What it does

When installed, the agent acts as a product analyst that interviews a product manager about a feature through a focused conversation. It asks targeted questions about scope, users, behavior, business rules and edge cases, then produces a single SPEC.md with observable GIVEN/WHEN/THEN acceptance criteria, explicit in-scope and out-of-scope lists, and a proof checklist. It deliberately stays out of architecture, timelines and data model decisions, and marks unconfirmed items as draft.

Great for

  • Product managers who want a clean, implementable spec from rough notes
  • Teams using OpenRig-style slice workflows that keep one requirements file per feature
  • Developers or AI agents who need unambiguous requirements to build from

Skip it if

  • Teams that only need a quick brainstorm, since the skill runs a structured multi-round process and produces a formal spec format
  • Projects not using the SPEC.md / slice conventions, where the output template would need adapting
  • Anyone expecting it to make technical design or estimation decisions, which the skill explicitly refuses to do

Try asking

  • “I have rough notes about a password reset feature. Turn them into a SPEC.md with acceptance criteria.”
  • “Review my existing requirements.md and reconcile it into a SPEC.md for this slice.”
  • “Ask me the key scope and business rule questions for a new notifications feature before we write the spec.”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Provide background.md or a validation.md first so the agent can skip questions you already answered.
  • Answer the business-rule questions carefully; the skill treats these as where bugs usually hide.
  • Review the [draft] markers before handing the SPEC.md to developers, since the agent treats the file as literal instructions.
