ran evals against this, looks like on Codex it is failing to retrieve the right guide

on Claude Code and Jetski CLI the results looks like this:

maybe the task could use some tweaking?

Thanks @micahjo7. I seem to be blocked from installing Codex (haven't had to run it before) so I'm unable to eval it locally. Is there a change you think would help it pick up the guide?

I discovered this was a local eval issue- basically, Codex CLI in our eval harness does not inheriting PATH, meaning the npx search/retrieve calls were using the published version of the package rather than the local version. So when these evals ran, it did not have the guide in this CL within the CLI tool. After fixing that, the evals look good (consistent with the claude/jetski results above). Sorry for the false alarm!

Will work on a fix for the issue.

Ah ok great, thanks for confirming!

This LGTM though it's not an API I have deep expertise on. Might want to link to the Safari bug so the agent can verify it's still current (yes, we'd update the guide, but 💩 happens) and to avoid wasting tokens hunting it down itself.
