A diagram-making skill for creating or editing diagrams such as flowcharts, architecture diagrams, database relationship diagrams, sequence diagrams, mockups, and wireframes. It also covers draw.io files and exporting diagrams to common image or document formats.

Use it when creating system diagrams, process charts, data models, interface sketches, or draw.io exports.

It gives the agent a defined way to handle visual explanations instead of treating diagram requests like ordinary text or code tasks.

Token cost

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	$0.00075	$0.06706
Opus 5.5	$0.00030	$0.02682
Sonnet 5.5	$0.00015	$0.01341
Haiku 4.5	$0.00007	$0.00671

Security

Grade A, and why

drawio scanned grade A with 1 finding 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 27d 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

This uses only Node.js built-in modules (`zlib`, `child_process`) — no external dependencies.

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.
