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.

Fable 5.1 $0.00068 $0.02111
Opus 5.5 $0.00027 $0.00844

Security

Grade A, and why

url-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 6d ago.

The scan reads SKILL.md. This mod also ships 41 executable files (scripts/lib/adapters/generic/index.ts, scripts/lib/adapters/hn/index.ts, scripts/lib/adapters/index.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Origin

This is a copy

88% identical to baoyu-url-to-markdown — 27 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.

URL to Markdown

Fetches any URL via fetch CLI (Chrome CDP + site-specific adapters) and converts it to clean markdown.

User Input Tools

When this skill prompts the user, follow this tool-selection rule (priority order):

  1. Prefer built-in user-input tools exposed by the current agent runtime — e.g., AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.
  2. Fallback: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question.
  3. Batching: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order.

Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes.

CLI Setup

Important: The CLI source is vendored in {baseDir}/scripts/lib. scripts/package.json installs only third-party runtime dependencies.

Agent Execution Instructions:

  1. Determine this SKILL.md file's directory path as {baseDir}
  2. Resolve ${BUN} runtime: if bun installed → bun; else suggest installing Bun
  3. If {baseDir}/scripts/node_modules does not exist, run ${BUN} install --cwd {baseDir}/scripts
  4. ${READER} = {baseDir}/scripts/fetch
  5. Replace all ${READER} in this document with the resolved value

Preferences (EXTEND.md)

Check EXTEND.md in priority order — the first one found wins:

Priority Path Scope
1 .config/skills/url-to-markdown/EXTEND.md Project
2 ${XDG_CONFIG_HOME:-$HOME/.config}/skills/url-to-markdown/EXTEND.md User home
Result Action
Found Read, parse, apply settings
Not found MUST run first-time setup (see below) — do NOT silently create defaults

EXTEND.md supports: download media by default, default output directory.

First-Time Setup ⛔ BLOCKING

When EXTEND.md is not found, you MUST use AskUserQuestion to gather preferences before creating EXTEND.md. NEVER create EXTEND.md with silent defaults. Generation is BLOCKED until setup completes. Batch all three questions into a single call:

What ships with it

47 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
