Agent IDE — Codex fork for AI-native development environment
18acec09df
# Summary - Fix resume/fork config rebuild so cwd changes inside the TUI produce a fully rebuilt Config (trust/approval/sandbox) instead of mutating only the cwd. - Preserve `--add-dir` behavior across resume/fork by normalizing relative roots to absolute paths once (based on the original cwd). - Prefer latest `TurnContext.cwd` for resume/fork prompts but fall back to `SessionMeta.cwd` if the latest cwd no longer exists. - Align resume/fork selection handling and ensure UI config matches the resumed thread config. - Fix Windows test TOML path escaping in trust-level test. # Details - Rebuild Config via `ConfigBuilder` when resuming into a different cwd; carry forward runtime approval/sandbox overrides. - Add `normalize_harness_overrides_for_cwd` to resolve relative `additional_writable_roots` against the initial cwd before reuse. - Guard `read_session_cwd` with filesystem existence check for the latest `TurnContext.cwd`. - Update naming/flow around cwd comparison and prompt selection. <img width="603" height="150" alt="Screenshot 2026-01-23 at 5 42 13 PM" src="https://github.com/user-attachments/assets/d1897386-bb28-4e8a-98cf-187fdebbecb0" /> And proof the model understands the new cwd: <img width="828" height="353" alt="Screenshot 2026-01-22 at 5 36 45 PM" src="https://github.com/user-attachments/assets/12aed8ca-dec3-4b64-8dae-c6b8cff78387" /> |

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 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.
Using Codex with your ChatGPT plan
Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Team, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
You can also use Codex with an API key, but this requires additional setup.
