Helper Scripts (Recommended)

Four helper scripts in scripts/ directory provide stable SVG generation and validation:

1. generate-diagram.sh - Validate SVG + export PNG

./scripts/generate-diagram.sh -t architecture -s 1 -o ./output/arch.svg

• Validates an existing SVG file
• Exports PNG after validation
• Example: ./scripts/generate-diagram.sh -t architecture -s 1 -o ./output/arch.svg

2. generate-from-template.py - Create starter SVG from template

python3 ./scripts/generate-from-template.py architecture ./output/arch.svg '{"title":"My Diagram","nodes":[],"arrows":[]}'

• Loads a built-in SVG template
• Renders nodes, arrows, and legend entries from JSON input
• Escapes text content to keep output XML-valid

3. validate-svg.sh - Validate SVG syntax

./scripts/validate-svg.sh <svg-file>

• Checks XML syntax
• Verifies tag balance
• Validates marker references
• Checks attribute completeness
• Validates path data

4. test-all-styles.sh - Batch test all styles

./scripts/test-all-styles.sh

• Tests multiple diagram sizes
• Validates all generated SVGs
• Generates test report

When to use scripts:

• Use scripts when generating complex SVGs to avoid syntax errors
• Scripts provide automatic validation and error reporting
• Recommended for production diagrams

When to generate SVG directly:

• Simple diagrams with few elements
• Quick prototypes
• When you need full control over SVG structure

Workflow (Always Follow This Order)

1. Classify the diagram type (see Diagram Types below)
2. Extract structure — identify layers, nodes, edges, flows, and semantic groups from user description
3. Plan layout — apply the layout rules for the diagram type
4. Load style reference — load references/style-1-flat-icon.md as the default only after this skill is selected, unless user specifies another; load the matching references/style-N.md for exact color tokens and SVG patterns
5. Map nodes to shapes — use Shape Vocabulary below
6. Check icon needs — load references/icons.md for known products
7. Write SVG with adaptive strategy (see SVG Generation Strategy below)
8. Validate: Run rsvg-convert file.svg -o /dev/null 2>&1 to check syntax
9. Export PNG: rsvg-convert -w 1920 file.svg -o file.png
10. Report the generated file paths
11. (Optional) Visual self-review — if your runtime can read images, load the exported PNG back and inspect it. Syntactic validity does not guarantee visual correctness: arrows may cross through component interiors, labels may collide with lifelines or other labels, boxes may overlap, alt-frame text may sit on top of a message, or a legend may cover content. If you see any of these, revise the SVG and re-export; repeat until the rendered image is clean. Common fixes:
    • Route arrows through gaps between boxes, not through box interiors
    • Add background rects behind arrow labels (opacity 0.95, matching canvas color)
    • Widen inter-row/inter-column gutters so same-layer arrows have clear corridors
    • Collapse repeated cross-layer arrows into a single "delegates down" rail outside the content area
    • Move legend/notes out of any region where arrows or labels land
    • Increase viewBox height/width rather than packing elements tighter Skip this step silently if image reading is unavailable — do not guess.

Diagram Types & Layout Rules

Architecture Diagram

Nodes = services/components. Group into horizontal layers (top→bottom or left→right).

• Typical layers: Client → Gateway/LB → Services → Data/Storage
• Use <rect> dashed containers to group related services in the same layer
• Arrow direction follows data/request flow
• ViewBox: 0 0 960 600 standard, 0 0 960 800 for tall stacks

Data Flow Diagram

Emphasizes what data moves where. Focus on data transformation.

• Label every arrow with the data type (e.g., "embeddings", "query", "context")
• Use wider arrows (stroke-width: 2.5) for primary data paths
• Dashed arrows for control/trigger flows
• Color arrows by data category (not just Agent/RAG — use semantics)

Flowchart / Process Flow

Sequential decision/process steps.

• Top-to-bottom preferred; left-to-right for wide flows
• Diamond shapes for decisions, rounded rects for processes, parallelograms for I/O
• Keep node labels short (≤3 words); put detail in sub-labels
• Align nodes on a grid: x positions snap to 120px intervals, y to 80px

Agent Architecture Diagram

Shows how an AI agent reasons, uses tools, and manages memory. Key conceptual layers to always consider:

• Input layer: User, query, trigger
• Agent core: LLM, reasoning loop, planner
• Memory layer: Short-term (context window), Long-term (vector/graph DB), Episodic
• Tool layer: Tool calls, APIs, search, code execution
• Output layer: Response, action, side-effects Use cyclic arrows (loop arcs) to show iterative reasoning. Separate memory types visually.

Memory Architecture Diagram (Mem0, MemGPT-style)

Specialized agent diagram focused on memory operations.

• Show memory write path and read path separately (different arrow colors)
• Memory tiers: Working Memory → Short-term → Long-term → External Store
• Label memory operations: store(), retrieve(), forget(), consolidate()
• Use stacked rects or layered cylinders for storage tiers

Sequence Diagram

Time-ordered message exchanges between participants.

• Participants as vertical lifelines (top labels + vertical dashed lines)
• Messages as horizontal arrows between lifelines, top-to-bottom time order
• Activation boxes (thin filled rects on lifeline) show active processing
• Group with <rect> loop/alt frames with label in top-left corner
• ViewBox height = 80 + (num_messages × 50)

Comparison / Feature Matrix

Side-by-side comparison of approaches, systems, or components.

• Column headers = systems, row headers = attributes
• Row height: 40px; column width: min 120px; header row height: 50px
• Checked cell: tinted background (e.g. #dcfce7) + ✓ checkmark; unsupported: #f9fafb fill
• Alternating row fills (#f9fafb / #ffffff) for readability
• Max readable columns: 5; beyond that, split into two diagrams

Timeline / Gantt

Horizontal time axis showing durations, phases, and milestones.

• X-axis = time (weeks/months/quarters); Y-axis = items/tasks/phases
• Bars: rounded rects, colored by category, labeled inside or beside
• Milestone markers: diamond or filled circle at specific x position with label above
• ViewBox: 0 0 960 400 typical; wider for many time periods: 0 0 1200 400

Mind Map / Concept Map

Radial layout from central concept.

• Central node at cx=480, cy=280
• First-level branches: evenly distributed around center (360/N degrees)
• Second-level branches: branch off first-level at 30-45° offset
• Use curved <path> with cubic bezier for branches, not straight lines

Class Diagram (UML)

  • Label below figure, 13-14px
  • Primary actors on left, secondary/supporting on right
• Use case: ellipse with label centered inside, min 140×60px
  • Keep names verb phrases: "Create Order", "Process Payment"
• System boundary: large rect with dashed border + system name in top-left
• Relationships:
  • Include: dashed arrow <<include>> from base to included use case
  • Extend: dashed arrow <<extend>> from extension to base use case
  • Generalization: solid line + hollow triangle (specialized → general)
• Layout: system boundary centered, actors outside, use cases inside
• ViewBox: 0 0 960 600 standard
