Best for Solo founders who want their agent to write tighter copy and documents

This page lists the Agent Skills on my site that help a coding agent write, cut or format text, sorted by total installs on skills.sh. I read every skill file by file to rate its access (Low, Medium or High), and each skill page shows the security audits from skills.sh.

Start with caveman if you want shorter agent answers that still keep code, paths, numbers and errors. For landing, pricing and feature pages, Copywriting writes around one primary action and flags missing proof instead of inventing it. Both have Low access.

If your drafts tend to grow, Paperthin adds small skills like debloat and dedash that cut words and strip em dashes. For Word files, Word Documents (DOCX) creates and redlines documents with tracked changes.
