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 — always load references/style-1-flat-icon.md 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 python3 -c "import xml.etree.ElementTree as ET; ET.parse('file.svg')" to check XML syntax
9. Export PNG: Use cairosvg (recommended). See SVG → PNG Conversion section below for full method comparison
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
    • Move arrow labels 6-8px away from the arrow line (offset-first); add background rects only when offset is insufficient
    • 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
    • If a filtered element (drop-shadow, blur) is missing one side of its border, move it ≥30px away from that viewBox edge, or remove the filter and rely on color/contrast for visual separation 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)

  • Aggregation: solid line + hollow diamond on container side
  • Composition: solid line + filled diamond on container side
  • Dependency: dashed line + open arrowhead

  • Label below figure, 13-14px
  • Primary actors on left, secondary/supporting on right
• Use case: ellipse with label centered inside, min 140×60px

Shape Vocabulary

Map semantic concepts to consistent shapes across all diagram types:

Arrow Semantics

Always assign arrow meaning, not just color:

Always include a legend when 2+ arrow types are used.

Layout Rules & Validation

Spacing:

• Same-layer nodes: 80px horizontal, 120px vertical between layers
• Canvas margins: 40px minimum, 60px between node edges
• Snap to 8px grid: horizontal 120px intervals, vertical 120px intervals

Arrow Labels (CRITICAL):

• Offset-first (default): place label 6-8px above horizontal arrows, or 8px left/right of vertical arrows — do not overlap the arrow line
• Background fallback: add <rect fill="canvas_bg" opacity="0.95"/> only when the offset label still crosses another visual element (another arrow, a node edge, etc.)
• Place mid-arrow, ≤3 words, stagger by 15-20px when multiple arrows converge
• Maintain 10px safety distance from nodes

Arrow Routing:

• Prefer orthogonal (L-shaped) paths to minimize crossings
• Anchor arrows on component edges, not geometric centers
• Route around dense node clusters, use different y-offsets for parallel arrows
• Jump-over arcs (5px radius) for unavoidable crossings

Post-Generation Arrow Optimization:

When a user asks to "优化箭头" / "fix arrow routing" / "optimize the diagram" on an already-generated diagram, preserve all nodes, containers, styles, and layout — only modify the arrows entries in the JSON data, then re-render with generate-from-template.py.

Available arrow override fields (in recommended order of use):

For JSON/template rendering, the default remains "badge" for backward compatibility. Set "label_style": "offset" on individual arrows when you want offset-first labels without background rects.

Optimization steps:

1. Read the existing SVG — identify which arrows overlap, cross nodes, or look misaligned
2. Find those arrows in the JSON data by source / target pair
3. Add source_port / target_port if the exit/entry direction is wrong; add corridor_x / corridor_y to space parallel arrows apart; use route_points only when hints alone cannot resolve the path
4. Re-run generate-from-template.py with the updated JSON and validate with validate-svg.sh

Example — spacing two overlapping arrows into separate corridors:

{ "source": "nodeA", "target": "nodeB", "corridor_y": [280] }
{ "source": "nodeC", "target": "nodeD", "corridor_y": [320] }

Line Overlap Prevention (CRITICAL - most common bug on Codex): When two arrows must cross each other, ALWAYS use jump-over arcs to prevent visual overlap:

• Crossing horizontal arrows: add a small semicircle arc (radius 5px, stroke same color as arrow, fill none) that "jumps over" the other line
• SVG pattern for jump-over: use a white/matching-background arc on the lower layer, then draw the upper arc on top
• Multiple crossings: stagger arc radii (5px, 7px, 9px) so arcs don't overlap each other
• Never let two arrows' straight-line segments cross without a jump-over arc

Validation Checklist (run before finalizing):

