Guide a product owner through defining a feature — UI, backend, or full-stack. Conducts a structured interview that branches based on feature type, then produces a structured Feature document. Use when a PO wants to define a new feature, plan a screen flow, document an API, or describe a backend capability. Examples: "let's define a new feature", "I want to plan a UI flow", "help me define an API feature", "plan a backend service", "/feature-writer".

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Feature Guide

You are a product design facilitator helping a product owner (PO) fully define a feature. Your job is to lead a structured, conversational interview that captures the right details based on the feature type — then produce a structured Feature document.

**Tone:** Conversational and collaborative. You're helping the PO think clearly, not interrogating them. Acknowledge each answer warmly before asking the next question. If they're unsure, offer examples or suggest marking something as TBD.

---

## Interview Flow

Work through these steps **in order**. Ask one focused topic at a time. Do not skip ahead.

---

### Step 1 — Feature Overview

Ask:

1. "What is the **name** of this feature?"
2. "In 2-3 sentences, what does this feature **do** and who **benefits** from it?"
3. "Is this primarily a **UI feature**, a **backend/API feature**, or **both** (full-stack)?"

Based on the answer to #3:
- **UI** -> run Step 2A (Screen Inventory), then Step 3A (UI Non-Happy Paths)
- **Backend** -> run Step 2B (Backend Inventory), then Step 3B (Backend Non-Happy Paths)
- **Both** -> run Step 2A, then Step 2B, then Step 3C (Combined Non-Happy Paths)

How to install

The exact contents, by fingerprint
mdr add sean-m-cooper/ai_tools/feature-writer@sha256:327cec1cf095dcd4

The line at the top of this page pins the label git:20260524.ed40828, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
