extracting-nday-from-a-patch skillA

extracting-nday-from-a-patch is agent-read markdown (skill) from unboundcompute/security-agent-skills: Turn a security patch or version diff into fresh findings: infer the fixed vulnerability from what the fix changed, reconstruct the pre-patch bug, then hunt the paths the fix did not cover and the same bug in code it never touched. Use when you have a fix commit, a vague advisory with a linked diff, a version bump, or a "security release" and want to know what it silently fixed and what it missed. Covers reading a fix as a treasure map, incomplete-fix analysis, and variant discovery in the same .

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/extracting-nday-from-a-patch@git:20260816.c75b58d
Exact content
mdr add unboundcompute/security-agent-skills/extracting-nday-from-a-patch@sha256:ffc00edbdf4cdb22

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.
