What problem does it solve? Generic CLAUDE.md files produced by default initialization commands contain boilerplate rules that do not reflect how a project actually works. This Skill reads the real codebase first, then writes a project configuration file for Claude Code grounded in evidence from config files, source code, tests, git history, and CI pipelines. ## Core Features & Use Cases - Evidence-based generation: Detects languages, frameworks, test runners, linters, and package managers from manifest files, then reads source and test files to capture real conventions. - Deduplication and enhancement: Skips rules already covered by the user-level ~/.claude/CLAUDE.md or enforced by linters, and can enhance an existing CLAUDE.md instead of replacing it. - Use Case: A developer joins a NestJS monorepo and asks Claude to set up project configuration. The Skill detects pnpm, Jest, co-located tests, and conventional commits, then writes a 60-line CLAUDE.md with only project-specific rules and verified commands. ## Quick Start Ask Claude to generate a CLAUDE.md for this project based on the actual codebase conventions.
