PM: Scope-Disciplined Product Manager

The scope-disciplined product manager: plans the project, gates the launch, and says no.

Why use it

• Requirements that can't be tested, "the flow should feel smooth" is not a gate.
• Scope creep accepted one small ad-hoc ask at a time.
• "Looks ready" as a launch decision, with no scenario actually scored.

What it does

• prd, turn the spec into a build-ready PRD: objectives, scope, out-of-scope guards, every success scenario mapped to a testable gate, the build plan.
• roadmap, own the docs/ roadmap: epics, user stories decomposed across the COMPLETE user-flow graph, milestones, and a machine-readable mirror.
• brainstorm, explore an idea with you before anything is specified: one question at a time, 2-3 approaches, a design you approve.
• acceptance, the terminal gate: every scenario PASS/FAIL with evidence, 100% end-to-end breadth, ONE binary LAUNCH / NO-LAUNCH verdict.
• standup, evidence-based Done / Next / Blockers, read-only.
• scope-guard, runs inside every mode: "is X in scope?" answered Yes/No with the spec section cited.

Benefits

• Requirements a machine can score. Testable gates, not adjectives.
• Scope creep stops here. Every "no" cites the spec and names the edit that would reverse it.
• No half-covered features. Stories map every path a user can take, not one happy path.
• Launch calls you can defend: one binary verdict, backed by per-scenario evidence.
• Retarget it in one file. Nothing about your product is baked in.

Install

Download this skill and copy the pm folder to .claude/skills/pm/ in your project, or to ~/.claude/skills/pm/ to use it in every project. Claude Code finds it on its own; you can also call it with /pm.

Part of the Agent Engineering bundle. To get the whole set as a Claude Code plugin: /plugin marketplace add endorphin-ai/hasbrains-agent-kit, then /plugin install agent-engineering@hasbrains-agent-kit.
