+# TOOLS.md - User Tool Notes (editable)
+
+This file is for *your* notes about external tools and conventions.
+It does not define which tools exist; Clawdbot provides built-in tools internally.
+
+## Examples
+
+### imsg
+- Send an iMessage/SMS: describe who/what, confirm before sending.
+- Prefer short messages; avoid sending secrets.
+
+### sag
+- Text-to-speech: specify voice, target speaker/room, and whether to stream.
+
+Add whatever else you want the assistant to know about your local toolchain.
