Installation Guide

How to use architecture-diagram-creator on Cursor

AI-first code editor with Composer

1

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

  • Cursor installed and configured on your machine
  • Node.js 16+ with npm — verify with node --version
  • Active project directory where you want to add architecture-diagram-creator
2

Run the install command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/mhattingpete/claude-skills-marketplace --skill architecture-diagram-creator

Fetches architecture-diagram-creator from mhattingpete/claude-skills-marketplace and configures it for Cursor.

3

Select Cursor when prompted

The CLI shows a list of agents. Use arrow keys and space to select Cursor:

◆ Which agents do you want to install to?
│ ── Universal (.agents/skills) ────────────────
│ · Cline · Codex · Goose · Windsurf
│ ●Cursor(selected)
│ · Cursor · Aider · Continue
4

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/architecture-diagram-creator

Restart Cursor to activate architecture-diagram-creator. Access via /architecture-diagram-creator in your agent's command palette.

Security Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Documentation

Architecture Diagram Creator

Create comprehensive HTML architecture diagrams with data flows, business context, and system architecture.

When to Use

  • "Create architecture diagram for [project]"
  • "Generate high-level overview"
  • "Document system architecture"
  • "Show data flow and processing pipeline"

Components to Include

  1. Business Context: objectives, users, value, metrics
  2. Data Flow: sources → processing → outputs with SVG diagram
  3. Processing Pipeline: multi-stage visualization
  4. System Architecture: layered components (data/processing/services/output)
  5. Features: functional and non-functional requirements
  6. Deployment: model, prerequisites, workflows

HTML Structure

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>[Project] Architecture</title>
  <style>
    body { font-family: system-ui; max-width: 1200px; margin: 0 auto; padding: 20px; }
    h1 { background: linear-gradient(135deg, #667eea 0%, #764ba2 100%); color: white; padding: 30px; }
    .section { margin: 30px 0; }
    svg { max-width: 100%; }
    /* Use semantic colors: #4299e1 (data), #ed8936 (processing), #9f7aea (AI), #48bb78 (success) */
  </style>
</head>
<body>
  <h1>[Project Name] - Architecture Overview</h1>

  <!-- Business Context Section -->
  <!-- Data Flow Diagram (SVG) -->
  <!-- Processing Pipeline (SVG) -->
  <!-- System Architecture Layers -->
  <!-- Features Grid -->
  <!-- Deployment Info -->
</body>
</html>

SVG Pattern for Data Flow

<svg viewBox="0 0 800 400">
  <!-- Data sources (left, blue) -->
  <rect x="50" y="150" width="120" height="80" fill="#4299e1"/>

  <!-- Processing (center, orange) -->
  <rect x="340" y="150" width="120" height="80" fill="#ed8936"/>

  <!-- Outputs (right, green) -->
  <rect x="630" y="150" width="120" height="80" fill="#48bb78"/>

  <!-- Arrows connecting -->
  <path d="M170,190 L340,190" stroke="#666" stroke-width="2" marker-end="url(#arrow)"/>
</svg>

Workflow

  1. Analyze project (README, code structure)
  2. Extract: purpose, data sources, processing, tech stack, outputs
  3. Create HTML with all 6 sections
  4. Use semantic colors for visual hierarchy
  5. Write to [project]-architecture.html

Keep diagrams clear, use consistent styling, include real project details.

Use Cases

User Story & Requirements Generation

Create detailed user stories, acceptance criteria, and feature specs

Example

Generate user stories for 'password reset feature' with acceptance criteria, edge cases, and test scenarios

Reduce spec writing time by 50%, ensure comprehensive coverage

Competitive Analysis

Research competitors, compare features, identify gaps

Example

Analyze 5 competitor products, create feature comparison matrix, suggest differentiation opportunities

Complete competitive research in 2 hours instead of 2 days

Roadmap Prioritization

Evaluate features using frameworks (RICE, ICE, Kano) and create prioritized backlogs

Example

Score 20 feature ideas using RICE framework, generate prioritized roadmap with rationale

Make data-driven prioritization decisions faster

Stakeholder Communication

Draft PRDs, status updates, and stakeholder presentations

Example

Create executive summary of Q3 roadmap, monthly progress report, feature launch announcement

Save 3-5 hours/week on communication overhead

Implementation Guide

Prerequisites

  • Claude Desktop or compatible AI client
  • Access to product documentation and roadmap tools (Jira, Notion, etc.)
  • Understanding of product management frameworks (RICE, Jobs-to-be-Done, etc.)
  • Stakeholder contact information and communication channels

Time Estimate

30-60 minutes to see productivity improvements

Steps

  1. 1Install product management skill
  2. 2Start with user story generation for known feature
  3. 3Progress to competitive analysis: research 2-3 competitors
  4. 4Use for roadmap prioritization: apply RICE/ICE scoring
  5. 5Draft stakeholder communications and refine based on feedback
  6. 6Build template library for recurring PM tasks
  7. 7Share effective prompts with product team

Common Pitfalls

  • Not validating competitive research—verify facts before sharing
  • Accepting user stories without involving engineering team
  • Over-relying on frameworks without qualitative judgment
  • Not customizing outputs to company culture and communication style
  • Skipping stakeholder validation of generated requirements

Best Practices

✓ Do

  • +Validate research and competitive analysis with real data
  • +Collaborate with engineering when generating technical requirements
  • +Customize frameworks and templates to your company context
  • +Use skill for first drafts, refine with stakeholder input
  • +Document successful prompt patterns for PM tasks
  • +Combine AI efficiency with human judgment and intuition

✗ Don't

  • Don't publish competitive analysis without fact-checking
  • Don't finalize user stories without engineering review
  • Don't make prioritization decisions solely on AI scoring
  • Don't skip customer validation of generated requirements
  • Don't ignore company-specific context and culture

💡 Pro Tips

  • Provide context: company goals, constraints, customer feedback
  • Ask for alternatives: 'Show 3 ways to prioritize this roadmap'
  • Request stakeholder-specific formatting: 'Executive summary vs. engineering spec'
  • Use skill for 70% generation + 30% customization to company needs

When to Use This

✓ Use when

Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.

✗ Avoid when

Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.

Learning Path

  1. 1Basic: user stories, feature specs, status updates
  2. 2Intermediate: competitive analysis, prioritization frameworks, PRDs
  3. 3Advanced: product strategy, go-to-market planning, OKR setting
  4. 4Expert: product vision, market positioning, business model innovation
