• engineering/database-designer — Schema design, query optimization, migrations
• engineering/api-design-reviewer — REST/GraphQL API contract review
• engineering/migration-architect — System migration planning
• engineering-team/senior-architect — High-level architecture patterns
• engineering-team/senior-backend — Backend implementation patterns

Code Quality & Review

• engineering/pr-review-expert — Pull request review methodology
• engineering-team/code-reviewer — Code quality analysis
• engineering-team/tdd-guide — Test-driven development
• engineering-team/senior-qa — Quality assurance strategy

DevOps & Delivery

• engineering/ci-cd-pipeline-builder — Pipeline generation (GitHub Actions, GitLab CI)
• engineering/release-manager — Release planning and execution
• engineering-team/senior-devops — Infrastructure and deployment
• engineering/observability-designer — Monitoring and alerting

Security

• engineering-team/senior-security — Application security
• engineering-team/senior-secops — Security operations
• engineering/dependency-auditor — Supply chain security

Core Workflows

1. System Architecture Design

1. Gather requirements (scale, team size, constraints)
2. Evaluate architecture patterns via senior-architect
3. Design database schema via database-designer
4. Define API contracts via api-design-reviewer
5. Plan CI/CD pipeline via ci-cd-pipeline-builder
6. Document ADRs

2. Production Code Review

1. Understand the change context (PR description, linked issues)
2. Review code quality via code-reviewer + pr-review-expert
3. Check test coverage via tdd-guide
4. Assess security implications via senior-security
5. Verify deployment safety via senior-devops

3. CI/CD Pipeline Setup

1. Detect stack and tooling via ci-cd-pipeline-builder
2. Generate pipeline config (build, test, lint, deploy stages)
3. Add security scanning via dependency-auditor
4. Configure observability via observability-designer
5. Set up release process via release-manager

4. Technical Debt Assessment

1. Scan codebase via tech-debt-tracker
2. Score and prioritize debt items
3. Create remediation plan with effort estimates
4. Integrate into sprint backlog

Output Standards

• Architecture decisions → ADR format (context, decision, consequences)
• Code reviews → structured feedback (severity, file, line, suggestion)
• Pipeline configs → validated YAML with comments
• All recommendations include tradeoff analysis
