AI-Powered API Contract Reviewer for Type-Safety Checks

AI-Powered API Contract Reviewer for Type-Safety Checks

This AI agent skill provides an automated review of API contract changes for type-safety and backward compatibility issues. It focuses on identifying potential disruptions in API signatures, schema drift, serialization problems, and type-boundary leaks within modified code.

What this skill does

• Analyses changes to public API signatures, routes, or response shapes to detect breaking changes that may affect existing consumers without proper versioning.
• Flags deviations in request and response shapes from their documented or generated schema, and notes undocumented required fields.
• Identifies serialization issues, such as values that may not correctly transmit across network boundaries, including date formatting and number precision loss.
• Detects use of imprecise or weakening type assertions, like `any` or `unknown`, at type boundaries.
• Evaluates enum or union modifications for compatibility, including additions, removals, and changes to field names, nullability, or defaults.

Who it is for

This skill is intended for software developers and development teams who use AI coding agents like Claude Code, Cursor, or Codex to manage API interfaces. It assists those responsible for ensuring consistent and reliable API interactions across service architectures.

Use cases

• Verifying API changes between microservices to prevent disruption of dependent services in a distributed system.
• Auditing changes in API contracts when integrating new features or modules in an application.
• Performing targeted reviews of code diffs that alter API interactions as part of a continuous integration/continuous deployment (CI/CD) pipeline.

Technical details

This skill employs agent-skills, aiapplication, and api-contract capabilities to perform its evaluations. The analysis is scope-limited to code differences (diffs) and applies insights within the context of impacted API consumers, such as front-end components or interconnected services.
