${HOME}/.agents/skills/react-message/scripts/react-message.ts \
--session-id "$SESSION_ID" \
--emoji "👍"
--session-id: Use the session id rendered in your system prompt. $SESSION_ID works only in per-spawn deployments; in shared-process mode it is not set and the skill library resolves the owning session automatically — a mismatched value is never honored.
