Visual Architecture with Auto-Generated Mermaid Diagrams
Diagrams

A picture is worth a thousand lines of code. When you're discussing complex system migrations, database schemas, or authentication flows, text description often falls short. ClarityAI bridges this gap by integrating Mermaid.js directly into your expansion workflow, turning abstract logic into concrete visual roadmaps. This feature is a game-changer for collaboration and architectural clarity.

The Documentation Decay Problem

Diagrams are usually the first thing to go stale in a project. They are often created in external tools like Miro or Lucidchart, saved as PNGs, and buried in a Confluence page. When the code changes, the diagram doesn't. ClarityAI solves this by treating diagrams as "Code-Adjacent Artifacts." They are generated from the same prompt that generates the code, ensuring they are always in sync.

Automated Visual Context

ClarityAI's engine is trained to detect "Visualizable Intent." If your prompt includes keywords like "flow", "hierarchy", "database", or "design", the system automatically appends a requirement for a Mermaid.js diagram. This is much more than just asking for a picture; it's about providing a secondary conceptual model for the developer to verify.

The Integrated Visual Workspace

    Auto-Generation Engine

    No need to ask "can you draw a diagram?" ClarityAI knows when it's appropriate and forces the AI-agent to provide a Mermaid block. It supports Flowcharts, Sequence Diagrams, ER Diagrams, and Gantt charts.

    Real-time Preview Panel

    The diagrams are rendered using an optimized local engine inside the VS Code Chat UI. You can see your architecture evolve as you refine your prompt using the "Tweak" feature.

    Mermaid Live Sync

    Sometimes you need a full editor. Every diagram comes with an "Open in Mermaid Live" button that sends the generated markup to the official Mermaid editor with zero friction.

Example Render Flow

graph TD
    User([User Request: 'How does Auth work?']) --> Detect{Design-Related?}

    Prompt --> Gen[AI Generates Technical Specs + Mermaid Code]
    Gen --> Render[Local Rendering Engine]
    Render --> UI[Interactive VS Code Chat Panel]
    UI --> Live[One-click Export to Live Editor]

Pro Tip: Forcing Diagrams

If the auto-detection misses your intent, you can manually force a diagram by adding a simple directive to your .clarityrules file: "Always provide a Mermaid.js flowchart for logic involving process flows." This ensures consistency across your entire project.

This feature ensures that documentation and code stay in lock-step. When you use ClarityAI, you're not just getting code snippets; you're getting a full technical blueprint that the whole team can visualize and understand.
