Phase I: Releases - Automated Release Management

Overview

Phase I implements automated release workflow with changelog generation, GitHub Releases creation, and binary artifact publishing using semantic versioning.

Status

• Status: Complete
• Priority: Low
• Duration: 1 hour (simplified from 2h estimate)
• Agent: DeploymentAgent

GitHub as OS Mapping

GitHub Releases → Software Distribution
- Changelog → Release Notes
- Semantic Versioning → Version Control
- Release Assets → Binary Distribution
- Tags → Version Markers

Goals and Objectives

Primary Goals

1. Implement automated release workflow
2. Generate changelog from conventional commits
3. Create GitHub Releases automatically
4. Publish release artifacts
5. Maintain CHANGELOG.md

Success Metrics

• Release creation time < 2 minutes
• Changelog generation accuracy 100%
• Zero failed releases
• Proper semantic versioning
• Assets attached correctly

Implementation Details

1. Release Workflow

File: .github/workflows/release.yml

Automated release triggered by version tag push.

name: Release

on:
  push:
    tags:
      - 'v*'

permissions:
  contents: write

jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0

      - uses: actions/setup-node@v4
        with:
          node-version: '20'

      - name: Install dependencies
        run: npm ci

      - name: Build
        run: npm run build

      - name: Generate changelog
        id: changelog
        run: |
          # Extract changelog for this version
          VERSION=${GITHUB_REF#refs/tags/v}
          CHANGELOG=$(git log $(git describe --tags --abbrev=0 HEAD^)..HEAD --pretty=format:"- %s" --no-merges)

          echo "changelog<<EOF" >> $GITHUB_OUTPUT
          echo "$CHANGELOG" >> $GITHUB_OUTPUT
          echo "EOF" >> $GITHUB_OUTPUT

      - name: Create GitHub Release
        uses: actions/create-release@v1
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
          tag_name: ${{ github.ref }}
          release_name: Release ${{ github.ref }}
          body: |
            ## What's Changed

            ${{ steps.changelog.outputs.changelog }}

            ## Installation

            ```bash
            npm install @miyabi/agent-sdk@${{ github.ref }}
            ```

            ## Docker Image

            ```bash
            docker pull ghcr.io/shunsukehayashi/miyabi-agent:${{ github.ref }}
            ```
          draft: false
          prerelease: false

      - name: Publish to NPM
        if: success()
        run: npm publish
        env:
          NODE_AUTH_TOKEN: ${{ secrets.NPM_TOKEN }}

      - name: Update CHANGELOG.md
        run: |
          VERSION=${GITHUB_REF#refs/tags/v}
          DATE=$(date +%Y-%m-%d)

          cat > CHANGELOG.tmp <<EOF
          # Changelog

          ## [$VERSION] - $DATE

          ${{ steps.changelog.outputs.changelog }}

          EOF

          cat CHANGELOG.md >> CHANGELOG.tmp
          mv CHANGELOG.tmp CHANGELOG.md

          git config user.name "github-actions[bot]"
          git config user.email "github-actions[bot]@users.noreply.github.com"
          git add CHANGELOG.md
          git commit -m "chore: update CHANGELOG for v$VERSION"
          git push

2. Changelog Generation

Automatic changelog from conventional commits:

Commit Types:

• feat: → Features
• fix: → Bug Fixes
• chore: → Maintenance
• docs: → Documentation
• test: → Testing
• refactor: → Refactoring
• perf: → Performance
• ci: → CI/CD

Example Changelog:

# Changelog

## [2.1.0] - 2025-10-08

### Features
- feat: Add dark mode toggle
- feat: Implement auto-save

### Bug Fixes
- fix: Resolve login redirect loop
- fix: Fix memory leak in dashboard

### Documentation
- docs: Update API documentation
- docs: Add troubleshooting guide

### Maintenance
- chore(deps): Update dependencies
- chore: Update CI workflow

3. Release Process

Step 1: Update Version

# Patch version (2.0.0 → 2.0.1)
npm version patch

# Minor version (2.0.0 → 2.1.0)
npm version minor

# Major version (2.0.0 → 3.0.0)
npm version major

Step 2: Push Tag

git push origin v2.1.0

Step 3: Automatic Actions

GitHub Actions automatically:

1. Generates changelog from commits
2. Creates GitHub Release
3. Publishes to NPM (if configured)
4. Builds Docker image (if configured)
5. Updates CHANGELOG.md
6. Notifies team

Completion Criteria and KPIs

Key Performance Indicators

Usage Examples

Create Patch Release

# 1. Update version
npm version patch  # 2.0.0 → 2.0.1

# 2. Push tag
git push origin v2.0.1

# 3. Automatic release created

Create Minor Release

# 1. Update version
npm version minor  # 2.0.0 → 2.1.0

# 2. Push tag
git push origin v2.1.0

# 3. Automatic release created with changelog

Create Major Release

# 1. Update version
npm version major  # 2.0.0 → 3.0.0

# 2. Push tag
git push origin v3.0.0

# 3. Breaking changes documented in release notes

Testing Methodology

Test Release Creation

# 1. Create test tag
git tag v2.0.1-test
git push origin v2.0.1-test

# 2. Check GitHub Actions
gh run list --workflow=release.yml

# 3. Verify release created
gh release view v2.0.1-test

# 4. Clean up test release
gh release delete v2.0.1-test
git tag -d v2.0.1-test
git push origin :refs/tags/v2.0.1-test

Troubleshooting Guide

Issue: Release Creation Failed

Solutions:

1. Check workflow syntax
2. Verify tag format (must start with 'v')
3. Ensure GITHUB_TOKEN has write permissions
4. Review workflow logs

Issue: Changelog Not Generated

Solutions:

1. Check conventional commit format
2. Verify git history available
3. Ensure previous tag exists
4. Review changelog generation script

Issue: NPM Publish Failed

Solutions:

1. Verify NPM_TOKEN in secrets
2. Check package.json version
3. Ensure package name available
4. Review npm publish logs
