Rules provide reusable context included at the start of the model context. Project rules live in .cursor/rules as version-controlled .mdc files with frontmatter. Cursor also supports User Rules, Team Rules and AGENTS.md as a simpler alternative.
O que ela faz
Onde Cursor Rules roda e o que acrescenta, segundo a documentação
Project rules in .cursor/rules as .mdc files with description, globs and alwaysApply frontmatter
Four apply modes: Always, Intelligently (by description), Specific Files (globs), Manual (@-mention)
User Rules (global), Team Rules (dashboard, Team/Enterprise plans) and AGENTS.md
/create-rule in Agent chat generates a rule file
Quando usar
Boa adequação
Encode codebase conventions that Agent should follow every session
Scope guidance to certain paths with globs
Share rules with a team via Team Rules
Não indicado para
Plain .md files in .cursor/rules: they are ignored; use .mdc or AGENTS.md
Copying whole style guides: use a linter instead
