Agent IDE — Codex fork for AI-native development environment
c7c2b3cf8d
### Motivation - The local OAuth callback server returned a generic "Invalid OAuth callback" on failures even when the query contained an `error_description`, making it hard to debug OAuth failures. ### Description - Update `codex-rs/rmcp-client/src/perform_oauth_login.rs` to surface `error_description` values from the callback query in the HTTP response. - Introduce a `CallbackOutcome` enum and change `parse_oauth_callback` to return it, parsing `code`, `state`, and `error_description` from the query string. - Change `spawn_callback_server` to match on `CallbackOutcome` and return `OAuth error: <description>` with a 400 status when `error_description` is present, while preserving the existing success and invalid flows. - Use inline formatting for the error response string. ### Testing - Ran `just fmt` in the `codex-rs` workspace to format changes successfully. - Ran `cargo test -p codex-rmcp-client` and all tests passed. ------ [Codex Task](https://chatgpt.com/codex/tasks/task_i_6971aadc68d0832e93159efea8cd48a9) |

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.
