Release Notes Generator

Generate comprehensive release notes in 3 formats from git commits.

Workflow

1. Analyze git history since last release tag or specified version
2. Fetch PR details (titles, descriptions, labels) via

   gh api

3. Categorize changes into features, bug fixes, improvements, security, breaking changes
4. Generate 3 outputs: CHANGELOG.md section (technical), PR release body (semi-technical), Slack message (user-friendly)
5. Transform language from technical jargon to accessible messaging
6. Alert on migrations if database migrations are detected

Output Formats

1. CHANGELOG.md Section

Technical format for developers:

## [0.18.0] - 2025-12-08

### Objective
[1-2 sentence summary]

### New Features
#### [Feature Name] (#PR)
- **Description**: ...
- **Impact**: ...

### Bug Fixes
- **[Module]**: Description (#issue, [error-tracker] ISSUE-XX)

### Technical Improvements
#### Performance / UI/UX / Architecture
- [Description]

### Database Migrations
[If applicable]

### Statistics
- PRs: X
- Features: Y
- Bugs: Z

2. PR Release Body

Uses template from

.github/PULL_REQUEST_TEMPLATE/release.md

• Objective summary
• Features with specs links
• Bug fixes with error tracker references
• Improvements by category
• Migration instructions
• Deployment checklist

3. Slack Announcement

Product-focused format from

.github/COMMUNICATION_TEMPLATE/slack-release.md

• PR link included for traceability
• Non-technical language
• Focus on user impact (end-users, admins, stakeholders)
• Emojis for readability
• Statistics summary

Workflow Integration

This skill integrates with the release workflow:

1. Analyze commits: git log <last-tag>..HEAD
2. Determine version number (MAJOR.MINOR.PATCH)
3. Generate 3 outputs
4. Create PR develop -> main with "Release" label
5. Update CHANGELOG.md
6. After merge: create git tag
7. Generate Slack announcement

Tech-to-Product Transformation

The skill automatically transforms technical language:

Commit Categories

Commits are categorized by conventional commit prefix:

feat:

fix:

perf:

security:

refactor:

chore:

docs:

test:

style:

Console Output Format

When generating release notes, ALWAYS display a clear summary in the console with:
