Is analyzing-cyber-kill-chain safe to install?

No critical findings, some security notes. The scan covers prompt injection, hidden Unicode, remote code execution and credential access in every text file of the skill. It cannot judge intent, so read any flagged line in context before installing.

How was this score calculated?

Four checks of 25 points each: spec, efficiency, clarity and security. Findings take points off the check they belong to, and any critical finding caps the grade at F. The same scanner runs in your browser at proskills.dev/scan.

It was made from commit 54a7988 on 2026-10-16. If the skill has changed since, paste the new version into the scanner for a fresh score.
