url-dump skillA

url-dump is agent-read markdown (skill) from huytieu/cog-second-brain: Quick capture URLs with automatic content extraction, insights, and categorization into knowledge booklets.

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 huytieu/cog-second-brain/url-dump@git:20260622.5e9851c
Exact content
mdr add huytieu/cog-second-brain/url-dump@sha256:de6f44da9b2bf0f4

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.
