Intake — only what this product needs, never invented

The house harness (stack, coding, testing, security, CI, agent protocol) is already decided and inherited. This interview covers only the product: why it exists, who uses it, its domain, its hard limits and its environments. Target: 15–25 questions, fewer when documents exist.

Read before starting: references/question-bank.md and references/context-format.md.

1. Harvest before asking

1. Ask once what already exists in writing and where (briefs, notes, decks, screenshots, a repo, links). List what you found and confirm the list before reading.
2. Read each source against the question bank. Pre-fill every question it answers, citing the source id (S1, S2…). A document that is undated, a draft, or contradicts another source is to confirm, not answered.
3. Existing repo: read the README, manifests, CI and top-level folders (structure and commands, not logic). What you derive is inferred until the user confirms it.
4. Show the delta before any question:

   Sources: 3 (S1–S3) · Answered by documents: 11/26 · To confirm: 4 · To ask: 11

2. Interview the delta

• At most 4 questions per turn, with the multiple-choice tool when the answer space is known, always with a free-text path and an "I don't know yet" option that records a gap.
• Accept only measurable answers: a number, a name, a date, a regulation, a concrete example. Re-probe a vague one once — "how would we know it holds?", "what number?", "what happens if it doesn't?" — then record a gap instead of writing the vague version.
• High-signal probes: the last time this problem hurt (a concrete story), what they use today and why it fails, what would make them abandon the product, the rule that must never break.
• Separate wish from requirement: "is it required to launch, or where you want to get to?" Wishes go to the PRD's later scope, not to constraints.
• Three unanswered in a row in one block → stop the block, record gaps with the right owner, move on.

3. Write docs/context

Write the five files exactly as references/context-format.md shows: product.md, domain.md, constraints.md, environments.md, gaps.md.

• Never invent. No source, no fact: write [GAP-nnn] inline and add the row to gaps.md (file, what's missing, owner, exact question, blocking yes/no).
• Every fact carries its source id; inferred facts are marked (inferred, S3).
• Constraints are written as [MUST] / [MUST NOT] with something measurable; if breaking it has no named consequence, it is not a constraint — move it to the PRD.
• Rules that must never break (D03–D03d) become invariants in domain.md: [INV-nnn], the rule, class: <class> and the source. Ask how it breaks to pick the class; two ways → two invariants. Ids never change or get reused. Money, one-time side effects, limits and other people's data are where the worst bugs live: don't close the domain block without asking.
• No vague phrases ("robust", "user-friendly", "best practices"…) — python3 .keelokit/bin/doctor.py rejects them.
• No secrets, no personal data of real people; accounts are named by owner, never with values.

4. Keep the profile true

If the project has .keelokit/profile.toml, update its traits from what the context now says: personal-data when it stores anything that identifies a person, payments when money moves, i18n for more than one language, developer-facing when its users are developers. A new feature that needs something new (an API, a database, a mobile app, hosting) adds it too — and say so to the user: it changes which rules apply and what the bug bash hunts.

5. Check and hand back

1. If the project has .keelokit/bin/doctor.py, run it and fix every docs/context error.
2. For a deep review, delegate to the context-auditor agent (it didn't write the context, so it catches invention and vagueness the author misses).
3. Report: sources used, questions asked, gaps open by owner (blocking first), and the questions to ask next.

Resumable: the files on disk are the state. On a new session, read docs/context/ and gaps.md, say what is covered and continue with the open gaps.
