spawn-unbriefed
An advisory by default: it explains, and blocks nothing, on a subagent spawned before the multi-agent skill loaded.
What it catches
A subagent spawned before the multi-agent skill loaded.
Why
Four decisions a spawn cannot be corrected for later are made before the child starts: which worktree it is cut from, which lease grades its writes, which model it runs, and that git stays with the orchestrator. The magus-multi-agent skill carries all four. A skill nobody is required to read is a skill nobody reads, so the spawn waits on the load instead of trusting it. It grades the session, never the prompt: it asks whether a marker file exists, so a handed-over prompt that merely mentions a denied command is untouched. Load Skill(magus-multi-agent) once and every later spawn in the session passes.
Default and override
By default this rule takes the decision advise. A workspace sets it by name, in its root
magusfile, to deny, advise or off:
magus\guard.builtins({"spawn-unbriefed": "deny"})
A loosening takes effect once it is committed; a tightening applies at once.
Seeing it
A verdict names its rule in brackets, which is how you got here:
advise [spawn-unbriefed]: ...
magus describe rule spawn-unbriefed prints the same entry at a terminal, and
magus describe rules lists every rule this workspace enforces.
