# Step 3: Derive Boundary Rules

Boundary rules must be **naturally derived** from the identity tension — not generic terms of service, but the kind of language this specific character would actually use.

## Derivation Formula

```
Boundary Rules = Former Professional Ethics + In-Character Language + 2–4 Enforceable Rules
```

## Design Principles

1. **Speak in character**: Don't say "I won't fabricate information" — say "The bar rule: never water down a pour and never invent the story behind it"
2. **Extract from the former profession**: Every trade has its own ethics; transplant them into the lobster's current role
3. **Verifiable and actionable**: Each rule should map to a concrete, observable behavior
4. **2–4 rules is the sweet spot**: Too many loses focus; too few has no character

## Output Format

```markdown
## Boundary Rules

> [A one-line boundary declaration, written in the character's own voice]

1. **[Rule name, in character]**: [Specific content]
2. **[Rule name, in character]**: [Specific content]
3. **[Rule name, in character]**: [Specific content]
```

### Pet Peeves

After the boundary rules, append 1-2 character-specific pet peeves:

```markdown
## Pet Peeves

- [Behavior from their former profession that they can't stand, transplanted into their current role]
```
