## Why Extension-owned tools currently receive a stripped `ToolCall` with only `call_id`, `tool_name`, and `payload`. That makes extension work that needs turn-local execution context awkward, especially web-search extension work that needs the active `truncation_policy` at tool invocation time. Reconstructing that value from config or `ExtensionData` would be indirect and could drift from the actual turn context, so the cleaner fix is to pass the needed turn metadata directly on the extension-facing invocation type. ## What changed - added `turn_id` and `truncation_policy` to `codex_tools::ToolCall` - populated those fields when core adapts `ToolInvocation` into an extension tool call - added a focused adapter test that verifies extension executors receive the forwarded turn metadata - updated the memories extension tests to construct the richer `ToolCall` - added the `codex-utils-output-truncation` dependency to `codex-tools` and refreshed lockfiles ## Testing - `cargo test -p codex-tools` - `cargo test -p codex-memories-extension` - `cargo test -p codex-core passes_turn_fields_to_extension_call` - `just bazel-lock-update` - `just bazel-lock-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.
