Codex Gives Your Terminal Agent Status Signals

Codex’s 0.163.0 prerelease adds Program Status Protocol signals so terminals can distinguish working, done, error, and the kinds of prompts that block an agent—without scraping screens or watching window titles. We explain how the signals latch until you interact, what to expect from terminal integrations, and cover recent changes to managed worktrees, image previews, model catalogs, and WebSocket request limits.
