Sandbox environment access failure for Codex reviews
Technical Positioning
Secure and functional code review environment.
SaaS Insight & Market Implications
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.

Review fails due to unknown sandboxing variant
After a fresh installation and being logged into Codex inside of Claude Code, when asking for a /codex:review, the companion script seems to transmit the wrong variant for the sandbox value that should be spawned. Hence the review command errors. codex-cli 0.117.0
Developer Debate & Comments
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. ```
Thanks for flagging. I'm looking into this!
@arvidkahl inside bash can you run `which codex` and `codex --version`? There might be a version mismatch happening here.
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.
Thank you! That's definitely odd since we moved from `readOnly` to `read-only` back in December. Will do some more digging with Codex

How would this be different than using `/codex:rescue`? It should by default suggest to use the same thread or you can use `/codex:rescue --resume [follow-up]` to be more explicit
Great point -- from my own implementation as a skill they do overlap mechanically since both use threads under the hood. The difference is really about what I am trying to do with it. With `rescue`...
