Devops Skills

Diagnose and validate cron expressions before they ship. Catches the five silent death-traps: impossible dates that never fire, OR-semantics that fire too often, midnight spikes, uneven step drift, and leap-year February 29.

Detect environment variable drift across .env files before deploy. Use when a user has multiple .env files (.env, .env.local, .env.staging, .env.production), when debugging "works on my machine" config issues, or when setting up a new environment. Scans 12 languages (Node, Python, Ruby, Go, Rust, Java, PHP, Docker, shell, YAML, TOML, JS/TS) to find where env vars are actually used and flags missing/extra/changed values across environments.

Audit Dockerfiles for layer bloat, cache-busting patterns, security smells, and best-practice violations. Use when a user writes or reviews a Dockerfile, when a Docker image is too large, when builds are slow, or when hardening a container for production.
