Markdown Formatter

This skill appears to be what it claims (a markdown formatter) and does not request credentials or external network access, but the shipped code contains numerous programming errors and questionable regex/logic that could cause crashes or incorrect formatting. Before installing or running it: - Review and fix the code locally (notably STYLE_GUIDES object syntax errors, undefined variables like opts in fixListMarkers, malformed regexes and replacement logic). The package as-is may fail at runtime. - Run the included test.js in a sandbox/container to observe behavior. - Do not pass sensitive system file paths to formatBatch unless you trust the skill; it will read any file the process has permission to read. Consider limiting file paths or running formatting only on files you explicitly supply. - Because the repository/source is unknown, prefer running it in an isolated environment and consider obtaining the package from a trusted upstream repository (or replacing it with a well-known formatter like Prettier or remark) if you need production use. Confidence is medium: intent is clear and coherent, but code quality issues reduce confidence that the implementation is safe to run without review.
