## Preamble (run first) No auto-run steps. Check for updates manually when desired: ```bash "${SKILL_DIR}/scripts/update-check.sh" ``` This script is opt-in only.

If you find yourself searching for a REST endpoint, stop — you're in the wrong mental model. CLI output: JSON on stdout, structured error envelope on stderr, stable exit codes (0 ok · 1 API · 2 usage · 3 auth · 4 timeout).
