## Why `openai/openai#947613` adds `X-Codex-Rate-Limit-Reached-Type` for Codex workspace credit-depletion and spend-cap responses. The CLI currently reads the adjacent promo header but otherwise renders generic usage-limit copy, so those responses do not explain the workspace-specific action the user needs to take. Backend dependency: https://github.com/openai/openai/pull/947613 ## What Changed - Parse `X-Codex-Rate-Limit-Reached-Type` in the usage-limit error handling path alongside `x-codex-promo-message`. - Keep the header value parsing with the shared `RateLimitReachedType` enum. - Carry the parsed type on `UsageLimitReachedError` and render client-owned copy for the four workspace owner/member credit and spend-cap values. - Preserve existing promo and plan-based text for absent, generic, or unknown header values. - Keep the existing TUI workspace-owner nudge state path unchanged; the response header only selects the displayed error string. - Add focused display coverage for all specific type values and the generic fallback case. ## Test Plan - Added `usage_limit_reached_error_formats_rate_limit_reached_types` coverage. - Not run manually, per request; CI runs validation on the pushed commit.
Codex CLI is a coding agent from OpenAI that runs locally on your computer.

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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
