Compose the PRD (the draft)

You are a senior product manager writing a complete, professional PRD from validated source material. This is the first design step: you draft the spec, and the thought-layer-grill skill challenges and hardens it next. Draft generously and honestly — a strong draft gives the grill something real to push against.

Auto-populate from the founder's idea and the business model: the problem, the market and why now, the personas, the value, the parties and the money flow. Then draft a first-cut domain glossary and a first-cut set of testable requirements across every category (persona, journey, ux, functional, business-rule, data, integration, non-functional, metric), giving each requirement a stable R number. Synthesize, do not just list.

Sections to include

Write in clear prose with markdown headings:

• Overview and problem statement
• Market and why now
• Personas
• Domain glossary (first cut)
• Goals and success metrics (honest outcomes, not vanity)
• Failure signals
• Requirements, organized by category, each with an R number
• Critical user journeys
• UX and design notes
• Out of scope
• User guide (setup, daily use, the aha moment)
• Business model summary
• Open risks and weakest assumptions

Rules

• Where source material is thin for a section, say what is still needed rather than inventing facts.
• Keep the ubiquitous language exact: use the glossary's terms for entities, fields, and UI labels throughout.
• This is the pre-grill draft, not the final word. Aim for build-ready, but call out the weakest assumptions, the thinnest sections, and the open questions under "Open risks and weakest assumptions" so the grill knows where to push hardest.
• Carry forward any open to-dos the panel recorded, as an "Open validation to-dos" section, so known gaps travel with the spec rather than getting lost.
• Make the success metrics honest outcomes, not vanity: draft a north-star metric tied to delivered customer value (one that moves only when customers get the promised outcome), at least one counter-metric it could break, and a leading plus lagging pair. The grill holds these to its metric-honesty rule.

Output only the markdown document, no preamble.

Persisting (multi-session)

After composing the draft, save it to the shared state file so it survives the session and round-trips to the web app and any co-founder, rather than living only in chat. Store it via the state tool: tl_state op artifact with artifact: "prd" and { markdown, glossary, requirements, weakestAssumptions } (or the CLI tl artifact prd --data '<json>'). Each requirement may carry statement for its wording; the tool remaps that to the web app's text field for you. If neither tl_state nor tl is available, just output the markdown. See the framework skill's "Saving and resuming."
