🔧 MCP Tools

1. get_available_tasks

Query tasks ready for an agent to claim.

Input:

{
  "agent": "A",
  "includeDetails": true
}

Output:

{
  "agent": "A",
  "availableTasks": 2,
  "tasks": [
    {
      "id": "T004",
      "name": "Grid System Foundation",

      "dependencies": [],
      "deliverables": ["GridContainer.tsx", "types.ts"]
    }
  ]
}

2. claim_task

Atomically claim a task (prevents conflicts).

Input:

{
  "taskId": "T009",
  "agent": "A"
}

}

3. update_task_progress ⭐ NEW

Real-time progress tracking with file verification.

Input:

{
  "taskId": "T009",
  "agent": "A",
  "status": "IN_PROGRESS",
  "filesCreated": ["sidebar/Sidebar.tsx", "sidebar/types.ts"],
  "completionPercent": 65,
  "notes": "Implementing IPC integration"
}

Output:

{
  "success": true,
  "taskId": "T009",
  "progress": {
    "status": "IN_PROGRESS",
    "completionPercent": 65,
    "filesTracked": 2,
    "autoVerified": false
  },
  "tracking": {
    "gitCommits": 3,
    "filesFound": 2,
    "filesMissing": 0
  }
}

4. complete_task ⭐ ENHANCED

Complete task with automatic git verification and dependency unblocking.

Input:

{
  "taskId": "T009",
  "agent": "A",
  "filesCreated": [
    "sidebar/Sidebar.tsx",
    "sidebar/types.ts",
    "sidebar/SidebarDemo.tsx"
  ],
  "velocity": 640,
  "requireVerification": true
}

Output:

{
  "success": true,
  "taskId": "T009",
  "agent": "A",
  "velocity": 640,
  "verification": {
    "autoVerified": true,
    "completionScore": 100,
    "filesVerified": 3,
    "gitCommits": 5
  },
  "unblocked": {
    "count": 1,
    "tasks": ["T011"]
  },
  "message": "✅ Task T009 completed by Agent A",
  "impact": "🔓 Auto-unblocked 1 dependent task(s): T011"
}

📊 Git Verification System

How It Works

1. Agent Claims Task → Task status becomes CLAIMED
2. Agent Updates Progress → Real-time file tracking via git
3. Agent Completes Task → Automatic verification:
   • ✅ Check all deliverables exist
   • ✅ Verify files are committed to git
   • ✅ Calculate completion score (0-100)
   • ✅ Auto-unblock dependent tasks

Verification Scoring

Score = (Files Found / Files Expected) × 70 + (Git Commits > 0) × 30

100 = Perfect completion (all files + commits)
80+ = Auto-verified (task automatically marked complete)
<80 = Needs review (manual verification required)

File Tracking

// Automatic git tracking for each file
{
  path: "sidebar/Sidebar.tsx",
  created: "2025-10-08T15:30:00Z",
  modified: "2025-10-08T18:00:00Z",
  gitHash: "90fce086",
  size: 12345
}
