Effect-TS library usage in TypeScript — Effect.gen generators, Schema.Struct/Schema.Class definitions, Layer/Context.Tag/Service patterns, Effect.pipe pipelines, Data.TaggedError/Data.Class error types, Ref/Queue/PubSub/Deferred concurrency primitives, Match module, Config providers, Scope/Exit/Cause/Runtime patterns, or any code using Effect's typed error channel (E parameter). Trigger when writing, reviewing, debugging, or refactoring TypeScript code that uses Effect — when you see imports from `effect`, `effect/*`, or any `@effect/*` scoped package (schema, platform, sql, opentelemetry, cli, cluster, rpc, vitest). Also trigger when the user asks about Effect patterns, migration from Promises/fp-ts/neverthrow to Effect, or how to structure an Effect application. Do NOT trigger for React's useEffect, Redux side effects, or general English usage of "effect" unless the context clearly involves the Effect-TS library.

The apartment-hunt CLI that actually works in 2026 — Surf-cleared bot protection plus a local SQLite store the website itself doesn't have. Trigger phrases: `find apartments in <city>`, `watch apartment listings for <area>`, `rank rentals by price per square foot`, `compare these apartments`, `use apartments-pp-cli`, `run apartments`.

DEPRECATED — prefer the official zentao-cli (https://github.com/easysoft/zentao-cli) and its skills (https://github.com/easysoft/zentao-skills) for new setups. This skill still works for existing @leeguoo/zentao-mcp users and remains useful for its bug resolution stats command. Use the zentao CLI to query and operate ZenTao bugs, tasks, stories, todos, products, programs, projects, executions, plans, releases, test cases, test tasks, test suites, docs, users, departments, issues, and risks. Use when the user mentions 禅道 or ZenTao, wants bug/task/story/todo/project/test/doc lookups or updates, wants bug resolution rate stats or reports (bug 解决率统计/解决数量统计/bug statistics/bug report) by product or person, or needs login / whoami / self-test for a 禅道 instance. ZENTAO_URL usually includes /zentao.

Designs iOS 18+ SwiftUI experiences with real taste — starting from user goals, not pixels. Use this skill whenever the user asks you to build SwiftUI views, screens, or experiences. Trigger when the user says "build a settings screen", "create a detail view", "design this properly", "I want this to feel like a native app", or any SwiftUI UI task. Also trigger when reviewing SwiftUI code for design quality, or when the user says the output "looks like a demo" or "feels generic." When building any user-facing SwiftUI view, lean toward triggering this skill.

Use when you need to address review or issue comments on an open GitHub Pull Request using the gh CLI.

Test React components with Testing Library patterns. Covers queries (getBy/findBy/queryBy), user-event interactions, async testing (findBy vs waitFor), accessibility testing, and MSW integration for API mocking. Use when: testing React components, simulating user interactions, testing forms, mocking API calls with MSW, or writing accessible tests. Keywords: testing-library, react testing library, getByRole, user-event, waitFor, MSW, screen.
