CLAUDE.md Rules Pack is a ready-made configuration file for Claude Code containing 40+ production-tested rules built from real software projects. Instead of writing your own CLAUDE.md from scratch—or watching Claude invent architecture decisions you never asked for—you copy in a curated ruleset that enforces your stack conventions, naming patterns, and review standards out of the box.
The rules address common Claude Code failure modes: straying from the established tech stack, ignoring project-specific patterns, generating code that passes a syntax check but fails a PR review. Each directive is concrete and actionable, not generic advice. The pack is designed to be edited—strip what doesn't apply, keep what does, and add your own on top.
Best suited for solo developers or small teams who use Claude Code regularly and want consistent output without babysitting every prompt. Works across any language or framework since the rules target behavior and process rather than syntax.
