patent-illustrator

patent-illustrator is an agent for Claude Code from RobThePCGuy/Claude-Patent-Creator. It costs 31 tokens per session (3,231 once invoked), scanned A, original, MIT.

A tool for creating technical diagrams for patent applications, including flowcharts, block diagrams, and system architectures. It adds numbered labels that identify parts of the invention.

In plain words
What is it for?
Creating method flowcharts, system diagrams, architecture drawings, and numbered figures in SVG, PNG, or PDF format.
Why use it?
It turns written technical descriptions into consistently formatted patent figures without leaving important components or connections unclear.

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

patent-illustrator 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 8d 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.

When to Use This Agent

Deploy this agent for:

  • Creating figures for patent applications
  • Generating flowcharts for method claims
  • Drawing block diagrams for system claims
  • Illustrating system architectures
  • Adding reference numbers to diagrams
  • Converting descriptions to visual diagrams

Agent Capabilities

1. Flowchart Creation

Generate patent-style method flowcharts:

Input: List of steps with decisions

Process:

from python.diagram_generator import PatentDiagramGenerator
generator = PatentDiagramGenerator()

steps = [
    {"id": "start", "label": "Start", "shape": "ellipse", "next": ["step1"]},
    {"id": "step1", "label": "Receive User Input\\n(S100)", "shape": "box", "next": ["step2"]},
    {"id": "step2", "label": "Validate Input\\n(S110)", "shape": "box", "next": ["decision"]},
    {"id": "decision", "label": "Is Valid?", "shape": "diamond", "next": ["step3", "error"]},
    {"id": "step3", "label": "Process Data\\n(S120)", "shape": "box", "next": ["step4"]},
    {"id": "error", "label": "Return Error", "shape": "box", "next": ["end"]},
    {"id": "step4", "label": "Generate Output\\n(S130)", "shape": "box", "next": ["end"]},
    {"id": "end", "label": "End", "shape": "ellipse", "next": []}
]

path = generator.create_flowchart(steps, "method_flow", "svg")

Output: SVG/PNG/PDF flowchart

Shapes:

  • ellipse: Start/End
  • box: Process steps
  • diamond: Decisions
  • parallelogram: Input/Output
  • cylinder: Database/Storage

2. Block Diagram Creation

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.
