What it tells the agent

The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

---
name: test
description: Use when you need to run tests for React core. Supports source, www, stable, and experimental channels.
---

Run tests for the React codebase.

Arguments:
- $ARGUMENTS: Channel, flags, and test pattern

Usage Examples:
- `/test ReactFiberHooks` - Run with source channel (default)
- `/test experimental ReactFiberHooks` - Run with experimental channel
- `/test www ReactFiberHooks` - Run with www-modern channel
- `/test www variant false ReactFiberHooks` - Test __VARIANT__=false
- `/test stable ReactFiberHooks` - Run with stable channel
- `/test classic ReactFiberHooks` - Run with www-classic channel
- `/test watch ReactFiberHooks` - Run in watch mode (TDD)

Release Channels:
- `(default)` - Source/canary channel, uses ReactFeatureFlags.js defaults
- `experimental` - Source/experimental channel with __EXPERIMENTAL__ flags = true
- `www` - www-modern channel with __VARIANT__ flags = true
- `www variant false` - www channel with __VARIANT__ flags = false
- `stable` - What ships to npm
- `classic` - Legacy www-classic (rarely needed)

Instructions:
1. Parse channel from arguments (default: source)
2. Map to yarn command:
   - (default) → `yarn test --silent --no-watchman <pattern>`
   - experimental → `yarn test -r=experimental --silent --no-watchman <pattern>`
   - stable → `yarn test-stable --silent --no-watchman <pattern>`
   - classic → `yarn test-classic --silent --no-watchman <pattern>`
   - www → `yarn test-www --silent --no-watchman <pattern>`
   - www variant false → `yarn test-www --variant=false --silent --no-watchman <pattern>`
3. Report test results and any failures

Hard Rules:
1. **Use --silent to see failures** - This limits the test output to only failures.
2. **Use --no-watchman** - This is a common failure in sandboxing.

Common Mistakes:
- **Running without a pattern** - Runs ALL tests, very slow. Always specify a pattern.
- **Forgetting both www variants** - Test `www` AND `www variant false` for `__VARIANT__` flags.
- **Test skipped unexpectedly** - Check for `@gate` pragma; see `feature-flags` skill.

Questions

What does the test — facebook/react skill do?

The library for web and native user interfaces.

Is test — facebook/react safe to install?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.

What can test — facebook/react access on my machine?

The audit observed no filesystem, network or shell use at all in its source.

How current is this page?

The grade is for one exact copy of the source (55672af85731), read on 2026-10-26. The repository is watched, and a new audit runs when it changes — this is the first audit.
