It can also turn an **existing codebase** (Python / JS-TS / Go / Rust), **Terraform / Kubernetes / docker-compose infrastructure**, or a **SQL schema** into an auto-laid-out diagram. Works with **Claude Code, Cursor, Copilot, OpenClaw, Codex, Autohand Code, Hermes**, and any agent compatible with the [Agent Skills](https://agentskills.io) format.

Microservices Architecture — generated from a single natural-language prompt

## ✨ Highlights - **11 diagram type presets** — ERD, UML Class, Sequence, C4, Architecture, ML/Deep Learning, Flowchart, SysML (BDD / IBD / Requirement / Parametric), BPMN, Network Topology, Cross-Functional Swimlane - **Mermaid → native .drawio** (draw.io ≥ 30) — author 28 standard types as Mermaid text (**mindmap, gantt, timeline, journey, pie, sankey, kanban**…) and the CLI converts them into a laid-out, editable `.drawio` — structure in, layout free - **Visualize a codebase** — extract and auto-lay-out the structure of a Python / JS-TS / Go / Rust project (import graphs) or a Python class hierarchy — Graphviz placement, transitive reduction, nested module containers - **IaC → architecture diagram** — turn **Terraform** configs, **Kubernetes** manifests, or **docker-compose** files into an architecture diagram where every resource renders as its **official AWS / Azure / GCP / K8s icon**, edges derived from actual references (role ARNs, selectors, volume mounts) - **SQL DDL → ER diagram** — parse `CREATE TABLE` statements into per-table nodes with PK/FK markers and crow's-foot foreign-key edges - **Deterministic sequence diagrams** — describe participants + messages as JSON; lifelines, auto-tracked activation bars, and arrows are computed, never hand-placed - **C4 model with drill-down** — one command generates the multi-page System Context → Container → Component set with official C4 shapes; parent elements **click through** to their child page - **Search 10,000+ official shapes** — resolve the exact AWS / Azure / GCP / Cisco / Kubernetes / UML / BPMN icon style instead of guessing (no more blank-box `shape=mxgraph.*` typos) - **AI / LLM brand logos** — 321 logos (OpenAI, Claude, Gemini, Mistral, Llama, Ollama, LangChain…) that draw.io has none of, plus **18 data-store brands** (Redis, Postgres, Qdrant, Milvus…) for LLM/RAG architecture diagrams - **Self-check + auto-fix** — reads its own PNG output and auto-fixes overlaps, clipped labels, stacked edges, and more (up to 2 rounds) - **Iterative feedback loop** — up to 5 rounds of targeted refinement - **Style presets** — capture your visual style from a `.drawio` file or image, reuse on demand - **Clean layout** — grid-aligned, spacing scales with diagram size, connectors routed clear of nodes - **Multi-agent, zero-config** — runs from a single SKILL.md; no MCP server, no background daemon (the optional `npx` installer needs Node, the skill itself does not) ## 🗺️ Feature Map
drawio-skill feature map — one mind map covering every capability, itself drawn with the skill
A bird's-eye view of everything the skill does — diagram types, import sources, layout engines, styling, export formats, and repurposing — in one map. Fittingly, this map was itself drawn with drawio-skill. ## 🖼️ Examples > [!TIP] > **The hero image above was generated from this single prompt:** ``` Create a microservices e-commerce architecture with Mobile/Web/Admin clients, API Gateway (auth + rate limiting + routing), Auth/User/Order/Product/Payment services, Kafka message queue, Notification service, and User DB / Order DB / Product DB / Redis Cache / Stripe API ``` The skill is designed to route edges cleanly across different topologies, avoiding lines that cross through shapes:
Star topology
Star · 7 nodes
Central message broker with 6 microservices radiating outward, no edge crossings on this example. 		Layered flow
Layered · 10 nodes / 4 tiers
E-commerce stack with horizontal and diagonal cross-connections routed via corridors. 		Ring cycle
Ring · 8 nodes
CI/CD pipeline with a closed loop and 2 spur branches flowing along the perimeter.
It also speaks **Mermaid** — standard types (flowchart, mindmap, **kanban**, gitGraph, timeline…) convert straight to native, editable `.drawio`. Here's a Kanban board (this project's own roadmap) generated from a few lines of Mermaid:
Kanban board generated by drawio-skill from Mermaid — this project's roadmap across Backlog / Todo / In Progress / Done
**Tube-Map Mode** restyles a pipeline or journey as a London-Underground-style metro map — coloured lines, octilinear (H/V/45°) routing, and white interchange circles. Here's the skill's own flow (this map is `assets/tubemap.json`, ~20 lines):

