## Why First-party async traits should expose their `Send` contracts explicitly without requiring `async_trait`. This completes the migration pattern established in #27303 and #27304. ## What changed - Replaced the remaining first-party `async_trait` traits with native return-position `impl Future + Send` where statically dispatched and explicit boxed `Send` futures where object safety is required. - Kept implementations behavior-preserving, outlining existing async bodies into inherent methods where that keeps the diff reviewable. - Removed all direct first-party `async-trait` dependencies and the workspace dependency declaration. - Added a cargo-deny policy that permits `async-trait` only through the remaining transitive wrapper crates. - Updated `rand` from 0.8.5 to 0.8.6 to resolve RUSTSEC-2026-0097 and keep the full cargo-deny check passing. ## Validation - `just test -p codex-exec-server`: 216 passed, 2 skipped. - `just test -p codex-model-provider`: 39 passed. - `just test -p codex-core` and `just test`: changed tests passed; remaining failures are environment-sensitive suites unrelated to this migration. - `cargo deny check` - `just fix` - `just fmt` - `cargo shear` - `just bazel-lock-check`
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
