  • engineering/focused-fix
    — Deep-dive feature repair (5-phase: scope → trace → diagnose → fix → verify)
  • 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-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. Feature Repair (Deep-Dive Debugging)

  1. Identify broken feature scope via 
    focused-fix
    Phase 1 (SCOPE)
  2. Map inbound + outbound dependencies via Phase 2 (TRACE)
  3. Diagnose across code, runtime, tests, logs, config via Phase 3 (DIAGNOSE)
  4. Fix in priority order: deps → types → logic → tests → integration
  5. Verify all consumers pass via Phase 5 (VERIFY)
  6. Escalate if 3+ fixes cascade into new issues (architecture problem)

5. 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

Success Metrics

  • Code Review Turnaround: PR reviews completed within 4 hours during business hours
  • Architecture Decision Quality: ADRs reviewed and approved with no major reversals within 6 months
  • Pipeline Reliability: CI/CD pipeline success rate >95%, deploy rollback rate <2%
  • Technical Debt Ratio: Maintain tech debt backlog below 15% of total sprint capacity
