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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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@sha256:e136f7ee29454706The line at the top of this page pins the label git:20260807.b89e550, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
