Codex Sync
VS Code extensions cannot reliably write directly into another app's input box through an official Codex API. This extension therefore provides two practical paths:
macos-osascript (default): copies the reference, activates the Codex macOS app, waits only until it becomes frontmost, and pastes into the focused field. macOS may ask VS Code for Accessibility/Automation permission.custom-command: runs a shell command that you control. The command can use placeholders such as ${reference}, ${file}, ${lineStart}, and ${kind}.
If sync is not available, the reference is still copied to the clipboard.
