How does it handle authentication guidance?

The skill covers a wide range of methods including API Keys, OAuth 2.0 tokens, JWT, mTLS, and custom HMAC request signing for tamper-proof communication.

Does this skill provide code for specific frameworks?

Yes, it includes detailed implementation patterns for ASP.NET Core and Redis, though the core security principles and logic are applicable across all modern backend frameworks.

Does it support distributed rate limiting?

Yes, it provides logic and Lua scripts for implementing distributed rate limiting using Redis, specifically focusing on the Token Bucket strategy.

Can it help with OWASP compliance?

It provides direct mitigation strategies for the OWASP API Security Top 10 (2023), helping you address the most critical vulnerabilities like BOLA, SSRF, and Broken Authentication.

API Development

Secures web APIs through robust authentication, rate limiting, and protection against the OWASP API Top 10 vulnerabilities.

About

The API Security skill equips Claude with comprehensive knowledge and implementation patterns to harden web services against modern threats. It provides specific guidance on implementing secure authentication methods like OAuth 2.0 and HMAC signing, configuring distributed rate limiting using Redis, and establishing strict input validation and CORS policies. Whether you are designing a new microservice or auditing an existing gateway, this skill helps ensure your API layer is resilient against common attacks such as Broken Object Level Authorization (BOLA), SSRF, and resource exhaustion.
