jif a18de1f3b6 guardian: isolate review context from skills and memories (#28285)
## Why

Guardian reviews embed the parent session transcript as untrusted
evidence. Skill or plugin mentions in that transcript must not be
interpreted as requests to inject more instructions into the Guardian
request, and memory context adds unrelated model-visible context to an
approval decision.

Keeping those sources out of the nested review session makes the request
smaller and preserves the trust boundary around the transcript being
assessed.

## What changed

- Skip skill and plugin discovery when building turns for Guardian
reviewer sessions.
- Disable memory context and dedicated memory tools in the derived
Guardian configuration.
- Extend the Guardian request-layout coverage to verify that a `$skill`
mention remains visible only as transcript evidence while neither the
skill body nor memory context is injected.
- Expand the Guardian configuration test to cover the disabled memory
settings.

## Testing

- Updated the Guardian review request snapshot and assertions for skill
and memory isolation.
- Extended the Guardian session configuration test to cover memories.

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"

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
