phuryn/pm-skills for Claude Code: install and use

What problem does phuryn/pm-skills solve?

Product management work is mostly documents that argue for something. A PRD, a roadmap, a set of OKRs, a launch plan. The failure mode is not bad writing. It is a document that reads well and rests on an assumption nobody tested.

Most AI writing help makes that worse, because a model asked to improve a document makes it more persuasive, not more true.

This plugin is built around the opposite instinct, and two of its commands are the reason to install it.

Which two phuryn/pm-skills attack your own work?

red-team-prd takes a PRD, roadmap, or strategy and attacks its load bearing assumptions, returning the cheapest way to test them. pre-mortem runs a risk analysis on a PRD, launch plan, or feature by asking what would have gone wrong.

Both are adversarial by design. You are not asking for a better draft, you are asking what is wrong with the one you have, which is the question that actually changes decisions.

If you install this plugin and only ever use these two, it has paid for itself.

What is the shipping packet for code you did not write?

A second cluster addresses a specific modern situation: you have a working application that an AI built, and now somebody has to review it.

• document-app reverse engineers the codebase into the system documents reviewers and auditors need
• derive-tests turns documented intent into a test coverage map, inventorying what tests exist today
• security-audit-static maps trust boundaries and cross references them against documented intent
• performance-audit-static finds N plus 1 queries, request waterfalls, and over fetching
• ship-check runs the whole sequence into a reviewer ready packet

The ordering is the useful part. document-app runs first because the audits cross reference documented intent, and you cannot check code against an intention nobody wrote down.

Which phuryn/pm-skills handle the routine work?

The rest is the ordinary PM calendar, and it is competently covered:

Command	When it fires
plan-okrs	brainstorming team OKRs against company objectives
sprint	planning a sprint, running a retro, or generating release notes
analyze-cohorts	retention curves, feature adoption, engagement trends
analyze-test	A/B results, significance, and a ship or stop call
write-query	SQL from natural language across BigQuery, PostgreSQL, MySQL
generate-data	realistic dummy datasets as CSV, JSON, SQL, or Python
meeting-notes	a transcript into decisions, action items, and follow ups

analyze-test is the one to watch. It validates sample size and significance before returning a ship, extend, or stop recommendation, which is the check most teams skip when a result looks good.

What does phuryn/pm-skills not do?

There are no agents and no MCP servers here. Every component is a skill or a command, which means nothing connects to a live data source. analyze-cohorts and write-query operate on data you bring, they do not go and fetch it.

That is a reasonable design for PM work, where the data usually arrives as an export. It does mean this pairs well with a plugin that does have a live connection rather than replacing one.
