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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00076 | $0.01343 |
| Opus 5.5 | $0.00030 | $0.00537 |
| Sonnet 5.5 | $0.00015 | $0.00269 |
| Haiku 4.5 | $0.00008 | $0.00134 |
Grade A, and why
static-web-artifacts-builder 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.
How it starts
The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Static Web Artifacts Builder
To build high-density static infographic artifacts, follow these steps:
- Initialize the project scaffold using
scripts/init-artifact.sh - Develop your artifact by editing the generated HTML file(s)
- Validate and finalize using
scripts/bundle-artifact.sh - Display artifact to user
Stack: Vanilla HTML5 + CSS3 (Grid/Flexbox) + inline SVG — zero runtime dependencies
Design & Style Guidelines
VERY IMPORTANT: To avoid what is often referred to as "AI slop", avoid excessive centered layouts, purple gradients, uniform rounded corners, and Inter font.
Infographic-Specific Constraints
- Density: Content-to-whitespace ratio ≥ 70:30. Maximize signal per pixel.
- Geometry: Layered/nested containers, shaped regions (clip-path, border-radius variations), gradient fills, subtle box-shadows — not flat uniform boxes.
- Iconography: Inline SVG icons for every major concept. No naked text labels.
- Color: Purposeful palette (3-4 hues + neutrals), encoding meaning (category, flow direction, severity). Define as CSS custom properties.
- Flows: Directional connectors with SVG arrowheads, curved paths, labeled edges. Architecture diagrams = layered tiers with bidirectional data flows, not flat node graphs.
- Layout math: CSS Grid with explicit
grid-template-columns/grid-template-rowsfractional allocations. No auto-spacing defaults. Every margin/padding intentional.
Quick Start
Step 1: Initialize Project
Run the initialization script to create a new static project:
bash scripts/init-artifact.sh <project-name>
cd <project-name>
This creates a minimal scaffold with:
- ✅ Template HTML with CSS custom properties (theming)
- ✅ CSS Grid + Flexbox layout utilities (inline
<style>) - ✅ Print-ready viewport meta configuration
- ✅ No node_modules, no package.json, no build toolchain
Step 2: Develop Your Artifact
Edit the generated index.html directly. Each HTML file = one page = one clear message.
What ships with it
4 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.

static-web-artifacts-builder is a skill published in the GitHub repository Mathews-Tom/armory (336 stars, last pushed today), licensed MIT. It adds 76 tokens to every session and 1,343 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-05.
