What is create-drawio-diagram?

A diagram-making guide for Draw.io (also called diagrams.net), a visual editor for architecture diagrams. It uses reusable templates and saves editable source files plus exports in a dedicated diagrams/ folder.

It helps create capability maps and target or solution architecture diagrams showing systems, data, integrations, technologies, and dependencies.

It keeps architecture diagrams consistent and makes sure stakeholders receive files they can edit. It also avoids scattering diagram files beside the main document.

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high System Prompt Leakage · line 271
Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.

Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.

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	$0.00090	$0.09954
Opus 5.5	$0.00036	$0.03982
Sonnet 5.5	$0.00018	$0.01991

Security

Grade A, and why

create-drawio-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 1mo ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/check-solution-architecture-routing.py, scripts/sanitize-drawio-svg.py, scripts/test_capability_context_diagram.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Create Draw.io Diagram

Quick Start

Create editable Draw.io diagrams for architecture deliverables using the templates in templates/ and the visual rules in STYLE.md.

Use this skill when a generated architecture document needs diagrams that stakeholders can edit in Draw.io or diagrams.net. Always create a diagrams/ subfolder next to the supporting document and store every generated .drawio source and same-basename export there. Never place diagram files beside the supporting document.

Diagram Templates

Use these templates as starting points:

templates/capability-map.drawio for a layered map of capabilities across Channel, Engagement Services, Integration, and Enterprise Foundation, with three cross-cutting columns
templates/capability-overview.drawio for actors, neighboring capabilities, and external dependencies
templates/target-architecture-diagram.drawio for a simple target architecture overview across capabilities, applications, data, integrations, and technology
templates/solution-architecture-diagram.drawio for a simple solution architecture overview across channels, components, integrations, data stores, and external systems
templates/data-architecture-diagram.drawio for a simple data architecture overview across source systems, owners, consumers, integrations, and governance
templates/data-flow.drawio for data flow diagrams with process stages across the top, systems as horizontal lanes, and labeled data movements between lanes
templates/application-component-view.drawio for applications, services, components, platforms, and responsibilities
templates/conceptual-data-model.drawio for canonical data objects and relationships
templates/integration-design.drawio for component maps organized in vertical layers: Public Internet, Frontend, Engagement, Integration, and Enterprise Foundation (Backoffice)
templates/integration-flow.drawio for producers, consumers, interfaces, triggers, protocols, and sequence
