## Why This continues the `codex-tools` migration by moving another passive tool-definition layer out of `codex-core`. After `ResponsesApiTool` and the lower-level schema adapters moved into `codex-tools`, `core/src/client_common.rs` was still owning `ToolSpec` and the web-search request wire types even though they are serialized data models rather than runtime orchestration. Keeping those types in `codex-core` makes the crate boundary look smaller than it really is and leaves non-runtime tool-shape code coupled to core. ## What changed - moved `ToolSpec`, `ResponsesApiWebSearchFilters`, and `ResponsesApiWebSearchUserLocation` into `codex-rs/tools/src/tool_spec.rs` - added focused unit tests in `codex-rs/tools/src/tool_spec_tests.rs` for: - `ToolSpec::name()` - web-search config conversions - `ToolSpec` serialization for `web_search` and `tool_search` - kept `codex-rs/tools/src/lib.rs` exports-only by re-exporting the new module from `lib.rs` - reduced `core/src/client_common.rs` to a compatibility shim that re-exports the extracted tool-spec types for current core call sites - updated `core/src/tools/spec_tests.rs` to consume the extracted web-search types directly from `codex-tools` - updated `codex-rs/tools/README.md` so the crate contract reflects that `codex-tools` now owns the passive tool-spec request models in addition to the lower-level Responses API structs ## Test plan - `cargo test -p codex-tools` - `cargo test -p codex-core --lib tools::spec::` - `cargo test -p codex-core --lib client_common::` - `just fix -p codex-tools -p codex-core` - `just argument-comment-lint` ## References - #15923 - #15928 - #15944 - #15953 - #16031
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.
