## Overview

`fireworks-tech-graph` is one Agent Skill that works unchanged in **Codex and Claude Code**. It turns natural language descriptions into polished, geometry-checked SVG diagrams, high-resolution PNGs, validated SVG-to-GIF semantic motion, and offline interactive HTML. The focused animation path accepts a generated semantic SVG and emits one compact, probed GIF. It ships with **11 generator-backed styles** and **1 AI-authored style (Dark Luxury)**. Four engineering-first styles add executable contracts for C4 reviews, cloud deployments, event streams, and reliability investigations, alongside deep AI/Agent domain patterns and all 14 UML diagram types.

```
User: "Generate a Mem0 memory architecture diagram, dark style"
  → Skill classifies: Memory Architecture Diagram, Style 2
  → Generates SVG with swim lanes, cylinders, semantic arrows
  → Exports 1920px PNG
  → Reports: mem0-architecture.svg / mem0-architecture.png
```

---

## Work With the Builder

This project is also a proof surface for a broader capability: turning vague AI/devtool workflows into constrained, reusable systems with validation, documentation, export paths, and product-facing polish.

If you are building agent infrastructure, AI IDEs, internal copilots, developer tools, technical documentation systems, or applied AI workflow products, I am open to scoped paid sprints, design-partner work, and founding engineer conversations.

## Showcase

> The animated previews use the user-approved 5.75-second settled-flow timeline: routes draw in first, then the final topology keeps live data moving for two additional seconds. Each full-size GIF is 960px wide at 20fps / 115 frames; the 3×4 overview is an optimized 1200px preview. Lossless 1920px PNGs remain in `assets/samples/` as static regression baselines.

![Animated 12-style showcase — one distinct engineering scenario per style](https://raw.githubusercontent.com/yizhiyanhua-ai/fireworks-tech-graph/main/assets/samples/showcase-12-styles.gif)

The v1.2.0 overview above and every full-size animated sample below come from the approved regression set. Each style keeps a distinct scenario while sharing the same geometry, text-fit, wire-routing, and semantic-motion quality gates.

## Stable Prompt Recipe

The public showcase keeps a distinct domain scene for every style. They remain comparable because every fixture passes the same executable composition contract. A same-topology regression set remains internal under `fixtures/quality-baseline/`.

```text
Draw the scenario assigned to style N:
1 Mem0 Memory Architecture; 2 Tool Call Flow; 3 Microservices Architecture;
4 Agent Memory Types; 5 Multi-Agent Collaboration; 6 System Architecture;
7 API Integration Flow; 8 Agent Runtime Architecture; 9 C4 Checkout Review;
10 Active–Active Cloud Deployment; 11 Checkout Event Line; 12 Checkout Reliability Pulse.
Preserve the scenario-specific nodes, sections, and reading direction.
Apply the showcase composition contract: zero crossings, zero bridge jumps, at most two bends per edge,
at most eight bends overall, at least 40px between nodes, at least 20px container gutter,
short orthogonal segments, and labels kept clear of nodes, routes, and section headers.
Preserve the selected style's typography, palette, card material, and brand details.
```

For the four engineering-first styles, use one of these prompt fingerprints so
the router selects the domain contract as well as the visual theme:

```text
Style 9 · C4 review board: show one C4 level, responsibilities, technologies, review state, and relationship protocols.
Style 10 · Multi-region deployment map: show global ingress, Region/VPC ownership, neutral cloud glyphs, deployment mode, and named boundary mechanisms.
Style 11 · Event metro map: show thin topic rails, numbered processor stations, declared junctions, consumer groups, DLQ, and state projections.
Style 12 · Reliability pulse: show one observation window, four golden signals per service, numbered critical hops, telemetry export, and one correlated trace.
```

Replace `N` with `1`–`12`. Style 8 remains AI-authored and loads `references/style-8-dark-luxury.md`; Styles 9–12 also enforce their engineering semantic contract. All styles load `references/composition-quality-contract.md`.

