Draw.io Diagram Forge

Generate draw.io editable diagrams using AI-powered workflow.

When to Use

• Creating architecture diagrams (Azure, AWS)
• Converting flowcharts from text descriptions
• Transforming images/screenshots into editable format
• Generating swimlane, sequence diagrams
• Editing Azure/AWS icons in existing .drawio files

Choose this skill when the result will need later GUI editing in draw.io, cloud icons, or documentation-facing diagram assets.

When NOT to Use

• Quick inline diagrams that are easier to keep as Mermaid in README or Markdown
• One-off text-native diagrams where manual GUI adjustment is not expected
• Charts or infographics that require exact axes, data binding, typography, or scripted regeneration
• Large multilingual label sets whose font rendering must be identical across platforms
• Interactive or animated HTML diagrams, or Mermaid beautification (out of scope)

Prerequisites

Quick Start

Create a login flow diagram

Generate an Azure Hub-Spoke architecture diagram

From inputs/requirements.md, create a system diagram

Output Formats

Output: outputs/

If the user asks for an editable diagram, make *.drawio the primary deliverable. Do not let a plain SVG or preview artifact become the file the user is expected to edit.

Recommended Delivery Pattern

ドキュメント向けは name.drawio (editable) + name.drawio.svg (embed) を対で出す。多言語変体・Qiita への掲載・ローカル preview 脱出手順は → references/delivery-patterns.md。

Workflow

Treat generated images as optional layout references, not requirement evidence. Resolve labels, nodes, groups and edge directions in the manifest; flag ambiguity instead of inventing content. Rebuild native mxCells and connectors; wrapping a raster image in draw.io metadata does not make its elements editable.

USER INPUT → ORCHESTRATOR → MANIFEST GATEWAY → SVG FORGE → COMPLETED

Quality Gates

When the deliverable is headed for print, gate it on the Monochrome Print Profile and the Pre-delivery Geometry Sweep in style-guide.md before any visual review.

Limits

Cloud Icons

Use Cloud Icons Reference. Azure diagrams must use verified img/lib/azure2/**/*.svg image paths, retain short service labels, and fall back to neutral boxes only when an icon is missing or misleading.

Done Criteria

• .drawio or .drawio.svg file generated
• Diagram opens correctly in VS Code Draw.io extension
• If an editable .drawio.svg is part of the delivery, it was exported with --embed-diagram and contains mxfile
• All nodes and edges visible
• User-facing links point to the editable .drawio when editability is expected
• Decision flows avoid long return/merge lines that bundle branch outputs back into one sink
• Quality gate score ≥ 85
• If diagram is referenced from documentation, both editable source and embeddable image are provided
• Render review completed at the target embed width: no text overlap, clipping, or border collisions, no edges overlapping on one line, no edge endpoint buried inside a filled box, no label riding on a box or another label, no node outside the page
• After any edge or label layout change, re-export the delivery asset for the target medium (SVG for web, PNG or the final PDF for print) and inspect it; structural validation alone does not prove visual routing quality
