 ### Fixes
 
+- Plugins/install: remove the previous managed plugin directory when a reinstall switches sources, so stale ClawHub and npm copies no longer keep duplicate plugin ids in discovery after the new install wins. Thanks @vincentkoc.
 - Plugins/install: let official plugin reinstall recovery repair source-only installed runtime shadows, so `openclaw plugins install npm:@openclaw/discord --force` can replace the bad package instead of stopping at stale config validation. Thanks @vincentkoc.
 - Plugins/commands: allow the official ClawHub Codex plugin package to keep reserved `/codex` command ownership, matching the existing npm-managed Codex package behavior. Thanks @vincentkoc.
 - Plugins/commands: scope QQBot framework slash commands to the QQBot channel so `/bot-*` command handlers and native specs do not leak onto unrelated chat surfaces. Thanks @vincentkoc.
