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

Use when writing, modifying, or debugging unit tests (*.test.tsx) in the orchestration cluster webapp (webapp/client/apps/orchestration-cluster-webapp/src/). Covers Vitest browser mode, MSW mocking, and vitest-browser-react rendering.

io.github.camunda/camunda/frontend-migrator

Use when migrating, porting, or rewriting frontend code from operate/client/ or tasklist/client/ to the orchestration cluster webapp. Trigger when migrating legacy pages/components, converting React Router to TanStack Router, replacing MobX with TanStack Query, rewriting styled-components as SCSS, converting legacy tests to Vitest browser mode, or asking how a legacy pattern maps to the new app.

io.github.browserbase/skills/browser-use-to-stagehand

Migrate browser-use (Python) browser-automation scripts to Stagehand v3 (TypeScript) on Browserbase. Use when the user wants to convert, port, rewrite, or migrate a browser-use Agent script to Stagehand, map browser-use features/APIs to Stagehand primitives (act/extract/observe/agent), or move agentic browser automation onto Browserbase with more determinism. Triggers on "browser-use", "browser_use", or "Agent(task=...)".

io.github.PostHog/posthog/writing-tests

Gates whether a new test should exist and forces it to be efficient, protecting CI from low-value test bloat. Use before adding or substantially changing any pytest, Jest, or Playwright test — whenever an agent or engineer is about to write tests for a new feature, bugfix, or PR. Front-loads the value bar (every test must catch a realistic regression no existing test already catches; test behavior through the public interface, not implementation details; collapse near-duplicates into parameterized cases) and the efficiency bar (deterministic, isolated, fast; pick the cheapest test level; Django TestCase over TransactionTestCase; no sleeps, no real network). Includes a "don't write it" decision tree. For fixing an existing flaky test use `/fixing-flaky-tests`; after this gate says a Playwright test is warranted, use `/playwright-test` for mechanics.

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.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".
