Its `llms.txt` describes a framework for building AI-powered applications and agents with a modern TypeScript stack, and exposes agent-readable documentation links for agents, tools, skills, structured output, agent approval, supervisor agents, workflows, memory, evals, observability, and deployment. The linked docs also separate workflows, memory, and deployment into first-class areas instead of hiding them behind a single chat abstraction. For agent builders, the practical signal is to evaluate JavaScript and TypeScript frameworks by whether they provide inspectable application primitives: tool contracts, approval gates, workflow state, resumability, memory boundaries, telemetry, deployment targets, and documentation surfaces that other agents can read without scraping a marketing page.","sponsors":[]}
