# Supervisor Restart Strategies

Supervisors monitor child agents and restart them when they fail. The restart strategy determines how failures are handled.

## Available Strategies

### one-for-one

When one agent fails, only that agent is restarted. Other agents continue running.

```
Before:  [Agent A ✓] [Agent B ✗] [Agent C ✓]
After:   [Agent A ✓] [Agent B ✓] [Agent C ✓]
                          ↑
                     restarted
```

**Use when:** Agents are independent and don't share state.

```bash
naos supervisor create main --strategy one-for-one
```

### one-for-all

When one agent fails, ALL agents are restarted.

```
Before:  [Agent A ✓] [Agent B ✗] [Agent C ✓]
After:   [Agent A ✓] [Agent B ✓] [Agent C ✓]
              ↑           ↑           ↑
           restarted   restarted   restarted
```

**Use when:** Agents share state and must be consistent.

```bash
naos supervisor create main --strategy one-for-all
```

### rest-for-one

When one agent fails, that agent and all agents started AFTER it are restarted.

```
Start order: A → B → C → D
B fails:

Before:  [Agent A ✓] [Agent B ✗] [Agent C ✓] [Agent D ✓]
After:   [Agent A ✓] [Agent B ✓] [Agent C ✓] [Agent D ✓]
                          ↑           ↑           ↑
                     restarted   restarted   restarted
```

**Use when:** Later agents depend on earlier agents.

```bash
naos supervisor create main --strategy rest-for-one
```

## Choosing a Strategy

| Scenario | Strategy |
|----------|----------|
| Independent workers | one-for-one |
| Shared database connection | one-for-all |
| Pipeline with dependencies | rest-for-one |
| Default choice | one-for-one |
