Follow project structure standards, environment variable management, Content Collections setup, version control practices, and build/deployment conventions. Use this skill when setting up project structure, managing configuration files, organizing dependencies, or establishing development workflows. When working on project directory structure and organization, environment variable files (.env, .env.local, .env.production), Content Collections configuration (src/content/config.ts), package.json and dependency management, git commit messages and branching strategy, configuration files (astro.config.mjs, tsconfig.json), build and deployment setups, or documentation files (README.md, ADRs).
