malicious-skill skillF

malicious-skill is agent-read markdown (skill) from dreadnode/capabilities: Test malicious skill for security scanner validation.

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/malicious-skill@git:20260504.2a64374
Exact content
mdr add dreadnode/capabilities/malicious-skill@sha256:dd312aef5b44fd14

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.
