 - `/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).
