Add Codex default session mode

Codex does not currently expose a provider-specific default session mode variable in line with:

• agent-shell-anthropic-default-session-mode-id
• agent-shell-github-default-session-mode-id
• agent-shell-opencode-default-session-mode-id

Would you be open to adding a Codex equivalent and wiring it into agent-shell-openai-make-codex-config via :default-session-mode-id?

From my research, codex-acp has these session modes/presets:

• read-only
• auto
• full-access

agent-shell already has generic support for :default-session-mode-id and this would let packages and user configs select a default Codex session mode at startup without requiring a custom wrapper or post-start mode switching.

Thanks for filing.

Would you be open to adding a Codex equivalent and wiring it into agent-shell-openai-make-codex-config via :default-session-mode-id?

Certainly. They've all been added as people request them :)

There's also model equivalents like agent-shell-anthropic-default-model-id.

Would you be interested in sending a PR? It's basically doing the same as done in the providers you already found.

Will do! I started making a PR but then saw the part about starting with a feature request.

Thanks for the reply!

Thank you for that. It helps with alignment and saves everyone time.