1. Arrow-Component Collision: Arrows MUST NOT pass through component interiors (route around with orthogonal paths)
2. Text Overflow: All text MUST fit with 8px padding (estimate: text.length × 7px ≤ shape_width - 16px)
3. Arrow-Text Alignment: Arrow endpoints MUST connect to shape edges (not floating); arrow labels should not overlap arrow lines (use offset positioning or background rects)
4. Container Discipline: Prefer arrows entering and leaving section containers through open gaps between components, not through inner component bodies
5. Filter Boundary Safety: For every element with filter="url(...)", verify (element_x + element_width + filter_extension) ≤ viewBox_width AND element_x ≥ filter_extension. The default filter region extends 10-20% beyond bbox; staying near viewBox edges causes Chrome/cairosvg to clip the element's edge-side stroke (one side of the border vanishes while other sides render correctly)
6. Arrow-Title Collision: Arrows MUST NOT cross through section/container title text or region labels (font-size ≥ 13px). For smaller annotations (< 13px), prefer routing around but tolerate if layout constraints require it. (Visual self-review check — not covered by validate-svg.sh automated checks)
7. Frame Label–Arrow Alignment (sequence diagrams): Section/frame label badges MUST be vertically centered with their first message arrow. Compute badge_y = first_arrow_y - (badge_height / 2). When appending new sections to an existing diagram, verify alignment matches the existing sections — this is the most common regression when adding content incrementally. Use variables in Python list generation to enforce the constraint: sec_y = 840; badge_y = sec_y - 9 # for height=18 badge

SVG Technical Rules

• ViewBox: 0 0 960 600 default; 0 0 960 800 tall; 0 0 1200 600 wide
• Fonts: embed via <style>font-family: ...</style> — no external @import (cairosvg / rsvg-convert cannot fetch external URLs)
• <defs>: arrow markers, gradients, filters, clip paths
• Text: minimum 12px, prefer 13-14px labels, 11px sub-labels, 16-18px titles
• All arrows: <marker> with markerEnd, sized markerWidth="10" markerHeight="7"
• Drop shadows: <feDropShadow> in <filter>, apply sparingly (key nodes only)
• Curved paths: use M x1,y1 C cx1,cy1 cx2,cy2 x2,y2 cubic bezier for loops/feedback arrows
• Clip content: use <clipPath> if text might overflow a node box
• Z-order (drawing order): SVG uses painter's model — later elements cover earlier ones. Recommended layer order (bottom → top): ① canvas background ② dashed containers / region backgrounds ③ arrows and connection lines ④ node shapes (rects, circles) ⑤ text labels and annotations ⑥ legends and overlays. When arrows pass near text, draw arrows BEFORE text so text stays readable. Adjust per diagram needs — this is guidance, not rigid.

SVG Generation & Error Prevention

MANDATORY: Python List Method (ALWAYS use this):

python3 << 'EOF'
lines = []
lines.append('<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 960 700">')
lines.append('  <defs>')
# ... each line separately
lines.append('</svg>')

with open('/path/to/output.svg', 'w') as f:
    f.write('\n'.join(lines))
print("SVG generated successfully")
EOF

Why mandatory: Prevents character truncation, typos, and syntax errors. Each line is independent and easy to verify.

Pre-Tool-Call Checklist (CRITICAL - use EVERY time):

1. ✅ Can I write out the COMPLETE command/content right now?
2. ✅ Do I have ALL required parameters ready?
3. ✅ Have I checked for syntax errors in my prepared content?

If ANY answer is NO: STOP. Do NOT call the tool. Prepare the content first.

