DevolutionsSkill

test-pruner

Devolutions/IronRDP/.agents/skills/test-pruner/SKILL.md

Prune, strengthen, and consolidate tests in a pass of at most one hour, using oracle classification and domain mutants, with cargo-mutants or Stryker.NET where their estimated run fits that hour. Use when asked to remove redundant tests, consolidate tests into cases or properties, audit test value, clean up AI-written tests, finalize a change's tests before its pull request opens, or get a mutation-backed review of a pull request's tests. For a quick oracle-only check, use `test-oracle-reviewer` instead.

callstackSkill

react-native-testing

callstack/react-native-testing-library/skills/react-native-testing/SKILL.md

Write tests using React Native Testing Library (RNTL) v13 and v14 (`@testing-library/react-native`). Use when writing, reviewing, or fixing React Native component tests. Covers: render, screen, queries (getBy/getAllBy/queryBy/findBy), Jest matchers, userEvent, fireEvent, waitFor, and async patterns.

Triggers on: test files for React Native components, RNTL imports, mentions of "testing library", "write tests", "component tests", or "RNTL".

openstackSkill

neutron-testing-patches

openstack/neutron/.agents/skills/neutron-testing-patches/SKILL.md

Create temporary DNM patches that stress-test Zuul CI jobs or individual tests by running them multiple times. Covers strategies for duplicating Zuul jobs, duplicating test classes/methods, modifying tox regexes, and repeating tests with stestr. Use when the user asks to create a testing patch, stress-test a CI job, run a test multiple times, or debug flaky tests.

samugit83Skill

redamon-testing

samugit83/redamon/skills/redamon-testing/SKILL.md

How RedAmon tests actually run and how to author them: the per-file Docker gate, the unit/integration/live tiers, and the failure modes that make a green run a lie. Trigger: editing any test_*.py, *.test.ts(x) or tests/*.sh; a test that is red, skipped or xfailed; a request to "run the tests", "make it green" or check coverage; editing redamon.sh cmd_test, tooling/scripts/pytest_isolated.py, any conftest.py or any pytest.ini.

Agenta-AISkill

test-design

Agenta-AI/agenta/.agents/skills/test-design/SKILL.md

Decide what to test and how to write the tests for a frontend change. Use before you write or review unit tests for web/mobile or the @agenta/* packages, when you fix a bug and add a regression test, and before you say a change is tested. Gives the risk list, the rules for each test, and the mutation check.

ethereumSkill

run-tests

ethereum/consensus-specs/.claude/skills/run-tests/SKILL.md

Run tests and generate reference tests. All testing goes through `make test`, never `pytest` directly. Always load this skill before running tests.

medplumSkill

test-compactor

medplum/medplum/.agents/skills/test-compactor/SKILL.md

Cut the tests a diff adds down to the ones that each catch a bug no other test catches, and tighten the survivors. Use after tests pass and before comment-compactor, `git push`, or `gh pr create`. Also use when asked to "trim the tests", "dedupe the tests", "compact the tests", or when a review says a PR has too many, redundant, or overly long tests.

podman-desktopSkill

playwright-testing

podman-desktop/podman-desktop/.agents/skills/playwright-testing/SKILL.md

Guide for writing, updating, and maintaining Playwright end-to-end tests for Podman Desktop using the project's Electron runner, custom fixtures, and Page Object Model hierarchy. Use when creating new E2E spec files, building or modifying page objects, updating the test framework or utilities, debugging test failures, adding smoke tests, or when the user asks about Playwright tests, test automation, spec files, page models, or the E2E test structure.

projenSkill

projen-testing-review

projen/projen/skills/projen-review/projen-testing-review/SKILL.md

projen testing reviewer. Use on any projen pull request that changes behavior in `src/**`, `projenrc/**` or `scripts/integ-*.sh`, or adds or changes tests in `test/**`: a feature or fix whose main effect no test would catch breaking, tests that run the code but assert nothing that would catch it, hand-rolled test setup where `synthSnapshot` / `Testing.synth` / `TestProject` / `withProjectDir` / `mkdtemp` already exist, packaged-artifact behavior tested in Jest instead of `scripts/integ-*.sh`, and snapshot tests whose name or file does not match what they snapshot.

kubernetes-sigsSkill

test-pyramid

kubernetes-sigs/agent-sandbox/.agents/skills/test-pyramid/SKILL.md

Analyze the repo's unit and E2E tests and propose rebalancing toward a test pyramid — which E2E tests (or assertions inside them) can be covered by unit tests, which unit-level gaps genuinely need E2E coverage, and where coverage is duplicated. Use when the user asks about test pyramid, test rebalancing, "should this be an e2e or unit test", E2E-to-unit migration, or slow/flaky E2E suites that might shrink.

cockroachdbSkill

skip-test-with-issue

cockroachdb/cockroach/.claude/skills/skip-test-with-issue/SKILL.md
