Skill detail
drawio-skill
Create, edit, synchronize, inspect, test, and publish editable draw.io diagrams. Use when the user explicitly requests draw.io/diagrams.net, needs a polished architecture, ERD, UML, sequence, C4, SysML, BPMN, network, swimlane, ML, or infrastructure diagram, wants code/IaC/SQL/OpenAPI converted into a diagram, or wants an existing diagram queried, reviewed, diffed, restyled, kept in sync, or made interactive. Prefer Mermaid/PlantUML elsewhere when the requested artifact is diagrams-as-code rather than an editable draw.io file.
Why we recommend it: Creates, edits, and synchronizes editable draw.io architecture, ERD, UML, sequence, C4, network, and infrastructure diagrams, converting code/IaC/SQL/OpenAPI into diagrams.

# Draw.io Architecture Studio
Produce editable `.drawio` artifacts, not flattened pictures. The preferred
entrypoint is `scripts/diagramctl.py`, which unifies generation, incremental
sync, multi-view projection, semantic queries/tests/reviews, failure analysis,
and accessible publishing over a shared Diagram IR.
## Choose the workflow
| Request | Route |
| --- | --- |
| Natural-language diagram with precise styling | Read `references/diagram-types.md`, then `references/xml-authoring.md` and author XML |
| Standard flowchart/mindmap/gantt/timeline/etc. with no special styling | If draw.io >=30, read `references/mermaid-authoring.md` and convert Mermaid to native `.drawio` |
| Large graph (~15+ nodes) that needs automatic layout | Use `autolayout.py`; read `references/autolayout.md` before passing any `--layout` value |
| Code, Terraform, K8s, compose, SQL, OpenAPI, AsyncAPI, or CI source | Use `diagramctl.py build`; read `references/diagram-ir.md` |
| Protocol Buffers schema (.proto) | Use `protoimports.py` or `diagramctl.py build`; read `references/toolbox.md` |
| GraphQL SDL schema (.graphql/.gql) or introspection JSON | Use `graphqlerd.py` or `diagramctl.py build`; read `references/toolbox.md` |
| Running cluster/stack/cloud (actual state, not declared config) | Read `references/live-infra.md`, then use `tfstate.py`, `dockerimports.py`, or `k8simports.py -` |
| Update a generated diagram without losing manual layout | Use `diagramctl.py sync`; read `references/diagram-ir.md` |
| Executive/system/deployment/data-flow/security views | Use `diagramctl.py views`; read `references/diagram-ir.md` |
| Query, architecture policy, review, what-if, or guided walkthrough | Read `references/semantic-workflows.md` |
| MCP host (Claude Desktop, Cursor, VS Code, Codex) should call these workflows | Register `scripts/diagramctl_mcp.py`; read `references/mcp.md` |
| Prompt phrasing for a diagram type or semantic workflow | Read `references/cookbook.md` |
| Enforce architecture rules or visual diffs in GitHub Actions CI | Read `references/ci-gate.md` |
| Rendered before/after/diff images as a PR review comment | Use `prdiff.py`; read `references/pr-bot.md` |
| Existing `.drawio` to HTML/PPTX/Mermaid/Markdown/animation/runbook | Read `references/toolbox.md`; `diagramctl.py transform` exposes the existing tools |
| Pipeline, journey, or subsystem map drawn as a metro/subway map | Use `tubemap.py`; read `references/tubemap.md` Read the full source on GitHub (opens external page)
