web-to-markdown

web-to-markdown is a skill for Claude Code, Codex from softaworks/agent-toolkit. It costs 64 tokens per session (944 once invoked), scanned A, original, MIT.

A manually requested tool that turns web page URLs into clean Markdown text, including pages whose content appears only after JavaScript runs.

In plain words
What is it for?
Use it to convert one or more web pages into Markdown for notes, documentation, or further processing. It requires an explicit request naming this skill.
Why use it?
It removes the need to copy page text by hand or deal with messy menus and layout. It can extract the main readable content and save or print it.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-to-markdown scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

web-to-markdown

Convert web pages to clean Markdown by driving a locally installed browser (via web2md).

Hard trigger gate (must enforce)

This skill MUST NOT be used unless the user explicitly wrote exactly a phrase like:

  • use the skill web-to-markdown ...
  • use a skill web-to-markdown ...

If the user did not explicitly request this skill by name, stop and ask them to re-issue the request including: use the skill web-to-markdown.

What this skill does

  • Handles JS-rendered pages (Puppeteer → user Chrome).
  • Works best with Chromium-family browsers (Chrome/Chromium/Brave/Edge) via puppeteer-core.
  • Extracts main content (Readability).
  • Converts to Markdown (Turndown) with cleaned links and optional YAML frontmatter.

Non-goals

  • Do not use Playwright or other browser automation stacks; the mechanism is web2md.

Inputs you should collect (ask only if missing)

  • url (or a list of URLs)
  • Output preference:
    • Print to stdout (--print), OR
    • Save to a file (--out ./file.md), OR
    • Save to a directory (--out ./some-dir/ to auto-name by page title)
  • Optional rendering controls for tricky pages:
    • --chrome-path <path> (if Chrome auto-detection fails)
    • --interactive (show Chrome and pause so the user can complete human checks/login, then press Enter)
    • --wait-until load|domcontentloaded|networkidle0|networkidle2
    • --wait-for '<css selector>'
    • --wait-ms <milliseconds>
    • --headful (debug)
    • --no-sandbox (sometimes required in containers/CI)
    • --user-data-dir <dir> (login/session; use a dedicated profile directory)

Workflow

  1. Confirm the user explicitly invoked the skill (use the skill web-to-markdown).
  2. Validate URL(s) start with http:// or https://.
  3. Ensure web2md is installed:
    • Run: command -v web2md
    • If missing, instruct the user to install it (assume the project exists at ~/workspace/softaworks/projects/web2md):
      • cd ~/workspace/softaworks/projects/web2md && npm install && npm run build && npm link
      • Or: cd ~/workspace/softaworks/projects/web2md && npm install && npm run build && npm install -g .
  4. Convert:
    • Single URL → file:
      • web2md '<url>' --out ./page.md
    • Single URL → auto-named file in directory:
      • mkdir -p ./out && web2md '<url>' --out ./out/
    • Human verification / login walls (interactive):
      • mkdir -p ./out && web2md '<url>' --interactive --user-data-dir ./tmp/web2md-profile --out ./out/
      • Then: complete the check in the browser window and press Enter in the terminal to continue.
    • Print to stdout:
      • web2md '<url>' --print
    • Multiple URLs (batch):
      • Create output dir (e.g. ./out/) then run one web2md command per URL using --out ./out/
  5. Validate output:
    • If writing files, verify they exist and are non-empty (e.g. ls -la <path> and wc -c <path>).
  6. Return:
    • The saved file path(s), or the Markdown (stdout mode).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
