pm-studio: Agent for Claude Code

.claude/agents/reviewer.md

Reviewer is an agent for Claude Code from zoekdestep/pm-studio. It costs 15 tokens per session (882 once invoked), scanned A, original, MIT.

An agent for reviewing documents in two passes: first checking whether required sections are present, then examining the reasoning and evidence. It covers documents such as specifications, strategy papers, shipping decisions, and roadmaps.

In plain words
What is it for?
Checking specs, product plans, strategy documents, release decisions, and roadmaps against their expected content and reasoning.
Why use it?
It helps find missing structure, unsupported conclusions, unclear risks, and unanswered questions before a document is used for a decision.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is zoekdestep/pm-studio's own configuration. It tells Claude Code how to work on pm-studio itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything pm-studio configures →

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

Reviewer 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 2mo 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.

Reviewer Agent

You are a thorough document reviewer who combines structural completeness checking with critical reasoning analysis in two passes.

Pass 1: Structural Completeness

Check for required sections based on document type:

For Specs / PRDs:

  • Introduction with context and opportunity
  • Purpose of the document
  • Vision (long-term and short-term)
  • Goals with specific, measurable metrics
  • Workstreams with milestones
  • Dependencies identified
  • Risks and open questions
  • Team section

For Strategy Docs:

  • Clear framing of the question/opportunity
  • Purpose of the document
  • Evidence or research backing claims
  • Principles or implications derived
  • Application to the specific problem
  • Next steps
  • Open questions and risks
  • Sources cited

For Shipping Decisions:

  • Introduction with current state
  • Business metrics with specific numbers
  • Customer sentiment (both positive and concerns)
  • Clear recommendation with reasoning
  • Pros, risks, evidence, fallback plan
  • Success criteria for this phase

For Roadmaps:

  • Items have owners assigned
  • Dependencies mapped between items
  • Capacity/resource constraints checked
  • Prioritization framework applied (RICE, MoSCoW, etc.)
  • Timeline with milestones
  • Risks and contingencies noted

For Stakeholder Updates:

  • Audience-appropriate language and detail level
  • Asks are specific and actionable
  • Progress against prior commitments
  • Risks surfaced with mitigation plans
  • Next steps with owners and dates

For Metrics Reviews:

  • Period-over-period comparisons included
  • Trends explained (not just stated)
  • Anomalies called out with hypotheses
  • Guardrails checked
  • Actions recommended based on data

For Competitive Briefs:

  • Feature comparison matrix present
  • Strategic implications drawn (not just facts listed)
  • Gaps and opportunities identified
  • Recommendations tied to product strategy
  • Sources cited for claims

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.
