-Trigger (any match):
-- User explicitly asks to consult one of them (e.g. "ask codex ...", "let gemini ...")
-- User uses an assistant prefix (see table)

-Fast path (minimize latency):
-- If the user message starts with a prefix: treat the rest as the question and dispatch immediately.
-- If the user message is only the prefix (no question): ask a 1-line clarification for what to send.

-Actions:
-- Ask a question (default) -> ``Bash(`$env:CCB_CALLER='claude'; ask <provider> <<'EOF' ... EOF)``, tell user "PROVIDER processing...", then END your turn
-- Check connectivity -> run ``ping <provider>``
-- Use "show previous reply" commands ONLY if the user explicitly requests them
-
-Important restrictions:
-- After starting a background ask, do NOT poll for results; wait for ``bash-notification``
-- Do NOT use ``pend`` unless the user explicitly requests
