Codex
Enable Codex and configure it for Agent Session Manager panes.
What it is
Codex is one of the agent tools that can run inside an Agent Session Manager pane.
Why you might use it
Run Codex in an isolated Git worktree while organizing several agent tasks in tabs and panes.
Before you start
Install Codex and make sure its command is available from the shell selected in Settings → Panes → Terminal. Enable it in Settings → Harnesses.
How to use it
- Open New Pane in a tab.
- Choose Codex in Harness.
- Enter a session, branch, or worktree name.
- Review the Codex CLI Options shown in the sheet.
- Choose Create Pane.
Codex starts in the Git worktree prepared for the pane. The status line can show app-owned facts and supported Codex session information.
What you should see
The pane opens a Codex terminal and remains part of the tab’s saved layout.
After a restart, Codex panes reopen in their saved working copies. Continue on Restart does not add a separate continuation option to Codex.
If it does not work
- If Codex is missing from Harness, confirm that it is installed and available from the selected shell.
- If the pane exits immediately, review Settings → Panes → Terminal → Shell and the Codex options shown in Settings → Harnesses.
- If the Git worktree cannot be prepared, see Project Isolation.
