utility-pm-critic

utility-pm-critic is a skill for Claude Code from product-on-purpose/pm-skills. It costs 75 tokens per session (1,455 once invoked), scanned A, original, Apache-2.0.

A review tool for product-management documents such as product requirements documents, goals, user profiles, and meeting summaries. It checks them from a deliberately skeptical angle and reports issues by severity with suggested fixes.

In plain words
What is it for?
Use it to stress-test product documents before sharing or approving them. It also helps review interview summaries, hypotheses, retrospectives, and similar planning materials.
Why use it?
It helps find unclear assumptions, missing details, and weak reasoning before a document guides a team. This reduces the chance of shipping a flawed plan.

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

utility-pm-critic 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 9d 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.

PM Critic (Dispatch Skill)

This skill is a cross-client dispatch wrapper for the pm-critic sub-agent. It exists so that users on non-Claude clients can run adversarial review with the same intent as Claude Code users, without depending on native plugin sub-agent infrastructure.

Per master plan D11 (amended) + D30, sub-agents are a Claude Code plugin feature. Non-Claude clients (Codex CLI, Cursor, Windsurf, Copilot, Gemini CLI) cannot natively load agents/pm-critic.md. This skill bridges the gap.

When to Use

  • You want adversarial review of a PM artifact (PRD, OKR set, persona, lean canvas, meeting recap, interview synthesis, problem statement, hypothesis, edge case catalog, retrospective, etc.)
  • You are running on a non-Claude AI client and the pm-critic sub-agent is not natively available
  • You are running on Claude Code and prefer skill-invocation semantics over sub-agent semantics (e.g., for consistency across a multi-step workflow that mixes skills and sub-agent intents)

When NOT to Use

  • You want a structural lint / repo-level audit -> use utility-pm-skill-auditor (audits skills + repo state) instead
  • You want to author an artifact (this skill only reviews) -> use the appropriate phase skill (deliver-prd, foundation-okr-writer, etc.)
  • You want code review -> use a code-review-specific tool (this skill is for PM artifacts)
  • You want to enforce style rules like em-dash sweep -> that is pm-release-conductor's G0 gate, not this skill

Instructions

Runtime detection step. Determine which AI client is invoking this skill.

If you are running in Claude Code with the pm-skills plugin installed

Invoke @agent-pm-skills:pm-critic on the target artifact. Pass the artifact path as argument (or the most recent artifact in session context if no argument is provided). Return the sub-agent's findings to the user. No further action needed from this skill - the sub-agent handles the review natively in its own context window.

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.
