markdown-table-validator skillA
markdown-table-validator is agent-read markdown (skill) from terrylica/cc-skills: 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.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Markdown Table Validator Scan Markdown files for the structural problems that silently demote a GFM table to a plain paragraph on GitHub / VS Code preview, and optionally auto-escape the single most common cause (an unescaped `|` inside a cell). > **Self-Evolving Skill**: This skill improves through use. If the detector > misses a real broken-table case, the `--fix` heuristic guesses wrong, or a > path/flag has drifted — fix this file (and the detector SSoT) immediately, > don't defer. Only update for real, reproducible issues. ## Why tables break (the one rule that matters) GFM ignores whitespace between pipes, so **alignment is never the cause**. What breaks rendering is **structure** — overwhelmingly an **unescaped `|` inside a cell**. GFM's table tokenizer treats a `|` as a column delimiter _even inside a `` `code span` ``_, so a regex/code cell like `` `a | b | c` `` inflates that row's cell count and the whole table collapses. The fix — escaping it as `\|` — changes meaning, so **no formatter does it for you** (Prettier actively corrupts such tables: prettier#10164 / #11410). This skill detects it and can apply the escape under review. ## Quick start ```bash …

How to install
mdr add terrylica/cc-skills/markdown-table-validator@git:20260807.b89e550mdr add terrylica/cc-skills/markdown-table-validator@sha256:e136f7ee29454706Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
