## What it does

figure-spec turns structured FigureSpec JSON into editable SVG files for architecture diagrams, workflows, pipelines, audit cascades, and system topology. With a fixed renderer version and fonts, the same specification produces the same SVG. The output remains plain text for manual edits.

The renderer validates the JSON schema and reports malformed specifications. It clips edges to node shapes, including rectangles, rounded boxes, circles, ellipses, and diamonds. Run it with `python3` through the `render`, `validate`, and `schema` commands.

Generation runs locally and needs no network access or API keys. The renderer file `figure_renderer.py` must resolve before SVG can be produced, so a failed lookup is a reason to check the installation.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill figure-spec -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/figure-spec/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/figure-spec/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill figure-spec -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/figure-spec/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill figure-spec -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/figure-spec/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install wanshuiyin/Auto-claude-code-research-in-sleep figure-spec
```

2. **Manually: put the files in place**
- File: `.github/skills/figure-spec/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill figure-spec -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/wanshuiyin/Auto-claude-code-research-in-sleep --path skills/figure-spec
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/figure-spec/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill figure-spec -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/wanshuiyin/Auto-claude-code-research-in-sleep/tree/HEAD/skills/figure-spec/SKILL.md

## When to use it
- generate an architecture diagram from FigureSpec JSON
- draw a pipeline with fixed step positions
- validate a diagram specification before rendering
- keep an SVG figure editable after generation
- connect nodes while respecting their shapes

## Example prompts
- Create an editable SVG architecture diagram from FigureSpec JSON with grouped nodes and labelled edges.
- Draw a left-to-right processing pipeline and save the result as an SVG file.
- Validate my FigureSpec JSON, then render it to `architecture.svg`.

Generate publication-quality **architecture diagrams**, **workflow pipelines**, **audit cascades**, and **system topology** figures as editable SVG vector graphics using a deterministic JSON → SVG renderer.

## When to Use This Skill

**Use `figure-spec`** for:
- System architecture diagrams (layered, hub-and-spoke, multi-plane)
- Workflow / pipeline figures
- Audit cascade / flow-control diagrams
- Any structured diagram where node positions, connections, and groupings are semantically important
- Figures that need to be edited/tweaked later (SVG is plain text)
- Figures where determinism matters (same spec → same SVG)

**Do NOT use for:**
- Data plots (bar/line/scatter) — use `/paper-figure`
- Natural/qualitative illustrations — use `/paper-illustration`
- Quick state-machine / flowchart — use `/mermaid-diagram` (lighter syntax)

## Core Properties

- **Deterministic**: identical FigureSpec JSON always produces identical SVG output (for a fixed renderer version + fonts)
- **Editable**: SVG output is plain-text, can be post-edited by hand or programmatically
