breadcrumb

Add Breadcrumb LLM tracing to any Node.js/TypeScript project. Use this skill whenever the user wants to add observability, tracing, or monitoring to their LLM application — especially if they mention Breadcrumb, trace LLM calls, track token costs, monitor AI agents, or instrument their Vercel AI SDK usage. Also use when the user says "add tracing", "track my LLM costs", "I want to see what my agent is doing", or asks about observability for AI applications.
