indent_style

Every non-blank line indents with the configured style (tabs or spaces). When style: spaces, optional width enforces a multiple.

Check-only: tab-width-aware reindentation is language-specific. Pair with your editor’s “reindent on save” for remediation.

Options

Option	Type	Required	Default	Description
style	one of tabs | spaces	yes		Required indentation style: tabs rejects any leading space; spaces rejects any leading tab.
width	integer (>= 1)		null	When style: spaces, the leading-space count on every non-blank line must be a multiple of this. Ignored for style: tabs.

Plus the common paths, level, id, and when fields. This table is generated from the JSON Schema; option types and defaults are authoritative.
