Conventions for observing a multi-step AI SDK agent in a Next.js app — how to model every agent boundary as a closed TypeScript discriminated union, emit it from a single recorder that isolates volatile experimental callback names, stream it as custom data-trace-event parts over the same UI message stream, reduce it in a store, and derive the view through pure selectors with cost computed in one pricing module. Use whenever creating, updating, or porting the src/lib/trace module — trace event union, recorder, pricing, run store, selectors, or the agent run route. Triggers include: 'observe the agent', 'trace events', 'agent timeline', 'token usage', 'tool call timeline', 'stream agent steps', 'cost per run', 'add a trace event', 'instrument the agent'.
EnglishConventions for the multi-provider model layer in Next.js + AI SDK apps — how to structure the registry, customProvider aliases, available-providers detection, and model resolution so the rest of the app never touches raw model strings or provider packages. Use whenever creating, updating, or porting the src/lib/ai/ module — registry, customProvider aliases, available-providers detection, model resolution. Triggers include: 'set up models', 'add a provider', 'multi-provider', 'model registry', 'model picker', 'switch model'.
