CI/CD pipeline advisor for GitHub Actions workflows, deployment scripts, and server task scheduling.
Use when: (1) editing or reviewing .github/workflows/*.yml files, (2) working on deployment scripts
in bin/, (3) questions about cron jobs or systemd services on local servers, (4) Docker image
build/push pipelines, (5) security hardening for CI/CD (secrets, permissions, attestations).
This skill provides advice and reviews - it does not execute server commands.
