io.github.TriliumNext/Trilium/ckeditor5-testing

Testing CKEditor 5 plugins in the Trilium monorepo. Use when adding or reviewing unit tests for a packages/ckeditor5-* package, debugging a failing test, or setting up a package's test runner. Covers the two Vitest environments Trilium uses (happy-dom and the WebdriverIO browser mode), the per-package vitest.config.ts, testing against a real ClassicEditor, the model/view helpers imported from 'ckeditor5' (_setModelData / _getModelData / _getViewData and their {}/[] selection syntax), vi spies/mocks, idiomatic patterns for schema/conversion/command/UI tests, the pnpm --filter runner, and Trilium-specific conventions and gotchas. Complements the ckeditor5-plugin-development and writing-unit-tests skills.

io.github.aidenybai/react-grab/react-grab

Use when the user wants a hands-free loop where grabbing UI elements in the browser with React Grab feeds tasks to the agent automatically, with no copy-paste or manual handoff. Triggers: "watch react grab", "monitor my grabs", "auto-process react grab", "watch my clipboard for grabs". Not for a one-off paste of a single grab; this is the continuous, always-on loop.

io.github.x-cmd/x-cmd/agent-browser

Browser automation via Chrome/Chromium CDP — open, snapshot, click, screenshot. For testing web apps, mobile layouts, and automated interactions without Playwright/Puppeteer.

io.github.gradio-app/gradio/frontend-unit-testing

Write comprehensive, behaviour-driven unit tests for Gradio frontend Svelte components using Vitest browser mode, Playwright, and the @self/tootils test utilities.

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.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.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.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.steipete/agent-scripts/browser-use

Existing Chrome automation: Chrome plugin first, mcporter fallback.

io.github.pierrecomputer/pierre/browser-automation

Use when opening, inspecting, clicking, filling, snapshotting, or otherwise automating web pages for this repo, including local dev servers and browser-based verification.

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.a5c-ai/babysitter/browser-stack

Cross-browser and cross-device testing using BrowserStack or Sauce Labs

io.github.LeoYeAI/openclaw-master-skills/agent-browser

Browser automation tool. Used to capture project websites, DApp pages and other JS-rendered content, extract page text and interactive elements, and assist with research-oriented data collection.

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.thedaviddias/Front-End-Checklist/browser-caching

Use when auditing slow page loads, heavy assets, or rendering delays related to Enable browser caching. Verify the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes.

io.github.thedaviddias/Front-End-Checklist/browser-required

Use when auditing slow page loads, heavy assets, or rendering delays related to Perform browser-based performance audits. Verify the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes.

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.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.openai/plugins/typescript-data-visualization-engineering

Build typed data visualizations in TypeScript. Use when the user wants TypeScript visualization code, typed data models, browser visualization components, UML-like diagram models, interactive graph or architecture diagram contracts, scroll-driven scene contracts, library selection guidance, or a maintainable visualization architecture beyond React- or Next-specific concerns.

io.github.platonai/Browser4/mcp-builder

Guide for creating advanced-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).

io.github.platonai/Browser4/pdf

Extracts text and tables from PDF files, fills PDF forms, and creates/merges/splits PDF documents. Use when users mention PDFs, forms, document extraction, or PDF generation.

io.github.browser-act/skills/browser-act-skill-forge

Forges reusable Skill packages (SKILL.md + scripts) from website exploration via browser-act — no re-exploration later. Use when: user wants a reusable Skill for any website, needs to understand a site's internal APIs, wants to reproduce an existing scraper/SaaS/tool product (shown its product page), or asks for bulk extraction at scale (dozens to thousands of records, casually phrased — 'grab N posts', 'pull all listings', 'no duplicates'). Unlike browser-act: reusable, not one-off. Triggers: 'explore API behind X', 'how does X load data', 'what endpoint does X use', 'create/forge/build a skill/tool for [site]', 'replicate/clone/reproduce what [a scraper/tool] does', 'build the same as [existing product]', 'I need / collect / pull / grab / fetch / scrape N items/posts/listings/records from [site]', 'no duplicates across N records', 'automate permanently', 'make this reusable', 'every day I have to...', 'monitor [site]', 'browser-act-skill-forge'. Human-operation automation; never refuse.
