Generates .tldr JSON files and exports to PNG/SVG locally using @kitschpatrol/tldraw-cli. license: MIT homepage: https://github.com/Agents365-ai/tldraw-skill compatibility: Requires Node.js + @kitschpatrol/tldraw-cli on PATH (macOS/Linux/Windows). Self-check step requires a vision-enabled model (e.g., Claude Sonnet/Opus); gracefully skipped if unavailable. platforms: [macos, linux, windows] metadata: {"openclaw":{"requires":{"bins":["tldraw"]},"emoji":"📝","os":["darwin","linux","win32"],"install":[{"id":"npm-tldraw","kind":"npm","package":"@kitschpatrol/tldraw-cli","global":true,"bins":["tldraw"],"label":"Install tldraw-cli via npm"}]},"hermes":{"tags":["tldraw","diagram","flowchart","architecture","whiteboard","visualization"],"category":"design","requires_tools":["tldraw"],"related_skills":["drawio","mermaid","excalidraw","plantuml"]},"author":"Agents365-ai","version":"1.1.0"} --- # 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. ## Prerequisites ```bash # Install tldraw-cli npm install -g @kitschpatrol/tldraw-cli # Verify tldraw --version ``` Works identically on macOS, Windows, and Linux — no extra setup required. ## Workflow Before starting, assess whether the user's request is specific enough. If key details are missing, ask 1-3 focused questions: - **Diagram type** — which preset? (Architecture, Flowchart, Sequence, ML/DL, ERD, UML, or general) - **Output format** — PNG (default), SVG? - **Output location** — default is the user's working dir; honor any explicit path the user gives (e.g. "put it in `./artifacts/`"). Don't ask if they didn't mention one. - **Scope/fidelity** — how many components? Any specific technologies or labels? Skip clarification if the request already specifies these details or is clearly simple (e.g., "draw a flowchart of X"). 0. **Auto-update (first use per conversation)** — silently keep the skill current. Check the timestamp of `<this-skill-dir>/.last_update`. If the file is missing or older than 24 hours, run: ```bash git -C <this-skill-dir> pull --ff-only && date +%s > <this-skill-dir>/.last_update ``` If the pull fails (offline, conflict, not a git checkout, etc.), ignore the error and continue normally. Do not mention the update to the user unless they ask. 1. **Check deps** — verify `tldraw --version` succeeds; if missing, run `npm install -g @kitschpatrol/tldraw-cli`. 2. **Plan** — identify shapes (geo type per node), connections (arrows with source/target), and layout (TB or LR, group by tier/role). Sketch a coordinate grid before writing JSON. 3. **Generate** — write the `.tldr` JSON file. Default output dir is the user's working dir; if the user specified a path or directory (e.g. `./artifacts/`), `mkdir -p` it first and write there. Apply the same dir choice to PNG/SVG exports in steps 4 and 7. 4. **Export draft** — run CLI to produce a PNG for preview. 5. **Self-check** — use the agent's built-in vision capability to read the exported PNG, catch obvious issues, auto-fix before showing the user (requires a vision-enabled model such as Claude Sonnet/Opus). If vision is unavailable, skip this step. 6. **Review loop** — show image to user, collect feedback, apply targeted JSON edits, re-export, repeat until approved. 7. **Final export** — export the approved version to all requested formats; report file paths for both the `.tldr` source and exported image(s). ### Step 5: Self-Check After exporting the draft PNG, use the agent's vision capability (e.g., Claude's image input) to read the image and check for these issues before showing the user. If the agent does not support vision, skip self-check and show the PNG directly: | Check | What to look for | Auto-fix action | |-------|-----------------|-----------------| | Overlapping shapes | Two or more shapes stacked on top of each other | Shift shapes apart by ≥200px | | Clipped labels | Text cut off at shape boundaries | Increase shape `w`/`h` to fit label | | Missing arrows | Arrows that don't visually connect to shapes | Verify `boundShapeId` matches an existing shape's id | | Off-canvas shapes | Shapes at negative coordinates or far from the main group | Move to positive coordinates near the cluster | | Arrow-shape overlap | An arrow visually crosses through an unrelated shape | Adjust `bend` value or move endpoints to a different `normalizedAnchor` side | | Stacked arrows | Multiple arrows overlap each other on the same path | Distribute `normalizedAnchor` across the shape perimeter (use different x/y values) | - Max **2 self-check rounds** — if issues remain after 2 fixes, show the user anyway. - Re-export after each fix and re-read the new PNG. ### Step 6: Review Loop After self-check, show the exported image and ask the user for feedback. **Targeted edit rules** — for each type of feedback, apply the minimal JSON change: | User request | JSON edit action | |-------------|-----------------| | Change color of X | Find shape by `props.text` matching X, update `props.color` | | Add a new node | Append a new shape record with next available index, position near related nodes | | Remove a node | Delete the shape record and any arrow records bound to it | | Move shape X | Update the shape's `x`/`y` fields | | Resize shape X | Update `props.w`/`props.h` | | Add arrow from A to B | Append a new arrow record binding to A and B's shape ids | | Change label text | Update `props.text` on the matching shape or arrow | | Change layout direction | **Full regeneration** — replan the grid and rebuild | **Rules:** - For single-element changes: edit the existing JSON in place — preserves layout tuning from prior iterations. - For layout-wide changes (e.g., swap LR↔TB, "start over"): regenerate full JSON. - Overwrite the same `{name}.png` each iteration — do not create `v1`, `v2`, `v3` files. - After applying edits, re-export and show the updated image. - Loop continues until user says approved / done / LGTM. - **Safety valve:** after 5 iteration rounds, suggest the user open the `.tldr` file in tldraw.com or the desktop app for fine-grained adjustments. --- ## File Format ### Complete .tldr Skeleton ```json { "tldrawFileFormatVersion": 1, "schema": { "schemaVersion": 1, "storeVersion": 4, "recordVersions": { "asset": {"version": 1, "subTypeKey": "type", "subTypeVersions": {"image": 2, "video": 2, "bookmark": 0}}, "camera": {"version": 1}, "document": {"version": 2}, "instance": {"version": 17}, "instance_page_state": {"version": 3}, "page": {"version": 1}, "shape": {"version": 3, "subTypeKey": "type", "subTypeVersions": {"group": 0, "embed": 4, "bookmark": 1, "image": 2, "text": 1, "draw": 1, "geo": 7, "line": 0, "note": 4, "frame": 0, "arrow": 1, "highlight": 0, "video": 1}}, "instance_presence": {"version": 4}, "pointer": {"version": 1} } }, "records": [ {"id": "document:document", "typeName": "document", "gridSize": 10, "name": "", "meta": {}}, {"id": "page:page1", "typeName": "page", "name": "Page 1", "index": "a1", "meta": {}} /* shapes and arrows go here */ ] } ``` **Critical rules:** - `document:document` and `page:page1` records are ALWAYS required. - All shapes go in the `records` array after the page record. - All shapes have `"parentId": "page:page1"`. - Shape IDs use format `"shape:xxx"` with unique suffix (e.g., `"shape:s1"`, `"shape:a1"`). - `index` values MUST start with `"a"` followed by digits or uppercase letters: `"a1"`, `"a2"`, ..., `"a9"`, `"aA"`, `"aB"`, ..., `"aZ"`, `"a10"`, etc. - **Never use `"b1"`, `"c1"` etc. as indices** — only `"a*"` format is valid for shapes. --- ## Geo Shape Record ```json { "id": "shape:s1", "typeName": "shape", "type": "geo", "parentId": "page:page1", "index": "a1", "x": 100, "y": 100, "rotation": 0, "isLocked": false, "opacity": 1, "meta": {}, "props": { "w": 180, "h": 60, "geo": "rectangle", "color": "blue", "labelColor": "black", "fill": "semi", "dash": "draw", "size": "m", "font": "draw", "text": "API Gateway", "align": "middle", "verticalAlign": "middle", "growY": 0, "url": "" } } ``` ### Geo Types | `geo` value | Use for | |-------------|---------| | `rectangle` | services, modules, components | | `ellipse` | databases, start/end nodes | | `diamond` | decision points | | `cloud` | external services, infrastructure | | `hexagon` | event hubs, message buses | | `triangle` | gateways, load balancers | | `star` | highlights, key features | ### Color Palette | `color` | Use for | |---------|---------| | `blue` | clients, core services | | `green` | success, databases, storage | | `orange` | queues, event buses, warnings | | `red` | external