Full walkthrough in [docs/USAGE.md](https://github.com/agents365-ai/drawio-skill/blob/HEAD/docs/USAGE.md). ## 🚀 Installation ### 1. Install the draw.io desktop CLI | Platform | Command | |----------|---------| | **macOS** | `brew install --cask drawio` | | **Windows** | [Download installer](https://github.com/jgraph/drawio-desktop/releases) | | **Linux** | `.deb`/`.rpm` from [releases](https://github.com/jgraph/drawio-desktop/releases); `sudo apt install xvfb` for headless | Verify with `drawio --version`. **Version ≥ 30 recommended** — it unlocks Mermaid → `.drawio` conversion and the ELK `--layout` pass (both unavailable on ≤ 29). On **WSL2** the CLI is the Windows desktop exe reached via `/mnt/c` — the skill detects this automatically (see [troubleshooting](https://github.com/agents365-ai/drawio-skill/blob/HEAD/skills/drawio-skill/references/troubleshooting.md)). Full recipes in [docs/INSTALL_CLI.md](https://github.com/agents365-ai/drawio-skill/blob/HEAD/docs/INSTALL_CLI.md). ### 2. Install the skill ```bash # Any agent (Claude Code, Cursor, Copilot, ...) npx skills add Agents365-ai/365-skills -g ``` ```text # Claude Code plugin marketplace > /plugin marketplace add Agents365-ai/365-skills > /plugin install drawio ``` ```bash # Manual install git clone https://github.com/Agents365-ai/drawio-skill.git \ ~/.claude/skills/drawio-skill # Autohand Code global install git clone https://github.com/Agents365-ai/drawio-skill.git \ ~/.autohand/skills/drawio-skill # Autohand Code project-level install git clone https://github.com/Agents365-ai/drawio-skill.git \ .autohand/skills/drawio-skill ``` Autohand Code also supports `autohand --skill-install` for cataloged skills, with `--project` for workspace-level installs. Until this skill is listed there, use the direct clone path above. Also indexed on [SkillsMP](https://skillsmp.com/skills/agents365-ai-drawio-skill-skills-drawio-skill-skill-md) and [ClawHub](https://clawhub.ai/agents365-ai/drawio-pro-skill). **Updating:** `/plugin update drawio` (Claude Code), `skills update drawio-skill` (SkillsMP), `clawhub update drawio-pro-skill` (OpenClaw), or `git pull` for manual installs — see [docs/INSTALL_SKILL.md#updates](https://github.com/agents365-ai/drawio-skill/blob/HEAD/docs/INSTALL_SKILL.md#updates). Release history in [CHANGELOG.md](https://github.com/agents365-ai/drawio-skill/blob/HEAD/CHANGELOG.md). ## ⚡ Quick Start After installation, just describe what you want. For example, an ML model: ``` Draw a Transformer encoder-decoder for machine translation: 6-layer encoder with self-attention, 6-layer decoder with cross-attention, input embeddings (batch × 512 × 768), positional encoding, and a final output projection. Annotate tensor shapes between layers and color-code by layer type. ``` The skill plans the layout, generates the `.drawio` XML, exports to your chosen format, self-checks the result, and lets you iterate. ## 🗺️ Visualize Code & Infrastructure Beyond hand-authored diagrams, the skill turns **existing code, infrastructure, and schemas into diagrams** — no manual coordinates. Just ask: > *"Visualize the module structure of this Python project"* · *"Draw the class hierarchy of `mypackage`"*

Auto-generated class hierarchy of Python's logging package — modules boxed, inheritance arrows resolved

↑ Python's logging package as a class hierarchy — one command, modules auto-boxed, every inheritance edge resolved.

