--- name: drawio-skill description: 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/AsyncAPI/Protobuf 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. license: MIT allowed-tools: [Bash, Read, Write, WebFetch] metadata: {"openclaw":{"requires":{"anyBins":["python3"]},"emoji":"📐","os":["darwin","linux","win32"],"install":[{"id":"brew-drawio","kind":"brew","formula":"drawio","bins":["drawio"],"label":"Install draw.io for native exports","os":["darwin"],"optional":true},{"id":"brew-graphviz","kind":"brew","formula":"graphviz","bins":["dot"],"label":"Install Graphviz for automatic layout","os":["darwin"],"optional":true}]},"hermes":{"tags":["drawio","diagram","architecture","visualization","uml"],"category":"design","requires_tools":["python3"],"related_skills":["mermaid","excalidraw","plantuml"]},"author":"Agents365-ai","version":"3.3.0","homepage":"https://github.com/Agents365-ai/drawio-skill","compatibility":"Core IR, XML, sync, query, test, review, and Story workflows need Python 3 only; native export needs draw.io; Graphviz is optional.","platforms":["macos","linux","windows"]} --- # 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` | | 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` | | Shape, cloud/vendor, AI, or Databricks icon | Read `references/shapes.md` or `references/databricks.md`; never guess shape names | | Learn/apply/manage a visual style | Read `references/style-presets.md` | | Extract a reusable style from an existing diagram or theme | Read `references/style-extraction.md` | | Existing image to editable diagram (screenshot, whiteboard photo, legacy PNG) | Read `references/derasterize.md` | | Export/platform problem | Read `references/troubleshooting.md`; for access/network questions read `references/security.md` | ## Unified CLI Run from this skill directory, or replace `scripts/` with the absolute path to this skill's scripts directory: ```bash python3 scripts/diagramctl.py doctor python3 scripts/diagramctl.py build model.json --from ir -o architecture.drawio python3 scripts/diagramctl.py build ./infra --from terraform --group \ --ir-output architecture.ir.json -o architecture.drawio python3 scripts/diagramctl.py sync architecture.drawio ./infra --from terraform \ -o architecture.next.drawio python3 scripts/diagramctl.py views architecture.ir.json \ --views executive,system,deployment,dataflow,security -o views.drawio python3 scripts/diagramctl.py test architecture.drawio --rules policy.yml python3 scripts/diagramctl.py review architecture.drawio -o review.md python3 scripts/diagramctl.py query architecture.drawio --from internet --to orders-db python3 scripts/diagramctl.py whatif architecture.ir.json --fail kafka \ --drawio kafka-failure.drawio -o impact.json python3 scripts/diagramctl.py story architecture.ir.json -o walkthrough.html ``` `doctor` does not launch GUI tools unless `--probe` is passed. Core semantic commands are offline and stdlib-only. ## Creation workflow 1. Infer the diagram type, audience, scope, output format, and location from the request. Ask only when a missing choice materially changes the result; default to PNG plus `.drawio` in the working directory. 2. Select the authoring route from the table above. For a data-backed diagram, prefer Diagram IR and preserve provenance. For a large graph, use an importer or `autolayout.py`; do not hand-place more than roughly fifteen nodes. 3. Resolve an explicitly named style preset, or the user's default preset, as documented in `references/style-presets.md`. Structural diagram conventions and visual presets compose; they do not replace each other. 4. Generate the `.drawio`, then run structural validation: ```bash python3 scripts/validate.py diagram.drawio --score ``` When semantic metadata or an architecture policy is in scope, also run `diagramctl.py test`. Do not present inferred semantic findings as verified runtime facts. 5. Export a draft PNG without embedded XML and inspect it visually. Fix obvious overlap, clipping, disconnected edges, edge-through-node routing, stacked edges, and unreadable labels. Stop automatic vision repair after two rounds. 6. Show the draft and apply targeted edits. Preserve existing geometry for local changes. Use `sync` for source-backed changes and write a reviewable output; use `--prune` only when deletion was requested. 7. After approval, create final requested formats and report both editable source and export paths. ## Export invariants Resolve the available binary once (`drawio`, `draw.io`, the macOS app path, or the Windows executable) and use that exact binary for the run. ```bash # Draft for visual inspection: never use -e here drawio -x -f png --width 2000 -o diagram.png diagram.drawio # Final editable PNG drawio -x -f png -e -s 2 -o diagram.drawio.png diagram.drawio python3 scripts/repair_png.py diagram.drawio.png # Final editable SVG/PDF drawio -x -f svg -e --embed-svg-images -o diagram.svg diagram.drawio drawio -x -f pdf -e -o diagram.pdf diagram.drawio ``` Do not combine `--width` and `-s`. Embedded PNG exports require `repair_png.py`; draft PNGs used by vision must not use `-e`. On Linux headless, follow `references/troubleshooting.md` rather than improvising Electron flags. If the CLI crashes in a macOS sandbox, try one permitted escalated run, then use `encode_drawio_url.py` or deliver XML; do not repeatedly launch it. ## Editing and identity - Use stable semantic IDs and never reuse reserved IDs `0` or `1`. - Every edge requires `<mxGeometry relative="1" as="geometry"/>`. - For a local edit, change the matching cell only; for a global direction change, regenerate/re-layout the page. - Keep provenance, `data-model-id`, semantic properties, manual geometry, and manual styles intact unless the user requests otherwise. - When reconciling, retain removals as reviewable faded elements by default. - For edges stacked at a boundary, run `edgeports.py`; add waypoints when an edge still crosses an unrelated shape. There is no CLI-only edge rerouter that preserves node positions. ## Quality and trust An attractive diagram can still be wrong. Prefer source-backed relationships, show provenance where useful, distinguish exact extraction from AI inference, and keep architecture review findings framed as prompts. Story HTML must remain self-contained, keyboard usable, and include a text alternative. Never include secrets in node properties or provenance because they are embedded in outputs. For all focused scripts and composition patterns, read `references/toolbox.md`; load only the task-specific reference needed for the current request.