APIs, errors, alerts | | `light-red` | soft alerts, secondary warnings | | `violet` | gateways, security, auth | | `yellow` | decisions, caches | | `grey` | neutral, background, legacy | | `light-blue` | secondary services, metadata | | `black` | titles, emphasis | ### Style Options | Property | Values | Notes | |----------|--------|-------| | `fill` | `semi`, `solid`, `none`, `pattern` | `semi` = tinted fill (recommended) | | `dash` | `draw`, `solid`, `dashed`, `dotted` | `draw` = hand-drawn default | | `size` | `s`, `m`, `l`, `xl` | `m` = default | | `font` | `draw`, `sans`, `serif`, `mono` | `draw` = default whiteboard style | --- ## Arrow Record ```json { "id": "shape:a1", "typeName": "shape", "type": "arrow", "parentId": "page:page1", "index": "aG", "x": 0, "y": 0, "rotation": 0, "isLocked": false, "opacity": 1, "meta": {}, "props": { "dash": "draw", "size": "m", "fill": "none", "color": "black", "labelColor": "black", "bend": 0, "start": { "type": "binding", "boundShapeId": "shape:s1", "normalizedAnchor": {"x": 0.5, "y": 1}, "isExact": false }, "end": { "type": "binding", "boundShapeId": "shape:s2", "normalizedAnchor": {"x": 0.5, "y": 0}, "isExact": false }, "arrowheadStart": "none", "arrowheadEnd": "arrow", "text": "", "font": "draw" } } ``` ### Arrow Connection Rules - Arrow record `x` and `y` are always `0, 0`. - Use `"type": "binding"` with `boundShapeId` to connect to a specific shape. - `normalizedAnchor` specifies WHERE on the target shape the arrow connects (0–1 range): - `{x: 0.5, y: 0}` = top center - `{x: 0.5, y: 1}` = bottom center - `{x: 0, y: 0.5}` = left center - `{x: 1, y: 0.5}` = right center - `{x: 0.5, y: 0.5}` = center - Add `"text": "label"` in arrow props for labeled connections. - Use `"bend": 20` (or `-20`) for slight curves to avoid overlap with other arrows. - For dashed/dotted arrows (e.g., async flows, optional links), set `"dash": "dashed"` or `"dotted"`. ### Distributing Arrows on a Shape When multiple arrows connect to the same shape, assign different `normalizedAnchor` points to prevent stacking: | Position | x | y | Use when | |----------|---|---|----------| | Top center | 0.5 | 0 | connecting to node above | | Top-left | 0.25 | 0 | 2nd connection from top | | Top-right | 0.75 | 0 | 3rd connection from top | | Right center | 1 | 0.5 | connecting to node on right | | Bottom center | 0.5 | 1 | connecting to node below | | Left center | 0 | 0.5 | connecting to node on left | **Rule:** if a shape has N connections on one side, space them evenly (e.g., 3 connections on bottom → x = 0.25, 0.5, 0.75). --- ## Index Ordering Rules Indices control z-order (stacking). Use this sequence: ``` a1, a2, a3, a4, a5, a6, a7, a8, a9, aA, aB, aC, aD, aE, aF, aG, aH, aI, aJ, aK, aL, aM, aN, aO, aP, aQ, aR, aS, aT, aU, aV, aW, aX, aY, aZ ``` - Geo shapes first: `a1` through `aF` (or as many as needed). - Arrow shapes after: `aG`, `aH`, etc. - Every shape must have a **unique** index. --- ## Layout Tips **Spacing — scale with complexity:** | Diagram complexity | Nodes | Horizontal gap | Vertical gap | |-------------------|-------|----------------|--------------| | Simple | ≤5 | 200px | 150px | | Medium | 6–10 | 280px | 200px | | Complex | >10 | 350px | 250px | **Routing corridors:** between shape rows/columns, leave an extra ~80px empty corridor where arrows can route without crossing other shapes. Never place a shape in a gap that arrows need to traverse. **Grid alignment:** snap all `x`, `y`, `w`, `h` values to **multiples of 10** — this matches tldraw's default `gridSize: 10` and makes manual editing easier. **General rules:** - Plan the grid before assigning x/y coordinates — sketch node positions mentally first. - Group related nodes in the same horizontal or vertical band. - Place heavily-connected "hub" nodes centrally so arrows radiate outward instead of crossing. - For wide shapes (like an API Gateway spanning multiple downstream services), set `w` to cover the full span. - Center-align a child node under its parent (same center x) to avoid diagonal routing. - **Event bus pattern**: place the bus (hexagon) in the **center of the service row**, not below — services on either side reach it with short horizontal arrows (`normalizedAnchor.x = 1` left side, `0` right