Error Recovery Protocol:

• First error: Analyze root cause, apply targeted fix
• Second error: Switch method entirely (Python list → chunked generation)
• Third error: STOP and report to user - do NOT loop endlessly
• Never: Retry the same failing command or call tools with empty parameters

Validation (run after generation):

python3 -c "import xml.etree.ElementTree as ET; ET.parse('file.svg')" && echo "✓ Valid XML"
# Or use cairosvg as a render-time check:
python3 -c "import cairosvg; cairosvg.svg2png(url='file.svg', write_to='/tmp/test.png')" && echo "✓ Renders" && rm /tmp/test.png

If using generate-from-template.py:

• Prefer source / target node ids in arrow JSON so the generator can snap to node edges
• Keep x1,y1,x2,y2 as hints or fallback coordinates, not the main routing primitive
• Let the generator choose orthogonal routes; avoid hardcoding center-to-center straight lines unless the path is guaranteed clear

Common Syntax Errors to Avoid:

• ❌ yt-anchor → ✅ y="60" text-anchor="middle"
• ❌ x="390 (missing y) → ✅ x="390" y="250"
• ❌ fill=#fff → ✅ fill="#ffffff"
• ❌ marker-end= → ✅ marker-end="url(#arrow)"
• ❌ L 29450 → ✅ L 290,220
• ❌ Missing </svg> at end
• ❌ Element with filter near viewBox edge — filter region extends 20% (default) or more beyond bbox; if that region exceeds viewBox, Chrome/cairosvg clip the filter rendering AND can drop the element's own stroke on that side. Keep filtered elements at least max(20% of element size, shadow blur radius × 3) away from viewBox edges, or omit the filter.

Output

• Default: ./[derived-name].svg and ./[derived-name].png in current directory
• Custom: user specifies path with --output /path/ or 输出到 /path/
• PNG export: see SVG → PNG Conversion below

SVG → PNG Conversion

Method Comparison

Recommended: cairosvg (Python one-liner)

# Single file (2x resolution for retina/docs)
python3 -c "import cairosvg; cairosvg.svg2png(url='input.svg', write_to='output.png', scale=2)"

# Batch convert all SVGs in a directory
python3 -c "
import cairosvg, os, glob
d = 'docs/00-core'
for svg in sorted(glob.glob(os.path.join(d, '*.svg'))):
    png = svg.replace('.svg', '.png')
    cairosvg.svg2png(url=svg, write_to=png, scale=2)
    print(f'Done: {os.path.basename(svg)} -> {os.path.basename(png)}')
"

scale=2 produces 2x resolution PNG, ideal for high-DPI screens and embedded docs.

Fallback: rsvg-convert (simple but may drop styles)

# Single file
rsvg-convert -w 1920 file.svg -o file.png

# Batch (not recommended — complex SVGs may lose elements)
for f in docs/00-core/*.svg; do rsvg-convert -o "${f%.svg}.png" "$f"; done

# 2x resolution
for f in docs/00-core/*.svg; do rsvg-convert -z 2 -o "${f%.svg}.png" "$f"; done

Highest Fidelity: puppeteer (headless Chrome)

npm install puppeteer  # auto-downloads Chromium
node svg2png.js [directory]

const puppeteer = require('puppeteer');
const fs = require('fs');
const path = require('path');

(async () => {
  const dir = process.argv[2] || '.';
  const svgFiles = fs.readdirSync(dir).filter(f => f.endsWith('.svg'));

  const browser = await puppeteer.launch({
    headless: 'new',
    args: ['--no-sandbox', '--disable-setuid-sandbox']
  });

  for (const file of svgFiles) {
    const svgPath = path.resolve(dir, file);
    const pngPath = svgPath.replace(/\.svg$/, '.png');
    const svgContent = fs.readFileSync(svgPath, 'utf-8');

    const wMatch = svgContent.match(/width="(\d+)/);
    const hMatch = svgContent.match(/height="(\d+)/);
    const vbMatch = svgContent.match(/viewBox="[^"]*\s(\d+)\s(\d+)"/);

    let width = wMatch ? parseInt(wMatch[1]) : (vbMatch ? parseInt(vbMatch[1]) : 1200);
    let height = hMatch ? parseInt(hMatch[1]) : (vbMatch ? parseInt(vbMatch[2]) : 800);

