# figure-description

Reads your patent drawings, numbers their parts and produces formal figure descriptions. Useful when the diagrams exist but the reference numerals and captions do not.

## What it does

The skill scans the project for image files (PNG, JPG, SVG, PDF), checking `patent/figures/`, then `figures/` and the root, and opens each one with the Read tool. For every figure it works out which components are shown, how they connect, and the order of steps when the image is a flowchart.

Numbering runs in series: FIG. 1 takes 100–199, FIG. 2 takes 200–299. A part that recurs across figures keeps its numeral. Descriptions come in Chinese for CN filings or English for US/EP. Two files get written — `patent/figures/figure_descriptions.md` and `patent/figures/numeral_index.md`, the latter mapping each numeral to a component, a figure and a claim element.

The claim check is the part that catches mistakes: an element with no drawing or no numeral gets flagged as `[MISSING FIGURE: ...]` or `[MISSING NUMERAL: ...]`. Your images are left untouched. `patent/INVENTION_DISCLOSURE.md` and `patent/CLAIMS.md` have to be in place first, because the numeral-to-claim mapping is built from them.

## Install

### Claude Code (native platform)

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

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

### Codex

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

2. **Manually: put the files in place**
- File: `.agents/skills/figure-description/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-description -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/figure-description/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-description
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/figure-description/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-description -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-description/SKILL.md

## When to use it
- assign reference numerals to drawing components in 100/200 series
- draft formal figure captions for a patent application
- map each claim element to a numeral on a figure
- spot claim elements with no matching drawing
- build one index of all reference numerals

## Example prompts
- Process the figures in `patent/figures/` and write descriptions with reference numerals
- Check whether every element in `patent/CLAIMS.md` has a numeral in a figure
- Build a numeral index for FIG. 1 and FIG. 2 using the US format

# Figure Description for Patents

Process patent figures and generate drawing descriptions based on: **$ARGUMENTS**

Unlike `/paper-figure` which generates data plots, this skill processes user-provided technical diagrams and assigns reference numerals.

## Constants

- `FIGURE_DIR = "patent/figures/"` — Output directory for figure descriptions
- `REFERENCE_NUMERAL_PREFIX = 100` — Starting numeral for first figure's components
- `NUMERAL_SERIES = 100` — Each figure uses a separate 100-series (Fig 1: 100-199, Fig 2: 200-299, etc.)

## Inputs

1. User-provided figures (PNG, JPG, SVG, PDF) — search for them in the project directory
2. `patent/INVENTION_DISCLOSURE.md` — for understanding what components to identify
3. `patent/CLAIMS.md` — for mapping numerals to claim elements

## Workflow

### Step 1: Discover Figures

1. Search the project directory for figure files:
   - Check `patent/figures/`, `figures/`, root directory
   - Look for PNG, JPG, SVG, PDF files
   - Check INVENTION_BRIEF.md or INVENTION_DISCLOSURE.md for figure references
2. List all discovered figures with their paths
3. If figures are missing that claims require, note them as `[MISSING: description needed]`

### Step 2: Analyze Each Figure

For each figure found:

1. **Read the image** using the Read tool (supports image files)
2. **Identify components**: What labeled or visually distinct components are shown?
3. **Identify connections**: How do components relate to each other?
4. **Identify flow**: If it's a flowchart or sequence, what is the step order?

### Step 3: Assign Reference Numerals

For each figure, assign numerals using the series convention:

| Figure | Numeral Range |
|--------|-------------|
| FIG. 1 | 100-199 |
| FIG. 2 | 200-299 |
| FIG. 3 | 300-399 |

For each identified component:
- Assign the next available numeral in the series
- Cross-reference to the claim elements it supports
- Note if a component appears in multiple figures (use same numeral across figures)
```