side), eliminating crossings. - Horizontal connections never cross vertical nodes in the same row; use them for peer-to-peer and publish connections. **Avoiding arrow-shape overlap:** - Before finalizing coordinates, trace each arrow path mentally — if it must cross an unrelated shape, either move the shape or use `bend` to curve around. - For tree/hierarchical layouts: assign nodes to layers (rows), connect only between adjacent layers to minimize crossings. - For star/hub layouts: place the hub center, satellites around it — arrows stay short and radial. --- ## Diagram Type Presets When the user requests a specific diagram type, apply the matching preset below for shapes, colors, and layout conventions. ### Architecture Diagram | Element | `geo` | `color` | Notes | |---------|-------|---------|-------| | Client (web/mobile) | `rectangle` | `blue` | Top row, label by client type | | Service / module | `rectangle` | `blue` | Mid rows, group by tier | | Database | `ellipse` | `green` | Bottom row, one per service | | Cache | `ellipse` | `yellow` | Sits beside its owning service | | Queue / event bus | `hexagon` | `orange` | **Center of service row** for hub pattern | | Gateway / load balancer | `triangle` | `violet` | Above services | | External API | `cloud` | `red` | Edge of canvas, dashed arrows in | | Auth / security | `rectangle` | `violet` | Often near gateway | **Layout:** TB or LR by tier count; ≥4 tiers → TB. Hub nodes centered. Spacing scales with complexity (see table above). ### Flowchart | Element | `geo` | `color` | Notes | |---------|-------|---------|-------| | Start / End | `ellipse` | `green` | Always at top and bottom | | Process step | `rectangle` | `blue` | Default action box | | Decision | `diamond` | `yellow` | Always label outgoing arrows (Yes / No) | | I/O | `rectangle` (with `dash: dashed`) | `orange` | Distinguish from process via dashed border | | Subprocess | `rectangle` | `violet` | Indicates a callable sub-flow | **Layout:** TB, ~200px vertical gap. Decisions branch left/right, then merge back to center. Always label decision branches in the arrow's `props.text`. ### Sequence Diagram tldraw doesn't have native lifeline shapes. Approximate with: | Element | `geo` | `color` | Notes | |---------|-------|---------|-------| | Actor / object header | `rectangle` | `blue` | Top of column | | Lifeline | `rectangle` (`w: 2`, `fill: solid`, `color: grey`) | `grey` | Thin vertical line under each actor header | | Sync message | arrow with `arrowheadEnd: arrow` | `black` | Solid horizontal arrow | | Async message | arrow with `dash: dashed` | `black` | Dashed horizontal arrow | | Return message | arrow with `dash: dashed`, `color: grey` | `grey` | Grey dashed | **Layout:** LR for actors (200–280px apart), TB for time. Each message is a horizontal arrow between two lifelines at increasing `y`. ### ML / Deep Learning Model Diagram For neural network architecture diagrams — useful for paper figures and explainers. | Element | `geo` | `color` | Notes | |---------|-------|---------|-------| | Input / Output | `rectangle` | `green` | Top and bottom of stack | | Conv / Pooling | `rectangle` | `blue` | Standard layer block | | Attention / Transformer | `rectangle` | `violet` | Distinct color for self-attention blocks | | RNN / LSTM / GRU | `rectangle` | `yellow` | Recurrent layers | | FC / Linear | `rectangle` | `orange` | Dense projection layers | | Loss / Activation | `rectangle` | `red` | Final loss / softmax / activation | | Skip connection | arrow with `bend: 30`, `dash: dashed` | `grey` | Curved dashed bypass | **Tensor shape annotation:** include the dimensions in `props.text` on a second line. tldraw renders `\n` literally inside JSON strings, so use a real newline (the JSON encoder will write `\n`): ``` "text": "Conv2D\n(B, 64, 32, 32)" ``` **Layout:** TB (data flows top → bottom), layers ~150px apart. Skip connections curve around the main stack. ### ER Diagram (ERD) tldraw lacks native table/row shapes. Approximate each entity as a tall rectangle with multi-line text. | Element | `geo` | `color` | Notes | |---------|-------|---------|-------| | Entity | `rectangle` (`fill: solid`, `color: light-blue`) | `light-blue` | Title + columns as one multi-line text label | | Column list | embedded in `props.text` with `\n` between rows | — | Mark PK with `*` prefix, FK with `>` | | Relationship | arrow with `arrowheadStart: arrow`, `arrowheadEnd: arrow` | `black` | Both ends arrowed for many-to-many | | Optional / weak relationship | arrow with `dash: dashed` | `grey` | Dashed for optional FK | Label the arrow with cardinality (e.g., `1..