IHttpClientFactory and typed HTTP clients for .NET 10 applications. Covers named/typed/keyed clients, DelegatingHandlers, resilience with Microsoft.Extensions.Http.Resilience, and testing patterns. Load this skill when configuring HTTP clients, adding retry/circuit breaker policies, or when the user mentions "HttpClient", "IHttpClientFactory", "AddHttpClient", "typed client", "named client", "DelegatingHandler", "resilience", "retry", "circuit breaker", "hedging", "Polly", "AddStandardResilienceHandler", "socket exhaustion", or "Refit".
Build Cypress test suites in TypeScript: E2E tests, component tests, custom commands, cy.intercept network control, cy.session login, Cypress Cloud, and CI integration. Covers retry-ability, the command queue, cross-origin flows with cy.origin, and data-driven testing with fixtures. Use when: "write E2E test in Cypress," "Cypress page object / custom command," "cy.," "cy.intercept," "Cypress component test," "Cypress Cloud," "cypress.config.ts." Not for: Playwright suites — use playwright-automation; flaky-test healing or quarantine — use test-reliability; bulk selector regeneration after a UI refactor — use selector-drift-recovery; Selenium-to-Cypress conversion — use test-migration. Related: playwright-automation, ci-cd-integration, visual-testing, unit-testing, test-reliability.
Modernize test suites to use modern Swift Testing features or migrate from XCTest.
EMC pre-compliance risk analysis for KiCad PCB designs — 18 check categories, 44 rule IDs covering ground planes, decoupling, I/O filtering, switching harmonics, clock routing, differential pair skew, board edge radiation, PDN impedance, return paths, crosstalk, ESD protection, shielding, and magnetic leakage from switching inductors. Produces severity-ranked risk report with pre-compliance test plan. Supports FCC Part 15, CISPR 32, CISPR 25 (automotive), MIL-STD-461G. SPICE-enhanced when available. Use when the user asks about EMC, EMI, radiated/conducted emissions, FCC compliance, CE marking, CISPR, ground plane issues, decoupling strategy, clock routing EMC, switching noise, differential pair skew, or whether their board will pass EMC testing. Also for "will this pass FCC?", "check my EMC", "is my ground plane okay?", "check my decoupling", or "generate an EMC test plan".
Write Patrol end-to-end (E2E) tests for a Flutter app — order of actions, Patrol API and assertion rules, native dialog handling, and test-key conventions. Use when adding or editing Patrol/integration tests, assigning widget keys for testing, or debugging a failing Patrol test.
You are an expert in Nest.js with deep knowledge of enterprise-grade Node.js application architecture, dependency injection patterns, decorators, middleware, guards, interceptors, pipes, testing strategies, database integration, and authentication systems.
Bring up I2C sensors on a XIAO ESP32S3 and stream their values to serial: BH1750 ambient light, BME280 temperature/pressure/humidity, and BNO055 9-DOF fused orientation, individually as unit tests or all three together on one bus. Use this skill WHENEVER the task involves I2C sensors on an ESP32S3 — wiring one up, "센서 값 읽어줘", a sensor that answers the scan but reads zeros, unit-testing a module before trusting it, deciding whether a 0x76 part is a BME280 or a BMP280, or a BNO055 whose orientation stays at 0. It carries hardware-verified sketches and the address/clock traps that make a healthy-looking sensor return nothing.
Guides agents through integrating transactional email sending via Mailtrap's Email API, including sandbox testing, domain verification, and API authentication. Use when implementing email-sending features, debugging delivery issues, or setting up safe dev/staging email testing.
Review EXISTING test code for quality, smells, and testability issues. Detects test smells across six dimensions — readability, reliability, diagnostic value, design, AI-generated, and coverage — analyzes testability of application code, and backs the qualitative smells with mutation testing. Use when: "review my tests," "test quality audit," "test smells," "testability analysis," "are these tests any good." Not for: generating new tests — use `ai-test-generation`. Not for: testing AI features in your product — use `ai-system-testing`. Related: unit-testing, shift-left-testing, coverage-analysis, ai-test-generation.
Build and run a full email marketing channel — list building, deliverability, segmentation, newsletter strategy, campaign types, A/B testing, and email design. Use when the user says "email marketing", "email strategy", "email list", "newsletter", "email campaigns", "email list building", "email deliverability", "email open rates", "email segmentation", "email design", "email calendar", "grow my email list", "email marketing plan", "broadcast emails", "email engagement", or wants to use email as a primary owned marketing channel beyond just automated flows.
Build or repair game inventory, loot, equipment, tooltips, drag-and-drop, persistence, and progression systems. Use for item schemas, pickup flows, stack rules, equipment slots, atomic swaps, save migration, and no-loss regression testing.
Identify motif-level structures in a piece of information, expand abstract relationships back into concrete observable phenomena, and then use wind tunnel testing to verify key causal relationships and boundaries. USE WHEN user says 'find structure', 'what is the motif', 'structure wind tunnel', 'underlying structure', 'don’t just do AB testing', or wants to explore the generative mechanism behind a problem. Only expand cross-domain sources or multi-motif combinations when explicitly requested by the user. NOT FOR general summaries, single analogies, factual queries, or execution tasks with a clear unique solution.
