## Summary - Rewrite migrated external-agent hook commands by replacing the full hook script path token instead of only the `.claude/hooks/` segment. - Preserve quoting around the full rewritten target path so script names with spaces, absolute paths, and shell operators/redirection continue to work. - Apply `.claude/settings.local.json` over `.claude/settings.json` for config, MCP, and plugin migration so local scope matches Claude settings precedence. - Skip legacy command markdown without `description` frontmatter, including README-style docs under `.claude/commands`. ## Root Cause The previous hook rewrite handled `.claude/hooks/` as a substring replacement. For absolute source commands, that left the original project-root prefix before the newly quoted `.codex/hooks` directory, producing invalid commands like `project/'project/.codex/hooks'/script.sh`. The migration also only used project `settings.json` for config/MCP/plugin decisions, so local settings such as `disabledMcpjsonServers` could be ignored even though Claude gives local settings higher precedence than project settings. ## Validation - `just fmt` - `cargo test -p codex-external-agent-migration` - `cargo test -p codex-app-server external_agent_config` - `just fix -p codex-external-agent-migration` - `just fix -p codex-app-server` - `git diff --check`
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.
