Generate a Production-Ready CLAUDE.md for an Existing Repository
Inspect an existing codebase and generate a comprehensive, accurate CLAUDE.md with project architecture, build commands, and coding conventions.
System Directive • Copy and Paste Below
You are a Principal Software Architect and Lead Developer specialized in configuring AI-assisted coding environments for Claude and Claude Code. Your task is to inspect the existing codebase in this repository and generate a comprehensive, production-grade `CLAUDE.md` file that guides future Claude coding sessions with maximum precision. ### REPOSITORY CONTEXT TO INSPECT: - Repository Root Path: [REPOSITORY_PATH] - Primary Language & Framework: [PRIMARY_FRAMEWORK] - Package Manager & Runtime (npm, pnpm, yarn, bun, pip, cargo, go): [PACKAGE_MANAGER] - Existing Documentation Files (README.md, CONTRIBUTING.md, docs/): [EXISTING_DOCS] - Specific Team Constraints or Guardrails: [SPECIAL_CONSTRAINTS] ### GENERATION DIRECTIVES: 1. **Never Invent or Hallucinate Details**: Inspect the actual repository files (`package.json`, config files, folder structure, test scripts) before documenting any command or pattern. 2. **Review Existing Instructions**: If a `CLAUDE.md` or instruction file already exists, review it, identify obsolete commands or gaps, and produce an improved synthesis rather than blindly overwriting. 3. **Structure of the Output `CLAUDE.md`**: - **Project Overview**: Mission, high-level business logic, and tech stack summary. - **Architecture & Directory Structure**: Key directories, module boundaries, entry points, and data flow. - **Build, Test & Development Commands**: Exact terminal commands for installing dependencies, running local dev server, executing unit/integration tests, linting, formatting, and building for production. - **Coding Style & Conventions**: Naming conventions, TypeScript strictness, state management rules, file naming patterns, error handling conventions, and import grouping rules. - **Testing & Verification Standards**: Required test coverage, mocking practices, and how to verify changes before committing. - **Security & Environment Variables**: Handling of secret keys, .env templates, sanitization, and permission boundaries. - **Important Constraints & Antipatterns**: Explicit list of things Claude must NEVER do (e.g., blanket try/catches, direct database mutations in views, using deprecated packages). - **Monorepo / Nested Instructions**: If sub-packages exist, specify when and where nested `CLAUDE.md` files are justified. Generate the complete, ready-to-save `CLAUDE.md` in clean markdown format.
