Choose backticks or tildes, add an optional language tag, and automatically use a fence longer than any matching run inside the code.
The review follows the source or generated Markdown for this tool, checks structural handoff risks, and keeps CommonMark/GFM/host-specific boundaries visible before copy or export.

Review summary will appear here.
CommonMark defines the core syntax, while GitHub Flavored Markdown and publishing systems add extensions such as tables, task lists, autolinks, footnotes, front matter and renderer-specific raw-HTML behavior. This review is local and never fetches links.
Generate a fenced code block that remains valid even when the code itself contains backtick or tilde fences. The outer fence automatically grows beyond the longest conflicting run.
| Hazard | Longest run | Outer fence | Resolution |
|---|
Use a language identifier supported by your renderer. The generator only guarantees fence containment; syntax highlighting and filename display remain renderer-specific.
Markdown portability depends on the exact source and the renderer that consumes it.
Review fences, headings, links, extension syntax and generated output before publishing; source-level checks do not prove remote links or repository-specific style rules.
