Hono Validation
If you're building APIs with Hono and need request validation, this handles the middleware layer with type safety baked in. It covers the built-in validator plus integration patterns for Zod, TypeBox, and Valibot through Standard Schema support. You get validation across JSON bodies, forms, query params, headers, cookies, and path params with proper type inference flowing into your handlers. The skill has passed audits from Gen Agent Trust Hub, Socket, and Snyk, and it's sitting at 206 installs with decent GitHub activity. Most useful when you're past the hello world stage and need to lock down your request surface area without writing boilerplate validation code.
