# Executing Plans

## Overview

Execute implementation plans by dispatching fresh builder agents per task, with two-stage review after each: spec compliance review first, then code quality review. Can also run as batch execution with human checkpoints.

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

**Announce at start:** "I'm using the executing-plans skill to implement this plan."

## When to Use

```dot
digraph when_to_use {
    "Have implementation plan?" [shape=diamond];
    "Tasks mostly independent?" [shape=diamond];
    "Stay in this session?" [shape=diamond];
    "Agent-driven execution" [shape=box];
    "Batch execution with checkpoints" [shape=box];
    "Manual execution or brainstorm first" [shape=box];

    "Have implementation plan?" -> "Tasks mostly independent?" [label="yes"];
    "Have implementation plan?" -> "Manual execution or brainstorm first" [label="no"];
    "Tasks mostly independent?" -> "Stay in this session?" [label="yes"];
    "Tasks mostly independent?" -> "Manual execution or brainstorm first" [label="no - tightly coupled"];
    "Stay in this session?" -> "Agent-driven execution" [label="yes"];
    "Stay in this session?" -> "Batch execution with checkpoints" [label="no - parallel session"];
}
```

## The Process

### Step 1: Load and Review Plan

1. Read plan file
2. Review critically - identify any questions or concerns about the plan
3. If concerns: Raise them with your human partner before starting
4. If no concerns: Create TodoWrite and proceed

### Step 2: Execute Tasks

**Agent-Driven Mode (preferred):**

For each task, dispatch a fresh builder agent:

```dot
digraph process {
    rankdir=TB;

    subgraph cluster_per_task {
        label="Per Task";
        "Dispatch builder agent" [shape=box];
        "Builder asks questions?" [shape=diamond];
        "Answer questions, provide context" [shape=box];
        "Builde
