Task Router
Distributed task queue for OpenClaw multi-agent systems. Central coordination, async handoffs, capability-based routing.
Quick Start
# Install skill
clawhub install task-router
# Register an agent
task agent register watson --capabilities "research analysis" --max-concurrent 3
# Create a task
task create --type research --title "Competitor analysis" --priority high
# Router runs automatically via heartbeat
# Check task status
task list --status pending
task show task-abc123
What This Does
Core Functions:
- Enqueue: Create tasks from any session (main or sub-agent)
- Route: Match tasks to agents by capabilities
- Track: Monitor task lifecycle (pending → active → complete/failed)
- Async Coordination: Hand off work, check back later
- Dead Letter: Handle timeouts and failures
- Rebalance: Move stuck tasks, retry with fallbacks
- Heartbeat creates research task → auto-routes to research agent
- Main agent spawns work → goes async, checks later
- Multi-step workflows: Task A output → Task B input
- Agent failure → task reassigned to backup agent
- Load balancing across multiple agents with same capabilities

Programmatic API
import * as Task from "~/.openclaw/task-router/sdk";
// === Creating Tasks ===
// Simple create
const task = await Task.create({
type: "research",
title: "Competitor analysis",
payload: { query: "Gameye vs competitors" }
});
// With options
const task = await Task.create({
type: "image_gen",
title: "Generate hero image",
payload: { prompt: "Futuristic game server...", size: "1024x1024" },
priority: "high",
ttl: 1800,
max_retries: 1,
dependencies: [previousTaskId], // Waits for these first
created_by: "main"
});
// === Querying ===
// Get status
const status = await Task.status(task.id);
// { id, status, assigned_to, created_at, expires_at }
// Wait for completion (blocking)
const result = await Task.wait(task.id, { timeout: 300, pollInterval: 5 });
// List with filters
const pending = await Task.query({
status: "pending",
type: "research",
priority: "high",
limit: 10
});
const myTasks = await Task.query({
created_by: "main",
status: ["assigned", "running"]
});
// === Agent Integration ===
// Agent picks up work (if auto-assign disabled)
await Task.claim({
agentId: "watson",
capableOf: "research",
limit: 1
});
// Complete task
await Task.complete(task.id, {
result_path: "~/agents/watson/memory/results/competitors.md",
summary: "Found 5 competitors: GameLift, Multiplay, Hathora, Edgegap, Agones",
metadata: { competitors_count: 5 }
});
// Fail task
await Task.fail(task.id, {
reason: "API quota exceeded",
retryable: true // Will auto-retry
});
// === Multi-Step Workflows ===
// Chain tasks
const analysisTask = await Task.chain(researchTask.id, {
type: "analysis",
title: "Analyze research findings",
payload: { input_task: researchTask.id }
});
// Parallel tasks
const tasks = await Task.parallel([
{ type: "research", title: "Research A", payload: {} },
{ type: "research", title: "Research B", payload: {} },
{ type: "research", title: "Research C", payload: {} }
]);
await Task.waitAll(tasks.map(t => t.id));
// === Agent Session Integration ===
// Spawn via task router (recommended for async work)
const spawnResult = await Task.spawn({
taskId: task.id,
agentId: "watson", // Optional: auto-route if omitted
useSession: true // Use sessions_spawn vs sessions_send
});
// Router will call:
// sessions_spawn({ agentId, task, label: task.id })
HEARTBEAT Integration
Create ~/.openclaw/workspace/HEARTBEAT.md:
# Task Router Heartbeat
## Router Cycle (runs every 30s)
// 1. Auto-route pending tasks
const routed = await Task.router.cycle();
if (routed.length > 0) {
Task.log(Routed ${routed.length} tasks:, routed.map(t => ${t.id} → ${t.assigned_to}));
}
// 2. Check for timeouts
const timeouts = await Task.router.checkTimeouts();
for (const task of timeouts) {
if (task.retries < task.max_retries) {
Task.log(Retrying ${task.id} after timeout);
await Task.retry(task.id);
} else {
Task.log(Dead lettering ${task.id});
await Task.router.moveToDeadLetter(task);
}
}
// 3. Check agent health const unhealthy = await Task.agents.checkHealth(); for (const agent of unhealthy) { // Reassign their tasks await Task.router.reassignFrom(agent.id); }
