building-api-authentication

Quick Review

The skill has good structural organization with external reference files and clear output specifications. However, the description and instructions are generic 'API building' content that doesn't match the specialized authentication focus (OAuth2, JWT, API keys, session management) advertised in the metadata. The instructions talk about general API development (resource models, endpoints, HTTP methods) rather than authentication-specific implementation steps. While task knowledge is partially present through referenced files, the core SKILL.md lacks authentication-specific guidance. The skill shows moderate novelty as authentication implementation can be complex, but the current content doesn't demonstrate specialized authentication knowledge that would justify the skill over a general-purpose agent. To improve: rewrite instructions to focus on authentication flows, token generation/validation, OAuth2 grant types, session management, and security best practices specific to authentication systems.
