# test output preview
## PART A: Task fit
- Use case: Use when you need to run tests for React core. Supports source, www, stable, and experimental channels. Run tests for the React codebase. Release Channels: Common Mistakes: runs entirely locally. Works with Claude Code, Cursor, Cline and 23 more..
- Inputs: target material, constraints, expected output, and acceptance criteria.
- Evidence boundary: follow “Decide Fit First / Design Intent / How To Use It” and do not present inference as author intent.
## PART B: Execution result
- **01** The card summarizes the use case; runtime output centers on “Use when you need to run tests for React core. Supports source, www, stable, and experimental channels. Run tests for the React codebase. Release Channels: Common Mistakes: runs entirely locally. Works with Claude Code, Cursor, Cline and 23 more.”.
- **02** When the source has headings, the agent prioritizes “Decide Fit First / Design Intent / How To Use It” so the result follows the author’s structure.
- **03** Typical output includes task judgment, concrete steps, required commands or file edits, validation, and follow-up options.
- **04** Risk context follows the fingerprint: read files, write/modify files; mostly runs locally; usually needs no extra API key.
## Running Rules
- read files, write/modify files; mostly runs locally; usually needs no extra API key.
- Validate with a small sample before expanding scope.
- Return the result, validation criteria, and next iteration options. The source mentions slash commands such as `/test`; use them first when your agent supports command triggers.
Name target files or source material, expected output, forbidden changes, and whether network or shell access is allowed. Permission fingerprint: read files, write/modify files.
Start with a small task and check whether the result follows “Decide Fit First / Design Intent / How To Use It”. Inspect diffs, logs, previews, or tests before expanding scope.
Confirm the final output includes a concrete result, evidence, and next action. If it stays generic, tighten inputs, boundaries, and acceptance criteria.

# test
## When to use
- Use when you need to run tests for React core. Supports source, www, stable, and experimental channels. Run tests for…
- Use it when the task has clear inputs, repeatable steps, and validation criteria.
## What to provide
- Target material, scope, expected result, and forbidden changes.
- Whether network, commands, file writes, or external services are allowed.
## Execution rules
- Organize steps around “Decide Fit First / Design Intent / How To Use It” and keep inference separate from source facts.
- read files, write/modify files; mostly runs locally; usually needs no extra API key.
- Validate with a small sample before expanding the task.
## Output requirements
- Return the deliverable, key evidence, validation method, and next action.
- Mark missing information as unknown; do not invent commands, platforms, or dependencies. The author source anchors workflow facts; repository files anchor sources and commands; Fluxly only adds fit, limitations, and quality judgment.
skill "test" {
input -> user goal + target files + boundaries + acceptance criteria
context -> Decide Fit First / Design Intent / How To Use It
rules -> SKILL.md triggers / order / output contract
runtime -> no special runtime | read files, write/modify files | mostly runs locally
guardrails -> usually needs no extra API key + small-sample validation + diff/log review
output -> copyable result + checklist + next iteration
} 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 defaultsexperimental- Source/experimental channel with EXPERIMENTAL flags = truewww- www-modern channel with VARIANT flags = truewww variant false- www channel with VARIANT flags = falsestable- What ships to npmclassic- Legacy www-classic (rarely needed)
Instructions:
- Parse channel from arguments (default: source)
- 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>
- (default) →
- Report test results and any failures
Hard Rules:
- Use --silent to see failures - This limits the test output to only failures.
- 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
wwwANDwww variant falsefor__VARIANT__flags. - Test skipped unexpectedly - Check for
