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

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 2 executable files (scripts/create_sample_diagrams.py, scripts/render_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.

How it starts

The opening of the file, as written. The whole thing — 189 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Diagram Generator

ACTION REQUIRED (execute immediately after reading)

  1. NOW: Confirm whether the current task falls within this skill's scope
  2. NOW: Read ../tool-index.md to verify tool availability and actual paths
  3. NEXT: If a tool is missing, invoke bootstrap — do not guess paths
  4. ACT: Enter the first step of the "Workflow" and execute — do not stop at the confirmation stage

Purpose

Create clear, editable diagrams from messy or structured inputs. Prefer text-based diagram source first so the result can be reviewed, versioned, and refined. Render to files only when the user asks for an image/PDF or when a downloadable artifact would materially help.

Default workflow

  1. Identify the user's intent, audience, and source material.
  2. Choose the diagram family and language using the decision table below.
  3. Normalize entities, relationships, labels, states, branches, and time/order information before writing diagram code.
  4. Generate concise, readable diagram source.
  5. Validate the syntax mentally and, when creating files, run scripts/render_diagram.py.
  6. Return the diagram source plus a short note about assumptions. When files are generated, include links to the output files.

Do not over-ask for clarification. If the request is underspecified, make reasonable assumptions and label them briefly.

Diagram language decision table

Use Mermaid unless another language is clearly better.

User wants Prefer Why
process flow, decision tree, simple swimlane Mermaid flowchart readable and easy to paste into Markdown
sequence of system/user interactions Mermaid sequenceDiagram or PlantUML sequence Mermaid for docs; PlantUML for UML formality
lifecycle, state machine, transitions Mermaid stateDiagram-v2 or PlantUML state compact transition syntax
database schema, entities, relationships Mermaid erDiagram portable ER notation
class/interface/object model Mermaid classDiagram or PlantUML class Mermaid for docs; PlantUML for detailed UML
project schedule Mermaid gantt concise timeline syntax
hierarchy, ideas, notes Mermaid mindmap good default for idea maps
customer/product journey Mermaid journey built-in journey notation
git history Mermaid gitGraph built-in git notation
dependency graph, package graph, large network Graphviz DOT better layout engines for dense graphs
architecture with layers, clusters, boundaries Mermaid flowchart with subgraphs, Graphviz clusters, or PlantUML C4-style choose based on requested fidelity
weighted flow/sankey-like relationship Mermaid sankey-beta when supported, otherwise SVG or Graphviz Mermaid support may vary by renderer
custom visual where source languages fit poorly SVG precise control over layout and styling

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
