dot

digraph release_prepare {
    rankdir=TB;
    node [shape=box];
    
    start [label="Start Preparation" shape=ellipse];
    gather [label="1. Gather Changes"];
    version [label="2. Determine Version"];

    start -> gather -> version -> notes;
    notes -> changelog -> env -> migration;
    migration -> checklist -> summary -> done;
}

Execution Steps

Step 1: Gather Changes

Collect all changes since last release:

bash

# Get last release tag
LAST_TAG=$(git describe --tags --abbrev=0 2>/dev/null || echo "")

# List commits since last release
if [ -n "$LAST_TAG" ]; then
    git log ${LAST_TAG}..HEAD --oneline --no-merges
else
    git log --oneline -20
fi

# List merged PRs
gh pr list --state merged --limit 20 --json number,title,labels

Categorize changes:

Features: New functionality
Fixes: Bug fixes
Improvements: Enhancements
Breaking: Breaking changes
Docs: Documentation updates
Chores: Maintenance/tooling

Step 2: Determine Version

Follow semantic versioning:

MAJOR.MINOR.PATCH

MAJOR: Breaking changes
MINOR: New features (backwards compatible)
PATCH: Bug fixes (backwards compatible)

Ask user:

Based on the changes, I recommend version [X.Y.Z].

Changes include:

[N] new features

[N] bug fixes

[N] breaking changes

Is this version correct, or would you like to specify?

Step 3: Generate Release Notes

Create release notes:

markdown

# Release Notes: v[X.Y.Z]

**Release Date**: [YYYY-MM-DD]
**Environment**: [staging/production]

## Highlights

[1-2 sentence summary of the most important changes]

## What's New

### Features
- **[Feature Name]**: [Brief description] (#123)
- **[Feature Name]**: [Brief description] (#124)

### Improvements
- [Improvement description] (#125)

### Bug Fixes
- Fixed [issue description] (#126)
- Fixed [issue description] (#127)

## Breaking Changes

[If any, describe migration steps]

## Dependencies

- Updated [package] from X to Y
- Added [new package] for [purpose]

## Contributors

- @username
- @username

## Full Changelog

[Link to compare: previous...current]

Step 4: Update CHANGELOG

Update CHANGELOG.md (if it exists) or docs/ai/CHANGELOG.md:

markdown

## [X.Y.Z] - YYYY-MM-DD

### Added
- Feature description (#123)

### Changed
- Change description (#124)

### Fixed
- Fix description (#125)

### Removed
- Removal description (#126)

Step 5: Verify Environment

Check target environment is ready:

bash

# For Vercel (web)
vercel env ls --environment production

# Check required env vars are set
REQUIRED_VARS=(
    "DATABASE_URL"
    "CLERK_SECRET_KEY"
    "NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY"
)

for var in "${REQUIRED_VARS[@]}"; do
    vercel env ls --environment production | grep -q "$var" && \
        echo "OK: $var" || echo "MISSING: $var"
done

For mobile (EAS):

bash

# Check EAS configuration
eas config --platform ios
eas config --platform android

# Verify credentials
eas credentials --platform ios
eas credentials --platform android

Step 6: Check Migrations

If database changes are included:

markdown

## Migration Check

### Pending Migrations
- [ ] `20250105_add_feature_table.sql`

### Migration Plan
1. Backup production database
2. Apply migration in staging first
3. Verify data integrity
4. Apply to production during low-traffic window

### Rollback Plan
```sql
-- Rollback script
DROP TABLE IF EXISTS new_table;
ALTER TABLE existing_table DROP COLUMN new_column;

Data Impact

Rows affected: ~[N]
Estimated duration: [X] seconds
Downtime required: No


### Step 7: Run Release Checklist

Use the release checklist from `docs/ai/checklists/release-checklist.md`:

```markdown
## Pre-Release Checklist

## Red Flags

| Rationalization | Correction |
|-----------------|------------|
| "Skip env verification, it worked before" | ALWAYS verify environment for each release |
| "No migrations, skip that section" | Document "no migrations" explicitly |
| "Changelog can be updated later" | Update changelog BEFORE deploying |
| "Just push to main, Vercel handles it" | Follow full preparation process |

## Integration

- **Input**: Version number (or auto-determine), target environment
- **References**: QA handoffs, merged PRs, git history
- **Output**: Release summary, changelog updates, release notes
- **Next**: `gmacko-release-deploy-web` or `gmacko-release-deploy-mobile`
