Issues with Background Agents (claude sonnet 4.5)

Using Background Agents in Slack.

Sometimes the agent’s message in Slack does not reflect the conversation (when I click into “open in Web”)

For example, I’ll ask “@Cursor run code get_balance.py”. It will run the code (returning 0.00, at least in the code or chat). Thin in Slack, it will return “Balance: 1000”.

Am I using it wrong? Wrong model? What gives?
