Cursor IDE

Same rules mechanism as Cursor Composer — Composer is Cursor's agent mode within the same IDE, sharing .cursor/rules/.

Add the .cursor/rules/agents.mdc pointer rule described in cursor-composer.md once; it applies to both chat/Tab completions and Composer/Agent mode.
Check Settings → Rules in the IDE to confirm the rule is active and alwaysApply: true (so it's loaded on every request, not just glob-matched files).
If migrating an existing project off legacy .cursorrules, move its content into AGENTS.md/SKILLS.md first, then replace .cursorrules with the pointer .mdc file — don't maintain both.
