Build browser-based web applications with spheres — a TypeScript framework with fine-grained reactive views and token-based state management. TRIGGER when code imports `spheres`, `spheres/store`, `spheres/view`, or `spheres/server`; when a user asks to build, modify, or debug a spheres application; or when discussing `HTMLBuilder`/`SVGBuilder`, `container`/`derived`/`supplied`, `renderToDOM`, `createStore`, `useEffect`, `useCommand`, `useContainerHooks`, `createStringRenderer`, `createStreamRenderer`, or `activateZone`.

Write tests using best-behavior — a TypeScript testing framework that produces executable documentation. Tests are structured as behaviors, examples, and scripts with facts/steps/effects. TRIGGER when code imports `best-behavior`, `best-behavior/browser`, `best-behavior/run`, `best-behavior/server`, `best-behavior/coverage`, `best-behavior/page`, or `best-behavior/transpiler`; when a user asks to write, modify, review, or debug tests in a project using best-behavior; or when discussing `behavior`, `example`, `fact`, `step`, `effect`, `Context`, `contextMap`, `browserContext`, `globalContext`, `behaviorContext`, `procedure`, `outcome`, `situation`, or the `best` CLI.

Write assertions using great-expectations — a TypeScript matcher library that builds rich, human-readable descriptions of values. Assertions are composed from a MatchEvaluator (`is`, `throws`, `resolvesTo`, `rejectsWith`, `eventually`) and a `Matcher<T>`. TRIGGER when code imports `great-expectations`; when a user asks to write, modify, review, or debug assertions in a project using great-expectations; or when discussing `expect`, `is`, `equalTo`, `stringContaining`, `arrayWith`, `objectWith`, `valueWhere`, `Matcher`, `MatchResult`, `Valid`, `Invalid`, or custom matcher design.
