Structured Choices

Install

Run when the user asks to install or set up structured-choices for this repo — including right after npx skills add. Do not gate; write agent config.

1. Explore

• AGENTS.md and CLAUDE.md at repo root — which exists? Is ## User gates or ### User gates already present?
• ## Agent skills section — if present, prefer the subsection block (see agents-block.md).

2. Pick target file

• If CLAUDE.md exists, edit it.
• Else if AGENTS.md exists, edit it.
• If neither exists, create AGENTS.md unless the user names another file.

Never create AGENTS.md when CLAUDE.md already exists (or vice versa).

3. Choose block

From agents-block.md:

• ## Agent skills present → add or update ### User gates (short block).
• Otherwise → add or update ## User gates (full block).

Update in place when a User gates section already exists; do not append a duplicate.

4. Confirm and write

Show the section draft. After confirmation, write to the target file. Report which file was updated.

Done when: User gates section is present and matches the chosen block from agents-block.md.

Gates (runtime)

At each gate — a fork, confirmation, or permission pause before you proceed — the choices reach the user as buttons they click, through the host's question tool.

When to gate

• Named-option forks (schema, library, strategy, path among candidates)
• Destructive or irreversible actions (delete, overwrite, force push)
• Permission pauses (install packages/skills, modify config)
• Ambiguous requirements the request or codebase cannot resolve

Skip the gate when only one sensible path exists, the question is genuinely open-ended ("What should I call you?"), or no user is available to answer (a CI or scheduled run) — pick a documented default and state the assumption in one line.

The test there is whether a user is present, not which tools you can see. A gate you tried and could not render is the failed call below, not a skip.

Options already written as a list

Most skills predate this one, so a skill you are running will often spell its choices out as a bulleted list, a blockquoted question, or a "then ask the user" line — sometimes phrased as though you were about to type it into chat.

Read that as option data for a call: it describes the fork rather than drafting your message. Take one option per entry, an id from the entry's key or a slug of its label, and fold each entry's explanation into its label. A wording like "so they can accept it in a word" describes the click, not a request for prose.

A skill that never mentions gates still gets one. Nothing needs to opt in.

Gate rules

• One gate per assistant message — halt until the user responds. A gate may contain multiple questions when another skill composes it (e.g. grilling rounds).
• Two or more fixed options — a real fork, carrying the alternatives the user would actually weigh.
• Record by id — proceed using the option id, not paraphrased label text.
• Recommended first — list the suggested option first and suffix its label with (Recommended).
• One rendering per gate — the call carries the options; the message beside it says only why you are asking.

Candidate count: 1 match → inline one-line confirm; 2+ matches → full gate.

Emit the gate

Call the question tool. In Cursor it is AskQuestion, built in: invoke it directly, the way you invoke Read or Grep.

The call is the check. Make it your first move. Its result is the only evidence about the tool that exists — a reading of your tool list is not evidence, and neither is a conclusion about which host you are on.

{
  "questions": [
    {
      "id": "issue-tracker",
      "prompt": "Where should issues live for this repo?",
      "options": [
        { "id": "github", "label": "GitHub — the remote already points there (Recommended)" },
        { "id": "local-md", "label": "Local markdown — files under .scratch/" }
      ]
    }
  ]
}

An option carries id and label; explanatory detail rides inside the label. Halt after the call and let the user answer.

More shapes — confirm, multi-select, grilling rounds: payload-examples.md.

When the call comes back an error

Then, and only then, other-hosts.md carries the alternatives: the field mapping for a question tool under another name, a JSON contract for hosts that parse one, and the prose form for a host with no question tool at all.

Whichever form you land on, open with the question itself. Your tool situation is yours to handle, not the user's to read about.

Carve-outs

• Grilling rounds — grilling composes this skill: one multi-question gate per round (native tool questions array or equivalent). Not a prose-list exception.
• Async questionnaires for third parties — use to-questionnaire, not this skill.
