Mobile Release

Mobile Release

Perform a mobile release from dev, with an explicit release-mode decision before the bump.

The skill must recommend one of these modes, explain why, ask the user to confirm, and then write apps/mobile/release-plan.json before running the bump:

• store: normal App Store / Google Play release
• ota: OTA-only publish, no store builds

Do not recommend or write any other mode. The current implementation only supports store and ota.

The CI release flow is file-driven:

• apps/mobile/release-plan.json is the editable plan on dev
• pnpm bump runs apps/mobile/scripts/apply-release-config.ts
• that script writes apps/mobile/release.json for the new version and resets the plan back to a safe default
• GitHub Actions reads apps/mobile/release.json after merge to decide which pipelines to trigger

Pre-flight checks

1. Confirm the current branch is dev. If not, abort with a warning.
2. Run git pull --rebase in the repo root.
3. Read:
   • apps/mobile/package.json
   • apps/mobile/release-plan.json
   • .github/workflows/tag.yml
   • .github/workflows/publish-ota.yml

Step 1: Gather changes since last release

1. Find the last mobile tag:

   git tag --sort=-creatordate | grep -E '^mobile[@/]' | head -1
   

2. If no tag exists, fall back to the last release commit subject:

   git log --format="%H %s" | grep -Ei "^[a-f0-9]* release\\(mobile\\): release v" | head -1 | awk '{print $1}'
   

3. Collect commits since that point:

   git log <last-tag-or-commit>..HEAD --oneline --no-merges
   

4. Collect changed files:

   git diff --name-only <last-tag-or-commit>..HEAD
   

5. Categorize commits into:
   • Shiny new things
   • Improvements
   • No longer broken
   • Thanks

Step 2: Recommend a release mode

Recommend store when:

• any native or binary-affecting paths changed, for example:
  • apps/mobile/ios/**
  • apps/mobile/android/**
  • apps/mobile/native/**
  • apps/mobile/package.json
  • apps/mobile/app.config.ts
  • apps/mobile/app.config.base.ts
  • apps/mobile/eas.json
  • apps/mobile/ios/Folo/Info.plist
  • .github/workflows/build-ios.yml
  • .github/workflows/build-android.yml
• Expo / React Native / native dependency changes require a new binary
• permissions, entitlements, icons, splash, Firebase config, or build configuration changed

Recommend ota when:

• changes are limited to JS/TS/assets that the current binary can already run
• no native or runtime-affecting paths changed
• the goal is to ship without store review

Determine the target runtime

If recommending ota, derive the target runtime from the store binaries that users currently have installed, not from the new release version, latest mobile tag, or latest OTA release.

1. Check the public store versions first:

   curl --fail --silent --show-error https://ota.folo.is/versions | jq '.store.mobile'
   

2. Cross-check the store runtime model in apps/mobile/app.config.base.ts. Today the mobile runtime defaults to the binary package version unless OTA_RUNTIME_VERSION is explicitly set during an OTA export.
3. Use the current App Store / Google Play binary version as the OTA runtimeVersion. Example: if the stores still show 0.5.0, an OTA release for 0.5.4 must use "runtimeVersion": "0.5.0" so existing store users can receive it.
4. If iOS and Android store versions differ, or if the target installed runtime is not clear, stop and ask the user. The release plan supports only one OTA runtimeVersion; do not guess or silently pick the newest version.

Never choose the previous OTA release version just because it is the latest working manifest. A runtime mismatch publishes valid assets that only newer binaries can see, leaving current store users stuck on the older OTA.

If you cannot determine the runtime confidently, stop and ask the user to confirm it.

Confirmation gate

Present:

• the recommended mode
• rationale based on changed files and commits
• for ota, the proposed runtimeVersion
• for ota, the proposed channel

Wait for explicit user confirmation before continuing.

Step 3: Write the release plan file

Update apps/mobile/release-plan.json to match the confirmed mode.

Examples:

Store release

{
  "mode": "store",
  "runtimeVersion": null,
  "channel": null
}

OTA release

{
  "mode": "ota",
  "runtimeVersion": "0.4.1",
  "channel": "production"
}

Step 4: Update changelog

1. Read apps/mobile/changelog/next.md.
2. Present the categorized changes and draft changelog content.
3. Wait for user confirmation or edits before writing.
4. Write the final content to apps/mobile/changelog/next.md.

Step 5: Commit pre-bump files before bump

nbump requires a clean working tree.

1. Stage:

   git add apps/mobile/changelog/next.md apps/mobile/release-plan.json
   

2. Commit:

   git commit -m "docs(mobile): prepare release metadata"
   

3. If nothing changed, continue.

Step 6: Execute bump

1. Verify the working tree is clean:

   git status --short
   

2. Run:

   cd apps/mobile && pnpm bump
   

3. pnpm bump will:
   • apply changelog
   • bump package.json
   • update ios/Folo/Info.plist
   • run tsx scripts/apply-release-config.ts ${NEW_VERSION}
   • write apps/mobile/release.json
   • reset apps/mobile/release-plan.json back to the safe default store
   • create the release branch
   • push the branch
   • open a PR to mobile-main

Step 7: Verify and report

1. Confirm the PR was created successfully.
2. Read apps/mobile/release.json on the release branch and report:
   • new version
   • final release mode
   • runtimeVersion and channel if present
   • PR URL
3. Summarize expected post-merge automation:

mode=store

• create mobile tag
• trigger preview Android build
• trigger production Android build
• trigger production iOS build
• no OTA publish

mode=ota

• create mobile tag
• trigger OTA publish only
• no store builds

Do not require live OTA manifest verification during release PR preparation. The user manually merges the PR later, so the OTA publish happens after this workflow finishes and there may be a time gap before the Worker syncs. If the user later asks to check the rollout, verify the workflow run, GitHub Release assets, and /manifest at that time.
