Generates a single-page PRD in HTML when you mention "spec," "PRD," or "feature brief" in your prompt. You get a clean layout with problem statement, success metrics table, user stories in as-a/I-want/so-that format, a milestone tracker, and an open questions section with assignee chips. It reads your DESIGN.md first to stay consistent with your system, then structures everything into semantic HTML with minimal inline styling. Nice for when you need to document a feature without wrestling with Google Docs templates or Notion blocks. Ships as a single artifact you can preview immediately.

Produce a one-page product spec / PRD.

Workflow

  2. Identify the feature + audience from the brief.
  3. Layout:
    • Header strip: title, status pill (Draft / Review / Approved), date, owner.
    • Three-line summary at the top — what, who, why now.
    • "Problem" panel with one paragraph and a quote from a customer or internal partner.
    • "Goals & non-goals" two-column block.
    • "Success metrics" table with metric / target / measurement.
    • "User stories" list with as-a / I-want / so-that format.
    • "Scope" milestone tracker (3–4 phases).
    • "Open questions" with assignee chips.
  4. One inline <style>, semantic HTML, accent used twice max.
