AI Executive Synthesis
Secure and functional code review environment.
This issue reveals a critical failure in the Codex plugin's sandbox environment, preventing code reviews from executing. The error, stemming from an "unknown sandboxing variant" and inability to access the shell, points to a fundamental configuration or compatibility problem within the execution environment. The mention of a `readOnly` to `read-only` change suggests a breaking change in sandbox parameterization that the plugin or CLI might not be correctly handling. This directly impacts the core utility of the `/codex:review` command, rendering it unusable for affected users. Such sandbox failures are severe, compromising both functionality and security, demanding immediate resolution for plugin reliability.

Thank you! That's definitely odd since we moved from `readOnly` to `read-only` back in December. Will do some more digging with Codex
The binary from `which codex` also returns `codex-cli 0.117.0` (if it helps, it's located at `/Users/arvidkahl/Library/Application Support/Herd/config/nvm/versions/node/v21.7.3/bin/codex` as I run this through Herd and inside PHPStorm.
@arvidkahl inside bash can you run `which codex` and `codex --version`? There might be a version mismatch happening here.
Thanks for flagging. I'm looking into this!
I get similar issue with sandbox environment.
```
The Codex reviewer couldn't access the shell in its sandbox. The review output is above — it was unable to execute due to sandbox restrictions in this environment.
