Diagram Design is a tool for creating editorial-style diagrams as self-contained HTML and SVG files, covering layouts such as flows, system architectures, Sankey diagrams, maps, and schemas. Designers and coding-agent users can use it to produce branded static diagrams or redraw Mermaid and draw.io sources. The catalogue commands, plugin, and skill provide the agent workflow for generating these diagrams.
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 | $0.00009 | $0.00225 |
| Opus 5 | $0.00005 | $0.00112 |
| Sonnet 5 | $0.00002 | $0.00045 |
| Haiku 4.5 | $0.00001 | $0.00022 |
Grade A, and why
doctor 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 9d 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
Run environment diagnostics for Diagram Design by following skills/diagram-design/references/doctor.md. Treat that reference as the source of truth and do not reimplement its logic here.
Full argument string: $ARGUMENTS
Required behavior
- Locate and apply the exact checks and output contract from
references/doctor.md. - Keep this command read-only: do not install dependencies, do not edit files, and do not run destructive git operations.
- If a check command fails, capture stderr, mark the check
warnorfailper the reference, and continue remaining checks. - Print the compact summary line plus per-check statuses, and include
Next actionsonly when needed. - If
--jsonis passed, append the structured JSON block defined by the reference.
Report only verified results from this run.
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.

doctor is a command published in the GitHub repository cathrynlavery/diagram-design (37,301 stars, last pushed yesterday), licensed MIT. It adds 9 tokens to every session and 225 once invoked, about $0.0000 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.
