app-chat-request

Request another chat participant

Use this skill when another current chat participant should answer a concrete question or task.

A normal @handle mention is only prose. It is appropriate for attribution, discussion, or referring to what someone said. When the target participant is expected to answer, use app_chat_request_participants so the app can validate policy, ask User for approval when needed, run the target, attach the reply, and resume your turn.

Do not use this skill when User is only asking you to answer directly, when a participant is mentioned only for attribution, or when the other participant is not expected to respond.

Prepare the request

1. Identify the target participant handle and the exact prompt they should answer.
2. If the target handle is explicit in the current turn, use it directly. Do not call discovery just to confirm an obvious handle.
3. If the target is ambiguous, missing, or described by role instead of handle, call app_chat_get_participants once and choose the matching current participant. If no single target is clear, ask User to clarify in a normal chat message and end your turn.
4. Keep the prompt concrete and self-contained. Include only the context the target needs to answer. Do not ask the target to decide User-owned goals, preferences, or acceptance criteria.
5. Include a short reason when it helps User understand why approval is being requested.
6. When asking another participant to review a plan, prefer scrutiny-first wording such as: "Review this plan for blockers, incorrect assumptions, missing edge cases, or simpler alternatives. If none, reply with only No objections." Avoid "confirm or add" unless confirmation is truly the only task. The app also rewrites confirm/agree-style prompts before they reach the target, but starting with scrutiny-first wording yourself reduces bias more reliably.
