MCPB Bundle, Verbose Loop Mode & Task Metadata

Minor Changes

• #1599 e689fcf Thanks @triepod-ai! - Add MCPB bundle for single-click Claude Desktop installation

  • Added manifest.json for MCP Bundle (MCPB) specification v0.3
  • Added .mcpbignore to exclude development files from bundle
  • Added icon.png (512x512) for Claude Desktop display
  • Enables users to install Task Master MCP server directly in Claude Desktop without manual configuration

• #1605 efedc85 Thanks @Crunchyman-ralph! - Add verbose output mode to loop command with --verbose flag

  • New -v, --verbose flag shows Claude's work in real-time (thinking, tool calls) rather than waiting until the iteration completes
  • New --no-output flag excludes full Claude output from iteration results to save memory
  • Improved error handling with proper validation for incompatible options (verbose + sandbox)

• #1611 c798639 Thanks @Crunchyman-ralph! - Add optional metadata field to tasks for storing user-defined custom data

  Tasks and subtasks now support an optional metadata field that allows storing arbitrary JSON data such as:

  • External IDs (GitHub issues, Jira tickets, Linear issues)
  • Workflow data (sprints, story points, custom statuses)
  • Integration data (sync timestamps, external system references)
  • Custom tracking (UUIDs, version numbers, audit information)

  Key features:

  • AI-Safe: Metadata is preserved through all AI operations (update-task, expand, etc.) because AI schemas intentionally exclude this field
  • Flexible Schema: Store any JSON-serializable data without schema changes
  • Backward Compatible: The field is optional; existing tasks work without modification
  • Subtask Support: Both tasks and subtasks can have their own metadata
  • MCP Tool Support: Use update_task and update_subtask with the metadata parameter to update metadata (requires TASK_MASTER_ALLOW_METADATA_UPDATES=true in MCP server environment)

  Example usage:

  {
    "id": 1,
    "title": "Implement authentication",
    "metadata": {
      "githubIssue": 42,
      "sprint": "Q1-S3",
      "storyPoints": 5
    }
  }
