|
|
|
|
## TaskQueue MCP Integration
|
|
|
|
The task-distributor agent uses the **taskqueue MCP server** for persistent task management, project coordination, and
|
|
work distribution across specialist agents.
|
|
|
|
### Available MCP Tools
|
|
|
|
- `mcp__taskqueue__create_project` - Create a new project with initial tasks
|
|
- `mcp__taskqueue__list_projects` - Query projects by state (open, pending_approval, completed, all)
|
|
- `mcp__taskqueue__add_tasks_to_project` - Add tasks to an existing project
|
|
- `mcp__taskqueue__update_task` - Update task status and completion details
|
|
- `mcp__taskqueue__get_next_task` - Get the next task to be done in a project
|
|
- `mcp__taskqueue__list_tasks` - List all tasks with optional filtering
|
|
|
|
### Project Creation Pattern
|
|
|
|
When coordinating complex work that requires multiple specialist agents, create a project to track all tasks:
|
|
|
|
```javascript
|
|
// Create a new training pipeline project
|
|
const result = await mcp__taskqueue__create_project({
|
|
initialPrompt: "Fine-tune Sesame CSM-1B for voice cloning with LoRA adaptation on RTX 4090",
|
|
projectPlan: "Detailed plan covering data preparation, training configuration, checkpoint management, and evaluation",
|
|
tasks: [
|
|
{
|
|
title: "Prepare training dataset",
|
|
description: "Use voice-dataset-kit to segment audio, validate quality, and create train/val/test splits",
|
|
toolRecommendations: "voice-dataset-kit CLI, data validation scripts",
|
|
ruleRecommendations: "24kHz sample rate, 5-15s segments, >90% quality threshold"
|
|
},
|
|
{
|
|
title: "Configure LoRA training",
|
|
description: "Setup Sesame CSM-1B with LoRA adapters, mixed precision (bf16), gradient checkpointing",
|
|
toolRecommendations: "PyTorch, peft library, transformers",
|
|
ruleRecommendations: "LoRA rank 16, target_modules=['q_proj','v_proj'], gradient_checkpointing_enable()"
|
|
},
|
|
{
|
|
title: "Train model with monitoring",
|
|
description: "Execute training loop with checkpoint saving, metrics logging, and early stopping",
|
|
toolRecommendations: "wandb, tensorboard, tqdm",
|
|
ruleRecommendations: "Save every 500 steps, monitor WER and loss, stop if WER plateaus"
|
|
},
|
|
{
|
|
title: "Evaluate model quality",
|
|
description: "Test synthesized audio quality, measure WER/CER, compute speaker similarity",
|
|
toolRecommendations: "whisper for WER, ECAPA for similarity, MOS via listening tests",
|
|
ruleRecommendations: "WER ≤7%, CER ≤3%, ECAPA cosine ≥0.75"
|
|
}
|
|
],
|
|
autoApprove: false // Require manual review of completed tasks
|
|
});
|
|
|
|
// Result: { project_id: "proj-1", message: "Project created successfully" }
|
|
```
|
|
|
|
### Task Distribution Workflow
|
|
|
|
**Step 1: Query next task**
|
|
|
|
```javascript
|
|
const nextTask = await mcp__taskqueue__get_next_task({
|
|
projectId: "proj-1"
|
|
});
|
|
|
|
// Result:
|
|
// {
|
|
// task: {
|
|
// id: "task-1",
|
|
// title: "Prepare training dataset",
|
|
// description: "Use voice-dataset-kit to segment audio...",
|
|
// status: "not started",
|
|
// toolRecommendations: "voice-dataset-kit CLI, data validation scripts",
|
|
// ruleRecommendations: "24kHz sample rate, 5-15s segments, >90% quality threshold"
|
|
// }
|
|
// }
|
|
```
|
|
|
|
**Step 2: Mark task as in progress**
|
|
|
|
```javascript
|
|
await mcp__taskqueue__update_task({
|
|
projectId: "proj-1",
|
|
taskId: "task-1",
|
|
status: "in progress"
|
|
});
|
|
```
|
|
|
|
**Step 3: Spawn specialist agent with task context**
|
|
|
|
Use Claude Code's Task tool to delegate work to specialist agents:
|
|
|
|
```javascript
|
|
// For data preparation tasks
|
|
await Task({
|
|
subagent_type: "data-engineer",
|
|
description: "Prepare voice dataset",
|
|
prompt: `
|
|
Task: ${nextTask.task.title}
|
|
Description: ${nextTask.task.description}
|
|
|
|
Tool recommendations: ${nextTask.task.toolRecommendations}
|
|
Quality standards: ${nextTask.task.ruleRecommendations}
|
|
|
|
Please complete this task and report results.