One diagram → EN + CN twins for bilingual docs | | **Re-theme** | `restyle.py` applies a style preset (built-in `dark`/`corporate`/… or your own) to an *existing* `.drawio` — palette remapped by hue so same-colored nodes stay grouped; layout and edge routing untouched | | **Metric heat map** | `heatmap.py` recolours an existing `.drawio` from a CSV/JSON of per-node values — cost / latency / traffic / error-rate shaded low→high on a gradient (optional size-by-value + legend), matched by cell id or label | | **Architecture time-lapse** | `timelapse.py` re-runs an importer across a repo's git history and assembles a self-contained HTML player — watch modules & edges appear over time (▶ play / ‹ › step) | | **Diagram → Markdown** | `explain.py` reverses a `.drawio` into a structured description — components by tier, relations, per-page for C4 — for dropping an architecture summary into a README or PR | | **Interactive viewer** | `drawiohtml.py` publishes a `.drawio` as one self-contained HTML — page tabs, drag-pan, wheel-zoom, node search, and a C4 model's drill-down links keep working. Share the file; no draw.io, no server | | **Diagram → PowerPoint** | `drawio2pptx.py` turns a multi-page diagram into a 16:9 deck (one page per slide, page name as title) — a C4 model becomes a ready-to-present slideshow | | **Animated data-flow** | `svgflow.py` makes a diagram's edges *flow* (marching-ants animation along each arrow) — a self-contained looping SVG that renders on GitHub, in docs, or as a slide background | | **Diagram → Mermaid** | `drawio2mermaid.py` converts a `.drawio` into a Mermaid `flowchart` (containers → subgraphs, edge labels kept) — paste it into Markdown as diagrams-as-code that GitHub renders natively | | **Sequence engine** | `seqlayout.py` computes lifeline / activation-bar / arrow geometry from a message list — no Graphviz, no hand placement | | **Auto-layout** | Graphviz places nodes and routes orthogonal edges *around* them — removes the manual-coordinate ceiling for large graphs. `--tune` tries both directions and keeps the more readable one | | **Transitive reduction** | drops edges implied by a longer path, turning a dense hairball into a traceable graph (asyncio: 149 → 46 edges) | | **Nested containers** | `--group` boxes modules by sub-package, nested for deep package trees | | **Deterministic validator** | `validate.py` lints the `.drawio` (dangling edges, duplicate ids, overlaps) before the visual self-check | Layout needs Graphviz (`brew install graphviz` / `apt install graphviz`) — optional; everything else works without it. Full format + flag reference in [references/autolayout.md](https://github.com/agents365-ai/drawio-skill/blob/HEAD/skills/drawio-skill/references/autolayout.md). Regenerate, validate (`--strict` gate) and render headlessly in CI: [docs/CI.md](https://github.com/agents365-ai/drawio-skill/blob/HEAD/docs/CI.md). ## 🧩 Supported Diagram Types | Category | Examples | Notable features | |---|---|---| | Architecture | microservices, cloud (AWS/GCP/Azure), network topology, deployment | Tier-based swimlanes, hub-center strategy | | C4 model | system context, containers, components | Multi-page `.drawio`, click-to-drill-down links | | ML / Deep Learning | Transformer, CNN, LSTM, GRU | Tensor shape annotations, layer-type color coding | | Flowcharts | business processes, workflows, decision trees, state machines | Semantic shapes (parallelogram I/O, diamond decisions) | | UML | class diagrams, sequence diagrams | Inheritance / composition / aggregation arrows; lifelines + activation boxes | | SysML / MBSE | block definition (bdd), internal block (ibd), requirement (req), parametric (par) | «block» / «requirement» compartments, satisfy/derive/verify edges, native `mxgraph.sysml.*` ports & flows | | BPMN | business processes, pools & lanes | Native `mxgraph.bpmn.*` events/tasks/gateways, sequence vs message flows | | Network topology | LAN/WAN, subnets, DMZ | `mxgraph.networks.*` device shapes, zone containers, link labels; Cisco/rack via shape search | | Cross-functional swimlane | who-does-what processes, handoffs | Pool + role lanes, flowchart vocabulary, orthogonal handoff edges | | Data | ER diagrams, data flow diagrams (DFD) | Table containers, PK/FK notation | | Mermaid-authored | mind maps, gantt, timeline, journey, pie, sankey, kanban + 20 more | Native CLI conversion (≥ v30) — structure only, layout free | | Other | org charts, wireframes | — | ## 🔍 Shape Search Need a real AWS / Azure / GCP / Cisco / Kubernetes / UML / BPMN icon? The skill searches **10,000+ official draw.io shapes** for the exact style string — so vendor icons render correctly instead of falling back to a blank box from a guessed `shape=mxgraph.*` name. > *"Add an AWS Lambda wired to an S3 bucket"* · *"Use the real Kubernetes pod icon"* ```bash python3 scripts/shapesearch.py "aws lambda" --limit 5 # → Lambda (77x93) # outlineConnect=0;...;shape=mxgraph.aws3.lambda;fillColor=#F58534;... ```

Serverless AWS architecture built from official draw.io icons resolved by shapesearch.py

