etag-handler

Quick Review

The skill has clear structure and addresses a moderately useful API development concern (ETags), but severely lacks implementation details. The description is too generic, merely restating 'etag handler' without explaining what ETags are, how they work for caching/conditional requests, or what specific operations are supported. Task knowledge is minimal - no code examples, no concrete steps for implementing ETag generation, validation, or conditional request handling. While ETag implementation has some complexity (hashing strategies, 304 responses, If-None-Match headers) that could justify a skill, this implementation provides almost no actual guidance beyond boilerplate text. To improve: add concrete examples of ETag generation algorithms, middleware implementation, conditional GET/PUT handling, and HTTP header processing.
