What version of Codex is running?

openai.chatgpt 0.4.46

What subscription do you have?

Pro

Which model were you using?

GPT-5.1-Codex-Max

What platform is your computer?

Darwin 24.6.0 arm64 arm

What issue are you seeing?

It happened multiple times already. At some point (more than 20% context size) the model responds that it has no access for tools, ability to read files (even with direct '@' context mark). I've seen in other conversation that in the CoT it start to test simple cli commands like ls, ripgrep, cat etc. without luck.

Sometime when explicit instructed to use avaible tools it regain the access for shor time. In general i'm forced to start new conversation.

Thanks for the bug report. We'll share the feedback with the team responsible for training our codex models. If you see other model behavior that you'd like to report, please use the /feedback command. That will provide us with additional details including logs and conversation text.
