adams-oai 28cade4f5a Cache empty remote skill discovery with filesystem watches (#57598)
## Why

Repeated repository skill discovery performs remote metadata requests even when no `.agents/skills` directories exist. Reuse verified empty results to avoid those round trips while watching for changes that require a new scan.

## What changed

- Add the Linux executor capability `fs_watch_missing`, the `fs/watchMissing` request, and `fs/missingChanged` notifications.
- Register watches in the background and reuse empty results only after the executor acknowledges coverage. Key reuse by filesystem, working directory, and project root markers.
- Invalidate observations on relevant filesystem or mount changes, watch supersession, or connection loss. Clear cached observations on forced reloads and cache resets.
- Retain live discovery while registration is pending or watching is unsupported, unavailable, or cannot verify the observation.

## Testing

Add tests for empty-result reuse and invalidation, skill directory creation before watch acknowledgement, unsupported executors, idle WebSocket notifications, reconnection, case aliases, and bind mounts and unmounts. Include an ignored manual latency comparison for repeated empty remote scans.

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

Codex CLI splash


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"

The standalone installers download from https://releases.openai.com/codex by default and fall back to GitHub Releases if a metadata or asset download is unavailable. To force GitHub Releases, set CODEX_INSTALLER_USE_RELEASES_OPENAI_COM to false (0 and no are also accepted):

curl -fsSL https://chatgpt.com/codex/install.sh | CODEX_INSTALLER_USE_RELEASES_OPENAI_COM=false sh
$env:CODEX_INSTALLER_USE_RELEASES_OPENAI_COM='false'; 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
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

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.

Using Codex with your ChatGPT plan
