The Type Definition Consistency Checker is a deterministic auditing tool designed to prevent structural drift in full-stack applications. By using AST-based parsing, it identifies discrepancies between frontend and backend schemas, such as missing fields, type mism/matches (e.g., string vs number), and optionality misalignments. Use inspect_structure to view parsed metadata, sync_definitions to perform a full-suite audit across multiple definitions, or compare_definitions for targeted reviews of specific changes.

See how to talk to your AI agent using Type Definition Consistency Checker.

Check if these two Zod schemas and TypeScript interfaces are in sync.

The `sync_definitions` audit is complete. No inconsistencies were detected; all fields, types, and optionality markers match perfectly.

What are the fields in this Pydantic model?

The parsed structure contains the following fields: `user_id` (String-type, required), `email` (String-type, required), and `is_active` (Boolean-type, optional).

Compare this new interface with the existing one.

The `compare_definitions` tool identified one change: Field `last_login` was Added to the target definition.

The tool supports `typescript_interface`, `zod_schema`, and `pydantic_model` formats.
