skill-lineage

Lineage-aware skill evaluation — before installing or recommending any third-party agent skill, trace its family tree (forks, same-name rewrites, credited derivatives), drop pure mirrors, find the family member that actually fits, and screen derivative additions for stowaway instructions. Value for the user — install the version that fits THEM (a localization, a bug-fixing fork, a port for their toolchain) instead of blindly taking the most-starred origin, and catch injected instructions before they reach the agent. Trigger when the user asks "is there a better fork of this skill", "find derivatives", "which version is best", "is this a mirror", "check lineage", "找衍生版", "有没有更好的 fork", "哪个版本最好", "查族谱", or before installing a skill found via star-sorted search. NOT for diffing your own skill's git history (use plain git diff), NOT a security scanner (pair with dedicated tools for that).
