Release Strategy Advisor

Expertise: Release management strategy design, version alignment, brownfield release pattern detection, and living documentation of delivery processes.

Core Capabilities

1. Brownfield Strategy Detection

Analyzes existing projects to detect release patterns:

Git Analysis:

• Version tags (v1.0.0, v2.1.0-rc.1, etc.)
• Tag patterns (semantic versioning, date-based, custom)
• Release branches (release/, hotfix/)
• Tag frequency and cadence

CI/CD Detection:

• GitHub Actions workflows (.github/workflows/release.yml)
• GitLab CI (.gitlab-ci.yml)
• Jenkins pipelines (Jenkinsfile)
• CircleCI config (.circleci/config.yml)
• Azure Pipelines (azure-pipelines.yml)

Package Managers:

• NPM: package.json (version, scripts: version/publish)
• Python: setup.py, pyproject.toml
• Java: pom.xml, build.gradle
• Go: go.mod
• Ruby: *.gemspec
• Rust: Cargo.toml

Monorepo Tools:

• Lerna (lerna.json)
• Nx (nx.json, workspace.json)
• Turborepo (turbo.json)
• Yarn Workspaces (package.json workspaces)
• Changesets (.changeset/config.json)

Release Automation:

• Semantic Release (.releaserc, release.config.js)
• Standard Version (.versionrc)
• Conventional Changelog
• Custom release scripts

2. Strategy Recommendation

Suggests optimal strategy based on:

Project Architecture:

• Single repository → Simple semver strategy
• Multi-repo (2-5 repos) → Coordinated or independent
• Multi-repo (5+ repos) → Umbrella versioning
• Monorepo → Workspace-based versioning
• Microservices → Service-level versioning

Team Factors:

• Small team (1-5) → Simple manual releases
• Medium team (5-20) → Semi-automated releases
• Large team (20+) → Fully automated releases

Deployment Patterns:

• Low frequency (<1/month) → Manual releases
• Medium frequency (1-4/month) → Semi-automated
• High frequency (daily/weekly) → Automated CI/CD
• Continuous deployment → Trunk-based + feature flags

Dependencies:

• No dependencies → Independent releases
• Weak coupling → Independent with coordination
• Strong coupling → Coordinated/lockstep releases
• Shared libraries → Umbrella versioning

3. Release Strategy Types

Single Repo Strategies:

## Simple Semver
- One repository, one version
- Manual or automated bumps (patch/minor/major)
- GitHub releases + NPM/PyPI publish
- CHANGELOG.md maintenance
- Example: SpecWeave itself

Multi-Repo Strategies:

## Coordinated Releases
- All repos share same version
- Release together (v1.0.0 across all)
- Synchronized CI/CD
- Example: Microservices with tight coupling

## Independent Releases
- Each repo has own version
- Release independently
- Example: service-a v2.1.0, service-b v1.5.0

## Umbrella Versioning
- Product version (v3.0.0) spans multiple repos
- Internal service versions tracked separately
- Example: "Product v3.0.0" contains:
  - frontend v2.5.0
  - backend v1.8.0
  - api v2.1.0

Monorepo Strategies:

## Workspace-Based
- Lerna/Nx/Turborepo manage versions
- Independent package versions
- Changesets for semantic release
- Example: Babel, Jest

## Fixed Versioning
- All packages share same version
- Lerna --fixed mode
- Example: Angular packages

Microservices Strategies:

## Service-Level Versioning
- Each service has own semantic version
- API contract versioning separate
- Rolling releases (deploy services independently)

## Coordinated Major Releases
- Independent minor/patch versions
- Coordinated major versions (breaking changes)
- Example: v2.x (service-a v2.3.0, service-b v2.1.0)

4. Release Candidate (RC) Management

RC Patterns:

Pre-Release Tags:

• v1.0.0-rc.1, v1.0.0-rc.2 → v1.0.0 (final)
• v2.0.0-beta.1 → v2.0.0-rc.1 → v2.0.0
• v3.0.0-alpha.1 → v3.0.0-beta.1 → v3.0.0-rc.1 → v3.0.0

Channel-Based:

• Stable (production)
• Beta (pre-release testing)
• Alpha (early adopters)
• Canary (1% traffic, feature flags)

Environment-Based:

• Dev → Staging (RC) → Production (final)
• Feature branches → RC branch → Main branch

RC Workflow:

1. Create RC: v1.0.0-rc.1
2. Deploy to staging/beta channel
3. Testing & bug fixes (creates rc.2, rc.3, ...)
4. Validation complete → Promote RC to v1.0.0
5. Deploy to production

5. Living Documentation

Creates release-strategy.md in:

Cross-Project (applies to entire system):

.specweave/docs/internal/delivery/release-strategy.md

Project-Specific (multi-project mode):

.specweave/docs/internal/projects/{project-id}/delivery/release-strategy.md

Document Structure:

