Browse reusable Agent Skills, each with a clear purpose and practical guidance.
Use when working with Turso yield injection or synthetic failure injection machinery for safe resumable state-machine boundaries, including YieldInjector, FailureInjector, YieldPointMarker, inject_transition_yield!, inject_io_yield!, inject_transition_failure!, CommitYieldPoint, CheckpointYieldPoint, CursorYieldPoint, deterministic interleaving tests, abandoned statement/commit tests, and concurrent-simulator yield plans.
Use when the user says 'no hallucinations', 'verify APIs', 'reality check', or 'don't invent functions'. Prevents the agent from calling methods, imports, or variables that do not provably exist in the user's installed version.
Run RustPython tests in Apple's `container` CLI Linux environment. Use when user asks to run or compare Linux test results on macOS.
Validate releases and release links: URL liveness, file hashes, CDN latest.version files, and aka.ms redirect targets. Uses release-notes verify and generate commands against the local release-notes directory. USE FOR: validate the latest release, validate release links, validating that all download links return HTTP 200, verifying SHA512 hashes match downloaded content, checking CDN latest.version files match releases.json, checking aka.ms redirects point to the correct download URLs, regenerating releases-index.json and releases.md after source data changes. DO NOT USE FOR: editing releases.json or release.json (edit source data directly), graph regeneration (use update-release-graph skill), supported-os changes (use update-supported-os skill).
Use when testing a local or public URL on a real device via BrowserStack, opening a live browser session on Android, iOS, or desktop browsers, or when the user mentions BrowserStack, real device testing, mobile testing, cross-browser testing, touch testing, or wants to verify behavior on a specific phone, tablet, or browser version. Also trigger when the user says "test this on Android/iPhone/Safari/Chrome mobile", asks to open a live session, or mentions demo-mobile.html, even if they don't mention BrowserStack by name.
Use when working with row or column indexes in Handsontable - translating between physical, visual, and renderable coordinates, using IndexMapper, or debugging index-related bugs where rows or columns appear in wrong positions
Use when creating a demo or test page for manual testing of Handsontable. Trigger when the user asks to create a demo, test page, repro page, reproduction case, manual test, or wants to verify a bug fix or feature visually. Also trigger when the user mentions dev-generated.html, dev-pr.html, dev-latest.html, dev.html, or wants to compare behavior between a released version and a local build. Use this for any PR that needs a manual testing artifact.
Use when reviewing changed or staged code, a branch, or a PR in the Handsontable monorepo across architecture, code quality, performance, and accessibility. Covers SOLID / Law of Demeter / plugin decoupling / breaking-changes policy, custom ESLint rules / JSDoc / naming / cognitive complexity, large-array and render-batching performance, and WCAG 2.1 AA + keyboard navigation. Trigger when asked to review changes, check a diff against Handsontable conventions, assess architectural correctness, spot performance regressions, or verify accessibility — and as the design lens before or while implementing any core change.
Use when writing or modifying Jasmine/Puppeteer E2E tests (*.spec.js) for Handsontable, or when a bug fix or feature change needs E2E test coverage. Covers standard boilerplate, async/await rules, global helpers, event simulation, plugin lifecycle patterns, and writing theme-agnostic assertions that pass under all themes without branching on theme name.
