# Release Swarm - Intelligent Release Automation

## Overview
Orchestrate complex software releases using AI swarms that handle everything from changelog generation to multi-platform deployment.

## Core Features

### 1. Release Planning
```bash
# Plan next release using gh CLI
# Get commit history since last release
LAST_TAG=$(gh release list --limit 1 --json tagName -q '.[0].tagName')
COMMITS=$(gh api repos/:owner/:repo/compare/${LAST_TAG}...HEAD --jq '.commits')

# Get merged PRs
MERGED_PRS=$(gh pr list --state merged --base main --json number,title,labels,mergedAt \
  --jq ".[] | select(.mergedAt > \"$(gh release view $LAST_TAG --json publishedAt -q .publishedAt)\")")  

# Plan release with commit analysis
npx ruv-swarm github release-plan \
  --commits "$COMMITS" \
  --merged-prs "$MERGED_PRS" \
  --analyze-commits \
  --suggest-version \
  --identify-breaking \
  --generate-timeline
```

### 2. Automated Versioning
```bash
# Smart version bumping
npx ruv-swarm github release-version \
  --strategy "semantic" \
  --analyze-changes \
  --check-breaking \
  --update-files
```

### 3. Release Orchestration
```bash
# Full release automation with gh CLI
# Generate changelog from PRs and commits
CHANGELOG=$(gh api repos/:owner/:repo/compare/${LAST_TAG}...HEAD \
  --jq '.commits[].commit.message' | \
  npx ruv-swarm github generate-changelog)

# Create release draft
gh release create v2.0.0 \
  --draft \
  --title "Release v2.0.0" \
  --notes "$CHANGELOG" \
  --target main

# Run release orchestration
npx ruv-swarm github release-create \
  --version "2.0.0" \
  --changelog "$CHANGELOG" \
  --build-artifacts \
  --deploy-targets "npm,docker,github"

# Publish release after validation
gh release edit v2.0.0 --draft=false

# Create announcement issue
gh issue create \
  --title "🎉 Released v2.0.0" \
  --body "$CHANGELOG" \
  --label "announcement,release"
```

## Release Agents

### Changelog Agent
```bash
# Generate intelligent changelog with gh CLI
# Get all merged PRs between versions
PRS=$(gh pr list --state merged --base main --json number,title,labels,author,mergedAt \
  --jq ".[] | select(.mergedAt > \"$(gh release view v1.0.0 --json publishedAt -q .publishedAt)\")")  

# Get contributors
CONTRIBUTORS=$(echo "$PRS" | jq -r '[.author.login] | unique | join(", ")')

# Get commit messages
COMMITS=$(gh api repos/:owner/:repo/compare/v1.0.0...HEAD \
  --jq '.commits[].commit.message')

# Generate categorized changelog
CHANGELOG=$(npx ruv-swarm github changelog \
  --prs "$PRS" \
  --commits "$COMMITS" \
  --contributors "$CONTRIBUTORS" \
  --from v1.0.0 \
  --to HEAD \
  --categorize \
  --add-migration-guide)

# Save changelog
echo "$CHANGELOG" > CHANGELOG.md

# Create PR with changelog update