*`, `0..1`) via `props.text`. **Layout:** TB or grid; entities spaced ≥300px apart to leave room for column lists. ### UML Class Diagram | Element | `geo` | `color` | Notes | |---------|-------|---------|-------| | Class | `rectangle` (`fill: solid`, `color: light-blue`) | `light-blue` | Title + attributes + methods as one multi-line `text` | | Inheritance | arrow with `arrowheadEnd: triangle` (open) | `black` | Use a single arrow shape; tldraw doesn't natively render hollow triangles, so suggest user open in editor for true UML notation if needed | | Composition | arrow with `bend: 0`, label `◆` in `text` | `black` | Add diamond glyph in arrow text as a workaround | | Association | arrow with `arrowheadEnd: arrow` | `black` | Standard arrow | **Note:** tldraw's arrowheads are limited compared to UML — for strict UML class diagrams, drawio-skill (separate skill) is a better fit. Use this preset for sketches and high-level explainers. **Layout:** TB, classes ~250px apart, interfaces above implementations. --- ## Export Commands ```bash # Check CLI version tldraw --version # PNG at 2x scale (recommended) — outputs diagram.png in ./ tldraw export diagram.tldr -f png --scale 2 -o ./ # SVG — outputs diagram.svg in ./ tldraw export diagram.tldr -f svg -o ./ # Transparent background tldraw export diagram.tldr -f png --scale 2 --transparent -o ./ # Dark theme tldraw export diagram.tldr -f png --scale 2 --dark -o ./ # Custom output directory (e.g. CI artifacts dir) — create if missing, then export there mkdir -p ./artifacts && tldraw export diagram.tldr -f png --scale 2 -o ./artifacts/ ``` **Note:** `-o` is an output **directory**, not a file path. The output file is named after the input file (`diagram.tldr` → `diagram.png`). ### Auto-launch after export Offer to open the `.tldr` file in the user's default tldraw viewer/editor: | OS | Command | |----|---------| | macOS | `open diagram.tldr` | | Linux | `xdg-open diagram.tldr` | | Windows | `start diagram.tldr` | Or upload to https://tldraw.com (drag-and-drop the `.tldr` file) for browser editing. --- ## Common Mistakes | Mistake | Fix | |---------|-----| | `tldraw` command not found | Run `npm install -g @kitschpatrol/tldraw-cli` | | `invalidRecords` on export | Check: index values must start with `a` (e.g., `a1`, `aA`) — never `b1`, `c1` | | Blank/empty export | Verify `document:document` and `page:page1` records are present | | Output file not found | `-o` is a directory; file name matches input: `tldraw export foo.tldr -o ./` → `./foo.png` | | Arrow doesn't appear | Use `"type": "binding"` with `boundShapeId`; set arrow `x`/`y` to `0,0` | | Shapes overlap | Plan a 200px+ grid before assigning x/y; scale spacing with complexity | | Text not visible | Check `props.text` is set; if `fill: "none"`, ensure text color contrasts | | Index collision | All shapes must have unique `index` values | | Shape ID clash | Use unique IDs: `"shape:s1"`, `"shape:s2"`, `"shape:a1"`, etc. | | Export fails | Ensure the `.tldr` file is valid JSON: `python3 -m json.tool file.tldr > /dev/null` | | Multi-line label | Use a real newline character inside the JSON string (`"text": "Line1\nLine2"`); tldraw respects `\n` | | Arrow crosses shape | Use `bend` to curve around, or move endpoint to a different `normalizedAnchor` | | Iteration loop never ends | After 5 rounds, suggest the user open `.tldr` in tldraw.com for fine-tuning | --- ## Fallback Chain When tools are unavailable, degrade gracefully: | Scenario | Behavior | |----------|----------| | `tldraw-cli` missing | Generate `.tldr` JSON only; instruct user to drag-and-drop into https://tldraw.com or install the CLI | | Vision unavailable for self-check | Skip self-check (step 5); proceed directly to showing user the exported PNG | | Export fails | Validate JSON with `python3 -m json.tool`; deliver the `.tldr` file and suggest opening in tldraw.com |

