What issue are you seeing?

I am seeing a remote compact task failure in Codex CLI that ends with a rate-limit response after retries are exhausted.
■ Error running remote compact task: exceeded retry limit, last status: 429 Too Many Requests, request id: req_88e475f349d344c2a936778c88b0b02e
This appears to be happening during the remote compact/feedback flow rather than from a normal local shell command failure.

What steps can reproduce the bug?

1. Start a Codex CLI session and work through a normal coding/debugging flow.
2. Continue long enough for Codex to trigger a remote compact task.
3. Observe the task fail after retries with:

• 429 Too Many Requests
• exceeded retry limit

1. Codex then reports the uploaded feedback/thread ID and asks to open a GitHub issue.

What is the expected behavior?

The remote compact task should either:
• complete successfully, or
• fail gracefully with a clearer actionable message and recovery path.

It should ideally not hit repeated retries and then abort with a final 429 if the client can back off or defer the compact task more cleanly.
