## Summary - add a shared-read serialization mode for global app-server request families - let consecutive leading shared reads for the same family run together while keeping exclusive requests ordered - mark only `skills/list`, `config/read` and `plugin/list` as shared reads for now ## Why `skills/list` and `plugin/list` are read-only config-family requests, but the app-server queue currently treats every config request as exclusive. That means one long `skills/list` can make a later `plugin/list` wait even though the two requests do not mutate config. This change keeps the existing queue order but lets adjacent reads overlap. If a write is already waiting, later reads still stay behind it, so writes do not starve. ## Scope This intentionally keeps the first pass narrow: - shared reads: `skills/list`, `plugin/list` - still exclusive: `plugin/install`, `marketplace/*`, `skills/config/write`, `config/*write`, `config/read`, and the rest of the config family ## Validation - `just fmt` - `cargo test -p codex-app-server-protocol` - `cargo test -p codex-app-server` - `just fix -p codex-app-server-protocol` - `just fix -p codex-app-server` ## Desktop verification I ran the dev desktop app against this branch's built binary with the existing UI timing logs enabled. The app did use `/Users/xli/code/codex_6/codex-rs/target/debug/codex`. The new scheduler behavior works, but this narrow change does not remove every cold-start delay: in the observed trace, an earlier exclusive `config/read` was already queued ahead of the later `skills/list` and `plugin/list` requests, so the page-open plugin requests still waited behind that earlier exclusive config-family request before they could run together. That means this PR is the scheduler primitive needed for shared reads, not the complete end-to-end latency fix by itself. ## Not run - full workspace test suite, because repo policy requires explicit approval before running it after touching `app-server-protocol`
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.
