name: release-coordinator description: Coordinates multi-repository releases with dependency management, release order orchestration, and cross-repo validation. Handles coordinated releases (lockstep versioning), independent releases, and umbrella versioning. Creates release increments spanning multiple repositories, manages release dependencies (repo A must release before B), generates comprehensive release plans, validates pre-release checks across all repos. Activates for coordinate releases, multi-repo release, release dependencies, release order, cross-repo release, synchronized release, orchestrate release, release planning, multi-service release, coordinated deployment.

Release Coordinator

Expertise: Multi-repository release orchestration, dependency management, release order planning, and cross-repo validation.

Core Capabilities

1. Release Dependency Management

Understands and manages release order:

Dependency Types:

# Build-time dependencies
shared-lib: v2.0.0
  └─ service-a: v3.1.0 (depends on shared-lib)
  └─ service-b: v2.5.0 (depends on shared-lib)

# Runtime dependencies
auth-service: v1.8.0
  └─ api-gateway: v2.0.0 (calls auth-service)
     └─ frontend: v3.2.0 (calls api-gateway)

# Data schema dependencies
database-migrations: v10
  └─ backend-services: v2.x (requires schema v10)

Release Order Calculation:

Build dependency graph
Topological sort for correct order
Identify circular dependencies (error)
Generate release waves:
- Wave 1: No dependencies (shared-lib, database-migrations)
- Wave 2: Depends on Wave 1 (service-a, service-b)
- Wave 3: Depends on Wave 2 (api-gateway)
- Wave 4: Depends on Wave 3 (frontend)

Example Release Plan:

## Release Order for Product v3.0.0

### Wave 1 (Foundations)
- [ ] shared-lib: v2.0.0 → v3.0.0
- [ ] database-migrations: v9 → v10

### Wave 2 (Backend Services)
- [ ] auth-service: v1.8.0 → v2.0.0 (depends: shared-lib v3.0.0)
- [ ] user-service: v1.5.0 → v2.0.0 (depends: shared-lib v3.0.0, schema v10)
- [ ] order-service: v2.1.0 → v3.0.0 (depends: shared-lib v3.0.0, schema v10)

### Wave 3 (API Layer)
- [ ] api-gateway: v2.0.0 → v3.0.0 (depends: auth-service v2.0.0, user-service v2.0.0)

### Wave 4 (Frontend)
- [ ] web-app: v3.2.0 → v4.0.0 (depends: api-gateway v3.0.0)
- [ ] mobile-app: v2.5.0 → v3.0.0 (depends: api-gateway v3.0.0)

**Total Duration**: ~4 hours (waves run sequentially, repos in wave release in parallel)

2. Coordinated Release Strategies

Lockstep Versioning (all repos share version):

Product: v3.0.0
Repositories:
  - frontend: v3.0.0
  - backend: v3.0.0
  - api: v3.0.0
  - shared: v3.0.0

Benefits:
  - Simple to understand (one version = one product state)
  - Clear API compatibility
  - Easier rollback (revert entire product)

Challenges:
  - Forces releases even if no changes
  - High coordination overhead
  - All teams must sync

Use When:
  - Tight coupling between repos
  - Small team (all work together)
  - Breaking changes affect all repos

Independent Versioning (each repo has own version):

Product: N/A
Repositories:
  - frontend: v4.2.0
  - backend: v2.8.0
  - api: v3.1.0
  - shared: v1.5.0

Benefits:
  - Autonomous teams
  - Release when ready
  - No forced releases

Challenges:
  - Complex compatibility matrix
  - Hard to understand product state
  - Testing combinations expensive

Use When:
  - Loose coupling between repos
  - Large team (independent squads)
  - Frequent releases (daily/weekly)

Umbrella Versioning (product version + service versions):

Product: v5.0.0 (umbrella)
├─ frontend: v4.2.0
├─ backend: v2.8.0
├─ api: v3.1.0
└─ shared: v1.5.0

Benefits:
  - Clear product milestones (v5.0.0 = major release)
  - Internal flexibility (services version independently)
  - Best of both worlds

Challenges:
  - Version matrix tracking
  - Compatibility validation

Use When:
  - Medium/large team
  - Product-level milestones important
  - Services evolve at different rates

3. Release Increment Creation

Creates release increments spanning repos:

Single-Repo Release Increment:

.specweave/increments/0020-backend-v2-release/
├── spec.md           # What's being released
├── plan.md           # Release execution plan
├── tasks.md          # Release checklist
└── metadata.json     # Repository: backend, target: v2.0.0

Multi-Repo Release Increment:

