drawio-skills

Workflows Overview

Draw.io Skill exposes three base routes and an academic overlay policy:

• /drawio create
• /drawio edit
• /drawio replicate
• /drawio-academic-skills for publication-facing variants of those routes

All routes share the same YAML-first model, design system, base CLI, and validation stack.

Shared Runtime Rules

1. Offline Authoring Path by default
2. Desktop-Enhanced Export when draw.io Desktop is available
3. Live Refinement Backend only for explicit base-skill browser refinement
4. Direct XML Exception only for tiny XML-only handoff or exact mxGraph control

The skill keeps final delivery directories focused on:

• <name>.drawio

Canonical sidecars such as <name>.spec.yaml and <name>.arch.json should live in a project-local work directory such as .drawio-tmp/<name>/ unless the user explicitly asks for a beside-output bundle. Academic overlay adds <name>.svg to the default publication final delivery set.

Route Comparison

Route	Primary input	Default output	When to use
create	Text, YAML, Mermaid, CSV	New .drawio plus work-dir sidecars	Build a new general diagram
edit	Existing bundle or .drawio file	Updated .drawio plus work-dir sidecars	Modify or restyle a diagram
replicate	Uploaded image or screenshot	Redrawn .drawio plus work-dir sidecars	Recreate a reference diagram
academic overlay	Paper/thesis/manuscript prompt	final .drawio + .svg, sidecars in work dir	Publication-ready figures

/drawio create

Use this for brand-new general diagrams.

Input modes

• Natural language
• YAML spec
• Mermaid
• CSV hierarchy / org-chart style input
• Existing .drawio import when paired with --input-format drawio

Fast path

The skill can skip clarification when the request already makes the type, theme, layout, and complexity clear.

Full path

The skill slows down and drafts the logic first when the request is:

• ambiguous
• dense
• stencil-heavy
• routing-sensitive
• a replication or major edit

Automatic branches

• Math / Formula: enforces official delimiters only
• Stencil-heavy: loads cloud and network icon guidance
• Edge audit: loads routing and label-clearance rules
• Academic trigger: use the sibling academic overlay when publication policy matters

See Creating Diagrams.

Academic Overlay

Use drawio-academic-skills for paper, thesis, IEEE, journal, manuscript, publication-ready, A4/Word/LaTeX, or formula-heavy scholarly figures.

The overlay performs academic preflight:

• venue or audience
• figureType: architecture, roadmap, or workflow
• monochrome vs color policy
• caption, title, and legend needs
• formula and text-position fidelity
• requested exports and Desktop availability

It then executes through sibling ../drawio/scripts/cli.js. It does not use MCP/live backend.

/drawio edit

Use this for incremental changes, imports, restructures, or theme switches.

Preferred edit targets

1. Existing offline bundle
2. Existing .drawio imported into a bundle
3. Live browser session only when explicitly requested for base-skill refinement

Common edit types

• rename labels
• add or remove nodes and edges
• switch themes
• change semantic types
• restructure modules
• move elements with grid-safe positions

See Editing Diagrams.

/drawio replicate

Use this to redraw an uploaded image into a structured spec.

Core replication steps

1. Analyze the diagram structure
2. Extract the source palette
3. Run a text-fidelity pass for labels, captions, formulas, and edge labels
4. Build a YAML spec
5. Present logic, palette, and text-placement summary when needed
6. Render final artifacts and work-dir sidecars

Text fidelity

Replication should preserve more than structure and color:

• keep standalone text, captions, legends, and formula annotations as first-class elements when their position matters;
• prefer explicit bounds for exact text boxes and formulas;
• use labelOffset to keep connector labels off the line instead of sitting on top of it;
• compare the source and export once for title, caption, callout, formula, and edge-label placement.

Color modes

Mode	Default	Effect
preserve-original	Yes	Preserve source palette with explicit style overrides
theme-first	No	Normalize the redraw to the selected theme

See Replicating Diagrams.

Shared Guardrails

Design system

• 6 built-in themes
• shared style presets in skills/drawio/styles/built-in/
• semantic node types
• typed connectors
• 8px grid defaults

Validation

• structure validation
• layout validation
• quality validation
• formula delimiter validation
• text-position validation for replication outputs

Strict mode

Use --strict or --strict-warnings when publication quality or release-grade review matters.
