Agent IDE — Codex fork for AI-native development environment
226241f035
## Summary - move `guardian_developer_instructions` from managed config into workspace-managed `requirements.toml` - have guardian continue using the override when present and otherwise fall back to the bundled local guardian prompt - keep the generalized prompt-quality improvements in the shared guardian default prompt - update requirements parsing, layering, schema, and tests for the new source of truth ## Context This replaces the earlier managed-config / MDM rollout plan. The intended rollout path is workspace-managed requirements, including cloud enterprise policies, rather than backend model metadata, Statsig, or Jamf-managed config. That keeps the default/fallback behavior local to `codex-rs` while allowing faster policy updates through the enterprise requirements plane. This is intentionally an admin-managed policy input, not a user preference: the guardian prompt should come either from the bundled `codex-rs` default or from enterprise-managed `requirements.toml`, and normal user/project/session config should not override it. ## Updating The OpenAI Prompt After this lands, the OpenAI-specific guardian prompt should be updated through the workspace Policies UI at `/codex/settings/policies` rather than through Jamf or codex-backend model metadata. Operationally: - open the workspace Policies editor as a Codex admin - edit the default `requirements.toml` policy, or a higher-precedence group-scoped override if we ever want different behavior for a subset of users - set `guardian_developer_instructions = """..."""` to the full OpenAI-specific guardian prompt text - save the policy; codex-backend stores the raw TOML and `codex-rs` fetches the effective requirements file from `/wham/config/requirements` When updating the OpenAI-specific prompt, keep it aligned with the shared default guardian policy in `codex-rs` except for intentional OpenAI-only additions. ## Testing - `cargo check --tests -p codex-core -p codex-config -p codex-cloud-requirements --message-format short` - `cargo run -p codex-core --bin codex-write-config-schema` - `cargo fmt` - `git diff --check` Co-authored-by: Codex <noreply@openai.com> |

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.
Using Codex with your ChatGPT plan
