What issue are you seeing?

On July 14th, 2026 at around 23:00 Tallinn time (UTC+2), I started a Codex CLI session using the gpt‑5.6‑sol Ultra Fast model to make a small change related to fencing / ownership tokens and lease_token handling. After issuing the change, I stopped interacting with Codex and expected the process to finish.

However, Codex entered a repeated “waiting for agents” loop and continued running in the background without any new input from me. The pattern looked like:

• Waiting for agents

• Finished waiting
└ No agents completed yet
repeated many times, plus • Interacted with /root/impl_jobs_failure_snapshot.

Eventually, I received:
■ You've hit your usage limit. Visit https://chatgpt.com/codex/settings/usage to purchase more credits or try again at Jul 21st, 2026 11:57 PM.

As a result, my entire weekly Codex limit was consumed by this background loop, even though I was not actively using Codex and did not issue additional commands. This feels like an infinite “waiting for agents / no agents completed yet” loop silently burning credits in the background.

What steps can reproduce the bug?

What is the expected behavior?

Codex should stop or time‑out the agent workflow instead of running an infinite “waiting for agents / no agents completed yet” loop in the background.

In this situation I expected:

the small configuration change to complete with minimal usage;

no further credits to be consumed once there is no user interaction;

either a clear error about agents not completing or an automatic stop, rather than silently burning the entire weekly limit.

Additional information

Codex CLI status after the incident (v0.144.4) shows:

Model: gpt‑5.6‑sol (reasoning ultra, summaries auto)

Session: 019f62cd-fc3b-7731-8713-c6c5e89733da

Weekly limit: 0% left (resets 23:57 on 21 Jul)

I can provide the full CLI session log and a screenshot of the usage/settings page if needed. This looks like an internal background loop consuming credits without user interaction on gpt‑5.6‑sol Ultra Fast.
