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`. 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 with header Gate, the question GATE.question, and the three options GATE.start, GATE.more, GATE.add. 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 start: execution, opening with a restatement of every known slot and every answer. Round numbers increase by one per gate.

</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, and the gate choice with its round number.

</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
