traefik-hardening skillA

traefik-hardening is agent-read markdown (skill) from air-gapped/skills: Harden a Traefik 2.x/3.x reverse proxy against abusive or unwanted traffic — per-identity rate + concurrency limiting, IP allowlisting, request-body buffering, middleware chaining, keying limits on a JWT claim/header instead of raw source IP, air-gapped plugin loading (localPlugins/WASM), and detection/response via access logs. Covers the 2.x→3.x middleware deltas (IPWhiteList→IPAllowList, Redis-backed distributed RateLimit, status-based Retry), the single-leader-counting trap, and where Traefik.

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.
