The orchestration skill description only advertised coordinator work, so a dispatched worker never loaded it and built its heartbeat loop from the preamble alone. Neither the preamble nor the guide said to stop a background heartbeat loop before worker_done, so the loop outlived the task. Add worker-role triggers (heartbeats, ask, worker_done) to the description and stub, and tell workers in the preamble and guide to restart an expired heartbeat loop mid-task and stop it before worker_done. Fixes #26605

Orca Orchestration
This file is a discovery stub, not the usage guide. The full, version-matched Orca
orchestration reference is served by the orca binary itself — kept out of this file on
purpose so it can never drift from the binary that will actually run your commands.
Engage Orca orchestration whenever you need structured multi-agent coordination: threaded
messages, blocking ask/reply flows, task dispatch, worker_done/escalation waits, task DAGs,
decision gates, coordinator loops, or decomposing work across agents. Engage it as well
when you are a dispatched worker sending heartbeats, ask questions, or worker_done. Use
the orca-cli skill instead for full ownership handoffs ("hand off", "handoff", "handover",
"give this to another agent", "another worktree") when the user did not ask to supervise,
monitor, wait for results, or coordinate a DAG — and for ordinary terminal control, shell
commands, worktree management, and the built-in browser. Coordination requires real Orca
runtime state; never substitute a non-Orca subagent tool.
Load the version-matched guide before running Orca commands
ORCA skills get orchestration
That prints the compact, version-matched guide for the exact binary that will handle your
next commands. It covers the normal local coordinator loop and dispatched-worker
obligations. For a conditional action gate such as remote placement, uncertain release
recovery, or expanded DAG work, load only the reference that gate names with
ORCA skills get orchestration --reference references/<file>.md
(--references lists the names). If that binary rejects --reference, run
ORCA skills get orchestration --full and read the named bundled reference before acting.
