Understand and reduce token usage with ContextSpy context profiler

ContextSpy is a developer tool that profiles LLM context windows to visualize and quantify token usage per component, helping engineers identify inefficiencies and reduce costs. It targets developers building AI applications who need to optimize prompt budgets and debug context overflow. The project is interesting because it brings much-needed observability to the opaque token economy of LLM interactions, enabling data-driven cost reduction.
