@@ -59,6 +59,7 @@ Docs: https://docs.openclaw.ai
 - Telegram/Polling: clear Telegram webhooks (`deleteWebhook`) before starting long-poll `getUpdates`, including retry handling for transient cleanup failures.
 - Telegram/Webhook: add `channels.telegram.webhookPort` config support and pass it through plugin startup wiring to the monitor listener.
 - Telegram/Media: send a user-facing Telegram reply when media download fails (non-size errors) instead of silently dropping the message.
+- Agents/Media: route tool-result `MEDIA:` extraction through shared parser validation so malformed prose like `MEDIA:-prefixed ...` is no longer treated as a local file path (prevents Telegram ENOENT tool-error overrides). (#18780) Thanks @HOYALIM.
 - Logging: cap single log-file size with `logging.maxFileBytes` (default 500 MB) and suppress additional writes after cap hit to prevent disk exhaustion from repeated error storms.
 - Memory/Remote HTTP: centralize remote memory HTTP calls behind a shared guarded helper (`withRemoteHttpResponse`) so embeddings and batch flows use one request/release path.
 - Memory/Embeddings: apply configured remote-base host pinning (`allowedHostnames`) across OpenAI/Voyage/Gemini embedding requests to keep private/self-hosted endpoints working without cross-host drift. (#18198) Thanks @ianpcook.
