TONL (Token-Optimized Notation Language)
Combines compact binary-efficient serialization with JSONPath-style querying, aggregation, and fuzzy/temporal search capabilities—all targeting LLM token reduction (up to 60% smaller than JSON). Built as a zero-dependency TypeScript library with 698 passing tests, it offers both a document API for data manipulation and CLI tools for encoding, validation, and interactive analysis across Node.js and browsers (10.5 KB gzipped).
