## Summary Make blocking hook behavior reliable for tools invoked from code mode. Previously, a `PostToolUse` hook could block a completed tool result, but code mode would still return the original typed result to JavaScript. The hook appeared blocked in hook telemetry while the running script continued with the result. This change: - rejects the nested JavaScript tool promise when `PostToolUse` blocks - normalizes `decision: "block"` and exit code 2 to the same blocking behavior - surfaces the hook feedback as the rejected promise's error - adds end-to-end coverage for the relevant PreToolUse and PostToolUse interactions ## Hook semantics in code mode | Hook behavior | Code-mode result | |---|---| | PreToolUse block | Reject the promise before the tool executes | | PreToolUse `updatedInput` | Execute the rewritten invocation and return its result | | PostToolUse `decision: "block"` | Execute the tool, then reject the promise with the hook reason | | PostToolUse exit code 2 | Same behavior as `decision: "block"` | | PostToolUse `continue: false` | Preserve the existing feedback-only behavior; do not reject the promise | ## Test coverage Added or strengthened end-to-end coverage proving that: - a PreToolUse block rejects the JavaScript promise before execution - a PreToolUse input rewrite executes only the rewritten command - JavaScript receives the rewritten command's result - PostToolUse `decision: "block"` rejects after the command executes - PostToolUse exit code 2 has the same behavior - the hook observes the original completed tool response - the blocked original result does not reach JavaScript - existing direct-mode replacement behavior remains intact - `continue: false` without a reason produces deterministic fallback feedback

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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
