Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
ansibleSkillansible/vscode-ansible/.cursor/skills/wdio-testing/SKILL.md
Write, run, and debug WebDriverIO (WDIO) UI tests for the Ansible VS Code extension. Use when creating new WDIO specs, fixing test failures, adding webview or Lightspeed tests, or troubleshooting headless/CI execution.
samberSkillsamber/cc-skills-golang/skills/golang-testing/SKILL.md
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`.

BelphemurSkillBelphemur/SoundSwitch/.agents/skills/end-to-end-testing/SKILL.md
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.
FmarzochiReads credentialsSkillFmarzochi/EGC/.agents/skills/e2e-testing/SKILL.md

astronomerSkillastronomer/agents/skills/testing-dags/SKILL.md
Complex DAG testing workflows with debugging and fixing cycles. Use for multi-step testing requests like "test this dag and fix it if it fails", "test and debug", "run the pipeline and troubleshoot issues". For simple test requests ("test dag", "run dag"), the airflow entrypoint skill handles it directly. This skill is for iterative test-debug-fix cycles.
petrkindlmannReads credentialsSkillpetrkindlmann/qa-skills/skills/payment-testing/SKILL.md
Test payment and checkout flows end to end against PSP sandboxes — Stripe first, with the general pattern for Adyen/Braintree/PayPal. Covers Stripe test-mode card numbers and their decline codes, the 3DS/SCA challenge flow and its nested-iframe handling in Playwright, test clocks for subscription/billing-cycle simulation, webhook testing (stripe listen/trigger, signature verification, idempotency), failed/retried payments and refunds, and never using real cards. Use when: "test Stripe checkout," "payment test," "3DS test," "test webhook signature," "test subscription renewal," "test clock," "refund test," "decline card test," "checkout E2E." Not for: General API contract testing of non-payment endpoints — api-testing. PCI-DSS/regulatory compliance audit — compliance-testing. Related: api-testing, playwright-automation, compliance-testing, test-data-management, qa-project-context.
temporalioSkilltemporalio/ui/.claude/skills/auth-testing/SKILL.md
Test OAuth2 token refresh and session expiry locally. Use when working on auth, tokens, SSO, OIDC, or session management features.
nahid-sparktalesSkillnahid-sparktales/agent-dispatcher/skills/quality/e2e-testing/SKILL.md
Build and keep end-to-end suites that are worth their runtime — which journeys belong at this level, selectors that survive refactors, waiting on state instead of sleeping, per-spec data isolation, and flake triage that finds the cause. Use when adding or repairing an e2e suite, when specs are slow or intermittently red, or when deciding whether a case belongs here at all. Not for one-off checking that a change renders, not for unit or integration tests, and not for load testing.

planetis-mSkillplanetis-m/skills/nim-testing/SKILL.md
Write and run deterministic Nim tests, including isolated test files, expected-exception checks, multi-configuration builds, and sanitizer integration. Use when setting up a Nim test suite, testing failure behavior, running tests across debug/release/danger modes, or adding AddressSanitizer support.
BejeweledMeSkillBejeweledMe/codex-pro-agent-skills/skills/qa-testing/SKILL.md
Use when designing, reviewing, validating, debugging, or improving classic software QA strategy and automated test suites. Trigger for autotests, unit tests, integration tests, contract tests, end-to-end tests, test pyramid decisions, flaky tests, test doubles, mocks, fakes, stubs, test coverage, test maintainability, CI/CD quality gates, release validation, exploratory testing, and production feedback for non-LLM software systems.
CaliLukeSkillCaliLuke/skills/skills/ai-testing/SKILL.md
Write robust, maintainable tests. Use when writing unit or integration tests, debugging test failures, or setting up fakes/mocks. Covers test design, assertions, and test doubles.
h0rn3tSkillh0rn3t/golang-skills/skills/go-testing/SKILL.md
Use when writing, reviewing, or improving Go test code — including table-driven tests, subtests, parallel tests, test helpers, test doubles, and assertions with cmp.Diff. Also use when a user asks to write a test for a Go function, even if they don't mention specific patterns like table-driven tests or subtests. Does not cover benchmark performance testing (see go-performance).
fishzjpReads credentialsSkillfishzjp/qa-skills/skills/api-testing/SKILL.md
API testing from OpenAPI/Swagger or case schemas: parameters, boundaries, auth, idempotency, concurrency, error responses, data consistency; runnable scripts; k6 handoff. Not for: Web UI flows, manual case writing. 接口级测试：参数/边界/鉴权/幂等/并发/错误响应/数据一致性，产出脚本与结果；含 k6 压测。不用于：Web UI、手动用例。
mathaixReads credentialsSkillmathaix/OpenClawMachines/.agents/skills/ocm-testing/SKILL.md
Choose and run the smallest safe OpenClaw Machines verification path for backend, frontend, Worker, host enrollment, Firecracker, rootfs, and self-hosted changes.
wekanSkillwekan/wekan/.agents/skills/meteor-testing/SKILL.md
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.

handsontableSkillhandsontable/handsontable/.claude/skills/visual-testing/SKILL.md
Use when writing Playwright visual regression tests or adding a demo route for one - covers the decision rule (what earns a capture, and that a visual spec is in addition to a Playwright assertion), the custom tablePage fixture, the screenshot workflow, reg-suit comparison, and the demo routes in examples/next/visual-tests/

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