## What it does

- Generates `.tldr` JSON files from natural language descriptions
- Exports diagrams to PNG or SVG using `@kitschpatrol/tldraw-cli`
- **6 diagram type presets**: Architecture, Flowchart, Sequence, ML/Deep Learning, ERD, UML — with preset shape vocabulary and layout conventions
- **Self-check loop** — uses vision to read the exported PNG and auto-fix overlaps, clipped labels, and missing arrows before showing you
- **Iterative review loop** — collect feedback, apply targeted JSON edits, re-export until approved (5-round safety valve)
- **Complexity-scaled layout** — spacing automatically grows with node count to prevent overlaps
- **Auto-update** — pulls the latest skill version once per 24h
- **Custom output directory** — ask for any output path (e.g. `./artifacts/`) and the skill will `mkdir -p` and export there
- Triggers automatically when diagrams would help explain complex systems
- Hand-drawn whiteboard aesthetic by default; switchable to clean fonts

## Updates

The skill auto-checks for updates once per 24 hours on first use in a conversation (a single `git pull --ff-only`). The check is silent when up to date, offline, or not a git install — it won't block or slow the workflow.

To update manually:

```bash
cd <your-install-path>/tldraw-skill && git pull
```

## Usage

Just describe what you want:

```
Create a microservices e-commerce architecture with API Gateway, auth/user/order/product/payment services,
Kafka message queue, notification service, and separate databases for each service
```

The agent will plan the layout, generate the `.tldr` JSON, export to PNG, self-check, and let you iterate.

## Example

**Prompt:**
> Create a microservices e-commerce architecture with Mobile/Web/Admin clients, API Gateway,
> User/Order/Product/Payment services, Kafka event bus, Notification service,
> and User DB / Order DB / Product DB / Redis Cache / Stripe API

**Output:**

## Files

- `SKILL.md` — **the only required file**. Loaded by all platforms as the skill instructions.
- `README.md` — this file (English, displayed on GitHub homepage)
- `README_CN.md` — Chinese documentation
- `assets/` — example diagrams (safe to delete to save space)

> All example diagrams were generated by Claude with this skill.

## Known Limitations

- **Native UML notation**: tldraw arrowheads are limited (no hollow triangles for inheritance). Use drawio-skill for strict UML/ERD figures intended for academic papers
- **No native containers/swimlanes**: tldraw's grouping model differs from drawio. Use color and spacing for visual grouping instead
- **PDF export not supported**: tldraw-cli supports PNG and SVG only. Convert SVG to PDF post-hoc if needed (e.g. `rsvg-convert`)
- **Self-check requires vision**: The auto-fix step reads exported PNGs using the model's vision capability. Models without vision support skip this step

## 更新

skill 在每次会话首次使用时（每 24 小时一次）自动检查更新（一次 `git pull --ff-only`）。已是最新版、离线、或非 git 安装时会静默跳过 —— 不会阻塞或拖慢工作流。

手动更新：

```bash
cd <你的安装路径>/tldraw-skill && git pull
```

## 使用方式

直接描述你想要的图表：

```
画一个微服务电商架构图，包含 API Gateway、用户/订单/商品/支付服务、
Kafka 消息队列、通知服务，以及各自独立的数据库
```

Agent 会规划布局、生成 `.tldr` JSON、导出 PNG、自检，然后让你迭代。

## 示例

**提示词：**
> 画一个微服务电商架构图，包含 Mobile/Web/Admin 客户端，API Gateway，
> User/Order/Product/Payment 微服务，Kafka 事件总线，Notification 服务，
> User DB / Order DB / Product DB / Redis Cache / Stripe API

**输出效果：**

## 文件说明

- `SKILL.md` —— **唯一必需文件**。所有平台都加载此文件作为 skill 指令
- `README.md` —— 英文说明（GitHub 主页显示）
- `README_CN.md` —— 本文件（中文）
- `assets/` —— 示例图表（可安全删除以节省空间）

> 所有示例图表均由 Claude 使用本 skill 生成。

## 已知限制

- **原生 UML 标记**：tldraw 箭头有限（不支持继承所需的空心三角形）。学术论文中的严格 UML/ERD 图请使用 drawio-skill
- **无原生容器/泳道**：tldraw 的分组模型与 drawio 不同。请用颜色和间距实现视觉分组
- **不支持 PDF 导出**：tldraw-cli 仅支持 PNG 和 SVG。如需 PDF，可将 SVG 后处理转换（如 `rsvg-convert`）
- **自检需要视觉能力**：自动修复步骤通过模型的视觉能力读取 PNG。不支持视觉的模型会跳过此步
