Generate .editorconfig

When to use this skill

When starting work on a new repository or adding an .editorconfig to an existing project that lacks one.

How it works

Creates a minimal .editorconfig file with sensible defaults. The generated config follows the repository's existing style when possible.

Process

• Check if .editorconfig already exists - if so, update it

• Examine existing files in the repo to detect coding style:

• Look at indentation (spaces vs tabs), indent size

• Check line ending conventions

• Identify file types that may need special handling

• Generate appropriate, minimal .editorconfig content with no unnecessary duplication.

• Write the file to the repository root

Generated Config Structure

root = true

[*] indent_style = space indent_size = <detected or 4> end_of_line = lf charset = utf-8 trim_trailing_whitespace = true insert_final_newline = true

[*.md] max_line_length = 78

[*.json] indent_size = 2

Best Practices

• Always set root = true at the top

• Use [*] for universal settings

• Add specific file type overrides after universal settings

• Keep it minimal - only specify what differs from editor defaults
