Mermaid

senior-architect is a Software Architecture skill for system design, ADRs, stack decisions, scalability reviews, dependency analysis, and architecture diagrams using included Python scripts and references.

diagram-generator helps create and edit draw.io, Mermaid, and Excalidraw diagrams from structured input. It supports flowcharts, sequence diagrams, class diagrams, ER diagrams, mind maps, architecture diagrams, and network topologies, and can read existing .drawio, .mmd, and Excalidraw files for easier updates.

The uml skill helps you create PlantUML diagrams for software modeling, including class, sequence, activity, state machine, component, use case, deployment, and related diagrams. Use uml for Diagramming when you need editable, auto-laid-out, text-first diagrams for code, docs, and repo workflows. Not suited for layered architecture, charts, or BPMN workflows.

archimate helps you create ArchiMate diagrams in PlantUML with `!include <archimate/Archimate>`, typed element macros, and relationship macros. It fits layered enterprise architecture views for business, application, technology, motivation, and migration planning. Use archimate for Diagramming when you need structured EA notation, not generic cloud or network diagrams.

bpmn helps you create business process and integration diagrams in PlantUML with BPMN, EIP, and Lean Mapping stencil icons. It is built for workflow automation, approvals, orchestration, messaging, ETL, and value stream mapping, with clear guidance on when to use bpmn and when to choose uml or vega instead.

markdown-mermaid-writing is a Markdown and Mermaid diagram writing skill for scientific and technical documentation. Use it to turn workflows, architectures, analyses, and reports into editable text-first docs with clear diagrams, version control friendliness, and practical markdown-mermaid-writing usage for Technical Writing.
