Stop wasting tokens on bad schemas.

Most people call the LLM first. They parse the result. They find an error. Then they retry.

This costs money and time. You find out the schema is wrong after you pay for the call.

Do this instead:

• Validate your Pydantic model before you send the request.
• Use dummy data to test the model at boot.
• Test a known good example when you change the schema.

This finds bugs in CI or at boot. It does not happen during a paid call.

This method caught 60 percent of schema bugs. The other 40 percent are actual model failures. Those are the only ones you should retry.

Stop mixing schema errors with model errors. Save your tokens.
