How to check schema version compatibility with your AI

Connect the JSON Schema Validator once. After that, your AI handles the heavy lifting of comparing versions and spotting structural mismatches.

Short answer

How can I check if a new schema version will break my data?

Your AI uses the validator to run a comparison between your current schema and the proposed update. It identifies missing fields, type mismatches, or structural shifts that would invalidate your existing data. You get a clear report of what changed and what will break.

The results of your check.

Where every issue lands.

The AI processes the schema files and delivers these specific outcomes.

VALIDATION

Breaking change alerts

The AI flags any field deletions or type changes that conflict with your current data. You see exactly which keys are no longer compatible.

ANALYSIS

Structural diffs

The tool compares the two versions to show how the hierarchy has shifted. You get a breakdown of added, removed, or modified properties.

REPORTS

Compatibility logs

The AI generates a summary of the validation results. This gives you a clean record of whether the new version is safe to deploy.

HUMAN

Manual fixes

The AI identifies the errors, but you decide how to resolve them. You must manually adjust your data or the schema to fix the mismatches it finds.

The workflow

What your AI does when the schema arrives.

The AI acts as a gatekeeper between your old data and your new definitions.

  1. Ingest schemas

    Your AI pulls the current and proposed JSON schema files into its context. It prepares both versions for a side-by-side comparison.

  2. Run comparison

    The AI executes the compatibility check to find discrepancies. It looks for changes in required fields and data types.

    evaluate_schema_compatibility

  3. Identify conflicts

    The AI isolates specific points where the new schema violates the old structure. It maps these conflicts to specific paths in your JSON.

  4. Summarize results

    The AI presents a final verdict on whether the update is backward compatible. It highlights the specific risks you need to address.

FAQ

How the validator behaves

  • 01

    Can the AI automatically fix my schema to make it compatible?

    No. The AI identifies the conflicts, but you must manually edit the schema or the data to resolve them.

  • 02

    Will the AI change my actual data files?

    No. The AI only reads the schema files to perform the comparison. It does not have permission to write to or modify your data.

  • 03

    Does it work with any JSON schema version?

    Yes, as long as the schema follows standard JSON schema specifications, the AI can evaluate it.

  • 04

    Can the AI check compatibility between two different repositories?

    Yes, if you provide the paths or access to both repositories, the AI can compare them.

  • 05

    Does it check for data validation or just schema structure?

    It checks the structure of the schema itself to ensure the new definition doesn't break the rules established by the old one.
