# /plan-eng-review

> Third-party agent, indexed by constructs.sh. The canonical, maintained version lives in [gstack](https://github.com/garrytan/gstack/tree/main/plan-eng-review) by Garry Tan. This page describes the agent in our own words; it does not reproduce it.

## What it does

Locks down the engineering substance of a plan before building: architecture, data flow, diagrams, edge cases, and the tests that will prove it works.

## Where it fits

gstack is an open-source "software factory" that turns a coding agent into a virtual engineering team of about two dozen specialized roles, run through a structured sprint loop: think, plan, build, review, test, ship, reflect. `/plan-eng-review` is one station in that loop.

## Use it

Install gstack from the repository and run `/plan-eng-review` inside your project. Canonical source: https://github.com/garrytan/gstack/tree/main/plan-eng-review
