sourcer skillA

sourcer is agent-read markdown (skill) from broomva/skills: Crawl a set of sites into a verified entity graph — companies, the people who run them, the relationships between them — where every claim points at the bytes it came from and nothing expands until it verifies. Agents read pages that are already on disk and return byte spans; a fetch daemon is the only thing that may put bytes there, so fabricating evidence is not a callable path rather than something a check must catch. Twelve gates run over what the run left on disk, eleven of them fail closed.

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 broomva/skills/sourcer@git:20260825.f21d7c9
Exact content
mdr add broomva/skills/sourcer@sha256:99f9507ddd8fa099

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.
