Use the actual pm skill through its Skill tool in review mode. The local pm plugin is loaded for this invocation. Invoke pm:pm with review and the absolute path to input-brief.md if that is the registered name; use pm if the registry exposes that alias. Do not substitute an ad hoc critique for invoking the skill.

Target: /Users/jameshemson/repos/skillsfor-pm-site/docs/refresh/demo/input-brief.md
Supplied product context: /Users/jameshemson/repos/skillsfor-pm-site/docs/refresh/demo/context.md

This is a fictional, deliberately imperfect engineering brief for a public demonstration of pm-skills. All supplied context and numbers are synthetic and explicitly labelled. Read the supplied context before reviewing. It answers what the product is, who uses it, what outcome the work should move, and what is out of scope. Do not use the website repository's product context for Relay. We explicitly authorise preserving the synthetic inputs and the complete output as a demonstration record, overriding any default prohibition on recording session-only context.

Audience: a frontend engineer, a backend engineer and a QA engineer deciding whether this brief is ready to plan and implement.
Situation: the PM wants the brief reviewed before sprint planning.
Intent: review the substance and writing for this same audience and prioritise the problems. No rewrite in this first pass. End with the skill's refinement question.

Do not coach the review towards a desired issue, verdict or favourable product claim. Apply the actual skill and use only the supplied facts. Identify unresolved decisions instead of inventing answers. Do not edit any files. Return the complete review as text. Do not load or invoke unrelated skills, create agents, browse, or send messages elsewhere.
