At a glance

Uses the Defuddle CLI to pull clean, readable Markdown, JSON or metadata from web pages, stripping navigation, ads and clutter to save tokens.

  • Reading a standard web page without its navigation and ads
  • SKILL.md covers Usage and Output formats
  • Calls npm
  • Saving an article as clean Markdown in a local file

What it does

This skill tells the agent to use the Defuddle command-line tool instead of a generic fetch tool when it needs the readable content of a standard web page. The tool removes navigation, ads and other clutter, which cuts the number of tokens the agent has to read. If it is missing, it can be installed globally with npm.

The basic call is `defuddle parse` with a URL and the `--md` flag for Markdown, with `-o` to save the result to a file such as content.md. The `-p` flag pulls out a single metadata property, for example title, description or domain. Output can also be JSON holding both the HTML and the Markdown, or plain HTML when no format flag is given.

When your agent uses it

  • Reading a standard web page without its navigation and ads
  • Saving an article as clean Markdown in a local file
  • Pulling a page's title, description or domain
  • Cutting the token cost of fetching web content

Example prompts

  • “Fetch https://example.com/blog/launch as clean Markdown and save it to content.md.”
  • “Get the title and domain of https://example.com/docs/intro.”
  • “Read https://example.com/essay with defuddle instead of WebFetch to save tokens.”

Requirements

  • The Defuddle CLI, installed with npm install -g defuddle
  • Network access to fetch pages

What it can do on your machine

Read from SKILL.md and the folder at commit 3ccff53. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Defuddle loads about 208 tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 70 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~17
When it runs · the whole SKILL.md, loaded when a task matches
~208

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
