The instructions your model reads when the skill loads.
Automated markdown validation and fixing using markdownlint-cli2.
1. Run auto-fix → markdownlint-cli2 --fix <file>
2. Check remaining → markdownlint-cli2 <file>
3. Fix manually → str_replace for structural issues
4. Verify → markdownlint-cli2 <file> (should show 0 errors)
Expected results: Auto-fix resolves 70-90% of issues. Remaining 3-5 issues require manual correction.
