json-repair

What problem does it solve?

This Skill automatically repairs invalid or malformed JSON strings, which are commonly produced by Large Language Models (LLMs), making them parsable and usable in your applications.

Core Features & Use Cases

• Robust JSON Parsing: Handles missing quotes, trailing commas, unescaped characters, and incomplete structures.
• LLM Output Handling: Acts as a drop-in replacement for json.loads() that auto-repairs unreliable model outputs.
• Schema-Guided Repair: Can optionally use JSON Schema or Pydantic models to guide repairs, fill missing values, and coerce types.

Quick Start

Use the json-repair skill to fix the following broken JSON string: '{"name": "test", "value": 42,}'
