What's Wrong?

During sustained tool-call activity (long tasks: multi-file edits + git push + smoke tests + server restart), the telegram MCP plugin (plugin:telegram:telegram from claude-plugins-official 0.0.6) disconnects mid-task. The reply / react / edit_message / download_attachment tools become unavailable. Plugin auto-reconnects after the burst of activity ends. This recurs 3-5 times within a 30-min heavy task and breaks mid-task replies.

What Should Happen?

The telegram MCP plugin should remain connected throughout long-running tasks. Reply / react / edit_message tools should not drop mid-task.
