What kinds of JSON errors can this skill fix?

It automatically handles missing quotes around keys/values, trailing commas, unescaped special characters, single quotes used instead of double quotes, and mismatched brackets or braces.

Is this skill useful for streaming AI responses?

Absolutely. It includes a stream_stable mode specifically designed to handle and repair partial JSON strings during incremental streaming output.

Does this require any external API calls?

No, the json-repair skill runs entirely locally using a zero-dependency Python module, ensuring your data remains private and repairs are performed instantly.

Can I use this as a replacement for the standard json.loads()?

Yes, it provides a json_repair.loads() function that acts as a drop-in replacement, validating the JSON first and repairing it only if the standard parser fails.

Does it support schema validation?

Yes, it supports schema-guided repairs using Pydantic v2 models or JSON Schema, which allows it to fill in missing required fields and coerce data types during the repair process.

Automatically fixes malformed or incomplete JSON strings generated by AI models to ensure reliable data parsing.

The json-repair skill provides a robust solution for handling the inconsistent or malformed JSON structures often produced by Large Language Models. By integrating a specialized Python library, it automatically corrects common defects such as missing quotes, trailing commas, unescaped characters, and mismatched brackets. This skill is essential for developers building automated pipelines where LLM outputs must be consumed by structured systems, offering both a drop-in replacement for standard JSON parsing and advanced schema-guided validation to ensure data integrity without manual intervention.
