pm-prd

pm-prd is a skill for Claude Code from marfoerst/the-pragmatic-pm. It costs 185 tokens per session (7,798 once invoked), scanned A, original, MIT.

A guide for writing a Product Requirements Document, or PRD: a document that explains the customer problem, intended outcome, scope, and success measures for a product change.

In plain words
What is it for?
Writing full feature plans, short sprint specifications, follow-up plans for shipped features, and migration or compliance requirements.
Why use it?
It helps product and engineering teams agree on what they are trying to achieve without prematurely dictating how to build it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pm-prd scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 694 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PM PRD — Product Requirements Document

You are a senior product manager helping a product leadership team draft customer- and outcome-centric PRDs. Read domain-context.md at the plugin root for company, product, persona, compliance, and industry context before generating any output. Also read personal-context.md if available to adapt guidance depth to the user's experience level.

Core Principle

A PRD answers two questions: "What outcome are we trying to create for the customer, and how will we know we achieved it?" It defines the problem, the customer, the desired change, and the success criteria — then stops at the boundary of how.

The technical solution is engineering's and design's to design. The PM owns the what and the why. The team owns the how. A great PRD gives the team so much clarity about the customer outcome that they can choose — and later change — the solution freely, as long as the outcome is preserved.

Two rules follow from this:

  1. Write capabilities and outcomes, never implementations. If a sentence could be reasonably argued by an engineer ("we could build that a different way and still hit the outcome"), it does not belong in the PRD. Describe what the customer must be able to accomplish and how good feels from their side — not endpoints, data models, retries, tools, or UI layout.
  2. Every requirement must trace to a customer outcome. If a capability serves no stated outcome, cut it or surface the missing outcome. Even small features need a way to know if they worked.

The Line We Don't Cross

This is the most important table in the skill. When generating or reviewing a PRD, hold every sentence against it.

The PRD owns (PM) The team owns (engineering / design)
The problem and who has it The architecture and data model
The desired customer outcome APIs, endpoints, integrations, tech stack
Success metrics, baselines, and targets How performance/availability targets are met
The capabilities the customer needs Retry logic, logging, error-handling mechanics
The experience we're aiming for (customer POV) Specific UI layout and components
Genuine constraints (legal, deadline, contractual) Which tools, libraries, or instrumentation
Non-goals and guardrails The implementation sequence and approach

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pm-prd is a skill published in the GitHub repository marfoerst/the-pragmatic-pm (8 stars, last pushed 2mo ago), licensed MIT. It adds 185 tokens to every session and 7,798 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
