How does usage-based diffing help reduce noise?

By providing your application's operations (queries and mutations), the skill can determine if a breaking change actually affects your clients, allowing you to safely remove unused fields without alerts.

What does the GraphQL Inspector Diff skill do?

It leverages the GraphQL Inspector CLI to compare two GraphQL schemas, identifying breaking, dangerous, and non-breaking changes to help developers prevent API regressions.

Can I compare a local schema with a live production endpoint?

Yes, the skill supports comparing local schema files against remote URLs or comparing two different remote endpoints directly.

Does this skill support Apollo Federation?

Yes, it includes specialized commands for comparing federated schemas and validating subgraphs.

Can this be integrated into my existing CI/CD workflow?

Absolutely. The skill provides standardized configurations for GitHub Actions and GitLab CI to automate schema checks on every pull request.

Identifies breaking changes and validates GraphQL schema migrations across branches, files, and live endpoints.

About

The GraphQL Inspector Diff skill equips Claude with expert knowledge for managing API evolution and preventing regressions. It utilizes the GraphQL Inspector CLI to compare schema versions, categorizing changes as breaking, dangerous, or non-breaking. Whether comparing local files, Git references, or live remote endpoints, this skill helps developers automate schema validation, implement usage-based diffing to reduce noise, and maintain high API standards through standardized CI/CD patterns and best practices.
