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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00072 | $0.02160 |
| Opus 5.5 | $0.00029 | $0.00864 |
| Sonnet 5.5 | $0.00014 | $0.00432 |
| Haiku 4.5 | $0.00007 | $0.00216 |
Grade A, and why
baoyu-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 1mo 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.
This is a copy
100% identical to baoyu-url-to-markdown — 0 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 — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.
URL to Markdown
Fetches any URL via baoyu-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):
- Prefer built-in user-input tools exposed by the current agent runtime — e.g.,
AskUserQuestion,request_user_input,clarify,ask_user, or any equivalent. - 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.
- 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:
- Determine this SKILL.md file's directory path as
{baseDir} - Resolve
${BUN}runtime: ifbuninstalled →bun; else suggest installing Bun - If
{baseDir}/scripts/node_modulesdoes not exist, run${BUN} install --cwd {baseDir}/scripts ${READER}={baseDir}/scripts/baoyu-fetch- 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 | .baoyu-skills/baoyu-url-to-markdown/EXTEND.md |
Project |
| 2 | ${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-url-to-markdown/EXTEND.md |
XDG |
| 3 | $HOME/.baoyu-skills/baoyu-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.
What ships with it
48 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.

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.

baoyu-url-to-markdown is a skill published in the GitHub repository bestagentkits/agency-skills (24 stars, last pushed 3mo ago), licensed MIT. It adds 72 tokens to every session and 2,160 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings.
