rosuh Bundle

Instructions to make or update an app's UI so that it adapts to different Android devices including phones, tablets, foldables, laptops, desktop, TV, Auto and XR. It includes how to handle different window sizes, pointing devices (such as mouse) and text entry devices (such as keyboard) using the Compose MediaQuery API. It also covers multi-pane layouts using Navigation3 Scenes, adaptive UI components (such as buttons) with varying target sizes, and adaptive layouts (including navigation areas - nav rails and nav bars) using the Compose Grid and FlexBox APIs.

rosuh Bundle

Learn how to install and migrate to Jetpack Navigation 3, and how to implement features and patterns such as deep links, multiple backstacks, scenes (dialogs, bottom sheets, list-detail, two-pane, supporting pane), conditional navigation (such as logged-in navigation versus anonymous), returning results from flows, integration with Hilt, ViewModel, Kotlin, and view interoperability.

rosuh Bundle

Provides a complete workflow for implementing verified email retrieval on Android Credential Manager API. Use this skill to integrate a secure, OTP-less email verification flow into an Android app. This skill solves the problem of high-friction sign-up processes by leveraging cryptographically verified credentials from trusted providers like Google.

pramoddutta Skill

Design API-level test coverage from an endpoint or contract. Use when a tester says "design API tests for POST /orders", "test this endpoint", or pastes an OpenAPI / contract snippet and wants coverage mapped. Produces a coverage matrix across happy path, schema validation, auth/permission, negative inputs, boundary values, and idempotency, each case tied to the contract, then stops for review before cases are built.

pramoddutta Skill

Designs and generates API tests using Playwright's request context. Use when an SDET says "write API tests for this endpoint", "test the /orders API", "add schema validation for this response", "cover the negative cases", or pastes an OpenAPI/endpoint spec. Produces happy-path, schema-validation, auth, and negative/boundary tests — a draft the engineer runs against a real service.

pramoddutta Skill

Designs Playwright route interception and mocking. Use when an SDET says "mock this API", "stub the /orders response", "force a 500 error state", "make this test deterministic without the backend", or "intercept network calls". Produces page.route / fulfill handlers to stub responses, simulate errors, and remove backend flakiness — a draft the engineer wires in and runs.

axross Bundle

Working on Jest itself — the runner layer rather than the tests' content, covering its config, API, CLI, and transform and isolation mechanics. Triggers on a Jest config, `jest.fn`, `jest.spyOn`, `jest.mock`, `unstable_mockModule`, `useFakeTimers`, `toMatchSnapshot`, `moduleNameMapper`, `transformIgnorePatterns`, `next/jest`, `jest-expo`, a `--runInBand` or `--detectOpenHandles` run, or `Cannot use import statement outside a module`. For what is worth testing and the unit-versus-e2e call, use a unit-testing capability; for browser or device suites, an end-to-end-testing one. Baseline Jest 30.4.2.

axross Bundle

Working on Vitest itself — the 4.x runner layer rather than the tests' content, covering config, the `vi` API, pools, coverage, and Browser Mode, plus driving it without hanging a session. Triggers on `vitest.config`, `vi.mock`, `vi.useFakeTimers`, `expect.poll`, `toMatchInlineSnapshot`, `test.extend`, `projects`, `pool`, `browser.instances`, `toMatchScreenshot`, `*.test-d.ts`, `import.meta.vitest`, or a config key Vitest 4 silently ignores. For what to assert and how a spec is shaped, use a unit-testing capability; for journeys and server lifecycle, an end-to-end one. Lookup-first where the option surface moved from v3.
