etag-handler

Quick Review

The skill is well-structured but severely lacking in actual content. The description is too generic and doesn't explain what ETag handling entails (HTTP caching, conditional requests, validation). There are no concrete steps, code examples, or implementation guidance for ETag patterns like If-None-Match, If-Match, generating ETags, or handling 304 responses. A CLI agent would not know how to actually implement ETag functionality based solely on this description. The novelty is low since ETag implementation is straightforward for most developers and well-documented in HTTP specs. The skill needs substantial technical content about ETag generation strategies, middleware patterns, cache validation flows, and concrete code examples to be useful.
