IF A SKILL APPLIES TO YOUR TASK, YOU DO NOT HAVE A CHOICE. YOU MUST USE IT.

This is not negotiable. This is not optional. You cannot rationalize your way out of this.

⛔ 3-FILE RULE: HARD GATE (NON-NEGOTIABLE)

DO NOT read/edit >3 files directly. PROHIBITION, not guidance.

≤3 files → Direct OK (if user requested)
>3 files → STOP. Launch agent. VIOLATION = 15x context waste.

Applies to: Read, Grep/Glob (>3 matches to inspect), Edit, or any combination >3.
