## Why Hosted orchestrator skills are read through the remote MCP resource server. Within one thread, the same catalog or skill resource can be requested multiple times by prompt injection and the `skills.list` / `skills.read` tools. Re-fetching adds latency and can make those surfaces observe different remote contents during the same thread. This is a follow-up to #28333: orchestrator skills remain limited to threads without a local executor, and those threads now get a stable per-thread view of the remote skill data they use. ## What changed - Reuse the existing per-thread orchestrator catalog snapshot for `skills.list` and `skills.read` availability checks. - Cache successful orchestrator resource reads by authority, package, and resource so prompt injection and tool calls share the same contents. - Keep the cache memory-only and bounded to 100 resources and 8 MiB per thread. - Leave host and executor skill reads unchanged, and do not cache failed remote reads. ## Verification - Extended the app-server MCP resource integration test to read the same hosted skill resource twice and verify that the remote server receives one read. - The same test verifies that catalog discovery and the selected skill's main prompt are each fetched only once per thread.
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.
