What problem does it solve? Markdown documents often accumulate inconsistent formatting: mixed list markers, irregular heading styles, trailing whitespace, and uneven spacing. This Skill normalizes and cleans markdown content automatically according to a chosen style guide, so documentation stays consistent without manual editing. ## Core Features & Use Cases - Style-Guided Formatting: Format markdown against CommonMark, GitHub Flavored Markdown, or custom rules with configurable heading, list, code block, emphasis, and link styles. - Linting & Validation: Detect heading hierarchy skips, inconsistent list markers, and other issues without modifying the source content. - Batch Processing: Format multiple markdown files in one run with per-file results, warnings, and aggregate statistics. - Use Case: You inherit a project with dozens of inconsistently formatted README and docs files. Run formatBatch with the GitHub style to normalize all of them at once and review the warnings report. ## Quick Start Ask the agent to format your markdown file with the GitHub style guide by running the markdown-formatter skill's formatMarkdown function on your document content.