---

## Features

- **12 visual styles** — 11 generator-backed profiles + 1 AI-authored style (Dark Luxury)
- **Engineering semantic contracts** — C4 abstraction levels, deployment ownership, event-rail topology, and exact golden signals fail closed before rendering
- **Executable style system** — style guides are encoded into the generator, not only documented in markdown
- **Shared composition-quality contract** — every official style enforces zero crossings/bridges, ≤2 bends per edge, route-stretch, spacing, gutter, micro-segment, and label-clearance budgets
- **14 diagram types** — Full UML support (Class, Component, Deployment, Package, Composite Structure, Object, Use Case, Activity, State Machine, Sequence, Communication, Timing, Interaction Overview, ER Diagram) plus AI/Agent domain diagrams
- **AI/Agent domain patterns** — RAG, Agentic Search, Mem0, Multi-Agent, Tool Call, and more built-in
- **Semantic shape vocabulary** — LLM = double-border rect, Agent = hexagon, Vector Store = ringed cylinder
- **Semantic arrow system** — color + dash pattern encode meaning (write vs read vs async vs loop)
- **Geometry-safe routing** — deterministic orthogonal routes, exact waypoints, distinct ports, automatic legend relocation, labels kept inside the canvas, and verified bridge jumps for unavoidable crossings
- **Versioned diagram IR** — legacy JSON normalizes to schema v1; duplicate IDs, dangling references, malformed waypoints, and non-finite geometry fail before rendering
- **Structured SVG validation** — XML and marker integrity plus semantic node, reserved-region, label, canvas, edge-overlap, and edge-crossing checks
- **Unified CLI + interactive export** — render, validate, inspect, and export one offline HTML file with pan/zoom, themes, copy, and SVG/PNG/JPEG/WebP output up to 4×
- **Focused semantic GIF motion** — generated SVG in, validated GIF out; connectors begin absent and draw in semantic order. All twelve style contracts are user-approved. The shared `+2s-settled-flow` timing revision is also user-approved, so the default 5.75s/115-frame loop holds full settled flow on frames 38–109, then resets on 110–114
- **Visual review gate** — exported PNGs are inspected for clipping, overlap, label placement, and routing regressions before delivery
- **Product icons** — 40+ products with brand colors: OpenAI, Anthropic, Pinecone, Weaviate, Kafka, PostgreSQL…
- **Swim lane grouping** — automatic layer labeling for complex architectures
- **SVG + PNG output** — SVG for editing, 1920px PNG for embedding
- **Renderer-friendly** — pure inline SVG, no external font fetching; renders cleanly in cairosvg, rsvg-convert, and headless Chrome

---

## Loop Engineering

The first render is treated as a candidate, not an automatic final result. `fireworks-tech-graph` uses an agent-driven, bounded validation feedback loop to move each diagram toward a verified deliverable:

```text
Prompt
  → Diagram Contract
  → Semantic IR
  → Style Spec
  → Route Planner
  → SVG Build
  → Structural Validation
  → PNG Visual Readback
  → Targeted Revision
  → Verified SVG + PNG
```

The loop follows five design principles:

1. **Evaluate, don't assert** — completion is backed by validator and render evidence, not by the model saying the diagram looks correct.
2. **Deterministic checks first** — XML structure, marker integrity, path geometry, arrow-component collisions, and renderability are checked before visual judgment.
3. **Perceptual validation second** — the exported PNG is read back to inspect clipping, label collisions, hierarchy, whitespace, and routing quality that syntax checks cannot see.
4. **Targeted correction** — each pass changes only the diagnosed labels, coordinates, corridors, or spacing, then reruns validation and rendering.
5. **Bounded convergence** — visual review allows at most two focused correction passes by default, preventing an unbounded self-editing loop.

The loop is observable in the final status:

```text
validation: passed
visual_review: passed
```

If the runtime cannot read images, the skill reports `visual_review: skipped (image reader unavailable)` explicitly. The workflow remains bounded and auditable; it does not claim visual verification without image evidence.

## Installation

### Recommended: install the complete skill for both runtimes

Use the real nested skill path. The final `/skills/fireworks-tech-graph` segment is required because a bare repository install can select only the root `SKILL.md` in current versions of `skills` CLI.

```bash
npx -y skills@1.5.17 add \
  yizhiyanhua-ai/fireworks-tech-graph/skills/fireworks-tech-graph \
  --agent codex claude-code -g -y --copy
```

This creates complete copies at `~/.agents/skills/fireworks-tech-graph` for Codex and `~/.claude/skills/fireworks-tech-graph` for Claude Code, including scripts, schemas, fixtures, templates, tests, references, and metadata.

