toon-format/toon — 🎒 Token-Oriented Object Notation (TOON) – Compact, human-readable, schema-aware JSON for LLM prompt…

Description and use

Toon (Token‑Oriented Object Notation) is an open‑source, schema‑aware serialization format that packs JSON‑style data into a compact, human‑readable representation optimized for large‑language‑model prompts. The repository provides the full specification, benchmark results comparing TOON to plain JSON and other formats, and a TypeScript SDK for parsing, validating, and generating TOON data. It targets AI/ML developers who need efficient, token‑light data interchange for prompt engineering and model‑side processing.

Problem

toon-format/toon helps add AI capability without starting from a blank model stack.

Outcome

Medium: useful for prototypes or internal workflows, with dependency and maintenance checks before production.

Workflow

• prototype AI features
• build RAG or agent workflows
• evaluate model tooling
