Agent IDE — Codex fork for AI-native development environment
80d7a5d7fe
### Description - Remove the now-unused `instructions` field from the session metadata to simplify SessionMeta and stop propagating transient instruction text through the rollout recorder API. This was only saving user_instructions, and was never being read. - Stop passing user instructions into the rollout writer at session creation so the rollout header only contains canonical session metadata. ### Testing - Ran `just fmt` which completed successfully. - Ran `just fix -p codex-protocol`, `just fix -p codex-core`, `just fix -p codex-app-server`, `just fix -p codex-tui`, and `just fix -p codex-tui2` which completed (Clippy fixes applied) as part of verification. - Ran `cargo test -p codex-protocol` which passed (28 tests). - Ran `cargo test -p codex-core` which showed failures in a small set of tests (not caused by the protocol type change directly): `default_client::tests::test_create_client_sets_default_headers`, several `models_manager::manager::tests::refresh_available_models_*`, and `shell_snapshot::tests::linux_sh_snapshot_includes_sections` (these tests failed in this CI run). - Ran `cargo test -p codex-app-server` which reported several failing integration tests (including `suite::codex_message_processor_flow::test_codex_jsonrpc_conversation_flow`, `suite::output_schema::send_user_turn_*`, and `suite::user_agent::get_user_agent_returns_current_codex_user_agent`). - `cargo test -p codex-tui` and `cargo test -p codex-tui2` were attempted but aborted due to disk space exhaustion (`No space left on device`). ------ [Codex Task](https://chatgpt.com/codex/tasks/task_i_696bd8ce632483228d298cf07c7eb41c) |

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.