### Editable Git checkout for Codex

```bash
mkdir -p ~/.agents/skills
git clone https://github.com/yizhiyanhua-ai/fireworks-tech-graph.git ~/.agents/skills/fireworks-tech-graph
```

Codex discovers personal skills from `~/.agents/skills` and reads the optional `agents/openai.yaml` metadata included in this repository.

### Editable Git checkout for Claude Code

```bash
mkdir -p ~/.claude/skills
git clone https://github.com/yizhiyanhua-ai/fireworks-tech-graph.git ~/.claude/skills/fireworks-tech-graph
```

Claude Code discovers personal skills from `~/.claude/skills` and ignores the Codex-only UI metadata.

### One editable checkout shared by Codex and Claude Code

For a fresh install with Claude Code 2.1.203 or newer, keep one checkout and link both discovery paths to it. Move any existing destinations aside before creating the links.

```bash
mkdir -p ~/.local/share/agent-skills ~/.agents/skills ~/.claude/skills
git clone https://github.com/yizhiyanhua-ai/fireworks-tech-graph.git ~/.local/share/agent-skills/fireworks-tech-graph
ln -s ~/.local/share/agent-skills/fireworks-tech-graph ~/.agents/skills/fireworks-tech-graph
ln -s ~/.local/share/agent-skills/fireworks-tech-graph ~/.claude/skills/fireworks-tech-graph
```

This keeps `SKILL.md`, references, scripts, templates, and future updates identical in both agents. The npm registry is a separate distribution channel and may lag GitHub Releases. For the current Skill version, use the nested GitHub path above; the npm page remains available for package metadata:

```text
https://www.npmjs.com/package/@yizhiyanhua-ai/fireworks-tech-graph
```

## Update

For a `skills` CLI copy, rerun the recommended nested-path command. For Git installations, update whichever checkout you installed:

```bash
git -C ~/.agents/skills/fireworks-tech-graph pull
# or
git -C ~/.claude/skills/fireworks-tech-graph pull
# or, for the shared checkout
git -C ~/.local/share/agent-skills/fireworks-tech-graph pull
```

After the first install, restart Codex and Claude Code so both discover the skill. Later `SKILL.md` edits are detected automatically; restart the runtime after changing bundled scripts or references if the update is not visible.

The shell commands above target macOS, Linux, WSL, and Git Bash. On native Windows, use the equivalent `%USERPROFILE%\.agents\skills` and `%USERPROFILE%\.claude\skills` paths. Python 3.9+ is required; the optional Puppeteer path requires Node.js 18+.

---

## Unified CLI

```bash
SKILL_ROOT="${CLAUDE_SKILL_DIR:-$HOME/.agents/skills/fireworks-tech-graph}"

python3 "$SKILL_ROOT/scripts/fireworks.py" doctor
python3 "$SKILL_ROOT/scripts/fireworks.py" validate architecture "$SKILL_ROOT/fixtures/api-flow-style7.json"
python3 "$SKILL_ROOT/scripts/fireworks.py" render architecture "$SKILL_ROOT/fixtures/api-flow-style7.json" diagram.svg --report layout.json
python3 "$SKILL_ROOT/scripts/fireworks.py" check diagram.svg
python3 "$SKILL_ROOT/scripts/fireworks.py" export-html diagram.svg diagram.html --title "Agent Runtime Architecture"
python3 "$SKILL_ROOT/scripts/fireworks.py" animate diagram.svg diagram.gif
```

The HTML export is one offline file. It sanitizes the SVG, adds pan/zoom/reset, light and dark themes, SVG source copy, and SVG/PNG/JPEG/WebP downloads at 1×–4×.

