Markdown Formatter

markpitt/claude-skills
232 installs22 stars
Summary

Cleans up markdown files according to standard conventions: ATX headers, consistent list markers, fenced code blocks with language tags, proper spacing between elements. The modular approach is nice, you load only the resource you need (headers, lists, code blocks, links, or spacing). Built with security in mind since it treats file contents as untrusted data, which matters if you're processing community contributions or auto-generated docs. Includes a validation script and works alongside existing linters. Won't check spelling or validate URLs, just handles structural formatting. Best for standardizing README files, cleaning up documentation before commits, or enforcing house style across a docs repo.

docx

jim60105/copilot-prompt

Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of 'Word doc', 'word document', '.docx', or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a 'report', 'memo', 'letter', 'template', or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation.
