nextjs-cache-poisoning skillA

nextjs-cache-poisoning is agent-read markdown (skill) from dreadnode/capabilities: Internal cache poisoning in Next.js via stale cache entries and header manipulation. Use when target runs Next.js (/_next/ paths, x-nextjs-cache header, __nextjs_original-cache-control) and you need to poison cached responses..

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 dreadnode/capabilities/nextjs-cache-poisoning@sha256:287ff884ddfc357f

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.
