Shell

This is a comprehensive shell scripting reference with 49 rules organized by priority, from critical safety issues like command injection prevention down to style preferences. It's built for AI agents but reads like a well-structured style guide. You'd pull this in when writing bash scripts, reviewing Dockerfiles, or debugging CI pipelines. The rules are properly categorized (safety, portability, error handling) and each links to detailed examples with before/after code. Honestly, the strict prioritization is the standout bit here. It separates "your script will have security holes" from "your indentation is inconsistent," which matters when you're trying to ship fast. Based on solid sources like ShellCheck and the Google style guide.
