Summary

In Codex CLI v0.93.0, /plan requires collaboration_mode (per the GitHub issues linked from the changelog). However, /experimental does not list collaboration_mode among toggleable features, so there’s no discoverable way to enable the gate from within the CLI.

Expected

Because /plan requires collaboration_mode and the feature is user-toggleable, /experimental should list collaboration_mode so users can enable it.

Actual

/experimental lists other toggleable experimental features, but not collaboration_mode.

Example output:

Can you say more about the problem you're seeing? Are you trying to use /plan and seeing a problem with it? If so, please provide repro steps.

I read about the new /plan feature in the changelog and wanted to try it out.
I noted that the changelog indicated it was "feature gated" so I used /experimental in the codex-cli but didn't see an appropriate looking feature to enable.

I came back to the changelog and opened the first ticket linked to the /plan item. It didn't contain any information about the needed feature.
I opened the second ticket and found mention there that the feature that was needed was collaboration_mode.
I then had to edit my config.toml file and add that feature by hand.

My expectation was that it would be listed in /experimental to make it easy for someone to try out the new /plan feature that was mentioned in the changelog.

Plan mode is still under development. We'll announce when it's ready for experimental use.
