next-partial-prefetching-adoption
by vercel
Turn on Partial Prefetching in a Next.js app and work through the insights it surfaces. Use when the user wants to enable or adopt Partial Prefetching, flip the partialPrefetching flag, opt routes in with export const prefetch = 'partial', audit Link prefetch={true} behavior, preserve existing prefetched UI with instant() tests, or resolve the instant-link-prefetch-partial and instant-shell-url-data insights.
gate-tests
by vercel
How to use the @gate / @force-gate test directives instead of it.skip or fake-green skip patterns. Use when a test is known-failing under some test-matrix dimension (dev mode, a bundler, an experimental flag like cacheComponents), when converting if (isNextDev) return guards or env-var describe.skip branches, when adding a condition to test/lib/gate/conditions.ts, or when keying a fixture's experimental flag on a __NEXT_TEST_AXIS letter. Covers directive choice, condition tiers, the test-axis fixture pattern, pitfalls, and verification commands.
router-act
by vercel
How to write end-to-end tests using createRouterAct and LinkAccordion. Use when writing or modifying tests that need to control the timing of internal Next.js requests (like prefetches) or assert on their responses. Covers the act API, fixture patterns, prefetch control via LinkAccordion, fake clocks, and avoiding flaky testing patterns.
next-dev-loop
by vercel
Verify Next.js runtime behavior after editing app code. Use this skill to confirm a change actually works in a running app — not just that it compiles or type-checks. Combines /_next/mcp (Next.js's view) with agent-browser (the browser's view). Requires a running next dev.
ha-quality-scale-verify
by home-assistant
Verifies that a Home Assistant integration follows a specific quality scale rule, checking whether it implements the required patterns, configurations, or code structures defined by the quality scale system. Use when asked to check a rule (e.g. "check if the peblar integration follows the config-flow rule") or to verify an integration reaches a quality tier (Bronze, Silver, Gold, Platinum).
discovering-make-commands
by streamlit
Lists available make commands for Streamlit development. Use for build, test, lint, or format tasks.
react-testing
by getsentry
Write and review React/TypeScript tests for Sentry's frontend using Jest and React Testing Library. Use when adding or editing tests in static/ (*.spec.tsx), writing component/hook tests, mocking API responses with MockApiClient, testing routing or network requests, or when asked to "write a frontend test", "add a React test", "test this component", or "fix a flaky RTL test".
writing-bundler-tests
by oven-sh
Guides writing bundler tests using itBundled/expectBundled in test/bundler/. Use when creating or modifying bundler, transpiler, or code transformation tests.
writing-dev-server-tests
by oven-sh
Guides writing HMR/Dev Server tests in test/bake/. Use when creating or modifying dev server, hot reloading, or bundling tests.
scout-migrate-from-ftr
by elastic
Single entry point for migrating Kibana Functional Test Runner (FTR) tests to Scout. Plans the migration first, asks the user to review the plan, then executes it and runs the new tests. Use when migrating FTR tests to Scout, triaging FTR suites for Scout readiness, deciding UI vs API vs RTL/Jest, mapping FTR services/page objects/hooks to Scout fixtures, or splitting loadTestFile patterns.
branch-readiness-checks
by elastic
"Validate branch readiness before push or PR using base-diff and local-change checks."
scout-create-scaffold
by elastic
Generate or repair a Scout test scaffold for a Kibana plugin/package (test/scout*/{api,ui} Playwright configs, fixtures, example specs). Use when you need the initial Scout directory structure; prefer node scripts/scout generate with flags for non-interactive/LLM execution.
enzyme-to-rtl
by elastic
Migrate Enzyme tests to React Testing Library (RTL). Use when converting shallow/mount enzyme tests to RTL render, replacing enzyme selectors with RTL queries, updating snapshot tests, or when the user mentions enzyme migration, RTL migration, or react-testing-library.
scout-best-practices-reviewer
by elastic
Review Scout UI/API tests (including Scout test migrations) for best practices, reuse, parity, and server config hygiene.
workflows-management-jest-testing
by elastic
Use the shared TestProvider in workflows_management Jest tests instead of hand-wiring KibanaContextProvider, QueryClientProvider, WorkflowsContextProvider, MemoryRouter, I18nProvider, and the Redux Provider. Use when writing or updating React/Jest tests under src/platform/plugins/shared/workflows_management/public/**, rendering components or hooks that touch Kibana services, the Redux store, react-query, routing, or i18n.
cypress-to-scout-migration
by elastic
Migrate Kibana Cypress E2E tests (.cy.ts) to Scout (Playwright). Applies to any Kibana plugin or solution. Includes triage gates (duplicate detection, layer analysis, value assessment), Cypress-to-Scout pattern mapping, data cleanup audit, and PR workflow. Use when: (1) migrating a Cypress test to Scout, (2) converting .cy.ts to .spec.ts, (3) planning a Cypress-to-Scout migration batch, (4) rewriting Cypress screens/tasks as Scout page objects, (5) asked "how do I move this Cypress test to Scout/Playwright", (6) asked about differences between Cypress and Scout.
evals-write-spec
by elastic
Write LLM evaluation spec files with datasets, tasks, and evaluators using the @kbn/evals Playwright fixture. Use when authoring new eval specs, adding datasets or evaluators, or debugging evaluation test failures.
