Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
3 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by iflytek on GitHub. Read the source before you install it.

Installation

Install the Diagram Maker AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/iflytek/skillhub.git /tmp/skillhub
mkdir -p .claude/skills
cp -r /tmp/skillhub/builtin-skills/skills/diagram-maker .claude/skills/diagram-maker

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Diagram Maker in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Diagram Maker on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Diagram Maker is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Diagram Maker

Create diagrams as artifacts, not prose. Choose one output mode:

clean-svg: educational concepts, physical systems, processes, lifecycle, simple data flow.
architecture-svg: software/cloud/infra topology, services, databases, queues, trust zones.
excalidraw: editable hand-drawn whiteboard, flowchart, sequence, architecture sketch.

Routing

User wants editable/collaborative: choose Excalidraw.
User wants polished standalone browser output: choose SVG/HTML.
Software architecture with infra components: choose architecture SVG.
Science, product, process, concept map, physical object: choose clean SVG.
Unsure: ask one short question only if output format matters; otherwise choose clean SVG.

Workflow

Extract nodes, groups, labels, and directed relationships.
Pick layout first: left-to-right, top-down, hub-spoke, swimlanes, layered stack, sequence.
Keep labels short. Prefer 5-9 main elements over dense diagrams.
Generate the file at the requested path. If none is provided, use diagram.html or diagram.excalidraw in the current working directory.
Do not overwrite an existing file by default. Choose an unused suffixed name such as diagram-2.html, or ask before replacing the existing file.
Verify syntax by opening or parsing the output when feasible.

SVG/HTML rules

Single standalone .html file with inline CSS and inline SVG.
No external fonts, JS, images, gradients, glows, decorative blobs, or remote assets.
Use semantic colors, not rainbow sequences: neutral, input, process, storage, external, risk.
Draw connectors before nodes so arrows sit behind boxes.
Every connector path has fill="none" and a marker arrow when directed.
Leave 24px text padding inside boxes; do not let text touch borders.
Legend only when symbols/colors are not obvious.

SVG template

Use references/svg-template.md as the wrapper and replace .

Excalidraw rules

Save .excalidraw JSON with type, version, source, elements, and appState.
Use bound text for shape labels. Do not use a nonstandard label property.
Keep bound text immediately after its container in the elements array.
Minimum labeled shape: 120x60. Minimum body text: 16px.
Use roughness 1, fontFamily: 1, and simple fills.

For exact Excalidraw element snippets, read references/excalidraw-patterns.md.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Diagram Maker AI skill do?

Create standalone SVG/HTML or editable Excalidraw diagrams for concepts, architecture, processes, flows, and whiteboards.

Why use Diagram Maker on TypingMind?

Because you install it once and use it with any model. Diagram Maker is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Diagram Maker in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/iflytek/skillhub/tree/main/builtin-skills/skills/diagram-maker. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Diagram Maker?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Diagram Maker?

As many as you like. As long as a model supports skills, you can use Diagram Maker with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Diagram Maker AI skill free?

Yes. It is published on GitHub by iflytek under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
