Agent IDE — Codex fork for AI-native development environment

zsh fork PR stack: - https://github.com/openai/codex/pull/12051 - https://github.com/openai/codex/pull/12052 👈 ### Summary This PR introduces a feature-gated native shell runtime path that routes shell execution through a patched zsh exec bridge, removing MCP-specific behavior from the shell hot path while preserving existing CommandExecution lifecycle semantics. When shell_zsh_fork is enabled, shell commands run via patched zsh with per-`execve` interception through EXEC_WRAPPER. Core receives wrapper IPC requests over a Unix socket, applies existing approval policy, and returns allow/deny before the subcommand executes. ### What’s included **1) New zsh exec bridge runtime in core** - Wrapper-mode entrypoint (maybe_run_zsh_exec_wrapper_mode) for EXEC_WRAPPER invocations. - Per-execution Unix-socket IPC handling for wrapper requests/responses. - Approval callback integration using existing core approval orchestration. - Streaming stdout/stderr deltas to existing command output event pipeline. - Error handling for malformed IPC, denial/abort, and execution failures. **2) Session lifecycle integration** SessionServices now owns a `ZshExecBridge`. Session startup initializes bridge state; shutdown tears it down cleanly. **3) Shell runtime routing (feature-gated)** When `shell_zsh_fork` is enabled: - Build execution env/spec as usual. - Add wrapper socket env wiring. - Execute via `zsh_exec_bridge.execute_shell_request(...)` instead of the regular shell path. - Non-zsh-fork behavior remains unchanged. **4) Config + feature wiring** - Added `Feature::ShellZshFork` (under development). - Added config support for `zsh_path` (optional absolute path to patched zsh): - `Config`, `ConfigToml`, `ConfigProfile`, overrides, and schema. - Session startup validates that `zsh_path` exists/usable when zsh-fork is enabled. - Added startup test for missing `zsh_path` failure mode. **5) Seatbelt/sandbox updates for wrapper IPC** - Extended seatbelt policy generation to optionally allow outbound connection to explicitly permitted Unix sockets. - Wired sandboxing path to pass wrapper socket path through to seatbelt policy generation. - Added/updated seatbelt tests for explicit socket allow rule and argument emission. **6) Runtime entrypoint hooks** - This allows the same binary to act as the zsh wrapper subprocess when invoked via `EXEC_WRAPPER`. **7) Tool selection behavior** - ToolsConfig now prefers ShellCommand type when shell_zsh_fork is enabled. - Added test coverage for precedence with unified-exec enabled. |

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.
