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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00144 | $0.00811 |
| Opus 5 | $0.00072 | $0.00405 |
| Sonnet 5 | $0.00029 | $0.00162 |
| Haiku 4.5 | $0.00014 | $0.00081 |
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 11d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web to Markdown
Fetch a URL and save its content as a clean .md file in the project's docs/ directory.
Quick Start
Run the bundled script:
python3 <skill-path>/scripts/fetch_markdown.py <url> [--output <path>]
The script automatically:
- Tries
Accept: text/markdownheader (Cloudflare Markdown for Agents) - Falls back to HTML fetch + conversion if markdown not available
- Saves to
docs/<url-derived-name>.mdby default
Options
| Flag | Description | Default |
|---|---|---|
--output, -o |
Custom output path | docs/<name>.md |
--api-key |
Cloudflare API key | $CLOUDFLARE_API_KEY env |
--zone-id |
Cloudflare Zone ID | $CLOUDFLARE_ZONE_ID env |
Usage Patterns
Single page
python3 <skill-path>/scripts/fetch_markdown.py "https://react.dev/reference/react/useState"
# → docs/reference_react_useState.md
Custom output path
python3 <skill-path>/scripts/fetch_markdown.py "https://docs.example.com/api" --output docs/api/example-api.md
Multiple pages (run sequentially)
python3 <skill-path>/scripts/fetch_markdown.py "https://docs.example.com/getting-started" --output docs/getting-started.md
python3 <skill-path>/scripts/fetch_markdown.py "https://docs.example.com/api-reference" --output docs/api-reference.md
With Cloudflare API key
export CLOUDFLARE_API_KEY="your-key"
python3 <skill-path>/scripts/fetch_markdown.py "https://example.com/docs"
Conversion Strategy
- Cloudflare sites: If the site has Markdown for Agents enabled, the server returns clean markdown directly — no client-side parsing needed. This produces the highest quality output.
- All other sites: HTML is fetched and converted locally. The script extracts
<main>,<article>, or<body>content, strips nav/footer/scripts, and converts to markdown. Quality is good for documentation sites but may include some noise for complex layouts.
Output Format
Each saved file includes source metadata:
What ships with it
2 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.

web-to-markdown is a skill published in the GitHub repository rungchan2/frontend-skills (2 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 144 tokens to every session and 811 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
