Agent Skills: markdown-table-validator

Detect and fix Markdown (GFM) tables that won't render on GitHub or the VS Code preview — unescaped pipes inside cells, header/separator column-count mismatch, indented (code-block) tables, and misplaced alignment colons. Use when a markdown table renders as raw text, when cleaning LLM-generated docs in bulk, or when auditing a repo's tables before a commit. TRIGGERS - markdown table broken, table not rendering, fix markdown table, escape pipe in table, GFM table, table renders as text, validate markdown tables.
