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.

Security

Grade A, and why

excalidraw-diagram-generator 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.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/add-arrow.py, scripts/add-icon-to-diagram.py, scripts/split-excalidraw-library.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.

Excalidraw Diagram Generator

A skill for generating Excalidraw-format diagrams from natural language descriptions. This skill helps create visual representations of processes, systems, relationships, and ideas without manual drawing.

When to Use This Skill

Use this skill when users request:

  • "Create a diagram showing..."
  • "Make a flowchart for..."
  • "Visualize the process of..."
  • "Draw the system architecture of..."
  • "Generate a mind map about..."
  • "Create an Excalidraw file for..."
  • "Show the relationship between..."
  • "Diagram the workflow of..."

Supported diagram types:

  • 📊 Flowcharts: Sequential processes, workflows, decision trees
  • 🔗 Relationship Diagrams: Entity relationships, system components, dependencies
  • 🧠 Mind Maps: Concept hierarchies, brainstorming results, topic organization
  • 🏗️ Architecture Diagrams: System design, module interactions, data flow
  • 📈 Data Flow Diagrams (DFD): Data flow visualization, data transformation processes
  • 🏊 Business Flow (Swimlane): Cross-functional workflows, actor-based process flows
  • 📦 Class Diagrams: Object-oriented design, class structures and relationships
  • 🔄 Sequence Diagrams: Object interactions over time, message flows
  • 🗃️ ER Diagrams: Database entity relationships, data models

Prerequisites

  • Clear description of what should be visualized
  • Identification of key entities, steps, or concepts
  • Understanding of relationships or flow between elements

Step-by-Step Workflow

Step 1: Understand the Request

Analyze the user's description to determine:

  1. Diagram type (flowchart, relationship, mind map, architecture)
  2. Key elements (entities, steps, concepts)
  3. Relationships (flow, connections, hierarchy)
  4. Complexity (number of elements)

Step 2: Choose the Appropriate Diagram Type

User Intent Diagram Type Example Keywords
Process flow, steps, procedures Flowchart "workflow", "process", "steps", "procedure"
Connections, dependencies, associations Relationship Diagram "relationship", "connections", "dependencies", "structure"
Concept hierarchy, brainstorming Mind Map "mind map", "concepts", "ideas", "breakdown"
System design, components Architecture Diagram "architecture", "system", "components", "modules"
Data flow, transformation processes Data Flow Diagram (DFD) "data flow", "data processing", "data transformation"
Cross-functional processes, actor responsibilities Business Flow (Swimlane) "business process", "swimlane", "actors", "responsibilities"
Object-oriented design, class structures Class Diagram "class", "inheritance", "OOP", "object model"
Interaction sequences, message flows Sequence Diagram "sequence", "interaction", "messages", "timeline"
Database design, entity relationships ER Diagram "database", "entity", "relationship", "data model"
