failure: service-account key is invalid or expired.
• 403: service account is not invited to the Play Console app or lacks read access to releases.
• 404: package name is wrong, the app is not created in Play Console, or the service account has no access to that app.

In all cases, report the package name and credential source used, but never print private key material or the access token.
