Codex credits are draining while idle / not actively used

I may have found the source of the issue. I have turned off Settings → General → Suggested prompts- Suggest what to do next by searching project files and connected apps and I don’t see usage drain anymore.

It could be just coincidence but I believe this is the cause of the usage drain.

I checked ~/.codex directory and saw an ambient-suggestions directory with json files containing “suggestions” - And they look like prompt responses that I have not asked for. Then I used Gemini to track all codex logs while I changed to a project and prompted it and apparently Codex sent 88k tokens after prompt response while idle. It was sending git and file system info in prompts using gpt-5.4 model. I have 5.5 set. I can see it in the logs
