2 things to look at

  • 25 days oldThe repository was created 25 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.
  • 1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

A synthetic fixture skill bundled with SkillGuard for SG10 (marketplace typosquatting detection) end-to-end tests. Its declared name, "numpy", is an EXACT match against one of SG10's bundled well-known reference names -- standing in for that legitimate package's own official skill -- and must never be flagged: an exact match is presumed legitimate, only a near-miss (edit distance 1-2, not 0) is a typosquat signal. Do not install or run this in a real agent.

Known-Name Legit Skill (fixture)

This skill's declared frontmatter name ("numpy") exactly matches a well-known package name in SG10's reference list. SG10 must stay quiet here: an exact match is the expected, legitimate case (e.g. the real "numpy" project publishing its own official skill), not a typosquatting attempt.

Run:

npx skillguard-cli scan ./examples/known-name-legit-skill

to confirm SkillGuard does NOT raise an SG10 finding for this fixture.
