Agent Capabilities

1. Flowchart Creation

Generate patent-style method flowcharts:

**Input**: List of steps with decisions

**Process**:

from mcp_server.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

Generate system component diagrams:

**Input**: Blocks and connections

**Process**:

blocks = [
    {"id": "sensor", "label": "Input Sensor\\n(10)", "type": "input"},
    {"id": "processor", "label": "Central Processor\\n(20)", "type": "process"},
    {"id": "memory", "label": "Memory Module\\n(30)", "type": "storage"},
    {"id": "display", "label": "Output Display\\n(40)", "type": "output"}
]

connections = [
    ["sensor", "processor", "raw data"],
    ["processor", "memory", "store"],
    ["memory", "processor", "retrieve"],
    ["processor", "display", "processed output"]
]

path = generator.create_block_diagram(blocks, connections, "system_arch", "svg")

**Output**: SVG/PNG/PDF block diagram

**Block Types**:

• `input`: Input devices (sensors, interfaces)
• `output`: Output devices (displays, actuators)
• `process`: Processing units (CPUs, controllers)
• `storage`: Memory/storage devices
• `decision`: Control logic
• `default`: General components

3. Custom DOT Rendering

For complex or custom diagrams:

**Input**: Graphviz DOT code

**Process**:

dot_code = """
digraph PatentSystem {
    rankdir=LR;  // Left-to-right layout
    node [shape=box, style="rounded,filled", fillcolor=lightblue];
    edge [fontsize=10];

    // Components with reference numbers
    User [label="User\\n(10)", shape=ellipse];
    Input [label="Input Interface\\n(12)"];
    Auth [label="Authentication\\nModule\\n(20)"];
    DB [label="Database\\n(30)", shape=cylinder];
    Process [label="Processing Unit\\n(40)"];
    Output [label="Output Display\\n(50)"];

    // Data flow connections
    User -> Input [label="input data"];
    Input -> Auth [label="credentials"];
    Auth -> DB [label="verify"];
    DB -> Auth [label="result"];
    Auth -> Process [label="authorized data"];
    Process -> Output [label="processed result"];
    Output -> User [label="display"];
}
"""

path = generator.render_dot_diagram(
    dot_code=dot_code,
    filename="custom_system",
    output_format="svg",
    engine="dot"
)

**Output**: Rendered custom diagram

**Layout Engines**:

• `dot`: Hierarchical (directed graphs)
• `neato`: Spring model (undirected graphs)
• `fdp`: Force-directed (large graphs)
• `circo`: Circular layout
• `twopi`: Radial layout

4. Reference Number Annotation

Add patent-style reference numbers to existing diagrams:

**Process**:

reference_map = {
    "Input Sensor": 10,
    "Central Processor": 20,
    "Memory Module": 30,
    "Output Display": 40,
    "Communication Interface": 50
}

annotated_path = generator.add_reference_numbers(
    svg_path="system_diagram.svg",
    reference_map=reference_map
)

**Output**: Annotated SVG with reference numbers

**Numbering Convention**:

• **Major components**: 10, 20, 30, 40, 50...
• **Sub-components**: 12, 14, 16, 18 (under 10)
• **Elements**: 22, 24, 26, 28 (under 20)
• **Parts**: 32, 34, 36, 38 (under 30)

5. Diagram Templates

Pre-built templates for common patent diagrams:

templates = generator.get_diagram_templates()

# Available templates:
# - simple_flowchart: Basic process flow with start/end
# - system_block: System architecture with components
# - method_steps: Sequential method steps with numbering
# - component_hierarchy: Hierarchical component structure

Working Process

Phase 1: Requirement Gathering

1. **Interview user** about what needs to be illustrated 2. **Identify diagram type** (flowchart, block, system, custom) 3. **List components** or steps to include 4. **Define connections** and relationships 5. **Plan reference numbering** scheme

Phase 2: Diagram Design

1. **Choose appropriate diagram type**:

• Method claims ? Flowchart
• System claims ? Block diagram
• Comp
