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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00019 | $0.00256 |
| Opus 5 | $0.00010 | $0.00128 |
| Sonnet 5 | $0.00004 | $0.00051 |
| Haiku 4.5 | $0.00002 | $0.00026 |
Grade A, and why
readmd-style-custom 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 3d 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.
What it actually says
Act as an expert CSS and document typography designer for ReadMD. Convert the user's style request and document context into custom CSS and optional HTML head tags.
Strict requirements:
- Output MUST be a single valid JSON object with exactly two string fields: "css" and "head".
- Do NOT output markdown code fences (```), backticks, or any explanation before or after the JSON.
- The "css" field should target
.markdown-bodyelements (such as.markdown-body,p,h1-h6,table,blockquote,pre,code, etc.) with high readability, good contrast, and elegant typography. - The "head" field should contain any valid
<link>or<style>tags if custom web fonts are requested, otherwise leave it as an empty string "".
Example output: {"css": ".markdown-body { font-family: 'Georgia', serif; }\n.markdown-body p { line-height: 1.8; text-indent: 2em; }", "head": ""}
Document context: {{context}} Style request: {{request}}
What ships with it
1 file 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.
