React patterns for hooks, effects, refs, and component design with escape hatch guidance. \n \n Effects synchronize with external systems only (WebSocket, third-party libraries, browser APIs); most component logic should avoid Effects entirely \n Common anti-patterns: derived state, expensive calculations, prop-change resets, and event handling all belong outside Effects—use render calculations, useMemo, key props, and event handlers instead \n Effect dependencies must never be suppressed; use u

When running Playwright tests from Claude Code or any CLI agent, always use minimal reporters to prevent verbose output from consuming the context window.

Type-first Python development using dataclasses, discriminated unions, NewType, and Protocol to make illegal states unrepresentable. \n \n Define data models and function signatures before implementation; use frozen dataclasses, Literal-based discriminated unions, and NewType for domain primitives to prevent invalid states at type-check time \n Leverage Protocol for structural typing, TypedDict for external data shapes, and exhaustive pattern matching with match statements to catch incomplete lo

Fetch web content as clean markdown using markdown-native endpoints, selector-based HTML extraction, or bundled fallback parsing. \n \n Prioritizes markdown-native responses (content-type: text/markdown) before falling back to HTML extraction \n Includes pre-configured selectors for common documentation sites (Anthropic, MDN, GitHub) and a generic fallback for article/main content regions \n Provides html2markdown with CSS selector support for fine-grained content isolation, excluding navigation

TypeScript patterns for type-first development, making illegal states unrepresentable, and exhaustive handling. \n \n Use discriminated unions, branded types, and const assertions to encode business rules in the type system and prevent invalid states at compile time \n Validate at system boundaries with Zod schemas as single source of truth; infer TypeScript types automatically to keep types and validation in sync \n Enforce exhaustive handling with never checks in switch statements and default
