+## Runtime debug overrides
+
+Use `/debug` in chat to set **runtime-only** config overrides (memory, not disk).
+This is handy when you need to toggle obscure settings without editing `clawdbot.json`.
+
+Examples:
+
+```
+/debug show
+/debug set messages.responsePrefix="[clawdbot]"
+/debug unset messages.responsePrefix
+/debug reset
+```
+
+`/debug reset` clears all overrides and returns to the on-disk config.

 - `/verbose` is meant for debugging and extra visibility; keep it **off** in normal use.
 - `/reasoning` (and `/verbose`) are risky in group settings: they may reveal internal reasoning or tool output you did not intend to expose. Prefer leaving them off, especially in group chats.
 
+## Debug overrides
+
+`/debug` lets you set **runtime-only** config overrides (memory, not disk). Owner-only.
+
+Examples:
+
+```
+/debug show
+/debug set messages.responsePrefix="[clawdbot]"
+/debug set whatsapp.allowFrom=["+1555","+4477"]
+/debug unset messages.responsePrefix
+/debug reset
+```
+
+Notes:
+- Overrides apply immediately to new config reads, but do **not** write to `clawdbot.json`.
+- Use `/debug reset` to clear all overrides and return to the on-disk config.

 ## Surface notes
 
 - **Text commands** run in the normal chat session (DMs share `main`, groups have their own session).
