hunting-command-argument-and-flag-injection skillA

hunting-command-argument-and-flag-injection is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt argument and flag injection where untrusted input occupies a slot in a subprocess argument vector, with no shell involved, and the target program parses it as an option rather than data. Covers a value that starts with a dash and becomes a flag, and a value inserted before the program separates options from operands, turning a data argument into one that changes behavior: writing or reading a file, running an embedded command, changing a config or protocol, or reaching a network target. Thi.

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 unboundcompute/security-agent-skills/hunting-command-argument-and-flag-injection@git:20260903.6dac719

mdr add unboundcompute/security-agent-skills/hunting-command-argument-and-flag-injection@sha256:e530cdd21b7df083

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.
