| Feature | Native agent | This skill |
|---|---|---|
| Generate draw.io XML | Yes — LLMs know the format | Yes |
| Self-check after export | No | Yes — reads PNG and auto-fixes 6 issue types |
| Iterative review loop | No — must manually re-prompt | Yes — targeted edits, 5-round safety valve |
| Proactive triggers | No — only when explicitly asked | Yes — auto-suggests when 3+ components |
| Layout guidelines | None — varies by run | Complexity-scaled spacing, routing corridors, hub placement |
| Grid alignment | No | Yes — all coordinates snap to 10px multiples |
| Diagram type presets | No | Yes — 11 presets (ERD, UML Class, Sequence, C4, Architecture, ML/Deep Learning, Flowchart, SysML, BPMN, Network Topology, Cross-Functional Swimlane) |
| Visualize a codebase | No | Yes — import graphs (Py/JS/Go/Rust) + class diagrams |
| Auto-layout for large graphs | No — hand-places, overlaps | Yes — Graphviz placement, ortho routing, nested containers |
| Structural validation | No | Yes — deterministic .drawio linter |
| Official shape search | No — guesses, blank boxes | Yes — exact style for 10k+ AWS/Azure/GCP/UML shapes |
| AI/LLM brand logos | No — none | Yes — 321 logos (OpenAI/Claude/Gemini/…) via aiicons.py |
| Animated connectors | No | Yes — flowAnimation=1 for data-flow visualization |
| ML model diagrams | No | Yes — tensor shape annotations, layer-type color coding |
| Color palette | Random/inconsistent | 7-color semantic system (blue=services, green=DB, purple=auth...) |
| Edge routing rules | Basic | Pin entry/exit points, distribute connections, waypoint corridors |
| Container/group patterns | None | Swimlane, group, custom container with parent-child nesting |
| Embed diagram in export | No | Yes — --embed-diagram keeps exported PNG/SVG/PDF editable |
| Browser fallback | No | Yes — generates diagrams.net URL when CLI unavailable |
| Auto-launch desktop app | No | Yes — opens .drawio file after export for fine-tuning |

- Self-check + iterative loop — the only pure-SKILL.md solution that reads its own output and auto-fixes before showing the user, then supports multi-round refinement
- 11 diagram type presets — ERD, UML Class, Sequence, C4, Architecture, ML/Deep Learning, Flowchart, SysML, BPMN, Network Topology, Cross-Functional Swimlane — each with preset shapes, styles, and layout conventions
- ML/DL model diagrams — tensor shape annotations, layer-type color coding, encoder/decoder swimlanes — built for academic papers
- Multi-agent, zero-config — works across 6 platforms with just the
skills/drawio-skill/directory + draw.io desktop. No MCP server, no Python, no Node.js, no browser - Production-grade layout — grid-aligned coordinates, complexity-scaled spacing, routing corridors, hub-center strategy, animated connectors
- Browser fallback — generates diagrams.net URLs when the desktop CLI is unavailable, plus auto-launch for desktop editing
