## Why `parse_tool_input_schema` and the supporting `JsonSchema` model were living in `core/src/tools/spec.rs`, but they already serve callers outside `codex-core`. Keeping that shared schema parsing logic inside `codex-core` makes the crate boundary harder to reason about and works against the guidance in `AGENTS.md` to avoid growing `codex-core` when reusable code can live elsewhere. This change takes the first extraction step by moving the schema parsing primitive into its own crate while keeping the rest of the tool-spec assembly in `codex-core`. ## What changed - added a new `codex-tools` crate under `codex-rs/tools` - moved the shared tool input schema model and sanitizer/parser into `tools/src/json_schema.rs` - kept `tools/src/lib.rs` exports-only, with the module-level unit tests split into `json_schema_tests.rs` - updated `codex-core` to use `codex-tools::JsonSchema` and re-export `parse_tool_input_schema` - updated `codex-app-server` dynamic tool validation to depend on `codex-tools` directly instead of reaching through `codex-core` - wired the new crate into the Cargo workspace and Bazel build graph
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.
