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 | $0.00016 | $0.00215 |
| Opus 5 | $0.00008 | $0.00108 |
| Sonnet 5 | $0.00003 | $0.00043 |
| Haiku 4.5 | $0.00002 | $0.00021 |
Grade A, and why
Draw.io Architect 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 10d 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
When to use
Use this skill when the user asks to "visualize the architecture," "draw a flow," or "create a system diagram."
Instructions
- Format: Always output diagrams in the
mxfileXML format used by draw.io. - Naming: Save files with the
.drawioextension. - Styling: Use consistent styling with 'Rounded' rectangles and 'Orthogonal' connectors.
- Icons: Use standard icons for common components; for cloud infrastructure, reference AWS or similar icon sets if available.
- Updating: If a
.drawiofile already exists, read the XML and modify only the necessarymxCellelements rather than regenerating from scratch.
Example
User: "Draw a diagram of a web app with a React frontend and a FastAPI backend." Agent: [Generates valid XML and saves it to architecture.drawio]
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.

Draw.io Architect is a skill published in the GitHub repository vivek-viswanat/dev-arsenal (4 stars, last pushed 5mo ago), licensed MIT. It adds 16 tokens to every session and 215 once invoked, about $0.0001 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.
