Mux

mux

This skill is a package-owned trigger alias for ac-workflow-mux. It is not an independent workflow definition.

Delegate workflow semantics to ../ac-workflow-mux/SKILL.md and runtime semantics to ../../extensions/pimux/docs/.

Mandatory trigger behavior

If the user explicitly triggers mux, the parent must actually run through pimux.

Required sequence:

1. after spawn, do not poll pimux or use Bash sleep/wait loops; wait for delivered child bridge activity
2. treat the authoritative pimux extension as the fail-closed parent control-plane lock
3. prepare bounded handoff from the user request only
4. spawn the authoritative pimux child before substantive analysis
5. keep the parent control-plane only; use AskUserQuestion only for explicit user clarification
6. after spawn, run notify-first rather than poll-first: do not call status, capture, tree, list, or open on the happy path
7. after a child progress report, use at most one send_message if input is needed, then wait again
8. use status / capture / tree / list / open only for explicit live inspection, suspected stall/protocol violation/failure, or the inactivity watchdog
9. after terminal settlement, do one final pimux status verification and then advance

Do not satisfy mux requests by directly doing domain work in the parent. Do not use parent-side Read, Bash, or repo inspection to figure out the task before spawn. Do not poll pimux or use Bash sleep/wait loops; wait for delivered child activity, and treat status / capture / tree / list / open as recovery-only.
