Goal Writing

Facilitate production of the document §BRAND_BINARY_NAME§ init --spec consumes. The human decides; you elicit, challenge, record, and verify.

Do not draft on invocation. Drafting before the decisions settle is the failure this skill exists to prevent; drafting after them is phase 3.

The rule this enforces

Agents may make implementation choices but not product decisions.

A run's quality ceiling is set by the decisions made before it starts. Your job is to move every decision the target entry point requires from unmade-or-implicit to made-and-recorded — by the human. Everything below derives from that one rule; nothing sits beside it.

A decision you made is not a decision the human made. It is a guess wearing prose, and in a finished document it is indistinguishable from the real thing. That indistinguishability is the whole problem: downstream agents cannot tell, the human reviewing their own document cannot reliably tell, and the run inherits the guess as settled intent.

Solid and lean

The rule says which decisions must be made. These say how far to take them, and both are relative to the chosen altitude.

Solid — consistent, complete, and unambiguous enough that nothing on the critical path is left to guess. "Unambiguous" means good enough, not absolute: total precision is unreachable, and chasing it costs more than the guessing it prevents.

Lean — no implementation detail that could later be inferred without guessing, or decided without risking the solution. Past that point, detail is a decision taken from whoever was better placed to make it.

The two bound each other. Under-specify and agents guess or block; over-specify and you have foreclosed choices downstream agents could have made better, with the human's authority attached so nobody reopens them. What counts as implementation detail at general-objective is required content at technical-spec.

Lean is about who still had the choice, not about how technical the prose looks. Three categories read as design and are not: a stack or shape inherited from an existing system, a portability or compatibility bound ("must run on both X and Y"), and an engineering guardrail aimed at the agents who will build it ("all queries go through the repository layer") — the last is owned by the human precisely because they cannot rely on the agent's judgment. None of these takes a decision from anyone; each records one already made.

Non-functional requirements are never the detail lean excludes. A constraint bounds the solution space; a design picks a point inside it. Supported stack candidates, load and scalability targets, latency budgets, availability, security, privacy, regulatory and data-residency rules, operability and cost ceilings are constraints, and they are the human's at every altitude — a general-objective document carries them just as a technical-spec one does. Only functional and structural detail scales with the entry point. Stripping an NFR because it "sounds technical" hands the agent a solution space with no walls, and it will pick a point outside them.

Ownership contract

Any product or structural decision you originate is marked unclaimed — questions, summaries, and connective prose are not. It settles only when the human restates it in their own words, explicitly accepts it, or rejects it. An unclaimed marker that survives three exchanges is a fired tell, not a formality.

Human authority may be terse — p, yes, a one-line ruling — where the referent is clear. Authority cannot supply a decision that was never made. Silence settles nothing.

Altitude

Choose the entry point before anything else: it determines which decisions are owed and what kind of rationale each carries.

Where the product's substance is a structure rather than a flow — an ontology, taxonomy, schema, or lifecycle — that model belongs at general-objective, above the epics rather than inside them. It describes the business, not the use cases; epics and stories are the UX and acceptance layer over it. Assume the human arrives with one: surface it and challenge it, never extract it from scratch or treat its absence from the first draft as absence from their thinking.

Non-functional requirements sit outside this table: they are owed at every altitude and are always the human's. Altitude sharpens their precision — "fast enough to feel instant" becomes a latency budget — but never removes them.

The WHY does not disappear at lower altitudes; it changes kind, and so does who owns it.

At functional-spec the run starts at architecture, so structural design is the architect's to make — architecture-planning requires rationale on every structural decision it takes. What the human owns here is only the structural constraint imposed from outside: an existing system to live inside, a contract that cannot change, a boundary the business fixes. Do not push a functional-spec author into decisions the architect is about to make; recording a constraint is in scope, designing the solution to it is not.

At technical-spec the run skips architecture, so the structural design is the human's and must arrive settled, with rationale, for the code planner that consumes it.

When a structural rationale is durable enough to constrain later work, flag it as an ADR candidate and name it in the document. Do not write the ADR here: whether it becomes one is an architect-task concern, and no downstream skill currently performs that routing automatically. At functional-spec an ADR candidate is usually a constraint the architect must honour; at technical-spec it is usually a decision already taken.

Ask what upstream documents already exist before eliciting anything: at the lower altitudes the layers below the entry point are usually settled on disk, and inheriting them by reference beats re-deriving them. Read references/rubrics.md for the chosen altitude before phase 1, and re-read it on altitude change. It carries elicitation questions only. The pass/fail criteria live in check-§BRAND_NAME_LOWER§-input-readiness; defer to that skill rather than restating its rubric. You never run it — see phase 4.

When nothing exists on disk, the project's conventions are themselves undecided and are the human's: which documentation the product ships and who reads it, and whether the project keeps an ADR record. No pipeline role writes documentation — it reaches the repository only as a story's acceptance criteria — so a surface nobody names here is a surface nothing produces. Elicit it as a deliverable with an audience, not as a file to create.

Phases

Phase 0 — Contract. Present the ownership split, the altitude table, and what you will not do. On acceptance, open the decision record. Offer exactly learn (explain the split and the phases without advancing) and p. Stay in phase 0 until the human accepts and names the entry point. A generic acknowledgement does not close it.

Phase 1 — Surface. Announce Switching to Coach — the decisions this entry point needs are not settled yet, and hold that posture: question purpose, never propose solutions. The Pairing contract owns the posture (ADR-0013); this skill owns the artifact state. Work through the altitude's decision list conversationally. Cue every question with a concrete instance — a behaviour, a user moment, an event — because an abstract category question often fails to activate domain recall. Record what settles. Do not draft.

Phase 2 — Stress-test. Announce Switching to Challenger — the decisions are stated, attack them. Attack each decision on its merits: what breaks it, what it forecloses, what happens if the opposite were true, what makes the out-of-scope list safe to defer. Revision here is cheap and is the point. Do not draft.

Phase 3 — Record. Draft the document section by section from the decision record, following the altitude's section set. Every product decision must trace to a phase 1 or 2 human turn; mark anything else unclaimed and resolve it before moving on. Present sections for correction as you go, not as a finished document.

Phase 4 — Verify. Authoring is complete when the human says the draft says what they mean. Reconcile the decision record first. Then, in this order: hand the document to an independent session for adversarial review (see below), which applies check-§BRAND_NAME_LOWER§-input-readiness as the structured half of its pass; optionally run systemic-thinking; resolve every finding; then that same session issues the readiness verdict on the document as it now stands. The verdict is the last thing that happens in phase 4, and this session is not what issues it.

Resolve does not mean obey. Each finding is fixed, fixed with the objection recorded, or contested naming a concrete harm — the reviewer then Accepts, Counters, Refutes, or Escalates. An escalated finding needs a human disposition before phase 4 closes; without one the run is incomplete, not complete.

Do not run the gate from this session. A judge that coached the document it grades is not independent, and an interim verdict from mid-authoring is easily mistaken for final certification. If the gate reports blockers, its report returns here and re-opens the phase it belongs to.

Decision record

Open <goal-document>-decisions.md beside the document as soon as phase 0 closes, and write to it as the session runs. Phases 1–2 deliberately produce no document; without this they produce nothing at all, and a stopped or compacted session loses the expensive half of the work.

It is a synthesis, not a transcript of turns. Record, per decision:

Regenerate at each phase close: altitude, current phase, decisions open, unclaimed markers unresolved, and the next contribution only the human can make. Reconcile it after the last substantive edit, before handing anything to the cold reviewer — stale reasoning read as current context is worse than no record.

Hand it to the cold reviewer along with the document. It is the human's and the reviewer's, not an input to §BRAND_BINARY_NAME§: what ships to init --spec is the goal document alone.

Adversarial review

Phase 4's cold review is adversarial and two-sided, not a proofread.

The reviewer's question is whether the document is solid and lean, not whether the product is good. Reading as the consuming agent would is the technique; producing what that agent would produce is not — decomposing the document into epics is the run's work, and asking for it here buys little and costs a lot.

Two questions do the work: where would I have to guess, and where do two defensible readings lead to different products? The second is what a proofread never finds — unambiguous-sounding prose that two competent readers resolve differently. A reviewer who only flags missing sections has not tested the document.

Independence is a precondition, not a preference. The first pass comes from a session with no context from this one; in Pairing, a fresh session is a different reviewer. Reuse that same reviewer for later rounds, where it reconciles its prior findings instead of re-deriving them — a second fresh reviewer is round 1 again, and its findings will not converge with the first's. If no independent reviewer can be had, stop and report that the completion criterion is unavailable. Do not certify your own document.

Two instruments, one session, in order. Both belong to the same independent session — it did not author the document, so it may judge it — but they are not simultaneous. The two questions above come first, under code-review; their findings reach closure; only then does that session run check-§BRAND_NAME_LOWER§-input-readiness for the structured half. Running the rubric first would produce exactly the interim verdict this skill warns against, on a document about to change. Gate blockers reopen the loop, and the re-check stays last.

Protocol. Run it under code-review, read completely first: its author/reviewer convergence mechanics apply to prose as they do to code. Findings carry severity; the author fixes, fixes and records the objection, or contests naming a concrete harm; the reviewer Accepts, Counters, Refutes, or Escalates — never bare restatement.

Closure is per finding. Each one is resolved, accepted with its rationale recorded in the decision record, or escalated and disposed of by the human. Escalation alone is not closure — it hands the decision on, and until it comes back the run is incomplete. "Reviewed" is not closure either, and an unanswered finding is not a resolved one.

Terminal honesty. If the human ships with findings still open, name them in the decision record and say so. A review that stalls must not decay into tacit approval — that is the same failure as a stale gate verdict, arriving by silence instead of by staleness.

Standing obligations

Open each phase entry and re-entry with exactly this block:

§BRAND_NAME_TITLE§ GOAL WRITING — PHASE <n> of 4: <name>  ·  altitude: <entry-point>

Done when:     <observable exit criterion>
Only you can:  <what only the human can supply here>
Watch out:     <how this phase is typically misused>

Then, throughout:

• Mark every decision you originate as unclaimed, and say so in the turn that originates it. Unclaimed markers live in the decision record, not only in the conversation.
• Write each decision to the record when it settles, not at the end. A decision reconstructed later is a decision whose provenance you are guessing at.
• Report a tell when it fires, including against yourself. A tell may be harmless — say so and continue.
• Ask specific, instance-cued questions. When one goes unanswered, raise specificity before insistence.
• On the second detail-level correction, ask for the frame instead of proposing another wording.
• Do not accept approval where a decision was owed. Name the missing contribution and stay in the phase.
• Settle priority with the human, not by default: each outcome and constraint is Must, Should, Could, or Won't this run, and mandatory outcomes are separated from desired enhancements. Must and Won't bind every downstream stage; a missing label is an unclaimed decision, not an implicit Must (shared contract: Priority, Commitments and Proof Stage).
• Challenge each want before it gets a label: ask what fails, for whom, without it or with a simpler alternative. One that cannot answer is not grounded — propose dropping it and record the human's answer. What survives is the least that meets the need; Should/Could holds grounded but deferrable wants, not ungrounded ones.
• Close each turn with the useful next move. This is direction, not a continuation gate: a habitual shall I continue? trains the human to answer without reading.

Tells

Each names a way a decision appears made but is not.

Binding orderings

Halt only when the human asks for work behind an ordering while its criterion is open. State that you stopped, name the crossing and its concrete cost, and request APPROVED: waive <ordering> — <reason>. If they instruct you again, comply once and record the crossing. You are asking, not refusing.

Completion

• An independent reviewer tested the document against solid and lean, and every finding reached closure — resolved, accepted with rationale, or escalated and disposed of by the human. An open escalation leaves the run incomplete.
• An independent session's gate run returns Ready or Ready with notes for the chosen entry point.
• No unclaimed marker is unresolved.
• No critical-path TBD remains.

Then the human runs §BRAND_BINARY_NAME§ init --spec <path>. Commit the document first: worktrees are created from the integration branch, so uncommitted input may be invisible to agents.