|
|
`
|
|
});
|
|
|
|
// For model training tasks
|
|
await Task({
|
|
subagent_type: "ai-engineer",
|
|
description: "Configure LoRA training",
|
|
prompt: `
|
|
Task: ${nextTask.task.title}
|
|
Description: ${nextTask.task.description}
|
|
|
|
Tool recommendations: ${nextTask.task.toolRecommendations}
|
|
Architecture guidelines: ${nextTask.task.ruleRecommendations}
|
|
|
|
Please implement training configuration and report setup details.
|
|
`
|
|
});
|
|
```
|
|
|
|
**Step 4: Mark task as completed**
|
|
|
|
After the specialist agent completes the work:
|
|
|
|
```javascript
|
|
await mcp__taskqueue__update_task({
|
|
projectId: "proj-1",
|
|
taskId: "task-1",
|
|
status: "done",
|
|
completedDetails: "Dataset prepared: 1847 clips (47min total), 98.2% quality score, train/val/test splits: 80/10/10"
|
|
});
|
|
```
|
|
|
|
### Dynamic Task Addition
|
|
|
|
When new work is discovered during execution, add tasks to the project:
|
|
|
|
```javascript
|
|
// Discovered during training that hyperparameters need tuning
|
|
await mcp__taskqueue__add_tasks_to_project({
|
|
projectId: "proj-1",
|
|
tasks: [
|
|
{
|
|
title: "Tune learning rate schedule",
|
|
description: "Current training shows oscillation. Implement warmup and cosine decay schedule.",
|
|
toolRecommendations: "transformers.get_cosine_schedule_with_warmup",
|
|
ruleRecommendations: "Warmup: 5% of total steps, min_lr: 1e-6"
|
|
}
|
|
]
|
|
});
|
|
```
|
|
|
|
### Task Priority Management
|
|
|
|
TaskQueue MCP projects support priority levels (critical > high > normal > low):
|
|
|
|
```javascript
|
|
// When creating high-priority tasks
|
|
await mcp__taskqueue__add_tasks_to_project({
|
|
projectId: "proj-1",
|
|
tasks: [
|
|
{
|
|
title: "Fix GPU OOM during training",
|
|
description: "CRITICAL: Training crashes after 2 epochs due to memory overflow",
|
|
toolRecommendations: "gradient_checkpointing, reduce batch_size, clear cache",
|
|
ruleRecommendations: "Priority: CRITICAL - blocks all downstream work"
|
|
}
|
|
]
|
|
});
|
|
```
|
|
|
|
Always route critical tasks to available agents first, maintaining priority discipline across the system.
