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 | $0.00046 | $0.02735 |
| Opus 5 | $0.00023 | $0.01367 |
| Sonnet 5 | $0.00009 | $0.00547 |
| Haiku 4.5 | $0.00005 | $0.00274 |
Grade D, and why
artifact-preview scanned grade D with 3 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 12d 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.
**⚠️ Pitfall — tilde in curl `@` syntax:** `curl --data-binary @~/path` fails because `~` doesn't expand through curl's `@` filename operator. Always `cd` to the directory first, or copy to a temp file with absolute path Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

🪽 Artifact Preview v4.3 — Live Preview + Smart History 🏆
One-line install. Instant visual feedback. Every version safely saved. Zero "where did my work go?" 🔥
What This Is
This skill shows the human what you built — a UI, a dashboard, a page, a result. Visually. Instantly.
It is not for agents to read content from. The Chrome window is for human eyes only. Extract data directly from the source if needed.
⚠️ INCOMPATIBLE with chrome-devtools. Never use both simultaneously.
🚀 One-Line Install
curl -fsSL https://raw.githubusercontent.com/ChuckSRQ/awesome-hermes-skills/v4.3/artifact-preview/install.sh | bash
Server starts automatically. You're ready to go. ✨
How to Use
Step 1 — Generate complete, polished, self-contained HTML/CSS/JS (see Design Standards below).
Step 2 — Save + trigger reload:
cd ~/artifact-preview
cat > artifact.html << 'ENDOFHTML'
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Your Clear Title Here</title>
</head>
<body>
<!-- your complete content -->
</body>
</html>
ENDOFHTML
# Saves + archives + live reload — instant! ⚡
curl -X POST http://localhost:8765/update \
-H "Content-Type: text/html; charset=utf-8" \
--data-binary @artifact.html -s -o /dev/null
Step 3 — Open the preview:
bash ~/artifact-preview/open-chrome.sh # auto mode = magic 🪄
Pro tip: Always include <title> and <h1> — history labels depend on them.
⚠️ Static asset trap — images and subdirectories: If your artifact HTML references subdirectories or image files (e.g. <img src="slides/slide-01.jpg">), those files MUST be inside ~/artifact-preview/ — the server only serves from its own directory. Files elsewhere on the filesystem are invisible even if they exist. Always copy assets to ~/artifact-preview/ before POSTing.
⚠️ Pitfall — tilde in curl @ syntax: curl --data-binary @~/path fails because ~ doesn't expand through curl's @ filename operator. Always cd to the directory first, or copy to a temp file with absolute path first:
cp ~/artifact-preview/history/myfile.html /tmp/myfile.html
curl -X POST http://localhost:8765/update \
-H "Content-Type: text/html; charset=utf-8" \
--data-binary @/tmp/myfile.html -s -o /dev/null
What ships with it
10 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.

artifact-preview is a skill published in the GitHub repository ChuckSRQ/awesome-hermes-skills (76 stars, last pushed 4mo ago), licensed MIT. It adds 46 tokens to every session and 2,735 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it D with 3 findings (sends data to an external url, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
