Gitignore Builder

Build and merge repository .gitignore files or global gitignore files using templates from github/gitignore with smart target separation.

When to Use

Invoke this skill when:

• User explicitly requests /gitignore or asks to create/update a .gitignore
• User asks to create/update a global gitignore or personal git excludes file
• Detecting git init or a newly cloned repo without .gitignore
• User mentions ignoring files, not wanting to track certain files
• Observing git status output with files that should typically be ignored (e.g., node_modules/, .env, __pycache__/, *.log)

Workflow

Step 1: Determine Target Mode and Location

Choose the target mode before detecting templates. Do not mix repo and global ignore rules by default.
