How does this skill help in securing APIs?

The skill provides automated tools to find the exact depth at which an API becomes unresponsive, allowing developers to set informed safety limits using libraries like graphql-depth-limit.

What is a GraphQL depth limit attack?

It is a type of Denial-of-Service attack where a client sends a deeply nested query that exploits circular relationships in a schema, forcing the server to exhaust CPU and memory resources.

Can I use this for automated CI/CD security testing?

The included Python script can be integrated into security pipelines to verify that GraphQL depth limits are properly enforced across different environments.

Does this support testing for alias amplification?

Yes, it includes techniques to test alias-based amplification, where a single query uses multiple aliases to bypass traditional per-query complexity checks.

Tests GraphQL APIs for resource exhaustion vulnerabilities by executing and analyzing deeply nested recursive queries.

This skill enables Claude to identify and simulate GraphQL depth limit attacks, a critical Denial-of-Service (DoS) vector targeting GraphQL endpoints. It provides comprehensive methodologies for testing how servers handle recursive relationships, alias-based amplification, and complex fragment spreads. Designed for security researchers and developers, the skill includes automated Python scripts for progressive testing and actionable mitigation strategies to secure APIs against resource exhaustion and performance degradation.
