Starting a new project

The workspace is empty: no code, no decisions. Turn the user's idea into one clear, living product document — goal-and-requirements.md. Later features, behavior changes, and bug fixes go through brainstorming.

Hold the writing-specs bar. Read that concept skill before saving anything — it carries the short / honest / on-rails rules and the goal-doc shape every section you save must meet.

Method

1. Build on what's already said. Never re-ask what the request already told you.
2. Infer, then confirm — propose a concrete draft and let the user correct it; a suggestion beats an open question. Compose ask_user_question rounds per the asking-user-questions concept skill (read it before the first round — it carries the round, option, confirmation, and degradation norms).
3. Smallest useful first build. It is smaller than the user expects; every capability in it must justify itself. Ideas cut from it are handed back to the user, not saved (see writing-specs).
4. Save incrementally. Create the file as soon as the first section is settled, then add each confirmed section in template order. Don't batch; don't invent unconfirmed content.
5. A skipped question is not a blocker — proceed on the current model and note real gaps inline.

Working model (infer from the request; never ask these directly)

audience:   personal | public | both        domain: what space this is in
tech:       stack mentioned, or null         scope:  small | large
depth:      light | standard | full          creator_is_user: does the maker use it?

depth scales the document: light = a one-liner idea → a few lines; full = named competitors / multiple user types → a full PRD. It can only grow during the conversation, never shrink.

Fast path — pre-filled brief

If the request already reads like a spec (several headings or a multi-section brief), parse it, treat those sections as confirmed, save them immediately, and only pursue what's genuinely missing and required by depth. Don't ask the user to confirm what they already wrote. Save in the goal-doc shape, not the brief's: a version or roadmap split (MVP / v1 / v2 / later) becomes Capabilities for what is in scope and Non-Goals only for what the brief rules out by decision; the rest goes back to the user unsaved (writing-specs). The one always-offered extra is alternatives research (below).

Flow

1. Orient — one line: "Let's nail the goal and scope, then I'll save it as goal-and-requirements.md."
2. Overview — infer it (depth-sized: a sentence → a paragraph naming what it replaces) and confirm.
3. Problem — one tailored question referencing the domain (never generic); turn the answer into a statement (who / what they do today / the specific breakdown) and confirm. Skip if the Overview already implies it.
4. Route from the model — don't ask "who's this for" unless genuinely ambiguous: personal / first-person pain / depth=light → Personal spec; public / named users / depth=full → PRD.
5. Elicit the branch's sections (below), inferring and confirming each, saving as you go.
6. Research alternatives (always offered, never forced): web_search + fetch_content for the closest open-source projects / products, then offer to add an Alternatives Considered section (name, one-line gap, URL). On a pre-filled brief, ask permission first.
7. Review the full draft in plain markdown and confirm, then finalize.

Personal spec (sections)

# Title + one-line tagline · Overview · Problem · Capabilities (only what the tool is useless without) · Tech Notes (the stack, once chosen).

PRD (sections)

# Title + tagline · Overview · Problem Statement · Target Users (roles, not demographics) · Jobs to Be Done ("When [situation], I want [motivation], so I can [outcome]") · Key User Story (one concrete scenario) · Goals (verb-first, measurable) · Non-Goals · Success Metrics / Success Conditions · Capabilities (each justified against a Goal or success condition) · Non-Functional Requirements (only if they exist) · Technology (Aspect | Choice | Rationale).

Skip any section the model already answers or that depth doesn't warrant (light → skip Goals/NFRs, binary Success Conditions instead of metrics). Reject vague goals inline: "'Better UX' isn't a goal — 'first result in under 30s' is."

Saving

• spec_create once, path: "goal-and-requirements.md", a slug id, type: "goal-and-requirements", title, status: "draft"; replace the scaffold with the chosen template + the sections settled so far.
• edit to add each confirmed section in template order.
• spec_update status: draft → active once the user approves the reviewed draft.

Next

State plainly that the spec is saved and evolves with the project. Suggest the natural next step — sketch architecture.md, then build each feature through brainstorming. There is no board/ticket hand-off — say it and stop: this workflow ends here.
