ce-prototype
Build a throwaway prototype to answer how something should work, feel, or read. Use when committing the wrong answer would be expensive to unravel and a cheap sketch cannot settle it. Not a rough visual probe during brainstorming, not for deciding what to build, not polishing a feature that already works, not implementing the real thing.

What this skill does
Prototype Build a throwaway prototype at the fidelity that can answer this question, before committing an approach later work will treat as given. Then apply the decisions or hand off. Do not fake the dimension being tested. Modality, fidelity, and medium all follow from that one rule. A question about how a flow or state model behaves is settled by driving it, so a screen that only looks like the product does not answer it. A question about how a layout or a mark reads is settled by seeing it at real finish, so a thin sketch does not answer it either. The user's own perception settles the question, never your judgment of the artifact. Result: the user decided how the product should work or feel against a prototype that did not fake what they were deciding. Next consumer: an existing markdown Product Contract, or ce-brainstorm / ce-plan with this session as the seed. Done: the user settled the questions that needed an artifact, or they apply and continue into brainstorm or plan. Their choice is the settlement, not a direction you inferred. Not: a decision a cheap sketch settles, polish, or shipping the prototype as a final product. If there is no person to experience the prototype — LFG, mode:pipeline, or any unattended run — stop. Do not start a preview or invent how it should feel. Return that this skill needs a human. User-runnable invocation rendering. The attended re-run in that refusal and the next-skill recommendation when the user applies print invocation syntax. Default to /ce-prototype, /ce-brainstorm, and /ce-plan; use $ce-prototype, $ce-brainstorm, and $ce-plan only on Codex or a host that documents dollar-prefixed skill invocation. Render only the invocation as inline code; output one form only. Scope the question Read references/scoping.md before you ask the user anything or touch the repo. That load is not optional. It owns how the question arrives and the scoped repo read of what the question touches — do not scan the tree. …
