Error message

${result.reason}

What it means

Inside the `codex model` command, the in-page automation script returns `{ ok: false, reason, detail }` for any DOM-level failure (composer missing, trigger button not found, menu not opening, no/ambiguous match). The Node side rethrows that reason as a CommandExecutionError at this line, so this error carries whatever the browser script reported. It is the umbrella failure point for the click-and-select automation inside the Codex UI.

Solutions

1. Open a chat in Codex so the composer and model button are visible, then retry.
2. Run `opencli codex model --list` to test whether the menu can be opened at all; if it fails, the DOM drifted — update opencli.
3. Retry once; slow renders sometimes exceed the menu-open wait window.
4. Read the error's reason/detail (e.g. 'Model menu did not open after click.') to target the specific failing step.

Example fix

// before
opencli codex model "gpt-5.5"   // fails: 'model trigger button not found in composer'
// after
# open a chat first so the composer exists
opencli codex model --list       # verify menu opens / DOM matches
opencli codex model "gpt-5.5"

// ensure a chat/composer exists before switching
const current = await run('opencli codex model'); // throws selectorError if no composer
if (!current) await openNewChat();

function automationResultOk(r) { return r && typeof r === 'object' && r.ok === true; }

try {
  await switchModel(name);
} catch (err) {
  if (err instanceof CommandExecutionError) {
    // reason in err.message/detail; wait for UI and retry once
    await sleep(2000);
    return switchModel(name);
  }
  throw err;
}

When it happens

Trigger: Running `opencli codex model <name>` when the evaluate script sets ok:false: composer contenteditable not found, model trigger button not matched by MODEL_BTN_TEXT_RE, menu items didn't appear within ~1.3s of the synthetic click, or zero/ambiguous normalized label matches inside the page script.

Common situations: No chat open in Codex so no composer exists; a Codex update changed the composer toolbar DOM so the regex no longer matches; slow UI where the menu takes longer than the 16×80ms wait; synthetic clicks ignored by an updated menu component.
