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:

TierModelUse ForCostSpeedLOWqwen3-coderSimple lookups, type exports$⚡ FastSTANDARDqwen3.5-35bNormal implementation$$🚀 NormalTHOROUGHkimi-k2.5Complex analysis, security$$$🐢 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"

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)