↑ A serverless AWS architecture — every icon is the real official draw.io shape resolved by shapesearch.py, not a hand-guessed shape= string. Covers AWS / Azure / GCP / Cisco / Kubernetes / UML / BPMN / ER / electrical / P&ID and the general shape sets. Hand-writable style cheatsheet + search usage in [references/shapes.md](https://github.com/agents365-ai/drawio-skill/blob/HEAD/skills/drawio-skill/references/shapes.md). ## 🤖 AI / LLM Brand Logos draw.io ships **no** modern AI/LLM logos, so an LLM-app diagram renders as generic boxes. `aiicons.py` resolves a brand name to a draw.io image style for any of **321 logos** (OpenAI, Claude, Gemini, Mistral, Llama, Cohere, DeepSeek, Qwen, Ollama, LangChain, HuggingFace…) from [lobe-icons](https://github.com/lobehub/lobe-icons) (MIT), plus **18 data-store brands** (Redis, Postgres, MongoDB, Qdrant, Milvus, Supabase…) via [simple-icons](https://simpleicons.org) (CC0) for RAG stacks. ```bash python3 scripts/aiicons.py "claude" --json # CDN-referenced (default) python3 scripts/aiicons.py "openai" --embed # self-contained data URI ```

Multi-provider LLM app diagram with real AI brand logos resolved by aiicons.py

↑ A multi-provider LLM app — every brand logo resolved by aiicons.py. Icons are referenced from the unpkg CDN by default (network needed at render time); --embed inlines them for offline use. Logos are trademarks of their owners, used for identification only. ## 🎨 Style Presets Capture a visual style once, reuse it everywhere. Five presets are built in — `default`, `corporate`, `handdrawn`, `colorblind-safe` (Okabe-Ito palette), `dark` — and you can teach the skill your own style from a `.drawio` file or a flat image: ``` Draw a microservices architecture using my "corporate" style ``` ``` Learn my style from ~/diagrams/brand.drawio as "mybrand" ``` The skill extracts colors, shapes, fonts, and edge style, renders a preview, and only saves the preset after you approve. Full preset-management commands in [docs/STYLE_PRESETS.md](https://github.com/agents365-ai/drawio-skill/blob/HEAD/docs/STYLE_PRESETS.md). ## 🔄 How it works

Internal workflow

Behind the scenes: **check dependencies → plan layout → generate `.drawio` XML → export draft PNG → self-check + auto-fix** (up to 2 rounds) → **show to user → 5-round feedback loop** until approved → **final export**. ## 🆚 Comparison ### vs Native Agent (no skill) | Feature | Native agent | drawio-skill | |---|---|---| | Self-check after export | ❌ | ✅ reads PNG, auto-fixes 6 issue types | | Iterative review loop | ❌ manual re-prompt | ✅ targeted edits, 5-round safety valve | | Diagram type presets | ❌ | ✅ 7 presets (ERD, UML, Seq, C4, Arch, ML, Flow) | | Mermaid → editable .drawio | ❌ | ✅ 28 types via native CLI conversion (≥ v30) | | Visualize a codebase | ❌ | ✅ import graphs (Py/JS/Go/Rust) + class diagrams | | IaC → architecture diagram | ❌ | ✅ Terraform / K8s / compose → official cloud icons | | SQL DDL → ER diagram | ❌ | ✅ `CREATE TABLE` → PK/FK tables, crow's-foot edges | | Sequence diagrams | ❌ hand-placed coordinates | ✅ deterministic geometry engine (`seqlayout.py`) | | C4 model | ❌ | ✅ multi-page Context→Container→Component with click-to-drill-down | | Auto-layout for large graphs | ❌ hand-places, overlaps | ✅ Graphviz placement, ortho routing, nested containers | | Structural validation | ❌ | ✅ deterministic `.drawio` linter | | Official shape search | ❌ guesses, blank boxes | ✅ exact style for 10k+ AWS/Azure/GCP/UML shapes | | AI/LLM brand logos | ❌ none | ✅ 321 AI + 18 data-store logos via aiicons.py | | Grid-aligned layout | ❌ | ✅ 10px snap, routing corridors | | Color palette | random / inconsistent | ✅ 7-color semantic system | | Style presets | ❌ | ✅ learn from `.drawio` file or image | ### vs Other draw.io Skills & Tools | Feature | drawio-skill | [jgraph/drawio-mcp](https://github.com/jgraph/drawio-mcp) (official)
