 ### Fixes
 
 - Plugins/inspector: keep bundled plugin runtime capture quiet and config-tolerant for Codex, memory-lancedb, Feishu, Mattermost, QQBot, and Tlon so plugin-inspector JSON checks can validate the full bundled set. Thanks @vincentkoc.
+- Slack/auto-reply: keep fully consumed text reset triggers such as `new session` out of `BodyForAgent` after directive cleanup, so configured Slack reset phrases do not leak into the fresh model turn. Fixes #73137. Thanks @neeravmakwana.
 - Gateway/startup: start chat channels without waiting for primary model prewarm, keeping model warmup bounded in the background so Slack and other channels come online promptly when provider discovery is slow. Supersedes #73420. Thanks @dorukardahan.
 - Gateway/install: carry env-backed config SecretRefs such as `channels.discord.token` into generated service environments when they are present only in the installing shell, while keeping gateway auth SecretRefs non-persisted. Fixes #67817; supersedes #73426. Thanks @wdimaculangan and @ztexydt-cqh.
 - Auto-reply/commands: stop bare `/reset` and `/new` after reset hooks acknowledge the command, so non-ACP channels no longer fall through into empty provider calls while `/reset <message>` and `/new <message>` still seed the next model turn. Fixes #73367 and #73412. Thanks @hoyanhan, @wenxu007, and @amdhelper.
