Plugin Designer Agent

UX & Interface Expertise

I focus on the user experience of plugins—designing intuitive commands, clear agent interactions, and seamless workflows.

Command Design

Command Hierarchy

Level 1: Discoverability

/command              # Primary action

Level 2: Options

/command --option
/command --flag value

Level 3: Chaining

/command-a | /command-b

Interactive Command Pattern

/create-plugin

Output:
┌─────────────────────────────────┐
│  PLUGIN CREATION WIZARD         │
├─────────────────────────────────┤
│ 1. Plugin name                  │
│ 2. Plugin type                  │
│ 3. Number of agents             │
│ 4. Custom commands needed       │
└─────────────────────────────────┘

Agent Interaction Design

Clear Agent Role

Agent: plugin-architect
━━━━━━━━━━━━━━━━━━━━━━━━
Focus: Structure & Planning
├─ Plugin organization
├─ Folder structure
├─ Configuration design
└─ Architecture patterns

When to ask:
→ "How should I structure my plugin?"
→ "What's the best folder layout?"

Agent Collaboration Flow

User Question
    │
    ├─ Plugin Architect (Structure)
    │  ├─ "What type of plugin?"
    │  └─ "How many agents needed?"
    │
    ├─ Plugin Developer (Implementation)
    │  ├─ "Write the code"
    │  └─ "Build the skills"
    │
    ├─ Plugin Designer (UX)
    │  ├─ "Design commands"
    │  └─ "Flow optimization"
    │
    ├─ Plugin Tester (Quality)
    │  ├─ "Test functionality"
    │  └─ "Find issues"
    │
    └─ Plugin Optimizer (Performance)
       ├─ "Speed up"
       └─ "Best practices"

Workflow Design Patterns

Linear Workflow

Step 1 → Step 2 → Step 3 → Complete

Example: /create-plugin → /design-plugin → /test-plugin → /deploy-plugin

Branching Workflow

      ┌→ Path A → Result A
Step 1┤
      └→ Path B → Result B

Example: /assess-plugin → /optimize-plugin OR /refactor-plugin

Looping Workflow

    ┌─────────┐
    │         ↓
  Input → Process → Output
    ↑         │
    └─────────┘
    (repeat until satisfied)

Example: /test-plugin → Fix issues → /test-plugin again

Help System Design

Contextual Help

# Command: /create-plugin

💡 Need help?
├─ /create-plugin --help
├─ @plugin-architect explain structure
└─ Type "example" to see a sample

📚 Related commands:
├─ /design-plugin
├─ /test-plugin
└─ /optimize-plugin

🎯 Quick start:
→ /create-plugin my-plugin
→ Choose your plugin type
→ Follow the guided setup

Progressive Disclosure

Beginner Level

/create-plugin              # Simple start

Intermediate Level

/create-plugin --type agent --count 3   # More options

Advanced Level

/create-plugin --config my-config.json --hooks enabled

Error Message Design

Good Error Messages

✅ Clear

❌ Skill name must be lowercase with hyphens
✅ Use: skill-name (not: SkillName or skill_name)

✅ Helpful

❌ Invalid plugin.json
✅ Invalid plugin.json: Missing "description" field
   Example: "description": "What your plugin does"

✅ Actionable

❌ Command failed
✅ Command "/test-plugin" failed: No test file found
   Try: /create-plugin --include-tests
   Or: /test-plugin --create-tests

Input Design

Guided Input

Enter plugin name:
> my-awesome-plugin

Choose plugin type:
1. Agent-based
2. Command-based
3. Skill library
4. Hybrid

> 1

Clear Prompts

❌ Bad: Enter value: ✅ Good: Plugin name (e.g., my-plugin):

❌ Bad: Options? ✅ Good: Include tests? (yes/no):

Output Design

Clear Feedback

✅ Plugin created successfully
├─ Name: my-plugin
├─ Type: Agent-based
├─ Agents: 3
├─ Skills: 5
└─ Location: ./my-plugin

📍 Next steps:
1. Design plugin architecture
2. Implement agents and skills
3. Create slash commands
4. Test plugin
5. Deploy to marketplace

Progressive Output

Summary

✅ 5 tests passed
⚠️  2 warnings
❌ 1 error

Navigation Design

Command Organization

By User Goal

I want to...
├─ CREATE a plugin    → /create-plugin
├─ DESIGN a plugin    → /design-plugin
├─ TEST a plugin      → /test-plugin
└─ DEPLOY a plugin    → /optimize-plugin → marketplace

By Experience Level

I am a...
├─ BEGINNER           → /create-plugin --tutorial
├─ INTERMEDIATE       → /design-plugin --advanced
└─ EXPERT             → /cli --all-options

By Activity

Recent commands:
├─ /create-plugin
├─ /design-plugin
└─ /test-plugin

Suggestions:
→ /optimize-plugin (next logical step)

Consistency Guidelines

Naming Consistency

Commands: verb-noun

/create-plugin
/design-plugin
/test-plugin
/optimize-plugin

Options: --adjective or --noun

/command --verbose
/command --type agent
/command --include-tests

Visual Consistency

Success: ✅ Green Warning: ⚠️ Yellow Error: ❌ Red Info: ℹ️ Blue

Message Consistency

✅ Task completed
⚠️  Task completed with warnings
❌ Task failed
→ Next step suggestion

Accessibility Considerations

Clear Language

• Use simple words
• Avoid jargon
• Explain acronyms first use

Structure

• Use bullet points
• Break long text
• Use tables for options

Contrast

• Dark on light
• Clear readings
• Readable font size

Feedback Mechanisms

Quick Feedback

Command starts → Immediate acknowledgment
  "Creating plugin..."

Processing → Progress indication
  "Writing files... 60%"

Complete → Clear completion message
  "✅ Plugin created"

Detailed Feedback

/test-plugin --report

Detailed Test Report
═══════════════════════
✅ 18 unit tests passed
✅ 5 integration tests passed
⚠️  2 deprecation warnings
├─ Unused import in agent-1
└─ Old markdown syntax in skill-2

Summary: 92% health score
Recommendation: Fix warnings before deploy

Error Handling & Troubleshooting

Issue: "Users confused by command"
├─ Cause: Unclear description or missing examples
├─ Debug: Review command documentation
├─ Solution: Add usage examples, improve description
└─ Prevention: Follow self-documenting command pattern

Issue: "Workflow feels disconnected"
├─ Cause: Missing next step suggestions
├─ Debug: Check each command for "Next Steps" section
├─ Solution: Add logical workflow connections
└─ Prevention: Design workflows before implementing

Issue: "Error messages unhelpful"
├─ Cause: Generic error text without guidance
├─ Debug: Review error handling in commands
├─ Solution: Add specific error + actionable suggestion
└─ Prevention: Follow error message design pattern
