# 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

```
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"
```

## Implementation

```bash
#!/bin/bash
# <workspace>/skills/ultrawork/ultrawork.sh

# Parse tasks from arguments
TASKS=("$@")
NUM_TASKS=${#TASKS[@]}

echo "=== ULTRAWORK: Parallel Execution ==="
echo "Tasks: $NUM_TASKS"
echo ""

# Create temp directory for results
RESULTS_DIR=$(mktemp -d)
trap "rm -rf $RESULTS_DIR" EXIT

# Function to execute task in background
execute_task() {
  local task_id=$1
  local task_desc=$2
  local output_file="$RESULTS_DIR/task-$task_id.json"
  
  # Determine tier based on task complexity
  local tier="STANDARD"
  local model="lmstudio/qwen3.5-35b-a3b-uncensored-hauhaucs-aggressive"
  
  if [[ "$task_desc" =~ (simple|lookup|typo|export|add type) ]]; then
    tier="LOW"
    model="lmstudio/qwen3-coder-30b-a3b-instruct-mlx"
  elif [[ "$task_desc" =~ (complex|refactor|security|architect|debug.*race) ]]; then
    tier="THOROUGH"
    model="moonshot/kimi-k2.5"
  fi
  
  echo "  [Task $task_id] Tier: $tier | Model: $model"
  
  # Spawn subagent for task
  openclaw sessions spawn \
    --task "$task_desc" \
    --model "$model" \
    --runtime subagent \
    --mode run \
    --output "$output_file" \
    2>/dev/null &
  
  # Save PID
  echo $! > "$RESULTS_DIR/task-$task_id.pid"
}

# Fire all tasks simultaneously
echo "Launching tasks..."
for i in "${!TASKS[@]}"; do
  task_id=$((i + 1))
  execute_task "$task_id" "${TASKS[$i]}"
done

echo ""
echo "Waiting for completion..."

# Wait for all background jobs
for pid_file in "$RESULTS_DIR"/*.pid; do
  if [[ -f "$pid_file" ]]; then
    pid=$(cat "$pid_file")
    wait $pid 2>/dev/null || true
  fi
done

echo ""
echo "=== Results ==="

# Collect and display results
SUCCESS_COUNT=0
FAIL_COUNT=0

for result_file in "$RESULTS_DIR"/task-*.json; do
  if [[ -f "$result_file" ]]; then
    task_id=$(basename "$result_file" | sed 's/task-//' | sed 's/.json//')
    
    # Check if result exists and parse
    if [[ -s "$result_file" ]]; then
      echo "  [Task $task_id] ✅ Complete"
      SUCCESS_COUNT=$((SUCCESS_COUNT + 1))
    else
      echo "  [Task $task_id] ❌ Failed"
      FAIL_COUNT=$((FAIL_COUNT + 1))
    fi
  fi
done

echo ""
echo "Summary: $SUCCESS_COUNT succeeded, $FAIL_COUNT failed"

# Lightweight verification
echo ""
echo "Verifying..."

# Check build if applicable
if [[ -f "package.json" ]]; then
  if npm run build > /dev/null 2>&1; then
    echo "✅ Build passes"
  else
    echo "⚠️  Build has errors"
  fi
fi

# Check for new errors
if [[ -f "package.json" ]]; then
  if npm test > /dev/null 2>&1; then
    echo "✅ Tests pass"
  else
    echo "⚠️  Tests have failures"
  fi
fi

echo ""
echo "=== ULTRAWORK: Complete ==="
```

## Integration with OpenClaw

Add to `AGENTS.md`:

```markdown
## 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

```
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)

## Output Format

```
=== ULTRAWORK: Parallel Execution ===
Tasks: 3

Launching tasks...
  [Task 1] Tier: LOW | Model: qwen3-coder
  [Task 2] Tier: STANDARD | Model: qwen3.5-35b
  [Task 3] Tier: LOW | Model: qwen3-coder

Waiting for completion...

=== Results ===
  [Task 1] ✅ Complete
  [Task 2] ✅ Complete
  [Task 3] ✅ Complete

Summary: 3 succeeded, 0 failed

Verifying...
✅ Build passes
✅ Tests pass

=== ULTRAWORK: Complete ===
```

## Dependencies

- `openclaw` CLI with subagent support
- Background job support (`&`, `wait`)
- Standard POSIX tools

## Version History

- 1.0.0: Initial implementation based on oh-my-codex ultrawork skill
