Addresses #22833, #22245, #23067 ## Why `/goal` can keep synthesizing turns even when the next turn cannot make meaningful progress. Hard usage exhaustion can replay failing turns, and repeated permission or external-resource blockers can keep burning tokens while waiting for user or system intervention. ## What changed - Add resumable `blocked` and `usageLimited` goal states. As with `paused`, goal continuation stops with these states. - Move to `usageLimited` after usage-limit failures. - Allow the built-in `update_goal` tool to set `blocked` only under explicit repeated-impasse guidance. Updated goal continuation prompt to specify that agent should use `blocked` only when it has made at least three attempts to get past an impasse. Most of the files touched by this PR are because of the small app server protocol update. ## Validation I manually reproduced a number of situations where an agent can run into a true impasse and verified that it properly enters `blocked` state. I then resumed and verified that it once again entered `blocked` state several turns later if the impasse still exists. I also manually reproduced the usage-limit condition by creating a simulated responses API endpoint that returns 429 errors with the appropriate error message. Verified that the goal runtime properly moves the goal into `usageLimited` state and TUI UI updates appropriately. Verified that `/goal resume` resumes (and immediately goes back into `ussageLImited` state if appropriate). ## Follow-up PRs Small changes will be needed to the GUI clients to properly handle the two new states.
npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
