## Why `codex-rs/core/src/tools/handlers/plan.rs` still owned both the `update_plan` runtime handler and the static tool definition. The tool definition is pure metadata, so keeping it in `codex-core` works against the ongoing effort to move tool-spec code into `codex-tools` and keep `codex-core` focused on orchestration and execution paths. This continues the extraction work from #16379, #16471, and #16477. ## What Changed - added `codex-rs/tools/src/plan_tool.rs` with `create_update_plan_tool()` - re-exported that constructor from `codex-rs/tools/src/lib.rs` - updated `codex-rs/core/src/tools/spec.rs` and `codex-rs/core/src/tools/spec_tests.rs` to use the `codex-tools` export instead of a core-local static - removed the old `PLAN_TOOL` definition from `codex-rs/core/src/tools/handlers/plan.rs`; the `PlanHandler` runtime logic still stays in `codex-core` - tightened two `codex-core` aliases to `#[cfg(test)]` now that production code no longer needs them ## Testing - `cargo test -p codex-tools` - `cargo test -p codex-core tools::spec::tests` --- [//]: # (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.
