 ### Fixes
 
 - Agents/sessions: keep delayed `sessions_send` A2A replies alive after soft wait-window timeouts, while preserving terminal run timeouts and avoiding stale target replies in requester sessions. Fixes #76443. Thanks @ryswork1993 and @vincentkoc.
+- CLI/sessions: keep intentional empty agent replies silent after tool-delivered channel output, instead of surfacing a misleading "No reply from agent." fallback. Thanks @vincentkoc.
 - Config/doctor: cap `.clobbered.*` forensic snapshots per config path and serialize snapshot writes so repeated `doctor --fix` recovery loops cannot flood the config directory. Fixes #76454; carries forward #65649. Thanks @JUSTICEESSIELP, @rsnow, and @vincentkoc.
 - Feishu: suppress duplicate text when replies send native voice media while preserving captions for ordinary audio files and falling back to text plus attachment links when voice uploads fail.
 - Feishu: keep packaged Feishu startup from bundling the Lark SDK's ESM `__dirname` path by loading the SDK as a plugin-local runtime dependency. Fixes #76291 and #76494. (#76392) Thanks @zqchris.
