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 | $0.00078 | $0.00884 |
| Opus 5.5 | $0.00031 | $0.00354 |
| Sonnet 5.5 | $0.00016 | $0.00177 |
| Haiku 4.5 | $0.00008 | $0.00088 |
Grade A, and why
archify_architecture 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 2d 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

archify_architecture diagram (uml-mcp plugin archify)
diagram_type: archify_architecture
Backend: plugin:archify (bundled with uml-mcp, on by default)
Output formats: html, svg
Architecture diagram with dashed colour-coded groups (security, frontend, backend, bus, workers, database, cloud), icon cards, a legend and labelled arrows; auto-laid out left-right or top-down, dark, light or auto, in classic, blueprint or flow presets. JSON nodes, groups, edges; html or svg
Load the workflow skill uml-mcp-diagrams and the focused guide skill://uml-mcp-guides/archify/SKILL.md. This file is notation only; it does not add an MCP tool.
Example prompt
Show our platform as an archify architecture with security, frontend, backend, message bus and database groups, blueprint preset.

Styling
Pass theme (auto, dark or light) to generate_uml / generate_uml_image, or set it in the source. auto follows the reader's system in the HTML page and is dark in static SVG and PNG.

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.

archify_architecture is a skill published in the GitHub repository antoinebou12/uml-mcp (109 stars, last pushed yesterday), licensed MIT. It adds 78 tokens to every session and 884 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings.
