Skill2 starsChanged 3 months agoMITView on GitHub

Use when the user wants a formal project requirements document (PRD) written for an app, feature, or product idea. Use when they say "write a PRD", "create a project brief", "document my idea", or "let's write up the requirements" — including as the final step after an idea-interrogator and/or visual-identity session.

We split this skill into the rules it gives an agent

4 rules. 0 are common, 2 are distinctive, and 2 are very specific to this project.

  • 0

    Common

    Most of the 10 edited versions we read keep these.

  • 2

    Distinctive

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Check the current working directory for idea-interrogator-verdict.md and visual-identity.md.

    line 17
  2. Distinctive:

    Ask about anything the PRD still needs that neither file covers: target users, success metrics, explicit out-of-scope items.

    line 27
  3. Very specific:

    Write <project-name>-brief.md to the current working directory:

    line 38
  4. Distinctive:

    Keep tone practical — no marketing language, no filler adjectives.

    line 73

“Common” is measured: kept by at least 6 in 10 of the 10 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Project Brief

Overview

Produces a PRD-style document. Standalone-capable: reuses idea-interrogator-verdict.md and visual-identity.md from the current working directory when present instead of re-asking that ground, and asks the relevant questions directly when either file is missing. Never requires either file to run.

Process

  1. Check the current working directory for idea-interrogator-verdict.md and visual-identity.md.
  2. For whichever file IS present, read it and reuse its content instead of asking the user to repeat themselves.
  3. For whichever file is MISSING, ask the user directly:
    • No idea-interrogator-verdict.md: ask about scope, doability, time estimate, purpose, and MVP features before drafting the Validation Summary section.
    • No visual-identity.md: ask about fonts, colors, theme, and desired feeling before drafting the Design Direction section.
  4. Ask about anything the PRD still needs that neither file covers: target users, success metrics, explicit out-of-scope items.
  5. Draft the full document (structure below) and confirm it with the user before treating it as final.

The Validation Summary and Design Direction sections below are REQUIRED in every output document — never drop them, and never fold their content into other sections instead. If a source file is missing, fill the section from direct questions rather than omitting it.

Deliverable

Write <project-name>-brief.md to the current working directory:

# Project Brief: <project name>

## Overview
<what this is, in 2-4 sentences>

## Validation Summary
<pulled from idea-interrogator-verdict.md if present: verdict, key risk,
scope/time caveats — otherwise drafted from direct questions>

## Goals
- ...

## Target Users
- ...

## Design Direction
<pulled from visual-identity.md if present: condensed narrative + key tokens
(fonts, primary colors, theme) — otherwise drafted from direct questions>

## Features
### MVP
- ...
### Later / Explicitly Deferred
- ...

## Success Metrics
- ...

## Out of Scope
- ...

Keep tone practical — no marketing language, no filler adjectives.

Common Mistakes

  • Re-asking questions already answered in idea-interrogator-verdict.md or visual-identity.md — check for and read those files first.
  • Dropping the Validation Summary or Design Direction sections, or folding their content into other sections instead of keeping them as their own labeled headers — both are required sections in every output document.
  • Ignoring visual-identity.md even when present in cwd — every color/font/ token detail it contains belongs in the Design Direction section.
  • Treating a NO-GO verdict from idea-interrogator-verdict.md as a reason to refuse writing the brief — it's context for the Validation Summary, not a gate.
