description: Use when executing implementation plans with independent tasks. Dispatches subagents per task with two-stage review (spec then quality).

Subagent-Driven Development

Execute plan by dispatching subagents per task, with two-stage review after each: spec compliance review first, then code quality review.

Core principle: Fresh subagent per task + two-stage review (spec then quality) = high quality, fast iteration

When to Use

Use when:

  • You have an implementation plan with independent tasks
  • Tasks can be executed one at a time
  • You want automated review between tasks

The Process

For Each Task:

  1. Dispatch Implementer Subagent

    • Provide full task specification
    • Subagent implements, tests, commits
  2. Dispatch Spec Reviewer Subagent

    • Reviews if code matches specification
    • If gaps found → Implementer fixes
  3. Dispatch Code Quality Reviewer Subagent

    • Reviews code quality, patterns, best practices
    • If issues found → Implementer fixes
  4. Mark Task Complete

    • Update todo list
    • Move to next task

Example Workflow

code
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 todo list 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/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!

Advantages

vs. Manual execution:

  • Subagents follow TDD naturally
  • Fresh context per task (no confusion)
  • Parallel-safe (subagents don't interfere)
  • Subagent can ask questions (before AND during work)

vs. Executing Plans:

  • Same session (no handoff)
  • Continuous progress (no waiting)
  • Review checkpoints automatic

Quality gates:

  • Self-review catches issues before handoff
  • Two-stage review: spec compliance, then code quality
  • Review loops ensure fixes actually work
  • Spec compliance prevents over/under-building
  • Code quality ensures implementation is well-built

Red Flags

Never:

  • Skip reviews (spec compliance OR code quality)
  • Proceed with unfixed issues
  • Dispatch multiple implementation subagents in parallel (conflicts)
  • Make subagent read plan file (provide full text instead)
  • Skip scene-setting context (subagent needs to understand where task fits)
  • Ignore subagent questions (answer before letting them proceed)
  • Accept "close enough" on spec compliance (spec reviewer found issues = not done)
  • Skip review loops (reviewer found issues = implementer fixes = review again)
  • Let implementer self-review replace actual review (both are needed)
  • Start code quality review before spec compliance is ✅ (wrong order)
  • Move to next task while either review has open issues

If subagent asks questions:

  • Answer clearly and completely
  • Provide additional context if needed
  • Don't rush them into implementation

If reviewer finds issues:

  • Implementer (same subagent) fixes them
  • Reviewer reviews again
  • Repeat until approved
  • Don't skip the re-review

If subagent fails task:

  • Dispatch fix subagent with specific instructions
  • Don't try to fix manually (context pollution)

Integration

Works with these skills:

  • writing-plans - Creates the plan this skill executes
  • test-driven-development - Subagents follow TDD for each task
  • verification-before-completion - Ensure all verification passes

Alternative workflow:

  • executing-plans - Use for simpler execution without subagent dispatch
