From 497c5ea72733d6b635e48484e7ef23da50794d02 Mon Sep 17 00:00:00 2001 From: Gerald Fruhmann Date: Sat, 13 Jun 2026 21:39:43 +0200 Subject: [PATCH] feat: add review-public skill Pre-publication repository scan covering 5 domains: secrets in git history, PII in test data, governance files (LICENSE/SECURITY.md), branch protection settings, and CI/CD hardening. Produces a severity-rated findings report with copy-pasteable remediation steps.
