io.github.addyosmani/agent-skills/browser-testing-with-devtools

Tests in real browsers via Chrome DevTools MCP. Use when building or debugging anything that runs in a browser. Use when you need to inspect the DOM, capture console errors, analyze network requests, profile performance, or verify visual output with real runtime data. Requires the chrome-devtools MCP server to be configured.

io.github.comet-ml/opik/writing-e2e-tests

Use when a developer wants to add, write, or create an end-to-end test for an Opik feature, page, or branch — e.g. "add an e2e test for the experiments comparison page", "write a test for the feature I just built", "e2e test for this branch", "cover the dataset items flow with a test". Runs the full loop in tests_end_to_end/e2e/ — analyze the feature and frontend code, explore the live UI with the Playwright MCP, write the Page Object Model + spec, and run it locally until green.

io.github.nexu-io/open-design/agent-browser

Browser automation CLI for AI agents. Use when the user needs to inspect, test, or automate browser behavior: navigating pages, filling forms, clicking buttons, taking screenshots, extracting page data, reading selected Open Design browser-tab context, testing web apps, dogfooding Open Design previews, QA, bug hunts, or reviewing app quality. Prefer local Open Design preview URLs unless the user explicitly asks for external browsing.

io.github.rustfs/rustfs/security-advisory-lessons

Apply RustFS security lessons distilled from repository GitHub Security Advisories. Use when making or reviewing RustFS code changes, doing security checks, handling PR review for auth/authz, IAM, storage, RPC, logging, CORS, console/browser, encryption, policy, or endpoint changes, and when deciding which security regression tests are required.

io.github.pierrecomputer/pierre/testing-and-verification

Use when adding or running tests, checking snapshots, choosing between Bun tests and Playwright, running lint/format/typecheck, or deciding the verification scope for a change.

io.github.camunda/camunda/frontend-unit-test

Use when writing, modifying, or debugging unit tests in the orchestration cluster webapp at webapp/client/apps/orchestration-cluster-webapp/. Use when working with Vitest browser mode, MSW mocking, vitest-browser-react rendering, or any *.test.tsx file in the OC webapp's src/ directory. Trigger whenever someone needs to create, fix, or understand a frontend unit test in webapp/client/.

io.github.camunda/camunda/frontend-migrator

Use when migrating, porting, rewriting, or moving frontend code from operate/client/ or tasklist/client/ to the orchestration cluster webapp at webapp/client/apps/orchestration-cluster-webapp/. Trigger whenever someone mentions migrating a legacy page, component, or module to the new unified frontend, converting React Router to TanStack Router, replacing MobX stores with TanStack Query or URL state, rewriting styled-components as SCSS modules, or converting legacy test patterns to Vitest browser mode. Also use when someone asks how a legacy pattern maps to the new architecture, even for small questions like "how would I write this Operate component in the new app?" or "what's the equivalent of this Tasklist store in the unified frontend?"

io.github.bluesky-social/atproto/testing

Testing practices for this monorepo — choosing between unit and end-to-end tests, where test files live, how tsconfig.test.json fits in, how to drive Playwright, to to write/adapt UI/end-to-end tests, and which test runner (vitest vs jest) to use. MUST be invoked BEFORE any code search or file reads whenever the user asks to add, write, or extend a test, add coverage, create a test file, set up testing in a new package, mentions vitest/jest, or refers to an existing `*.test.ts` file. Applies equally to unit tests and to end-to-end / UI tests — the skill routes to a Playwright-MCP-first discovery flow for the latter, which differs from normal code-search workflow.

io.github.eduhub-org/eduhub/cursor-browser

Inspect UI via cursor-ide-browser (Cursor Browser tab); fall back to user-playwright if internal browser MCP is unavailable. Use for @Browser, open tab, layout checks, localhost — or when user explicitly asks for Playwright.

io.github.different-ai/openwork/browser-automation

Local OpenWork Electron browser automation with CDP. Use when driving a local Electron dev app, browser_list, browser_snapshot, browser_eval, composer automation, or local UI smoke tests.

io.github.langfuse/langfuse/frontend-browser-review

Shared workflow for browser-based review of user-visible frontend changes in Langfuse. Use when a change affects UI behavior, layout, styling, navigation, or browser-visible regressions and should be checked with the Playwright MCP server before signoff.

io.github.openclaw/openclaw/browser-automation

Use when controlling web pages with the OpenClaw browser tool, especially multi-step flows, login checks, tab management, or recovery from stale refs/timeouts.

io.github.chromium/chromium/test-conversion-reviewer

Reviewer for converting unit tests to browser tests for Project Bedrock. Invoke this when the user needs to review their work while removing complex Browser dependencies from tests.

io.github.agent0ai/agent-zero/browser-form-workflows

Use for complex Agent Zero Browser form workflows involving selects, checkboxes, radios, file uploads, contenteditable fields, multi-step validation, or visually verified submission.

io.github.agent0ai/agent-zero/browser-automation

Use for complex Agent Zero browser automation, including multi-tab browsing, screenshots, forms, uploads, raw pointer/keyboard actions, host-vs-container browser mode, and visual verification workflows.

io.github.kdlbs/kandev/mobile-parity

Ensures UI feature work ships with desktop and mobile parity, responsive behavior, and mobile Playwright E2E coverage. Use when implementing, planning, reviewing, or testing any new feature, page, component, workflow, form, dialog, sidebar, navigation, dashboard, or visual UI change; if work touches frontend or user-facing UI, this skill must run even when user mentions only desktop or says "new feature".

io.github.paperclipai/paperclip/agent-browser

Drive a real browser to inspect or interact with a web page or app — navigate, take screenshots, read console and network, fill simple forms — for verification tasks, not unattended automation.

io.github.jxxghp/MoviePilot/browser-use

Use this skill when the user asks the agent to open, browse, inspect, extract content from, click through, fill forms on, screenshot, or verify a web page with a browser. Also use it for MoviePilot scenarios that need browser interaction, such as checking a site page, confirming a JavaScript-rendered result, testing login state, capturing visible errors, or updating and validating tracker site cookies.

io.github.affaan-m/ECC/react-testing

React component testing with React Testing Library, Vitest/Jest, MSW for network mocking, accessibility assertions with axe, and the decision boundary between component tests and Playwright/Cypress end-to-end runs. Use when writing or fixing tests for React components, hooks, or pages.

io.github.actualbudget/actual/review-actual-pr

Comprehensive review of a pull request in the actualbudget/actual repo. Performs an offline code review against the repo's CODE_REVIEW_GUIDELINES.md and AGENTS.md (no GitHub comments are ever posted), then browser-tests the change with playwright-cli. For bug PRs, reproduces the issue on edge.actualbudget.org first and verifies the fix on the Netlify preview; for feature/enhancement PRs, exercises the change on the preview and captures annotated screenshots highlighting the new functionality. Use whenever the user asks to review, test, validate, vet, sanity-check, QA, or otherwise look at a PR / pull request in the Actual Budget repo — including phrases like "review

io.github.camunda/camunda/frontend-integration-test