    const scale = 2;
    const page = await browser.newPage();
    await page.setViewport({ width, height, deviceScaleFactor: scale });

    const html = `<!DOCTYPE html>
<html><head><style>
  body { margin: 0; padding: 0; background: transparent; }
  img { display: block; }
</style></head>
<body>
  <img src="data:image/svg+xml;base64,${Buffer.from(svgContent).toString('base64')}" width="${width}" height="${height}" />
</body></html>`;

    await page.setContent(html, { waitUntil: 'networkidle0' });
    await page.screenshot({ path: pngPath, type: 'png', omitBackground: true });
    await page.close();

    console.log(`Done: ${file} -> ${path.basename(pngPath)} (${width}x${height} @${scale}x)`);
  }

  await browser.close();
})();

Gotchas (lessons learned)

• rsvg-convert renders SVGs containing <foreignObject>, CSS filter, or complex <style> blocks incompletely — missing borders / missing text are the typical symptoms
• cairosvg (built on Cairo) has much better CSS support than rsvg and is sufficient for most cases
• cairosvg may fail to render CJK characters and emoji in <text> elements — Cairo's font API (cairo_select_font_face) does not reliably perform system fontconfig fallback, so glyphs not present in the matched font face render as □ (empty box). This commonly affects Chinese/Japanese/Korean text and emoji, depending on system font configuration. Workaround: use SVG as primary format for web/GitHub rendering (browsers handle CJK natively); reserve PNG export for Latin-only diagrams, or switch to the puppeteer path for full CJK+emoji fidelity
• If the SVG was generated by a browser (D3.js, Mermaid, etc.), only headless Chrome (puppeteer) renders it 100% faithfully
• Chrome headless CLI --window-size=W,H is not the drawable area — even in --headless=new mode, browser chrome (scrollbars, internal UI surfaces) consumes ~15-20% of both width and height, so the actual SVG viewport is only ~0.84×W by ~0.84×H. Symptom: SVG content past x ≈ 0.84 × W or y ≈ 0.84 × H is cut off and renders as a solid white band, even though the SVG file itself is correct. Typical failure modes: a Legend in the top-right corner loses its right border; a bottom-row container loses its bottom dashed line. Fix: pass window dimensions ≥ SVG width × 1.2 AND SVG height × 1.2, then crop the raw screenshot back to (SVG_width × scale, SVG_height × scale) with PIL or ImageMagick. Example: for a 1280×580 SVG at 3× DPR, use --window-size=1600,800 then crop the output to 3840×1740. The Puppeteer / page.setViewport() path does NOT have this issue — it sets a precise viewport regardless of window UI.

Picking a Method

1. Default → cairosvg (pip install once, one-line conversion, good fidelity)
2. No Python available → rsvg-convert (acceptable for simple flat-color diagrams)
3. Browser-generated SVG or pixel-perfect required → puppeteer

Styles

Load references/style-N.md for exact color tokens and SVG patterns.

Style Selection

Default: Style 1 (Flat Icon) for most diagrams. Load references/style-diagram-matrix.md for detailed style-to-diagram-type recommendations.

These patterns appear frequently — internalize them:

RAG Pipeline: Query → Embed → VectorSearch → Retrieve → Augment → LLM → Response Agentic RAG: adds Agent loop with Tool use between Query and LLM Agentic Search: Query → Planner → [Search Tool / Calculator / Code] → Synthesizer → Response Mem0 / Memory Layer: Input → Memory Manager → [Write: VectorDB + GraphDB] / [Read: Retrieve+Rank] → Context Agent Memory Types: Sensory (raw input) → Working (context window) → Episodic (past interactions) → Semantic (facts) → Procedural (skills) Multi-Agent: Orchestrator → [SubAgent A / SubAgent B / SubAgent C] → Aggregator → Output Tool Call Flow: LLM → Tool Selector → Tool Execution → Result Parser → LLM (loop)
