Agent IDE — Codex fork for AI-native development environment

Direct skill-script matches force `Decision::Prompt`, so skill-backed scripts require explicit approval before they run. (Note "allow for session" is not supported in this PR, but will be done in a follow-up.) In the process of implementing this, I fixed an important bug: `ShellZshFork` is supposed to keep ordinary allowed execs on the client-side `Run` path so later `execve()` calls are still intercepted and reviewed. After the shell-escalation port, `Decision::Allow` still mapped to `Escalate`, which moved `zsh` to server-side execution too early. That broke the intended flow for skill-backed scripts and made the approval prompt depend on the wrong execution path. ## What changed - In `codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs`, `Decision::Allow` now returns `Run` unless escalation is actually required. - Removed the zsh-specific `argv[0]` fallback. With the `Allow -> Run` fix in place, zsh's later `execve()` of the script is intercepted normally, so the skill match happens on the script path itself. - Kept the skill-path handling in `determine_action()` focused on the direct `program` match path. ## Verification - Updated `shell_zsh_fork_prompts_for_skill_script_execution` in `codex-rs/core/tests/suite/skill_approval.rs` (gated behind `cfg(unix)`) to: - run under `SandboxPolicy::new_workspace_write_policy()` instead of `DangerFullAccess` - assert the approval command contains only the script path - assert the approved run returns both stdout and stderr markers in the shell output - Ran `cargo test -p codex-core shell_zsh_fork_prompts_for_skill_script_execution -- --nocapture` ## Manual Testing Run the dev build: ``` just codex --config zsh_path=/Users/mbolin/code/codex2/codex-rs/app-server/tests/suite/zsh --enable shell_zsh_fork ``` I have created `/Users/mbolin/.agents/skills/mbolin-test-skill` with: ``` ├── scripts │ └── hello-mbolin.sh └── SKILL.md ``` The skill: ``` --- name: mbolin-test-skill description: Used to exercise various features of skills. --- When this skill is invoked, run the `hello-mbolin.sh` script and report the output. ``` The script: ``` set -e # Note this script will fail if run with network disabled. curl --location openai.com ``` Use `$mbolin-test-skill` to invoke the skill manually and verify that I get prompted to run `hello-mbolin.sh`. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.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.
