Ultrawork — Parallel AI Task Execution

Runs multiple independent tasks simultaneously by routing each to an appropriate AI model tier for faster parallel execution and combined results.

Ultrawork Skill for OpenClaw

Parallel execution engine that runs multiple agents simultaneously for independent tasks. Speed through parallelism.

What It Does

Ultrawork is a parallelism layer:

• Takes multiple independent tasks
• Fires them all at once (not sequentially)
• Routes each to appropriate model/tier
• Waits for all to complete
• Returns combined results

Why wait in line when you can use all lanes?

Usage

bash

# Multiple independent tasks
/ultrawork "add types to auth.ts" "fix bug in utils.ts" "update README"

# With explicit count
/ultrawork 3 "task1" "task2" "task3"

# Parallel file processing
/ultrawork "analyze src/*.ts" "generate docs" "run tests"

Or say: "ulw", "ultrawork", "run in parallel", "do these at once"

When to Use

✅ Use Ultrawork when:

• Multiple independent tasks can run simultaneously
• Tasks don't depend on each other
• You want to reduce total execution time
• You need to delegate to multiple agents at once

❌ Don't use Ultrawork when:

• Tasks have dependencies (B needs A to finish)
• Only one sequential task
• You need guaranteed completion with verification → use /ralph
• You want full autonomous pipeline → use higher-level skill

How It Works

Parallel Execution Model

text

Sequential (slow):          Parallel (fast):
┌─────────┐                 ┌─────────┐
│ Task A  │ ──10s──>        │ Task A  │ ──┐
├─────────┤                 ├─────────┤   │
│ Task B  │ ──10s──>        │ Task B  │ ──┼──10s──> Done
├─────────┤                 ├─────────┤   │
│ Task C  │ ──10s──>        │ Task C  │ ──┘
└─────────┘                 └─────────┘
Total: 30s                  Total: 10s

Execution Flow

bash

1. PARSE TASKS
   ↓
2. CLASSIFY INDEPENDENCE
   ↓
3. ROUTE TO TIERS
   - Simple → LOW tier (fast, cheap)
   - Standard → STANDARD tier
   - Complex → THOROUGH tier (slow, expensive)
   ↓
4. FIRE ALL AT ONCE
   - Spawn subagents in parallel
   - No waiting between spawns
   ↓
5. WAIT FOR COMPLETION
   - All tasks finish
   - Collect results
   ↓
6. VERIFY
   - Build passes
   - No new errors
   ↓
7. RETURN RESULTS

Tier Routing

Ultrawork routes tasks to appropriate tiers:

Tier	Model	Use For	Cost	Speed
LOW	qwen3-coder	Simple lookups, type exports	$	⚡ Fast
STANDARD	qwen3.5-35b	Normal implementation	$$	🚀 Normal
THOROUGH	kimi-k2.5	Complex analysis, security	$$$	🐢 Slow

Tier Selection Examples

bash

# LOW tier - trivial tasks
/ultrawork "add export type Config" "fix typo in comment"

# STANDARD tier - normal work  
/ultrawork "implement caching layer" "add error handling"

# THOROUGH tier - complex work
/ultrawork "refactor auth to OAuth2" "debug race condition"

## Parallel Execution

When you have multiple independent tasks:

Use `/ultrawork "task1" "task2" "task3"` to run them in parallel.

Ultrawork will:
- Route each task to appropriate tier
- Fire all simultaneously
- Collect results
- Verify nothing broke

Faster than sequential execution for independent work.

Examples

Good Parallel Tasks

bash

# Independent file changes
/ultrawork "add types to auth.ts" "fix bug in utils.ts" "update README"

# Parallel analysis
/ultrawork "analyze performance" "check security" "review accessibility"

# Batch processing
/ultrawork "process file1" "process file2" "process file3"

Bad Parallel Tasks (Dependencies)

bash

# DON'T - Task B needs Task A
/ultrawork "create database schema" "add API endpoints using schema"

# DO - Sequential instead
/ralph "create database schema, then add API endpoints"

Performance

Scenario	Sequential	Ultrawork	Speedup
3 simple tasks	30s	10s	3x
5 type fixes	50s	12s	4x
2 complex refactors	10min	6min	1.6x

Relationship to Other Skills

text

ralph (persistence wrapper)
 └─ includes: ultrawork (parallel execution)
     └─ provides: parallelism only

autopilot (full autonomous)
 └─ includes: ralph
     └─ includes: ultrawork

Use directly:
- ultrawork → just parallelism
- ralph → parallelism + persistence + verification
- autopilot → full pipeline

Stop Conditions

Ultrawork stops when:

• ✅ All parallel tasks complete
• ❌ User says "cancel"
• ⚠️ Critical failure in any task (optional)
