What problem does it solve? Keeping a large tree of markdown knowledge files consistent, linked, and error-free is difficult as the tree grows. This Skill automates the detection of orphaned files, formatting violations, broken links, and invalid card or combo data across the entire ygo-skills knowledge base. ## Core Features & Use Cases - Markdown Linting: Runs mdcheck.py to enforce bullet-point-only formatting, a 200-line file limit, and tree connectivity so no file is orphaned. - Catalog and Combo Validation: Runs catalogcheck.py and combocheck.py to verify card IDs against the cards.cdb SQLite database, enforce hand-trap criteria, and check combo material accounting and phase order. - Self-Evolution Workflow: Provides shared adherence rules and a SMART evaluation loop so that when a workflow fails, the root-cause skill file is updated automatically. - Use Case: After adding new deck experience files, invoke this Skill to verify every markdown is linked from a parent SKILL.md, under 200 lines, and passes all validation scripts before committing. ## Quick Start Ask the AI to run the self-evolve check on the ygo-skills tree and fix any structural or validation problems it finds.
