upgrade-app

name	upgrade-app
description	Automates the process of upgrading the app version. Bumps versionCode and versionName in build.gradle.kts, updates the changelog, verifies the build, commits, pushes, and creates a GitHub release. Use when the user says "upgrade app", "release new version", or "bump version".

Upgrade App Workflow

This skill automates the end-to-end process of releasing a new version of the application.

Workflow Steps

1. Preparation

• Ensure the git working tree is clean (git status).
• Check gh auth status to ensure GitHub CLI is authenticated.

2. Research & Versioning

• Read app/build.gradle.kts to find the current versionCode and versionName.
• Suggest a new versionName (e.g., if current is 1.7.1, suggest 1.7.2).
• Increment versionCode by 1.

3. Update Files

• Update app/build.gradle.kts with the new version info.
• Fetch commits since the last tag:

  LAST_TAG=$(git describe --tags --abbrev=0)
  git log $LAST_TAG..HEAD --oneline
  

• Generate a concise changelog and write it to fastlane/metadata/android/en-US/changelogs/<new-versionCode>.txt.

4. User Confirmation

• MANDATORY: Present the generated changelog to the user.
• WAIT for the user to confirm or edit the changelog before proceeding.

5. Build Verification

• Run ./gradlew assembleDebug to verify the build.
• If it fails, stop and report errors.

6. Git & GitHub Operations (MUST BE SEQUENTIAL)

• To avoid race conditions and tagging the wrong commit, execute the commit and tagging sequentially in a single command block:

  git add app/build.gradle.kts fastlane/metadata/android/en-US/changelogs/<new-versionCode>.txt && \
  git commit -m "chore: bump version to <versionName> (<versionCode>)" && \
  git tag v<versionName> && \
  git push origin main && \
  git push origin v<versionName> && \
  gh release create v<versionName> --title "v<versionName>" --notes-file fastlane/metadata/android/en-US/changelogs/<new-versionCode>.txt
  

Guardrails

• Race Condition Prevention: Never separate git commit and git tag into different tool calls in the same turn without wait_for_previous: true.
• Validation: Always verify the build with ./gradlew assembleDebug before pushing.
• Confirmation: Always wait for user confirmation on the changelog.
• Format: Ensure the tag matches the vX.Y.Z format.
