echo skillA

echo is agent-read markdown (skill) from zhaojiannet/canon: Enforce Echo v5 handler conventions for Go, focused on error handling. Use when editing .go handler/route/middleware files or when the user mentions Echo, HandlerFunc, c.Bind, middleware, HTTPError, HTTPErrorHandler, error wrap, or graceful shutdown. Routes every failure through HTTPError and one central HTTPErrorHandler, matches errors with errors.Is/As, wraps and returns them, and starts the server with graceful shutdown..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add zhaojiannet/canon/echo@git:20260914.a9571da
Exact content
mdr add zhaojiannet/canon/echo@sha256:d0ebbf92860d2f03

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
