validate-cr-annotations

What problem does it solve?

This skill enforces the mandatory verification protocol for MTG Comprehensive Rules annotations. Every CR number must be verified against docs/MagicCompRules.txt before entering the codebase, preventing incorrect annotations from being committed.

Core Features & Use Cases

• Verification protocol: For every CR number you are about to write, run grep to locate the line in docs/MagicCompRules.txt.
• Batch verification: When multiple CR annotations are updated, verify all at once with a small loop.
• Format and validation guidance: Ensures the CR prefix, numbering, and sub-rule letters exist and match the official text before integration.
• Use case: Prevents erroneous CR annotations in engine code during reviews and commits.

Quick Start

Before adding a CR annotation, grep the target rule in docs/MagicCompRules.txt to confirm its existence and alignment with the intended text.
