This skill is a router. The pipeline runs inside the agentmaster-plan
custom agent, which carries the frontier model pin and the agent/todo-only
tool restriction that enforces the cost boundary.
Invoke the agentmaster-plan custom agent now, passing the user's task and
any --lite or --headless flags verbatim. Do not run the pipeline inline
in this session — the cost boundary depends on the coordinator's restricted
toolset. If the custom agent is not available, tell the user to run
python install.py install --target copilot from the agentmaster bundle.
