# Plan Review Gate

## Overview

Three independent adversarial reviewers validate any implementation plan before it is presented to the user. Each reviews independently with no shared context.

## When to Use

- After the Architect creates an implementation plan
- Before presenting a plan for user approval
- When validating work unit decomposition quality

## Process

1. **Feasibility Reviewer** - Can this plan actually be implemented? Technical viability, resource requirements, timeline reality
2. **Completeness Reviewer** - Does the plan cover everything? Missing edge cases, untested paths, incomplete DoD items
3. **Scope & Alignment Reviewer** - Does the plan match the issue? Scope creep detection, requirement traceability

All 3 must PASS before the plan is presented.

## Key Rules

- Reviewers operate independently (no shared context)
- Each provides a binary PASS/FAIL verdict
- Findings include specific references to plan sections
- Failed plans require revision before re-review
