Author CLI surfaces as agent-facing documentation, especially `--help` and actionable error messages. Use with any language or parser design when adding or changing a CLI interface, improving help text or validation errors, moving command reference out of AGENTS.md / CLAUDE.md / a README / a skill and into CLI surfaces, or making errors suggest the corrected command line or tool call.

Extract clean markdown content from web pages using Defuddle CLI, removing clutter and navigation to save tokens. Use instead of WebFetch or the built in fetcher when the user provides a URL to read or analyze, for online documentation, articles, blog posts, YouTube videos, or any standard web page. Also use when the user asks to clip, save, or archive a web page to the repo or vault.
