## What it does

The skill writes whiteboard diagrams as `.tldr` JSON files and converts them to PNG or SVG using `@kitschpatrol/tldraw-cli`. Vision-enabled models inspect the draft PNG before presenting it. The workflow catches disconnected arrows, overlapping text labels, and shapes pushed outside the canvas.

Prerequisites include Node.js and `@kitschpatrol/tldraw-cli` on PATH. Diagram export relies on Puppeteer. If the first run throws `Could not find Chrome`, install the required build once with `npx puppeteer browsers install chrome@<version-from-error>`.

Shapes in tldraw lack opaque fills, and the tool relies on manual coordinate grids. For automatic layout of large node graphs, Mermaid remains a better fit.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Agents365-ai/365-skills --skill tldraw-skill -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Agents365-ai/365-skills --skill tldraw-skill -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Agents365-ai/365-skills --skill tldraw-skill -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Agents365-ai/365-skills tldraw-skill
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Agents365-ai/365-skills --skill tldraw-skill -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Agents365-ai/365-skills --path plugins/tldraw/skills/tldraw-skill
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Agents365-ai/365-skills --skill tldraw-skill -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/Agents365-ai/365-skills/tree/HEAD/plugins/tldraw/skills/tldraw-skill/SKILL.md

## When to use it
- generate whiteboard-style architecture diagrams for multi-service apps
- map data pipelines and multi-step processes as flowcharts
- build .tldr JSON files with connected shapes and arrows
- export whiteboard diagrams to local PNG or SVG images

## Example prompts
- Draw an architecture diagram showing the auth flow and database in PNG
- Create a flowchart of our payment processing pipeline in tldraw format
- Sketch a whiteboard diagram for these three microservices into ./artifacts/

# tldraw Whiteboard Diagrams

## Overview

Generate modern whiteboard-style diagrams as `.tldr` JSON files and export to PNG/SVG using `@kitschpatrol/tldraw-cli`. tldraw produces clean hand-drawn aesthetic diagrams with rich shape libraries and smooth arrow routing — well-suited for casual or whiteboard-style visualizations.

**Format:** `.tldr` JSON
**Export:** PNG, SVG (via `@kitschpatrol/tldraw-cli`)
**Aesthetic:** Hand-drawn whiteboard style by default; switchable to clean fonts via `font` prop.

## When to Use

**Explicit triggers:** user says "diagram", "flowchart", "draw", "visualize", "whiteboard diagram", "tldraw diagram", "architecture diagram", "sketch this out".

**Proactive triggers:**

- Explaining a system with 3+ interacting components
- Describing a multi-step process, data flow, or pipeline
- Showing relationships between services/modules
- Architecture overviews, sequence flows, decision trees, ML model layers

**Skip when:** a simple list or table suffices, the user wants a polished business-presentation diagram (prefer drawio-skill), or the user is in a quick Q&A flow.

**When NOT to use it — route elsewhere:**

- Logos / solid-color graphics / filled icons: tldraw has **no opaque fill** (`solid` = light tint; white-on-dark can't be reproduced) → use the **drawio** skill or the original vector file.
- Precise vector geometry or strict (hollow-arrow) UML → **drawio** (or **plantuml** for UML).
- Auto-layout of many nodes → **mermaid** (tldraw needs manual coordinates).
- A pixel-faithful copy of an existing image → not a diagram-skill task.

## Prerequisites

```bash
# Install tldraw-cli
npm install -g @kitschpatrol/tldraw-cli

# Verify
tldraw --version
```

Works identically on macOS, Windows, and Linux.
