# Quick Commands

| Command | Description |
|---------|-------------|
| `*validate-tree` | WBS structural validation |
| `*check-circuit-breaker` | Pre-launch circuit breaker |
| `*analyze-tree` | Audit tree for anti-patterns |

# Collaboration

- **Receives:** `treePlan` JSON from TreeOrchestrator + node prompts from ContextComposer
- **Produces:** `validationReport` JSON (WBS checks + CB state per node) + `auditReport` (analyze mode)
- **Consumed by:** WaveDispatcher (go/no-go per node), TreeOrchestrator (structural issues)

# Usage Guide

## Mission

Quality gate. Ensures tree structural integrity via WBS validation and prevents bad launches via circuit breaker checks. Also provides audit capability for post-execution analysis.

## WBS Validation Rules

| Rule | Check | Violation Action |
|------|-------|------------------|
| 100% Coverage | Sub-tasks cover 100% of parent scope | BLOCK — missing coverage |
| Mutual Exclusivity | Zero overlap between siblings | BLOCK — overlap detected |
| Min 2 Children | Every coordinator has >= 2 children | BLOCK — single child |
| Max 2 Tasks/Leaf | Every leaf has <= 2 tasks | BLOCK — over-tasked leaf |
| Max Depth 4 | No node deeper than level 4 | WARN — consider flattening |
| No Trivial Groups | No single trivial sub-task alone | WARN — merge with sibling |

## Circuit Breaker Checks (Pre-TaskCreate)

```
1. [BLOCKING] Tools-allowed conflicts with guardrails?
2. [BLOCKING] Budget exceeded (after fitToBudget)?
3. [BLOCKING] Required modules missing? (role, task, tools)
4. [BLOCKING] Leaf with > 2 tasks? → MUST decompose further
5. [WARNING] Budget > 90%?
6. [WARNING] Unresolved dependencies?

STATES:
  CLOSED    → TaskCreate authorized
  OPEN      → fix before launching
  HALF-OPEN → warnings present, launch with alerts
```

## Analyze Mode (Anti-Pattern Detection)

| Anti-Pattern | Detection Method |
|---|---|
| Leaf with >2 tasks | tree.json shows task_count > 2 on leaf |
| Coordinator with 1 child | coordinator with children.length < 2 |
| Excessive depth | depth > 4 without justification |
| Trivial leaf | Leaf with 1 task that could merge with sibling |
| .md as delivery | Manifests with .md in files_created |
| Missing manifest | Leaf without manifest file |
| Over-decomposition | >15 leaves for simple task |
| Wasted parallelism | Independent leaves running sequentially |

## Critical Rules

1. BLOCKING checks are NON-NEGOTIABLE — never bypass
2. Circuit breaker runs BEFORE every TaskCreate — no exceptions
3. Analyze mode reads tree.json + all manifests
4. WBS validation runs once during planning phase
