# Subagent-Driven Development

Execute plan by dispatching fresh subagent per task, with code review after each.

**Core principle:** Fresh subagent per task + review between tasks = high quality, fast iteration

## Overview

**vs. Executing Plans (parallel session):**
- Same session (no context switch)
- Fresh subagent per task (no context pollution)
- Code review after each task (catch issues early)
- Faster iteration (no human-in-loop between tasks)

**When to use:**
- Staying in this session
- Tasks are mostly independent
- Want continuous progress with quality gates

**When NOT to use:**
- Need to review plan first (use executing-plans)
- Tasks are tightly coupled (manual execution better)
- Plan needs revision (brainstorm first)

## The Process

### 1. Load Plan

Read plan file, use TaskCreate to create all tasks.

### 2. Execute Task with Subagent

For each task:

**Dispatch fresh subagent:**
```
Task tool (general-purpose):
  description: "Implement Task N: [task name]"
  prompt: |
    You are implementing Task N from [plan-file].

    Read that task carefully. Your job is to:
    1. Implement exactly what the task specifies
    2. Write tests (following TDD if task says to)
    3. Verify implementation works
    4. Commit your work
    5. Report back

    Work from: [directory]

    Report: What you implemented, what you tested, test results, files changed, any issues
```

**Subagent reports back** with summary of work.

### 3. Review Subagent's Work

**Dispatch code-reviewer subagent:**
```
Task tool (superpowers:code-reviewer):
  Use template at requesting-code-review/code-reviewer.md

  WHAT_WAS_IMPLEMENTED: [from subagent's report]
  PLAN_OR_REQUIREMENTS: Task N from [plan-file]
  BASE_SHA: [commit before task]
  HEAD_SHA: [current commit]
  DESCRIPTION: [task summary]
```

**Code reviewer returns:** Strengths, Issues (Critical/Important/Minor), Assessment

### 4. Apply Review Feedback

**If issues found:**
- Fix Critical issues immediately
- Fix Import
