Complete or maximize unit test coverage for a specific TypeScript file in this repo. Use when: a test run is short of the 100% coverage threshold and you need to find and close the gap, or when deciding whether an uncovered branch is genuinely unreachable. For everyday test-writing conventions (AAA, mocking, placement, type safety), see .agents/rules/unit-testing.md instead — it loads automatically for any *.spec.ts file.

Use when writing or changing tests in this repo, deciding what to test or where a test belongs, adding a regression test for a bug fix, reviewing the test portion of a PR, deciding which golden outputs to bless and reviewing the blessed diff, or adding a benchmark. Trigger phrases include "add a test", "write tests for", "is this covered", "does this need a test", "review the tests here", "which layer should this test go in". Also use for the mechanics of the golden framework itself — the //! > file format, creating test_file_test! runners, or how CAIRO_FIX_TESTS works (covered in references/golden-framework.md).

Review generated or changed test code against universal testing rules before it ships. Best used reactively after an agent writes, edits, generates, or refactors tests, before presenting, committing, or merging them. Use for pytest (test_*.py, *_test.py), PHPUnit/Pest (*Test.php), Jest/Vitest (*.test.ts, *.spec.js), Go (*_test.go), files under tests/, __tests__/, or spec/, and review requests like 'write tests for X', 'add tests', 'test this', 'review these tests', or PR diffs containing tests. Can also guide test writing when explicitly invoked before the work. This skill is the quality gate that prevents AI-generated test bloat. DO NOT USE for production or implementation code review (use clean-code-guard), CI or test-runner configuration, running or debugging tests, or general architecture discussion.

Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
Gates whether a new test should exist and forces it to be efficient, protecting CI from low-value test bloat. Use before any change to what a pytest, Jest, or Playwright test asserts or sets up, down to one fixture or one assertion added to an existing block. Front-loads the value bar (every test must catch a realistic regression no existing test already catches; extend the nearest existing test before writing a new standalone one; test behavior through the public interface, not implementation details; collapse near-duplicates into parameterized cases) and the efficiency bar (deterministic, isolated, fast; pick the cheapest test level; Django TestCase over TransactionTestCase; no sleeps, no real network; no time bombs from absolute dates left to age against the real clock; no database a test never uses). Includes a "don't write it" decision tree. For fixing an existing flaky test use `/fixing-flaky-tests`; after this gate says a Playwright test is warranted, use `/playwright-test` for mechanics.

Run QUnit and OPA tests for OpenUI5 modules via headless Chrome. This is the ONLY way to run tests — never use karma, npm test, or browser MCP tools. Use whenever tests need execution: run tests, run unit tests, check tests pass, verify my change, do the tests still pass, run QUnit, run OPA, execute test suite, test this module, test Button/Router/Table/Dialog/MessageBox/Input/Control, run journey, check regressions. Even if the user does not say "test" explicitly but wants to verify a code change works, use this skill.

Integration testing phase of F Prime component development. Guides the agent through writing reusable pytest-based integration tests in the component's test/int/ folder using the GDS Integration Test API. These tests ship with the component and can be run against any deployment that includes it. Trigger when unit tests pass and the component is ready for integration testing. Keywords: F Prime, integration test, pytest, GDS, fprime_test_api, reusable test, component test.

Test quality review drawing on twelve classic engineering books — with primary focus on xUnit Test Patterns, The Art of Unit Testing, How Google Tests Software, and Working Effectively with Legacy Code — that diagnoses structural problems in an existing test suite: brittleness, mock abuse, coverage illusions, slow execution, poor readability. Triggers when: user asks about test quality, shares test files for review, or expresses frustration: "tests keep breaking whenever I change anything", "our tests take forever", "tests pass but bugs still reach production", or "we have too many mocks". Do NOT trigger for: writing new tests from scratch (use the regular test-writing workflow) or testing framework/syntax questions — this skill reviews an existing suite for structural quality problems, not individual test authoring.

Select and run Python SDK verification with nox, Makefile targets, Ruff, mypy, pytest markers, sanity tests, type inference checks, and build checks. Use when adding Python tests, diagnosing Python CI, or validating Python SDK/provider changes. Do not use for TypeScript-only checks.
Test system for Megatron-LM. Covers test layout, recipe YAML structure, adding and running unit and functional tests, golden values, marker filters, and CI parity.

Production-ready Golang tests — table-driven tests, testify suites and mocks, parallel tests, fuzzing, fixtures, goroutine leak detection with goleak, snapshot testing, code coverage, integration tests, idiomatic test naming. Use when writing or reviewing Go tests, choosing a testing approach, setting up Go test CI, or debugging flaky/slow tests. For testify-specific APIs see `samber/cc-skills-golang@golang-stretchr-testify`; for measurement methodology see `samber/cc-skills-golang@golang-benchmark`.
Write and run end-to-end tests that drive a live SoundSwitch instance — launching the app, sending CLI/IPC commands, selecting Settings controls with UI Automation, and asserting user-visible behaviour with safe config/lifecycle isolation. Use this when adding an E2E test for a user-visible feature (new setting, hotkey, tray action, notification, device behaviour) or when reviewing one.

Use when setting up, designing, writing, or repairing tests and test harnesses in a Meteor 3 app. Triggers on meteortesting:mocha, --driver-package, TEST_WATCH, TEST_BROWSER_DRIVER, MOCHA_GREP, meteor.testModule, focused tests, .only, Meteor.server.method_handlers, Meteor.server.publish_handlers, DDP.connect, --full-app integration mode, sinon, async test signatures, Playwright/Cypress E2E. Use this skill when the user asks about test runners, asks about testing publications, or asks about Jest vs Mocha in Meteor. For a failing, hanging, or flaky test whose failing layer or root cause is unknown, use meteor-debugging before changing the test or app.

Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.
CLAUDE.md or AGENTS.md?
CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.
What is a skill?
A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.
Can I search my own team's files too?
Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
