Agent Skills
Agent Skills are instruction packages that teach an AI coding assistant how to write and run test automation on TestMu AI. Install one, and your assistant works like an SDET who already knows that framework's project layout, dependency versions, cloud execution config, and CI wiring.
Each skill is open source and framework-specific. A skill covers one framework or platform, so the agent uses that tool's own idioms instead of generic automation code. The full set lives in the TestMu AI Agent Skills repository.
Skills work with Claude Code, GitHub Copilot, Cursor, Gemini CLI, and any assistant that loads custom skills.
How to Install a Skill
Testing an AI agent with Rook? Its skill is distributed from the public Rook repository, separately from the framework skills below. Follow the Rook coding-agent setup guides for Claude Code, Codex, Gemini CLI, GitHub Copilot CLI, OpenCode, Cursor CLI, Antigravity CLI, VS Code, Windsurf, or Antigravity IDE. The Rook skill installer is npx @testmuai/rook-skill@latest for Claude Code, Codex, and Gemini CLI; the other guides use manual project installation. Install Rook CLI separately.
Use the agentskillsforall installer to add a skill straight from the repository. No manual cloning is required.
- Install a specific skill
- Browse all available skills
Add skills by name. Run the installer once per skill you want:
npx agentskillsforall add https://github.com/LambdaTest/agent-skills.git --skill selenium-skill
npx agentskillsforall add https://github.com/LambdaTest/agent-skills.git --skill playwright-skill
npx agentskillsforall add https://github.com/LambdaTest/agent-skills.git --skill cypress-skill
List every skill in the repository, then install the one you want:
npx agentskillsforall list https://github.com/LambdaTest/agent-skills.git
Once installed, ask your assistant to write and run tests. It picks up the matching skill automatically.
Core Skills by Framework and Platform
Pick the skill for the framework you already test in. Each card opens that skill's source on GitHub. Web frameworks run on the TestMu AI browser grid, and app frameworks target real Android and iOS devices.
Selenium
WebDriver tests that run on the TestMu AI browser grid.
Cypress
End-to-end specs that run locally and on the cloud.
Playwright
Cross-browser tests with fast cloud execution.
Puppeteer
Headless Chrome automation on the TestMu AI cloud.
Appium
One suite for real Android and iOS devices.
Espresso
Native Android UI tests with Espresso.
XCUITest
Native iOS UI tests with XCUITest.
Flutter
Widget and integration tests for Flutter apps.
Skills That Ship With a Product
Two TestMu AI products publish their own skill packages with a one-command installer. They are not part of the agentskillsforall catalog above, so install them directly (Node.js 22+):
| Product | What the skill does | Install |
|---|---|---|
| Rook | Tests, red-teams and regression-checks an AI agent you own, then reads the evidence-backed verdicts. Works with Claude Code, Codex and Gemini CLI. | npx @testmuai/rook-skill |
| Kane CLI | Natural-language browser automation from your coding agent. | npx @testmuai/kane-cli-skill |
Rook's skill source, references and user guide live in the LambdaTest/rook repository.
Explore the Full Skill Catalog
The 12 skills above are the most common starting points. The repository ships 70+ skills across eight testing categories.
Beyond web and mobile, it covers BDD (Cucumber, Behave, SpecFlow), unit testing (Jest, Pytest, JUnit 5, TestNG), and API testing (Postman, Newman, OpenAPI). List everything with npx agentskillsforall list, or browse the full skill catalog on GitHub.
