Can this skill handle very large JSON files?

Yes, it utilizes streaming processing via libraries like ijson to handle massive datasets in chunks, preventing memory overflow while maintaining high processing speeds.

What is TOON encoding and how does it help?

TOON (Token-Optimized Object Notation) is a custom format that uses specialized type markers to reduce data size by 40-60% compared to standard JSON, specifically designed to save token costs in LLM interactions.

Is the JSON optimization significantly faster than native Python?

Yes, by leveraging orjson and C-based loaders, the skill typically achieves serialization and deserialization speeds 2x to 5x faster than the standard Python json module.

Which validation libraries are supported?

The skill integrates with industry standards including Pydantic, JSON Schema, Cerberus, and Marshmallow for comprehensive type-safe data validation.
