fm

When the user invokes $fm <model-id>, run this skill's scripts/emit.sh using the
absolute path shown in this skill's <path> (its directory + /scripts/emit.sh).
Pass the model id as arguments, quoted as a single argument list.
Do not send a user message and do not type a Codex slash command.

The script prints a leading-space /force-model line. The Weave Router reads that
exec output, pins the session, and continues this turn — so run the script once and
do not repeat its output as your answer. Then report the router's response.
