 ## Agent-Specific Notes
 - Vocabulary: "makeup" = "mac app".
+- When answering questions, respond with high-confidence answers only: verify in code; do not guess.
 - Gateway currently runs only as the menubar app; there is no separate LaunchAgent/helper label installed. Restart via the Clawdbot Mac app or `scripts/restart-mac.sh`; to verify/kill use `launchctl print gui/$UID | grep clawdbot` rather than assuming a fixed label. **When debugging on macOS, start/stop the gateway via the app, not ad-hoc tmux sessions; kill any temporary tunnels before handoff.**
 - macOS logs: use `./scripts/clawlog.sh` (aka `vtlog`) to query unified logs for the Clawdbot subsystem; it supports follow/tail/category filters and expects passwordless sudo for `/usr/bin/log`.
 - If shared guardrails are available locally, review them; otherwise follow this repo's guidance.
