You: I'm using Subagent-Driven Development to execute this plan.
 
[Read plan file once: docs/plans/feature-plan.md]
[Extract all 5 tasks with full text and context]
[Create TodoWrite with all tasks]
 
Task 1: Hook installation script
 
[Get Task 1 text and context (already extracted)]
[Dispatch implementation subagent with full task text + context]
 
Implementer: "Before I begin - should the hook be installed at user or system level?"
 
You: "User level (~/.config/devops-skills/hooks/)"
 
Implementer: "Got it. Implementing now..."
[Later] Implementer:
  - Implemented install-hook command
  - Added tests, 5/5 passing
  - Self-review: Found I missed --force flag, added it
  - Committed
 
[Dispatch spec compliance reviewer]
Spec reviewer: ✅ Spec compliant - all requirements met, nothing extra
 
[Get git SHAs, dispatch code quality reviewer]
Code reviewer: Strengths: Good test coverage, clean. Issues: None. Approved.
 
[Mark Task 1 complete]
 
Task 2: Recovery modes
 
[Get Task 2 text and context (already extracted)]
[Dispatch implementation subagent with full task text + context]
 
Implementer: [No questions, proceeds]
Implementer:
  - Added verify/repair modes
  - 8/8 tests passing
  - Self-review: All good
  - Committed
 
[Dispatch spec compliance reviewer]
Spec reviewer: ❌ Issues:
  - Missing: Progress reporting (spec says "report every 100 items")
  - Extra: Added --json flag (not requested)
 
[Implementer fixes issues]
Implementer: Removed --json flag, added progress reporting
 
[Spec reviewer reviews again]
Spec reviewer: ✅ Spec compliant now
 
[Dispatch code quality reviewer]
Code reviewer: Strengths: Solid. Issues (Important): Magic number (100)
 
[Implementer fixes]
Implementer: Extracted PROGRESS_INTERVAL constant
 
[Code reviewer reviews again]
Code reviewer: ✅ Approved
 
[Mark Task 2 complete]
 
...
 
[After all tasks]
[Dispatch final code-reviewer]
Final reviewer: All requirements met, ready to merge
 
Done!
