Draw.io Architecture Studio

Generates, syncs, validates and publishes editable .drawio diagrams from plain requests or from code, IaC, SQL and OpenAPI sources.

Design & UIIntermediate★ 9,608⑂ 677AI score 9/10Last updated: Sep 14, 2026

What it does

  • Produces editable .drawio files (not flattened images) for architecture, ERD, UML, sequence, C4, SysML, BPMN, network, swimlane and infrastructure diagrams.
  • Converts Terraform, Kubernetes, docker-compose, SQL, OpenAPI and CI configs into a shared Diagram IR, then renders diagrams with provenance.
  • sync updates a generated diagram when sources change while preserving manual layout; views projects executive/system/deployment/dataflow/security perspectives.
  • Adds semantic tooling: test (architecture policy rules), review (markdown findings), query (reachability), whatif (failure impact), story (accessible HTML walkthrough).
  • Enforces a disciplined pipeline: structural validation, draft PNG visual inspection with overlap/clipping fixes, then final PNG/SVG/PDF exports with fixed CLI invariants.

Who it's for

  • Engineers and architects who need diagrams that stay editable and reviewable.
  • Platform/DevOps teams keeping architecture diagrams in sync with real IaC repos.
  • Security or governance owners wanting architecture rules checked in CI.

Example uses

  1. "Diagram my Terraform in ./infra" → diagramctl.py build ./infra --from terraform --ir-output architecture.ir.json.
  2. "Is orders-db reachable from the internet?" → query --from internet --to orders-db.
  3. "Show blast radius if Kafka fails" → whatif --fail kafka --drawio kafka-failure.drawio.

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/drawio-skill folder from the GitHub repo Agents365-ai/drawio-skill into my ~/.claude/skills/drawio-skill/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/Agents365-ai/drawio-skill.git && mkdir -p ~/.claude/skills && cp -r drawio-skill/skills/drawio-skill ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and confirm Python 3 is available: python3 --version
  2. Clone the repo: git clone https://github.com/Agents365-ai/drawio-skill.git
  3. Copy the skill into Claude Code's skills folder: mkdir -p ~/.claude/skills && cp -r drawio-skill/skills/drawio-skill ~/.claude/skills/
  4. (Optional) For native PNG/PDF/SVG exports install the draw.io desktop app: on macOS run brew install drawio
  5. (Optional) For automatic layout of large graphs install Graphviz: brew install graphviz
  6. Verify the toolchain: python3 ~/.claude/skills/drawio-skill/scripts/diagramctl.py doctor
  7. Restart Claude Code, then ask something like "build a draw.io architecture diagram from my Terraform folder".
