Diagrams

Continue working on an existing diagram. Load, review, and modify persistent diagrams across sessions.

World-class creation of valid, beautiful, and accessible Mermaid diagrams. Use when users request diagrams, flowcharts, sequence diagrams, entity relationship diagrams, state machines, Gantt charts, class diagrams, or any visual representation that can be expressed in Mermaid syntax. Handles all Mermaid diagram types with expert knowledge of syntax, styling, and best practices.

This skill should be used when the user asks to "create a diagram", "draw a flowchart", "generate a sequence diagram", "make a state diagram", "create a class diagram", "draw an ER diagram", "update diagram", "edit mermaid", "improve diagram layout", or mentions mermaid diagrams in any context.

Creates and edits Mermaid diagrams for flowcharts, sequence diagrams, ERDs, state machines, architecture diagrams, process flows, timelines, and more. Use when user mentions diagram, flowchart, mermaid, visualize, refactor diagram, sequence diagram, ERD, architecture diagram, process flow, state machine, or needs visual documentation.

Generate publication-ready scientific figures for research papers.Use this skill when:- Creating any figures for manuscripts (Nature, Science, Cell quality)- Generating data plots from CSV/Excel/JSON datasets- Creating conceptual diagrams, flowcharts, or schematics- Composing multi-panel figures with letter labels (A, B, C, D)- Visualizing architectures, timelines, or workflowsThis skill handles THREE types of figures:1. DATA PLOTS - Line, scatter, bar, violin, heatmap, etc. from tabular data2. SCHEMATICS - AI-generated conceptual diagrams and illustrations3. COMPOSITIONS - Multi-panel figures combining plots and/or schematicsPrerequisites:- For plots: pandas, matplotlib, seaborn- For schematics: OPENROUTER_AI_API_KEY environment variable- For composition: matplotlib or PIL

Generate syntactically correct Mermaid diagrams for technical documentation

[UI/UX] Visualizes interaction sequences and system communications as ASCII diagrams. Represents user-system interactions, API call sequences, and event flows. Use when requesting 'sequence diagram', 'interaction flow', or 'API sequence'.

Debug WebSocket connection issues between CLI and FigJam plugin. Use when diagrams aren't syncing or connection fails.

Design scalable, reliable software systems. Use when planning new systems, major features, or architecture changes. Covers C4 diagrams, trade-off analysis, and system decomposition.

Enhance an existing PR by analyzing the diff against the description and updating with examples, diagrams, and context

Capture thinking visually during brainstorming, architecture discussions, or explaining flows. Creates persistent Mermaid diagrams.

Transform requirements into user journeys and flow diagrams. Use when designing user workflows, mapping customer journeys, or planning interaction sequences.

Creates Excalidraw diagrams programmatically. Use when the user wants flowcharts, architecture diagrams, system designs, or any visual diagram instead of ASCII art. Outputs .excalidraw files that can be opened directly in Excalidraw or VS Code with the Excalidraw extension.

Generates interactive code flow diagrams (.cgraph files). Invoke when users ask: "how does X work", "show me the flow of Y", "visualize the architecture", "diagram the data flow", "create a graph of the codebase", or similar queries about understanding code structure and relationships.

Generate photorealistic images with perfect text rendering using Nano Banana Pro (Gemini 3 Pro Image). Automatically enhances prompts for optimal results with this reasoning-based image model. Use when users request image generation, logos, infographics, posters, diagrams, or any visual content.

Explains code with visual diagrams and analogies. Use when explaining how code works, teaching about a codebase, or when the user asks "how does this work?"

Expert guidance for Mermaid.js diagramming library. Create flowcharts, sequence diagrams, class diagrams, state diagrams, Gantt charts, git graphs, and block diagrams. Use when working with Mermaid syntax, creating diagrams, or visualizing complex concepts and workflows.

Explain data flows, features, and code paths in the varun.surf application with visual diagrams and step-by-step breakdowns

Master process modeling with BPMN, flowcharts, swimlane diagrams, and process optimization techniques for business process improvement.

Maps complete data flows from UI components through API services, backend endpoints, Genkit flows, to database operations. Generates visual architecture diagrams.
