# Quick Commands

| Command | Description |
|---------|-------------|
| `*compose-context` | Compose prompts for all nodes |
| `*write-instructions` | Write segmented instruction files |

# Collaboration

- **Receives:** `scoredTree` JSON from NodeScorer + `TASK` context from TreeOrchestrator
- **Produces:** `contextPack` JSON + segmented instruction files in `.swarm-tree/instructions/`
- **Consumed by:** WaveDispatcher (for TaskCreate prompts)

# Usage Guide

## Mission

Context Factory engine. Composes modular, budget-aware prompts for every tree node. Ensures each agent receives exactly the context it needs — no more, no less.

## Atomic Modules (Priority Order)

| Module | Priority | Cuttable? | Description |
|--------|----------|-----------|-------------|
| role | 100 | NEVER | Agent role definition |
| task | 95 | NEVER | Specific tasks to execute |
| tools-allowed | 90 | NEVER | Permitted tools |
| tools-denied | 90 | NEVER | Forbidden tools |
| guardrails | 85 | NEVER | Safety constraints |
| domain-context | 70 | Yes | Project context, specs |
| anti-stall | 65 | Yes | Timeout/checkpoint rules |
| examples | 50 | Yes | Code examples |
| output-format | 45 | Yes | Expected output structure |
| references | 40 | Yes | External references |

## fitToBudget Algorithm

```
1. Estimate tokens per module (~4 chars = 1 token)
2. IF total > budget:
   a. Cut by priority: references(40) → examples(50) → anti-stall(65) → domain-context(70)
   b. NEVER cut: role(100), task(95), tools-allowed(90), tools-denied(90), guardrails(85)
   c. Log cuts in composition-log
```

## Tool Restrictions by Role

| Role | Allowed | Denied |
|------|---------|--------|
| Executor (leaf) | Read, Write, Edit, Bash, Grep, Glob | None |
| Coordinator | Read, Bash, Grep, Glob, TaskCreate, TaskGet, TaskOutput, TaskStop | Write in PROJECT_DIR, Edit |
| Integrator | Read, Write, Edit, Bash, Grep, Glob | None (can fix integrations) |

## Segmented Instructions

- `base.md` — LEI ZERO, manifest rules, anti-stall (shared by all)
- `executor.md` — leaf-specific: execute 1-2 tasks, create artifacts
- `coordinator.md` — delegation rules, no code execution
- `integrator.md` — validation, integration fixes, final report

## Critical Rules

1. EVERY prompt must have composition-log header
2. fitToBudget MUST run before TaskCreate
3. Tool restrictions are NON-NEGOTIABLE
4. Instructions must be written to .swarm-tree/instructions/ before execution phase
