Subagent-Driven Development

Execute plan by dispatching fresh subagent 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

• Have implementation plan? → yes
• Tasks mostly independent? → yes
• Stay in this session? → yes → use subagent-driven-development
• Need parallel session? → use executing-plans

The Process

1. Read plan, extract ALL tasks with full text + context
2. Create TodoWrite with all tasks

Per task:
  a. Dispatch implementer subagent (provide full task text + context)
  b. Answer any questions from subagent before proceeding
  c. Subagent implements, tests, commits, self-reviews
  d. Dispatch SPEC COMPLIANCE reviewer subagent
     → If fails: implementer fixes → re-review until ✅
  e. Dispatch CODE QUALITY reviewer subagent
     → If fails: implementer fixes → re-review until ✅
  f. Mark task complete

3. After all tasks: Dispatch final code reviewer for entire implementation
4. Use superpowers:finishing-a-development-branch

Two-Stage Review Order

1st: Spec Compliance — Does code match the spec? Nothing missing? Nothing extra?
2nd: Code Quality — Is the implementation well-built?
⚠️ Never start code quality review before spec compliance is ✅

Red Flags — Never:

• Start on main/master without explicit user consent
• Skip either review stage
• Proceed with unfixed issues
• Dispatch multiple implementation subagents in parallel (conflicts)
• Make subagent read plan file (provide full text instead)
• Accept "close enough" on spec compliance

Advantages vs. Manual Execution

• Subagents follow TDD naturally
• Fresh context per task (no confusion)
• Two-stage quality gates
• Questions surfaced before work begins (not after)

• Creates plan: superpowers:writing-plans
• After all tasks: superpowers:finishing-a-development-branch