// 4. Notify on completions
const recent = await Task.query({
status: "completed",
completed_after: Date.now() - 60000 // Last minute
});
for (const task of recent) {
if (task.created_by === "main") {
sessions_send({
message: ✅ Task complete: ${task.title}\nResult: ${task.result}
});
}
}
## Routing Strategies
| Strategy | Use Case | Description |
|----------|----------|-------------|
| **round-robin** | Even load | Cycle through agents |
| **least-loaded** | Prevent overload | Agent with fewest active tasks |
| **fastest** | Latency critical | Agent with best completion time |
| **priority** | Urgent tasks | Sort by priority first |
| **sticky** | Sequential work | Same agent for related tasks |
config.yaml
strategies: default: least-loaded # Per-task-type strategies by_type: research: least-loaded # Don't overwhelm one researcher image_gen: round-robin # Even GPU utilization urgent: priority # Always pick best agent # Custom rules rules:- if: priority == urgent
- if: tags includes "sticky"
## Task Lifecycle Details
**State Definitions:**
- `pending`: Created, waiting for router
- `assigned`: Routed to agent, waiting for acceptance
- `running`: Agent acknowledged, working on it
- `complete`: Success, result available
- `failed`: Final failure (retries exhausted)
- `dead_letter`: Failed permanently, needs manual review
## Dead Letter Queue
When a task exhausts retries:
Review failed tasks
task dead-letter list task dead-letter show task-failed-001Actions
task dead-letter retry task-failed-001 # Force retry task dead-letter reassign task-failed-001 --to watson task dead-letter archive task-failed-001 # Ack and archive## Best Practices
**Task Design:**
- Keep payloads JSON-serializable (no circular refs)
- Include output format hints in payload
- Use dependencies for true sequencing
- Set reasonable TTLs (don't block forever)
**Agent Design:**
- Register capabilities narrowly at first
- Set conservative max_concurrent
- Heartbeat should check for assigned tasks
- Always acknowledge → complete/fail cleanly
**Coordination Patterns:**
- Use `Task.spawn()` for fire-and-forget
- Use `Task.wait()` when user needs result now
- Chain dependent tasks vs one mega-task
- Let router handle retries, not agents
## Multi-Agent Example
// Main agent (you) orchestrates:
// 1. Create research tasks const research = await Task.create({ type: "research", title: "Research Gameye competitors", payload: { query: "Gameye vs competitors" } });
// 2. Create analysis task (depends on research) const analysis = await Task.create({ type: "analysis", title: "Analyze competitive landscape", dependencies: [research.id], payload: { input_task: research.id } });
// 3. Create image task (independent, async) const images = await Task.parallel([ { type: "image_gen", title: "Competitor comparison chart", payload: {} }, { type: "image_gen", title: "Market positioning diagram", payload: {} } ]);
// 4. Create presentation task (depends on all above) const deck = await Task.create({ type: "presentation", title: "Gameye competitive analysis deck", dependencies: [analysis.id, ...images.map(i => i.id)], payload: { research: analysis.id, images: images.map(i => i.result) } });
// 5. Wait for final result const result = await Task.wait(deck.id, { timeout: 600 });
// Result: orchestrated 4 agents, 5 tasks, handled dependencies
## Troubleshooting
Nothing routing?
task router status # Check paused? task agent list # Any healthy agents? task list --status pending # Tasks waiting?Task stuck?
task show task-abc123 # Check assigned_to, started_at task agent status watson # Is agent healthy?Agent not picking up?
- Check agent's HEARTBEAT checks for tasks
- Verify sessions_send to agent works
Too many failures?
task dead-letter list # Review patterns task router logs # See routing decisionsClear everything (nuke)
task router drain # Wait for active task list --status pending | xargs task cancel task dead-letter clear ```Requirements
- OpenClaw with sessions_send/sessions_spawn/sessions_list
- Agents with proper HEARTBEAT.md checking for tasks
- Optional: cron job for router if heartbeat not reliable

- Metrics: Prometheus-compatible stats
