Grades are a hygiene check, not a security guarantee.

Claude Code, Skill

Lamarck Skill

Lamarckian skill evolution - continuously monitors every real skill invocation, drives governed evolution of observed skills, and evolves itself by the same rules while running.

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit 38ad486eb786.

PERMISSION_DELETE_FILES

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    bin/install.js, line 117 fs.rmSync(dir, { recursive: true, force: true });

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
