gitignore-generator_skill

Overview

This skill generates comprehensive .gitignore files tailored to the technologies, frameworks, and environments you specify. It produces a single .gitignore output organized with clear section headers, deduplicated patterns, and sensible defaults for IDEs, OS files, environment secrets, build outputs, and test artifacts. Use natural language triggers like "create gitignore" or "gitignore for <stack>" to produce a ready-to-add file.

How this skill works

When invoked, the skill selects template blocks for the requested stacks (Node, Python, Go, Java, React/Next, Docker, Rust, Data Science, etc.). It merges multiple templates by deduplicating identical patterns, grouping related entries (dependencies, build, IDE, environment, tests), and adding section headers. The final output follows one-pattern-per-line syntax and includes common negations or exceptions where appropriate.

When to use it

• Starting a new project and you need a clean .gitignore for your stack
• Combining multiple frameworks or environments (e.g., Node + Docker + React)
• Standardizing .gitignore across a team or mono-repo
• Adding missing ignores for IDE files, OS artifacts, or environment files
• Generating .gitignore quickly from a short natural-language prompt

Best practices

• Specify all relevant stacks and tools in the prompt so the generator can combine templates correctly
• Review generated file for project-specific files that must not be ignored (remove broad patterns if needed)
• Keep a tracked example like .env.example to document required env vars while ignoring real .env files
• Use negation (!) only for intentional tracked files such as .vscode/settings.json or .env.example
• Regenerate when you add new build tools, languages, or CI systems to avoid leaking build artifacts

Example use cases

• "Create gitignore for a Next.js TypeScript app" — merges Node, Next.js, and TypeScript patterns
• "Generate .gitignore for a Python FastAPI project" — includes virtualenv, pytest/coverage, and IDE ignores
• "Gitignore for Go microservice with Docker" — combines Go binaries, vendor, Docker-related ignores, and common IDE/OS files
• "Create gitignore for full-stack Node + React + Docker" — deduplicates node_modules, build outputs, environment files, and Docker context exclusions
• "Generate .gitignore for data science project" — ignores data/, models/, Jupyter checkpoints, venv, and large binary artifacts
