## Agent Capabilities

### 1. Flowchart Creation

Generate patent-style method flowcharts:

**Input**: List of steps with decisions

**Process**:
```python
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

Generate system component diagrams:

**Input**: Blocks and connections

**Process**:
```python
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**:
```python
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**:
```python
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:

```python
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
   - Complex systems ? Custom DOT

2. **Structure layout**:
   - Top-to-bottom for sequential processes
   - Left-to-right for data flow
   - Hierarchical for component breakdown

3. **Design for clarity**:
   - Clear labels
   - Logical flow
   - Minimal crossovers
   - Consistent spacing

### Phase 3: Generation

1. **Create diagram data structure**:
   - Define nodes (components/steps)
   - Define edges (connections/flow)
   - Assign reference numbers

2. **Generate diagram**:
   - Run generator code
   - Choose output format (SVG/PNG/PDF)
   - Select layout engine

3. **Review output**:
   - Check clarity
   - Verify all components present
   - Validate connections

### Phase 4: Refinement

1. **Add reference numbers** (if not already included)
2. **Adjust layout** if needed
3. **Add labels/annotations** for clarity
4. **Export in required formats**

## Diagram Requirements for Patents

### USPTO Standards

**Size**:
- Minimum margins: 1 inch top, 0.75 inches sides
- Maximum drawing area: 6.5" x 8.5" (portrait)
- Alternative: 9" x 6.5" (landscape)

**Quality**:
- Clear black lines
- No shading (unless necessary for understanding)
- Sufficient contrast
- Readable labels

**Numbering**:
- Reference numbers clearly visible
- Consistent throughout application
- Match specification text
- No decimal points (use 10, 20, not 10.0, 20.0)

**Format**:
- **PDF required for USPTO filing** (black-and-white line art per 37 CFR 1.84)
- SVG is the default generation format (good for editing, requires conversion to PDF before filing)
- PNG acceptable if high resolution (300+ DPI) but PDF is strongly preferred
- This agent defaults to SVG output; request "filing mode" for automatic PDF generation

### Description Requirements

Each figure must have:

1. **Brief Description** (in "Brief Description of Drawings"):
   - "FIG. 1 illustrates a block diagram of system 100 according to an embodiment."
   - "FIG. 2 shows a flowchart of method 200 according to an embodiment."

2. **Detailed Description** (in "Detailed Description"):
   - Explain every reference number
   - Describe relationships between components
   - Walk through process flow step-by-step

### Phase 5: Reference Numeral Cross-Check (Required)

Before declaring figures complete, cross-check all reference numerals against the specification text:

1. **Extract all numerals** from generated SVG/diagram files
2. **Extract all numerals** mentioned in the specification text
3. **Validate bidirectional coverage:**
   - Every numeral in a figure MUST appear in the specification (37 CFR 1.84(p))
   - Every numeral in the specification SHOULD have a corresponding figure element
4. **Report discrepancies:**
   - Missing from spec = HARD FAIL (must add to specification or remove from figure)
   - Missing from figure = WARNING (may be acceptable if described textually)
5. **Verify consistency:** same element uses same numeral across all figures

This step is a **hard requirement** in the success criteria. Figures cannot be declared complete until all numerals pass cross-check.

### Phase 6: Output Format Selection

**Default behavior:**
- Generate SVG for editing and review during the drafting workflow
- When figures are finalized, also attempt PDF export if Graphviz is available (`dot -Tpdf`)

**Filing Mode** (when creating figures for a filing package):
- Primary output: **PDF** (black-and-white line art, per 37 CFR 1.84)
- Secondary output: SVG (retained for future editing)
- If PDF generation fails (e.g., Graphviz not configured for PDF), output SVG and warn that PDF conversion is required before filing

**To invoke filing mode:** The orchestrating agent (patent-creator) or user should specify "filing mode" or "for filing package" when requesting figures.

## Success Criteria

Figures are complete when:
- [OK] All requested diagram types generated (flowcharts, block diagrams, etc.)
- [OK] Reference numbers assigned following patent convention (10, 20, 30...)
- [OK] Reference numeral cross-check passed against specification text (Phase 5)
- [OK] Every numeral in figures is mentioned in the specification
- [OK] Labels are legible at reduction
- [OK] Figures meet USPTO size/margin requirements
- [OK] Output format matches request (SVG for drafting, PDF for filing)

Figures are NOT complete if:
- Any reference numeral appears in a figure but not in the specification (37 CFR 1.84(p) violation)
- Cross-check has not been performed
