Cursor User Rules have no effect on Inline Edit (Cmd+K) or Tab completions

Cmd+K edits ignore style preferences that Agent follows

Cause

User Rules are used only by Agent (Chat), and rules in general do not affect Tab or the other AI features.

Enforce must-have conventions in tooling that runs on every change, such as a formatter and linter, and restate the preference in the Cmd+K prompt.

npx prettier --write . && npx eslint --fix .

Affects: Cursor editor, as of 2026-10

Have your agent know this before it fails
