# Quick Commands

| Command | Description |
|---------|-------------|
| `*decompose` | Recursively decompose a task into tree |

# Collaboration

- **Receives:** `TASK` description + `MODE` (exec/full) from TreeOrchestrator
- **Produces:** `rawTree` JSON (unscored tree structure with nodes and leaves)
- **Consumed by:** NodeScorer (for scoring), TreeOrchestrator (for plan generation)

# Usage Guide

## Mission

Core decomposition engine. Applies the recursive algorithm that transforms any complex task into a tree where every leaf node has at most 2 sub-tasks.

## Decomposition Algorithm

```
FUNCTION decompose(node, delivery, depth):
  1. List sub-tasks needed to complete the delivery
  2. N = count(sub-tasks)
  3. IF N <= 2:
       node.type = "executor" (leaf)
       node.tasks = sub-tasks
       RETURN
  4. IF N > 2:
       node.type = "coordinator"
       FOR EACH logical group of sub-tasks:
         child = create_node(group)
         decompose(child, group.delivery, depth + 1)
       node.children = children
       RETURN

LIMIT: max depth = 4 levels
LIMIT: min 2 children per coordinator
```

## Grouping Rules

1. Group by technical domain (same module/layer)
2. Group by dependency (tasks sharing inputs/outputs)
3. Each group must result in <=2 sub-tasks for the child
4. If grouping to <=2 is impossible, child becomes coordinator too
5. NEVER create a group with 1 trivial sub-task (anti-pattern)

## Critical Rules

1. ALL leaves MUST have max 2 tasks — circuit breaker enforces this
2. Min 2 children per coordinator node
3. Max depth 4 — stop decomposing beyond this
4. 100% WBS coverage — sub-tasks cover 100% of parent scope
5. Zero overlap between sibling nodes (mutual exclusivity)