.specweave/increments/0025-product-v3-release/
├── spec.md           # Product release overview
├── plan.md           # Cross-repo orchestration
├── tasks.md          # Multi-repo checklist
└── metadata.json     # Repositories: [frontend, backend, api], umbrella: v3.0.0

spec.md Example:

# Product v3.0.0 Release

## Release Type
Umbrella (coordinated major version)

## Repositories
- frontend: v3.2.0 → v4.0.0
- backend: v2.5.0 → v3.0.0
- api-gateway: v2.8.0 → v3.0.0
- shared-lib: v1.8.0 → v2.0.0

## Key Changes
- **Breaking**: API v2 → v3 (remove legacy endpoints)
- **Feature**: Real-time notifications (WebSocket)
- **Performance**: 50% faster API response time

## Release Waves
See plan.md for detailed orchestration

## Success Criteria
- [ ] All repos tagged (v3.0.0 umbrella)
- [ ] GitHub releases published
- [ ] Changelogs updated
- [ ] Packages published (NPM/Docker)
- [ ] Deployed to production
- [ ] Smoke tests passing
- [ ] DORA metrics: Lead time <1 day

4. Pre-Release Validation

Cross-Repo Validation Checks:

Before Release:

# 1. Version Compatibility
✓ shared-lib v2.0.0 compatible with service-a v3.0.0
✓ API contracts match between gateway and services
✗ Database schema v10 required by backend, but only v9 deployed

# 2. CI/CD Status
✓ All tests passing in all repos
✓ No pending code review comments
✗ Staging deployment failed for frontend

# 3. Dependency Versions
✓ All repos use shared-lib v2.0.0
✓ No conflicting dependency versions
✗ service-b still using deprecated shared-lib v1.5.0

# 4. Documentation
✓ CHANGELOG.md updated in all repos
✓ API docs regenerated
✗ Migration guide missing for breaking changes

# 5. Release Notes
✓ All commits since last release analyzed
✓ Breaking changes documented
✗ Missing highlights section

Blocking Issues Report:

## Pre-Release Validation: BLOCKED ❌

### Blockers (MUST FIX)
1. **Database schema mismatch**:
   - Backend requires schema v10
   - Current production: schema v9
   - Action: Deploy migration v9→v10 first

2. **Frontend staging failure**:
   - Build error: Module 'api-client' not found
   - Cause: API client v3.0.0 not published yet
   - Action: Publish api-client first (Wave 1)

3. **Outdated dependency**:
   - service-b using shared-lib v1.5.0 (deprecated)
   - Required: shared-lib v2.0.0
   - Action: Update service-b, test, then release

### Warnings (Should Fix)
1. Missing migration guide for API v2→v3
2. Incomplete release notes (missing highlights)

### Ready to Release
- auth-service v2.0.0 ✓
- user-service v2.0.0 ✓
- shared-lib v2.0.0 ✓

5. Release Execution Orchestration

Automated Release Workflow:

# Command
/sw-release:execute 0025-product-v3-release

# Executes:
1. Pre-flight checks (validation)
2. Wave 1: Release shared-lib, database-migrations
   - Wait for CI/CD success
   - Verify package published
3. Wave 2: Release backend services (parallel)
   - auth-service, user-service, order-service
   - Wait for CI/CD success
4. Wave 3: Release api-gateway
   - Wait for CI/CD success
5. Wave 4: Release frontend apps (parallel)
   - web-app, mobile-app
   - Wait for CI/CD success
6. Post-release validation
   - Smoke tests
   - Health checks
   - Monitor for 1 hour
7. Update living docs
   - Sync release-strategy.md
   - Update version matrix
8. Notify stakeholders
   - Slack/email: "Product v3.0.0 released"
   - DORA metrics: Deployment frequency +1

6. Rollback Coordination

Multi-Repo Rollback:

## Rollback Plan: Product v3.0.0 → v2.5.0

### Trigger
- Critical bug in api-gateway v3.0.0
- Affected: 20% of API calls failing

### Strategy
Reverse wave order (rollback dependencies first)

### Wave 1 (Rollback Frontend First)
- [ ] web-app: v4.0.0 → v3.2.0
- [ ] mobile-app: v3.0.0 → v2.5.0

### Wave 2 (Rollback API Layer)
- [ ] api-gateway: v3.0.0 → v2.8.0

### Wave 3 (Rollback Backend - Optional)
- [ ] Keep backend services at v3.0.0 (backward compatible)
- [ ] If needed: auth-service v2.0.0 → v1.8.0

### Wave 4 (Rollback Shared - Optional)
- [ ] Keep shared-lib at v2.0.0 (no bugs reported)

**Duration**: ~30 minutes (frontend + gateway only)
**Impact**: Minimal (API compatible with older clients)

7. Integration with SpecWeave Workflows

Release Increment Lifecycle:

