SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the challenge of efficiently representing structured data for Large Language Models (LLMs), reducing token usage while maintaining data integrity.

Core Features & Use Cases

  • TOON Format: Utilizes Token-Oriented Object Notation for compact, LLM-friendly data serialization.
  • Syntax Rules: Provides clear guidelines for arrays, objects, and quoting conventions.
  • org-patterns.toon: Defines a specific format for capturing and sharing organizational learnings.
  • Use Case: Convert complex JSON data into TOON format to significantly reduce the token count in LLM prompts, enabling more data to be processed within context limits.

Quick Start

Use the toon-format skill to convert the provided JSON data into TOON format.

FAQPage Schema
How do I reduce token usage when passing JSON data to an LLM?

To reduce token usage, convert JSON data into Token-Oriented Object Notation (TOON) format. TOON provides a compact, LLM-friendly data serialization method that maintains data integrity while significantly lowering token counts in prompts.

What is the best way to serialize structured data for large language models?

The best way to serialize structured data for large language models is using TOON format. It optimizes data representation for LLM token efficiency, allowing you to process more information within context limits compared to standard JSON.

How does TOON format syntax handle arrays and objects?

TOON format syntax provides specific, clear guidelines for structuring arrays, objects, and quoting conventions. These rules ensure compact data representation while preserving the structural integrity needed for accurate LLM parsing.

Can I convert existing JSON files to TOON format automatically?

Yes, you can convert existing JSON files to TOON format automatically. The conversion process adheres to specific TOON syntax rules, transforming complex JSON into a compact structure that minimizes LLM token consumption.

When do I need to use a TOON file for knowledge sharing?

You need to use a TOON file for knowledge sharing when capturing and distributing organizational learnings. Creating an `org-patterns.toon` file defines a specific, token-efficient format for sharing this structured knowledge with LLMs.

Are there limitations to using TOON format for LLM data serialization?

TOON format is optimized specifically for LLM token efficiency and requires adherence to its syntax rules for arrays, objects, and quoting. It is specialized for compact data representation rather than general-purpose data serialization.