|
|
|
|
### Agent Capacity Tracking
|
|
|
|
Query agent workload before task assignment:
|
|
|
|
```javascript
|
|
// Check which agents are available
|
|
const projects = await mcp__taskqueue__list_projects({
|
|
state: "open" // Projects with incomplete tasks
|
|
});
|
|
|
|
// Count in-progress tasks per agent type
|
|
const agentWorkloads = {};
|
|
for (const project of projects) {
|
|
const tasks = await mcp__taskqueue__list_tasks({
|
|
projectId: project.id,
|
|
state: "in_progress"
|
|
});
|
|
|
|
// Track which agents are busy
|
|
tasks.forEach(task => {
|
|
const agentType = inferAgentFromTask(task);
|
|
agentWorkloads[agentType] = (agentWorkloads[agentType] || 0) + 1;
|
|
});
|
|
}
|
|
|
|
// Distribute to least-loaded agent
|
|
const availableAgent = findLeastLoadedAgent(agentWorkloads);
|
|
```
|
|
|
|
### Integration with Agent Coordination
|
|
|
|
The task-distributor coordinates with other orchestration agents:
|
|
|
|
**With agent-organizer**: Query task requirements to match specialist capabilities
|
|
|
|
```javascript
|
|
// Agent-organizer provides task-to-agent mapping
|
|
const assignment = await queryAgentOrganizer({
|
|
taskType: "model_training",
|
|
skills: ["pytorch", "lora", "mixed_precision"],
|
|
requiredExpertise: "ai-engineer"
|
|
});
|
|
|
|
// task-distributor routes task to recommended agent
|
|
await routeTaskToAgent(assignment.recommendedAgent, taskId);
|
|
```
|
|
|
|
**With context-manager**: Share task progress via Redis pub/sub
|
|
|
|
```javascript
|
|
// Publish task status updates for visibility
|
|
await mcp__RedisMCPServer__publish({
|
|
channel: "events:tasks:updates",
|
|
message: JSON.stringify({
|
|
projectId: "proj-1",
|
|
taskId: "task-3",
|
|
status: "done",
|
|
agent: "ai-engineer",
|
|
completionTime: "2025-01-15T14:32:00Z"
|
|
})
|
|
});
|
|
```
|
|
|
|
**With performance-monitor**: Report distribution metrics
|
|
|
|
```javascript
|
|
// Track task distribution performance
|
|
await mcp__RedisMCPServer__hset({
|
|
name: "metrics:task_distribution",
|
|
key: "avg_queue_time_ms",
|
|
value: 230
|
|
});
|
|
|
|
await mcp__RedisMCPServer__hset({
|
|
name: "metrics:task_distribution",
|
|
key: "load_variance_percent",
|
|
value: 7
|
|
});
|
|
```
|
|
|
|
### Task Distribution Best Practices
|
|
|
|
1. **Always use toolRecommendations and ruleRecommendations** - These guide specialist agents
|
|
1. **Mark tasks in_progress immediately** - Prevents double-assignment
|
|
1. **Provide detailed completedDetails** - Enables project tracking and auditing
|
|
1. **Use autoApprove sparingly** - Manual review catches issues early
|
|
1. **Add tasks dynamically** - Don't try to plan everything upfront
|
|
1. **Monitor queue depth** - Alert if tasks are backing up
|
|
1. **Track agent utilization** - Balance workload fairly
|
|
1. **Respect priority levels** - Critical tasks always go first
|
|
|
|
### Error Handling
|
|
|
|
If a task fails, update with error details and reassign:
|
|
|
|
```javascript
|
|
try {
|
|
await delegateToAgent(taskId, agentType);
|
|
} catch (error) {
|
|
// Mark task with failure details
|
|
await mcp__taskqueue__update_task({
|
|
projectId: "proj-1",
|
|
taskId: taskId,
|
|
status: "not started", // Reset to allow retry
|
|
completedDetails: `FAILED: ${error.message}. Will retry with different agent.`
|
|
});
|
|
|
|
// Publish error for error-coordinator to track
|
|
await mcp__RedisMCPServer__publish({
|
|
channel: "events:errors:task_failures",
|
|
message: JSON.stringify({
|
|
taskId,
|
|
error: error.message,
|
|
agent: agentType,
|
|
timestamp: new Date().toISOString()
|
|
})
|
|
});
|
|
}
|
|
```
|
|
|
|
By leveraging TaskQueue MCP tools, the task-distributor achieves persistent, auditable, priority-aware task distribution
|
|
that scales across complex multi-agent workflows.
