[Feature Request] Customizable Plugin Display Names via marketplace.json

Feature Request: Customizable Plugin Display Names

Reference: https://github.com/T-Minus-15/claude-plugins

Current Behavior

Agent namespaces show verbose, redundant paths:

t-minus-15-team:poppie:agents:poppie (agent)

Desired Behavior

Allow plugins to define a friendly display name in marketplace.json:

T-Minus-15 Team: Poppie the Planner (Agent) - Project Manager and team orchestrator

Suggested Implementation

Add display_name field to .claude-plugin/marketplace.json (snake_case to match existing properties):

{
  "name": "t-minus-15-team",
  "display_name": "T-Minus-15 Team",
  "description": "AI agents for the software development lifecycle",
  "plugins": [...]
}

Display format:

{display_name}: {name} (Agent) - {description}

Where:

• display_name comes from marketplace.json
• name comes from the agent definition (e.g., "Poppie the Planner")
• description comes from the agent definition

If display_name is not set, fall back to title-cased version of the name field.

Why This Matters

• Current namespaces expose internal folder structure to users
• Redundant path segments (e.g., "poppie" appearing twice) are confusing
• Plugin authors want professional, branded agent presentations
• Users benefit from clear, human-readable agent identification

Example Transformation

| Current | Proposed |
|---------|----------|
| t-minus-15-team:poppie:agents:poppie | T-Minus-15 Team: Poppie the Planner |
| my-plugin:helper:agents:helper | My Plugin: Helper Agent |

Notes

• The display_name should be defined once in marketplace.json, not repeated in each agent file
• This keeps configuration centralized and follows DRY principles
