 ### Fixes
 
+- Telegram/Agents: gate exec/bash tool-failure warnings behind verbose mode so default Telegram replies stay clean while verbose sessions still surface diagnostics. (#20560) Thanks @obviyus.
 - Gateway/Daemon: forward `TMPDIR` into installed service environments so macOS LaunchAgent gateway runs can open SQLite temp/journal files reliably instead of failing with `SQLITE_CANTOPEN`. (#20512) Thanks @Clawborn.
 - Agents/Billing: include the active model that produced a billing error in user-facing billing messages (for example, `OpenAI (gpt-5.3)`) across payload, failover, and lifecycle error paths, so users can identify exactly which key needs credits. (#20510) Thanks @echoVic.
 - iOS/Screen: move `WKWebView` lifecycle ownership into `ScreenWebView` coordinator and explicit attach/detach flow to reduce gesture/lifecycle crash risk (`__NSArrayM insertObject:atIndex:` paths) during screen tab updates. (#20366) Thanks @ngutman.
