This skill gives Claude six directives for building an .editorconfig file. It must analyze your project structure and file types, follow your stated preferences, add universal best practices such as charset, line endings, trailing whitespace and final newlines, and cover every file type with glob patterns. The answer has two parts: one code block with the file, and a rule-by-rule explanation.

The SKILL.md hard-codes two preferences under a User Preferences heading: indent with spaces, two spaces wide. Tell Claude if you want something else. It bundles no scripts and names no tools or keys.

Good for

Developers starting a project who need consistent editor settings
Teams with mixed editors and line endings
Anyone who wants each .editorconfig rule explained

Questions

What does the editorconfig skill do?

It makes Claude write a complete .editorconfig for your project. Claude looks at your file types, applies your preferences and good defaults, and explains each rule.

Can I use tabs or four spaces?

The SKILL.md lists spaces and a size of 2 under User Preferences, and a directive says to follow all explicit user requirements. Say what you want in your prompt. The file does not say which wins if they differ.

Does it save the file for me?

SKILL.md says the output is a code block plus an explanation. It does not say Claude writes the file to disk, so ask for that if you want it.

Why does the example turn off trimming for Markdown?

The example's explanation says trailing whitespace can be significant in Markdown, for example for hard line breaks.

Is it safe?

It bundles no scripts and defines no commands to run. If you ask Claude to save the file, it adds an .editorconfig to your project, which changes how editors format code, so review it. The awesome-copilot README says its customizations come from third-party developers and asks you to inspect them before installing.
