Bug: marketplace.json has invalid 'source' field - should be 'type'

[hendridg]

Problem

When trying to install the plugin via Claude Code marketplace:

claude plugin marketplace add Gentleman-Programming/engram

It fails with:

Failed to parse marketplace file at .claude-plugin/marketplace.json: Invalid schema: plugins.0.source: Invalid input

Root Cause

In .claude-plugin/marketplace.json, the source object on line 18 uses "source" as the key for the source type, but the schema likely expects "type":

Current (broken):

"source": {
  "source": "git-subdir",
  "url": "https://github.com/Gentleman-Programming/engram.git",
  "path": "plugin/claude-code"
}

Expected fix:

"source": {
  "type": "git-subdir",
  "url": "https://github.com/Gentleman-Programming/engram.git",
  "path": "plugin/claude-code"
}

Steps to Reproduce

1. Run claude plugin marketplace add Gentleman-Programming/engram
2. Observe the schema validation error on plugins.0.source

Environment

• Claude Code CLI
• macOS
