# Fireworks Tech Graph
Generate production-quality SVG technical diagrams exported as PNG via `rsvg-convert`.
## Install Source
Install this skill from GitHub:
```bash
npx skills add yizhiyanhua-ai/fireworks-tech-graph
```
Public package page:
```text
https://www.npmjs.com/package/@yizhiyanhua-ai/fireworks-tech-graph
```
Do not pass `@yizhiyanhua-ai/fireworks-tech-graph` directly to `skills add`, because the CLI expects a GitHub or local repository source.
Update command:
```bash
npx skills add yizhiyanhua-ai/fireworks-tech-graph --force -g -y
```
## Helper Scripts (Recommended)
Four helper scripts in `scripts/` directory provide stable SVG generation and validation:
### 1. `generate-diagram.sh` - Validate SVG + export PNG
```bash
./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
```bash
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
```bash
./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
```bash
./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 `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
## 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)

| Embedding / transform | purple `#7c3aed` | 1px solid | none | Data transformation |
| Feedback / loop | purple `#7c3aed` | 1.5px curved | none | Iterative reasoning loop |
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):
- MUST have background rect: `<rect fill="canvas_bg" opacity="0.95"/>` with 4px horizontal, 2px vertical padding
- 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
**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)
