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.

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 | $0.00061 | $0.02016 |
| Opus 5 | $0.00030 | $0.01008 |
| Sonnet 5 | $0.00012 | $0.00403 |
| Haiku 4.5 | $0.00006 | $0.00202 |
Grade A, and why
architecture-diagram 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 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.
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 — 223 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Architecture Diagram — Self-Contained HTML+SVG Diagrams
Create professional technical architecture diagrams as single self-contained HTML files with inline SVG graphics and CSS styling. The output renders correctly when opened directly in any modern browser — no build step, no JavaScript framework, no external images.
When to use
- System, infrastructure, cloud, security, or network-topology diagrams.
- A shareable, presentation-ready visual artifact is the deliverable.
- Dark-theme technical aesthetic is desired.
For methodology (what to draw at each level), pair with architecture/c4-model;
for lightweight in-repo text diagrams, use tooling/mermaid. This skill covers
the rendered artifact case.
Workflow
- Copy
resources/template.htmlas the starting point. - Customize the
<title>, header text, and footer metadata. - Adjust the SVG
viewBoxif needed (default1000 x 680). - Add/reposition component boxes using the component pattern below.
- Draw connection arrows early in the SVG (after the background grid) so they render behind boxes.
- Update the three summary cards and legend.
- Deliver one
.htmlfile.

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.

architecture-diagram is a skill published in the GitHub repository ulises-jeremias/agent-toolkit (17 stars, last pushed today), licensed MIT. It adds 61 tokens to every session and 2,016 once invoked, about $0.0003 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 2026-08-30.
