csrf-protection skillA

csrf-protection is agent-read markdown (skill) from secondsky/claude-skills: Implements CSRF protection using synchronizer tokens, double-submit cookies, and SameSite attributes. Use when securing web forms, protecting state-changing endpoints, or implementing defense-in-depth authentication..

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 secondsky/claude-skills/csrf-protection@git:20260719.059fc9f
Exact content
mdr add secondsky/claude-skills/csrf-protection@sha256:24c0c47f86be9781

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.
