error-handler-middleware

Quick Review

The skill is well-structured and clearly positioned within backend development, but lacks substantive implementation details. The description explains when it triggers but not what it actually does or how. There is virtually no task knowledge provided—no specific patterns, code examples, error handling strategies, or framework-specific guidance for Node.js, Python, or Go. While the structure is clean, the content is mostly boilerplate that doesn't equip a CLI agent to actually implement error handler middleware. The novelty is moderate since error handling patterns can be complex, but without concrete guidance, the skill doesn't meaningfully reduce token costs or provide value beyond what a general-purpose agent could produce.
