"My DingTalk Coding Bot Said It Started the Task. Then It Never Sent the Result"

The most annoying mobile-agent failure is not a crash.

It is the fake success message.

You send a task from DingTalk. The bot replies:

Task accepted.

Then Claude Code or Codex actually runs for a while, finishes the work, and nothing comes back to the phone.

That is worse than an immediate error. It makes you think the agent is still working, when the real problem is that the result fell out of the delivery path.

The setup

I have been building

I am curious how other people are handling mobile agent delivery. Do you send one "task accepted" message, or do you wire final runtime events back into the original chat thread?