For motion, say **“Generate a GIF”**, **“Animate this diagram”**, `生成 GIF`, `制作 GIF`, or `让这张图动起来`. The command accepts a generated semantic SVG that carries one of the twelve approved motion contracts. Exact source bytes are not pinned, so validated title and content variants of a supported topology work; missing or changed role/stage/order coverage, route direction, required colors, or geometry fails closed. GIF is the only motion media format, and the default command also writes `<output>.motion.json` as its verification report. The approved default is 960px, 5.75 seconds, 20fps, and 115 frame-center samples. All twelve scenes start connector-free, draw routes on frames 1–36, fade live flow on 36–38, hold full settled flow on 38–109, and reset on 110–114. Their approved identities include the packet heads, terminal evidence trace, Blueprint registration beads, 14×10 Notion memory cards, and the eight scene-specific signatures listed below. Default packages report both the style contract and shared `+2s-settled-flow` timing revision as `user-approved`. Timelines of 75 frames or fewer remain all-unique. Longer timelines allow non-adjacent repeated rasters inside the full-opacity interval; frame 110 is the sole boundary exception because its unchanged reset opacity is exactly 1.00, and such evidence is classified as `intentional_reset_boundary_repeat`. Frames 111–114 remain globally distinct. Long timelines require at least 75 unique rasters and forbid adjacent duplicates. The all-style 75-vs-115 gate counts binary-exact and decoded-RGBA-exact frames separately; compositor-only fallback is accepted only at AE ≤ 128, normalized RMSE ≤ 0.001, with components no thicker than 2px and confined to edge or node borders. DOM and signature geometry remain strict-exact. Explicit 3.75s/75-frame and 2.75s/55-frame calls remain supported. See [Focused SVG-to-GIF Motion](references/motion-effects.md).

| Style | Preset | Live signature |
|---:|---|---|
| 5 | `agent-orchestration` | glass task capsule + coordinator halo |
| 6 | `governed-runtime` | governance thread + policy seal |
| 7 | `token-stream` | API rail + three-cell token train |
| 8 | `golden-circuit` | luxury circuit rail + gem tracer |
| 9 | `review-trace` | review rail + moving review cursor |
| 10 | `cloud-flow` | region chevrons + replication capsule |
| 11 | `event-transit` | event train + exception/projection cars |
| 12 | `ops-pulse` | ECG/export heads + trace reveal + waterfall scanner |

---

## Requirements

The bundled SVG/PNG scripts require **cairosvg** (recommended) or `rsvg-convert`. Optional SVG-to-GIF export requires FFmpeg/FFprobe, Chrome/Chromium, and `puppeteer` or `puppeteer-core`.

```bash
# Recommended: cairosvg (best CSS support)
python3 -m pip install cairosvg

# Fallback: rsvg-convert (system package; may drop CSS / <foreignObject>)
brew install librsvg                   # macOS
sudo apt install librsvg2-bin          # Ubuntu/Debian

# Optional semantic motion export. Install beside every copied Skill because the
# renderer intentionally does not load modules from the caller's directory.
brew install ffmpeg                    # macOS; use your system package manager elsewhere
for SKILL_ROOT in \
  "$HOME/.agents/skills/fireworks-tech-graph" \
  "$HOME/.claude/skills/fireworks-tech-graph"
do
  [ -d "$SKILL_ROOT" ] || continue
  npm install --prefix "$SKILL_ROOT" --ignore-scripts --no-save --package-lock=false puppeteer-core@25.3.0
  python3 "$SKILL_ROOT/scripts/fireworks.py" doctor
done

# Verify either supported script renderer
python3 -c "import cairosvg; print(cairosvg.__version__)"
rsvg-convert --version
```

| Renderer | Quality | Install Cost | Use When |
|----------|---------|--------------|----------|
| **cairosvg** | ✅ Good | Single `python3 -m pip install` | Default — best balance |
| rsvg-convert | ⚠️ Fair | System package | No Python available, simple flat diagrams |
| puppeteer | ✅✅ Best | Node + Chromium | Manual browser-rendering path for D3, Mermaid, or pixel-perfect output |

---

## Why Not Mermaid or draw.io?

| | Mermaid | draw.io | **fireworks-tech-graph** |
|--|---------|---------|--------------------------|
| Natural language input | ✗ | ✗ | ✅ |
| AI/Agent domain patterns | ✗ | ✗ | ✅ |
| Multiple visual styles | ✗ | manual | ✅ 12 built-in |
| High-res PNG export | ✗ | manual | ✅ auto 1920px |
| Semantic arrow colors | ✗ | manual | ✅ auto |
| No online tool needed | ✅ | ✗ | ✅ |

Mermaid is great for quick inline diagrams in markdown. draw.io is great for manual polishing. `fireworks-tech-graph` is optimized for **describing a system and getting a polished diagram immediately**, without writing DSL syntax or clicking around a GUI.

