Translate ideas, feature requests, or vague concepts into specific, actionable dev briefs. Use this skill whenever the user has an idea they want to build, a feature to spec out, a bug to file, a project to scope, or needs to convert a half-formed idea into a clear implementation brief.

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

# PM Spec Writing

Take an idea (often vague) and turn it into a specification a developer or AI agent can actually build from. Stack-agnostic. Works for new features, bug fixes, content changes, or infrastructure work.

---

## When to use

- Translating an idea into a buildable feature spec
- Writing a PRD or product requirement document
- Filing a bug report that someone else can act on
- Scoping a project before kickoff
- Prioritizing a backlog of feature requests
- Writing acceptance criteria for an existing feature
- Breaking a large initiative into shippable increments

## When NOT to use

- Quarterly or annual planning across multiple initiatives (use `roadmap-planning`)
- Code review or debugging existing code (use `code-review-web`)
- Design decisions for a feature already specced (use `design-standards`)
- User research to validate an idea (use `ux-research`)

---

## Required inputs

- The idea, request, or problem being addressed
- The audience or user affected
- Any existing constraints (stack, deadlines, dependencies)
- The success metric (how will you know it worked?)

How to install

The exact contents, by fingerprint
mdr add rampstackco/claude-skills/pm-spec-writing@sha256:17c08255d5ba55c2

The line at the top of this page pins the label git:20260810.e5bc675, 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.