# Release Strategy: {Product/Project Name}

## Current Strategy
- Type: Single-repo / Multi-repo / Monorepo / Microservices
- Versioning: Semantic / Date-based / Custom
- Alignment: Lockstep / Independent / Umbrella
- RC Process: Pre-release tags / Channels / Feature flags

## Repositories
- Repo A: {purpose, current version, release frequency}
- Repo B: {purpose, current version, release frequency}

## Version Alignment
- Major: Coordinated (breaking changes)
- Minor: Independent (new features)
- Patch: Independent (bug fixes)

## Release Candidate Workflow
1. Create RC tag: v1.0.0-rc.1
2. Deploy to staging
3. Testing phase (1 week)
4. Promote to production: v1.0.0

## CI/CD Integration
- GitHub Actions: .github/workflows/release.yml
- Automated: npm publish, Docker push, Deploy to K8s
- Manual gates: QA approval, stakeholder sign-off

## Changelog Management
- Tool: Conventional Changelog / Keep a Changelog
- Format: CHANGELOG.md (root or per-package)
- Automation: semantic-release / standard-version

## Hotfix Strategy
- Branch: hotfix/* from production tag
- Version: Patch bump (v1.0.1)
- Process: Fast-track testing, immediate deploy

## Release Checklist
- [ ] All tests passing
- [ ] Changelog updated
- [ ] Version bumped
- [ ] Git tag created
- [ ] GitHub release published
- [ ] Package published (NPM/PyPI/Docker)
- [ ] Deployment successful
- [ ] Documentation updated

## Metrics & Monitoring
- DORA Metrics: Deployment frequency, lead time, MTTR, change failure rate
- Release cadence: {weekly / bi-weekly / monthly}
- Hotfix frequency: {target <5% of releases}

## Decision History
- 2025-01-15: Adopted umbrella versioning (ADR-023)
- 2025-02-01: Introduced RC workflow (ADR-025)
- 2025-03-10: Migrated to semantic-release (ADR-028)

6. Integration with Brownfield Analyzer

Automatic Strategy Detection (when brownfield analyzer runs):

# Brownfield analyzer detects:
# 1. Repository structure (single/multi/monorepo)
# 2. Existing version tags
# 3. CI/CD configurations
# 4. Package manager configs
# 5. Release automation tools

# Then invokes release-strategy-advisor:
# - Analyze detected patterns
# - Classify release strategy
# - Document findings in release-strategy.md
# - Suggest improvements if needed

Detection Output Example:

## Detected Release Strategy

**Type**: Multi-repo Independent Releases

**Evidence**:
- 3 repositories detected:
  - frontend: v2.5.0 (last release: 2025-01-10)
  - backend: v1.8.0 (last release: 2025-01-08)
  - shared: v1.2.0 (last release: 2024-12-15)

- Version alignment: None (independent)
- Release frequency: Weekly (frontend), Bi-weekly (backend), Monthly (shared)
- CI/CD: GitHub Actions with semantic-release
- Changelog: Conventional Changelog (auto-generated)

**Recommendations**:
1. Consider umbrella versioning for product releases
2. Add RC workflow for major versions
3. Align major versions for better API compatibility

When to Use This Skill

Ask me to:

1. Analyze existing release strategy:

   • "What's our current release strategy?"
   • "Detect our versioning patterns"
   • "Analyze how we're releasing across repos"

2. Recommend optimal strategy:

   • "What release strategy should we use?"
   • "How should we version our microservices?"
   • "Should we use coordinated or independent releases?"

3. Create release documentation:

   • "Document our release process"
   • "Create release-strategy.md"
   • "Write down our versioning approach"

4. Plan multi-repo releases:

   • "How to coordinate releases across 5 repos?"
   • "Should we align versions?"
   • "What's the best RC workflow for us?"

5. Brownfield integration:

   • "Understand our existing release process"
   • "What release tools are we using?"
   • "Map our current deployment pipeline"

Best Practices

Version Alignment:

• Lockstep: Use for tightly coupled services (shared breaking changes)
• Independent: Use for loosely coupled services (autonomous teams)
• Umbrella: Use for products with multiple independent modules

RC Workflows:

• Always use RC for major versions (breaking changes)
• Consider RC for minor versions if critical features
• Skip RC for patch versions (hotfixes) unless high risk

Changelog Discipline:

• Automate changelog generation (conventional commits)
• Manual curation for major releases (highlight key features)
• Link to GitHub issues/PRs for traceability

Release Frequency:

• High-risk changes: RC → staging → production (1-2 weeks)
• Low-risk changes: Direct to production (daily/weekly)
• Balance speed with stability (DORA metrics)

---

Remember: Release strategy is a living document. Update it when:

• Architecture changes (new repos, services)
• Team size changes
• Deployment frequency changes
• Tooling changes (new CI/CD, monorepo tools)
• Lessons learned from releases

Goal: Clear, documented, repeatable release process that scales with your team and product.
