AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

Defuddle is a CLI utility designed to transform raw HTML from web pages into structured Markdown. By stripping away navigation menus, advertisements, and other non-essential elements, it provides a cleaner input for AI agents, effectively reducing token consumption during processing. It supports multiple output formats, including Markdown, JSON, and specific metadata extraction.

What it does

Converts HTML web content into clean Markdown format
Removes website clutter like navigation bars and ads
Extracts specific metadata properties such as title, description, or domain
Supports outputting content directly to files
Provides options for JSON output containing both HTML and Markdown

When to use it

When you need to ingest web content into an AI agent while minimizing token usage
When you want to extract specific metadata from a webpage
When you need to clean up messy HTML for documentation or archiving purposes

Advantages

Reduces token usage by removing unnecessary web page elements
Simplifies web content into a standard Markdown format
Flexible output options for different data requirements

Usage examples

“Extract the content of a webpage as markdown using defuddle.”: The agent executes the command to parse the URL and returns the cleaned Markdown text.
“Save the markdown content of a webpage to a file named content.md.”: The agent runs the command with the output flag to save the processed content to the specified file.
“Get the title of a webpage using defuddle.”: The agent uses the property flag to extract and return only the title metadata.

Documentation by Steph Ango (Obsidian)

Use Defuddle CLI to extract clean readable content from web pages. Prefer over WebFetch for standard web pages — it removes navigation, ads, and clutter, reducing token usage.

If not installed: npm install -g defuddle

Usage

Always use --md for markdown output:

defuddle parse <url> --md

Save to file:

defuddle parse <url> --md -o content.md

Extract specific metadata:

defuddle parse <url> -p title
defuddle parse <url> -p description
defuddle parse <url> -p domain

Output formats

Flag	Format
`--md`	Markdown (default choice)
`--json`	JSON with both HTML and markdown
(none)	HTML
`-p <name>`	Specific metadata property