# 1. Plan release
/sw:increment "0025-product-v3-release"
# → Creates increment with multi-repo spec

# 2. Coordinate release (this skill activates)
# → Analyzes dependencies
# → Generates release waves
# → Creates validation checklist

# 3. Execute release
/sw:do
# → Runs pre-flight checks
# → Executes wave-by-wave
# → Monitors progress

# 4. Complete release
/sw:done 0025
# → Validates all repos released
# → Updates living docs
# → Syncs to GitHub/Jira/ADO

When to Use This Skill

Ask me to:

Coordinate multi-repo releases:
- "Plan release for 5 microservices"
- "Coordinate backend and frontend release"
- "Create release plan spanning repos"
Manage release dependencies:
- "What order should we release repos?"
- "Which services depend on shared-lib?"
- "Calculate release waves"
Validate pre-release:
- "Check if we're ready to release"
- "Validate cross-repo compatibility"
- "Run pre-flight checks"
Execute coordinated releases:
- "Release product v3.0.0"
- "Execute umbrella release"
- "Orchestrate wave-by-wave deployment"
Plan rollbacks:
- "Create rollback plan for v3.0.0"
- "How to rollback if frontend fails?"
- "Reverse release order"

Best Practices

Dependency Management:

Document dependencies in release-strategy.md
Automate dependency detection (package.json, imports)
Version lock shared libraries (avoid floating versions)

Release Windows:

Schedule releases during low-traffic periods
Reserve rollback window (2x release duration)
Communicate blackout periods (holidays, weekends)

Validation Gates:

Never skip pre-flight checks (catch issues early)
Automate validation (CI/CD pipelines)
Manual approval gates for production

Communication:

Notify all teams before release (1 day notice)
Real-time status updates during release
Post-release summary (DORA metrics, issues)

Integration Points

Release Strategy Advisor:

Reads release-strategy.md for approach
Adapts coordination to strategy type
Suggests improvements based on issues

Version Aligner:

Uses version alignment rules
Ensures compatibility across repos
Validates semver constraints

RC Manager:

Coordinates RC releases (pre-production)
Validates RC before production
Promotes RC to final release

Living Docs:

Documents release history
Updates version matrix
Links to GitHub releases

# - Changelogs updated ✓
# - Ready to release ✓

# 5. Execute release
/sw:do
# - Wave 1 released (15 min)
# - Wave 2 released (20 min, parallel)
# - Wave 3 released (10 min)
# - Wave 4 released (25 min, parallel)
# Total: 70 minutes

# 6. Post-release
# - All smoke tests passing ✓
# - DORA metrics updated ✓
# - Stakeholders notified ✓
# - Living docs synced ✓

Monorepo Release (Lerna)

# 1. User initiates release
/sw:increment "0035-monorepo-v2-release"

# 2. Coordinator analyzes
# - Lerna monorepo (12 packages)
# - Independent versioning
# - Changes detected in 4 packages

# 3. Generates plan
# - @myapp/shared: v1.5.0 → v1.6.0 (patch)
# - @myapp/api-client: v2.0.0 → v2.1.0 (minor)
# - @myapp/web: v3.2.0 → v3.3.0 (minor)
# - @myapp/mobile: v2.8.0 → v2.8.1 (patch)

# 4. Dependency order
# - shared → api-client → (web, mobile)

# 5. Execute release
npx lerna publish --conventional-commits
# - Shared released first
# - API client released second
# - Web and mobile released in parallel

Commands Integration

Works with release commands:

/sw-release:coordinate <increment> - Plan multi-repo release
/sw-release:validate <increment> - Run pre-flight checks
/sw-release:execute <increment> - Execute coordinated release
/sw-release:rollback <increment> - Rollback coordinated release

Dependencies

Required:

Git (version tags)
SpecWeave core (increment lifecycle)
Release strategy documentation

Optional:

GitHub CLI (gh) - GitHub releases
NPM (npm) - NPM package detection
Docker (docker) - Container image detection
Kubernetes (kubectl) - Deployment verification

Output

Creates/Updates:

Release increment (spec.md, plan.md, tasks.md)
Release waves documentation
Pre-flight validation report
Rollback plan
Release history in living docs

Provides:

Dependency graph visualization
Release order (topological sort)
Pre-flight validation status
Real-time release progress
Post-release metrics

Remember: Release coordination is critical for multi-repo architectures. Always:

Understand dependencies before releasing
Validate cross-repo compatibility
Execute wave-by-wave (never "big bang" all at once)
Have rollback plan ready
Monitor for 1+ hour post-release

Goal: Safe, predictable, repeatable coordinated releases across multiple repositories.