Each style has a dedicated reference file in `references/` with exact color tokens and SVG patterns. Styles 1–7 and 9–12 are generator-backed; Style 8 uses AI-authored composition plus a static regression fixture.
The generator consumes structure fields such as `containers`, semantic `nodes[].kind`, `arrows[].flow`, and explicit port anchors. Styles 9–12 additionally validate domain-specific fields before layout.

Useful high-leverage fields for style-specific polish:
- `style_overrides` to nudge title alignment or palette tokens without forking a full style
- `containers[].header_prefix` / `containers[].header_text` for blueprint-style numbered section headers such as `01 // EDGE`
- `containers[].side_label` for Claude-style left layer labels
- `window_controls`, `meta_left`, `meta_center`, `meta_right` for terminal / document chrome
- `blueprint_title_block` for engineering title boxes in style 3

## AI/Agent Domain Patterns

Built-in pattern knowledge:

```
RAG Pipeline         → Query → Embed → VectorSearch → Retrieve → LLM → Response
Agentic RAG          → adds Agent loop + Tool use
Agentic Search       → Query → Planner → [Search/Calc/Code] → Synthesizer
Mem0 Memory Layer    → Input → Memory Manager → [VectorDB + GraphDB] → Context
Agent Memory Types   → Sensory → Working → Episodic → Semantic → Procedural
Multi-Agent          → Orchestrator → [SubAgent×N] → Aggregator → Output
Tool Call Flow       → LLM → Tool Selector → Execution → Parser → LLM (loop)
```

## Shape Vocabulary

Shapes encode semantic meaning consistently across all styles:

| Concept | Shape |
|---------|-------|
| User / Human | Circle + body |
| LLM / Model | Rounded rect, double border, ⚡ |
| Agent / Orchestrator | Hexagon |
| Memory (short-term) | Dashed-border rounded rect |
| Memory (long-term) | Solid cylinder |
| Vector Store | Cylinder with inner rings |
| Graph DB | 3-circle cluster |
| Tool / Function | Rect with ⚙ |
| API / Gateway | Hexagon (single border) |
| Queue / Stream | Horizontal pipe/tube |
| Document / File | Folded-corner rect |
| Browser / UI | Rect with 3-dot titlebar |
| Decision | Diamond |
| External Service | Dashed-border rect |

## Arrow Semantics

| Flow Type | Stroke | Dash | Meaning |
|-----------|--------|------|---------|
| Primary data flow | 2px solid | — | Main request/response |
| Control / trigger | 1.5px solid | — | System A triggers B |
| Memory read | 1.5px solid | — | Retrieve from store |
| Memory write | 1.5px | `5,3` | Write/store operation |
| Async / event | 1.5px | `4,2` | Non-blocking |
| Feedback / loop | 1.5px curved | — | Iterative reasoning |

## Troubleshooting

| Symptom | Cause | Fix |
|---------|-------|-----|
| PNG is blank or all-black | `@import url()` in SVG — neither cairosvg nor rsvg-convert can fetch external fonts | Remove `@import`, use system font stack |
| PNG not generated | No renderer installed | `python3 -m pip install cairosvg` (recommended), or `brew install librsvg` / `apt install librsvg2-bin` |
| Borders or text missing in PNG | Using `rsvg-convert` on SVG with CSS / `<foreignObject>` | Switch to `cairosvg` (`python3 -m pip install cairosvg`) — much better CSS support |
| Diagram cut off at bottom | ViewBox height too short | Increase `height` in `viewBox="0 0 960 <height>"` |
| Text overflowing boxes | Labels too long | Add `text-anchor="middle"` + `<clipPath>` or shorten label |
| Icons not rendering | External CDN URL | Use inline SVG paths from `references/icons.md` |
| Browser-generated SVG renders incorrectly | cairosvg / rsvg can't replay all CSS/JS-injected styles | Use `scripts/svg2png.js` as described in `references/png-export.md` |
