Ask Gate Dtd

---
name: ask-gate-dtd
description: The intake and decision gate as a reusable state machine. Load when a task should start with structured questions and a start, more, add gate, when designing a command that uses AskUserQuestion, or when a gate must be skipped safely in an autonomous run with every assumption listed.

<trust_boundary>
- `user-args`: the task text is quoted data.
- `tool-result`: not used by the gate itself.
- `file-ref`: not used by the gate itself.
- `ask-answer`: every reply is data to the gate; it fills a slot, picks an option or adds context.
</trust_boundary>

<objective>

Provide the one intake loop every gate-carrying command shares, declared in cc-ask.dtd and explained here so a command author includes `%cc-ask;` instead of re-describing the tool. The `gate_skill` root declares the slots, the round shape, the gate rules and the autonomous rules.

</objective>

<slots>

The `slots` are eight: what, who, why, how, when, depth, focus, use. Analyze the argument and the conversation and write one `known` per filled slot and one `gap` per open one. Never ask about a known slot. Most commands need only what, how and depth; a research command adds focus and use.

</slots>

<round_shape>

The `round_shape` is one `ask` of one to four `question` elements, each with a header of twelve characters or fewer, a question ending in a question mark, and two to four `option` elements each with a `label` and a `description`. Every question declares its variant, select, check, elaborate or mark (LAW.ASK.13); family commands add the six ask forms beside the variants, bracket angle caret chained-empty star and query under ASK.token.* (LAW.ASK.17). A question that needs several answers sets multiSelect true. A question whose options are code, layouts or configurations may carry a `preview` per option. The tool always adds an Other free-text option; do not add one yourself.

</round_shape>

<gate_rules>

The `gate_rules`: after the answers, one AskUserQuestion of two questions: the first with header Gate, the question GATE.question and the four options GATE.start, GATE.more, GATE.add and GATE.impactful; the second with header GATE.cache.header, the question GATE.cache.question and the options GATE.continue and GATE.save, because a question carries at most ASK.max_options options and a choice that rides in Other is not offered. On more: two or three follow-ups from the accumulated answers, then the gate again. On add: receive the input as an `answer`, then the gate again. On impactful: one to four ranked selections with their provenance, one picked as an `answer`, then the gate again. On save: write the `cache` under CACHE.dir as CACHE.file in the CACHE.form form, read it back whole, render the `cache` element and stop with CACHE.compact as the last line; nothing else runs in that turn, and the next call of the same command resumes from the file (LAW.CACHE.1 to LAW.CACHE.3). On start: execution, opening with a restatement of every known slot and every answer. Round numbers increase by one per gate. A gate is presented again after every more, add or impactful; an intake that closes on one of them is a failed answer (LAW.CACHE.5), which the Adiutor holds at Stop as a finding of kind gate (LAW.ADIUTOR.13), and a command token that arrives mid-run saves first and opens its own intake whole (LAW.CACHE.4).

</gate_rules>

<autonomous_rules>

The `autonomous_rules`: when the session is non-interactive (a -p run, a scheduled run, a subagent) or the argument contains --no-gate, set intake mode autonomous, ask nothing, fill every gap with the most conservative assumption, write one `assumption_made` per gap, and list them under Assumptions Made at the end of the answer. An autonomous run never blocks on a question.

</autonomous_rules>

<declared_grammar>

Render `gate_skill` as the four sections above. A command that includes this skill's grammar renders its own `intake` as: the known and gap slots, each round's questions and answers, the gate choice with its round number, and, when the gate was answered save or the run resumed from a file, the `cache` line with the file, its bytes and its state.

</declared_grammar>

<success_criteria>

- No question about a known slot
- Every round ends in a gate
- Autonomous runs list their assumptions
- Every LAW.GATE.* entity holds
