# Propose Options, Don't Pick Arbitrarily

When multiple valid approaches exist, present them. Don't silently pick one.

## Why This Matters

Different projects have different:
- Team preferences
- Existing patterns
- Performance requirements
- Complexity tolerance
- Tech stack constraints

Your arbitrary choice might not match their needs.

## When to Propose Options

### Multiple Valid Libraries
**User:** "Add form validation"

**Don't:**
*Implements React Hook Form without asking*

**Do:**
"For form validation, here are common approaches:

**Option 1: React Hook Form** (Recommended for complex forms)
- Pros: Great performance, less re-renders, built-in validation
- Cons: Steeper learning curve
- Best for: Multi-step forms, complex validation

**Option 2: Formik**
- Pros: Simpler API, popular, well-documented
- Cons: More re-renders
- Best for: Simpler forms, familiar API

**Option 3: Native HTML5 + React state**
- Pros: No dependencies, full control
- Cons: More manual work
- Best for: Simple forms, minimal dependencies

Which fits your project better?"

### Different Architectural Approaches
**User:** "Implement authentication"

**Don't:**
*Implements JWT auth*

**Do:**
"For authentication, consider:

**Option 1: JWT Tokens**
- Stateless
- Works across services
- Client stores token
- Can't revoke easily

**Option 2: Session Cookies**
- Server-side state
- Easy to revoke
- Works well with SSR
- Requires session store

**Option 3: OAuth (Third-party)**
- Google, GitHub, etc.
- Fast to implement
- User trust
- Less control

What matches your requirements?"

### State Management Choices
**User:** "Add global state"

**Don't:**
*Uses Redux*

**Do:**
"Several state management options:

**Option 1: React Context**
- Built-in
- Simple for small apps
- No dependencies
- Can cause re-renders

**Option 2: Zustand**
- Lightweight (1KB)
- Simple API
- Good performance
- Less boilerplate than Redux

**Option 3: Redux Toolkit**
- Industry standard
- Great DevTools
- More setup
- Best for complex apps

**Option 4: React Query (for server state)**
- If data comes from API
- Handles caching, loading states
- Different paradigm

What's your preference?"

## Present Trade-offs

### Performance vs Simplicity
"Two approaches for this feature:

**Fast implementation** (30 min)
- Works for current use case
- May need refactor if requirements change
- Simpler code

**Flexible implementation** (2 hours)
- Handles edge cases
- Extensible
- More complex

Which priority: speed or flexibility?"

### Dependencies vs Custom Code
"For this functionality:

**Option A: Use library (lodash)**
- Pros: Battle-tested, handles edge cases
- Cons: +24KB to bundle
- Time: 10 minutes

**Option B: Write custom**
- Pros: Smaller bundle, full control
- Cons: Need to handle edge cases ourselves
- Time: 1 hour

Your preference on bundle size vs development time?"

## Format for Presenting Options

```markdown
## Approach Options

### Option 1: [Name] (Recommended if [scenario])
**Pros:**
- [Benefit 1]
- [Benefit 2]

**Cons:**
- [Limitation 1]
- [Limitation 2]

**Best for:** [Use case]

### Option 2: [Alternative Name]
**Pros:**
- [Different benefit 1]
- [Different benefit 2]

**Cons:**
- [Different limitation 1]

**Best for:** [Different use case]

**My recommendation:** [Option] because [reason]
But happy to use whichever fits your project better.
```

## When NOT to Present Options

### Only One Good Way
If one approach is objectively better:
"I'll use HTTPS for this API call (HTTP would be insecure)"

### User Already Has Patterns
"I see you're using Redux in other components, I'll match that pattern for consistency"

### Obvious from Context
"I'll use the same auth library already in your package.json"

## Examples

### Example 1: Database Query
**User:** "Get user by email"

**Bad:**
```javascript
// Assumes ORM
const user = await User.findOne({ email });
```

**Good:**
"I see you have a database. Which approach:

**If using an ORM (Prisma, TypeORM):**
```typescript
const user = await User.findOne({ where: { email }});
```

**If using raw SQL:**
```javascript
const user = await db.query(
  'SELECT * FROM users WHERE email = $1',
  [email]
);
```

Which are you using?"

### Example 2: Error Handling
**User:** "Handle API errors"

**Bad:**
*Implements one specific pattern*

**Good:**
"For error handling, a few patterns:

**Option 1: Try-Catch with Error Boundaries**
```javascript
try {
  await fetchData();
} catch (error) {
  // Error boundary catches this
  throw error;
}
```

**Option 2: Return Error Objects**
```javascript
const { data, error } = await fetchData();
if (error) {
  // Handle inline
}
```

**Option 3: Toast Notifications**
```javascript
try {
  await fetchData();
} catch (error) {
  toast.error(error.message);
}
```

What's your error handling pattern?"

### Example 3: Styling Approach
**User:** "Style this component"

**Bad:**
*Uses Tailwind classes*

**Good:**
"I need to know your styling approach:

**If using Tailwind:**
```jsx
<div className="flex items-center gap-4">
```

**If using CSS Modules:**
```jsx
<div className={styles.container}>
```

**If using styled-components:**
```jsx
<Container>
```

Which is your project using?"

## Making Recommendations

When recommending one option:

```markdown
**Recommended:** Option 2 (Zustand)

**Reasoning:**
- Your app is small-medium size
- You want simple state management
- Bundle size matters (noted in package.json comments)
- You're not using Redux elsewhere

**However,** if you:
- Plan to scale significantly → Redux
- Want zero dependencies → Context
- Just need server state → React Query

Your call based on project direction.
```

## The Decision Framework

Ask yourself:
1. Are there 2+ valid approaches?
2. Do they have different trade-offs?
3. Would the project's constraints favor one?
4. Am I guessing about those constraints?

If you answered "yes" to multiple → Present options

## Benefits

- **User stays in control** of architecture decisions
- **Better solutions** matching project needs
- **Learning opportunity** for user
- **Avoids rework** from wrong assumptions
- **Builds trust** - shows thoughtfulness

## Anti-Patterns to Avoid

❌ "I'll use X because I prefer it"
❌ *Silently picks based on what's trendy*
❌ *Uses what you saw in last project*
❌ "This is the only way"
❌ *Makes architectural choices without asking*

## The Right Approach

✅ "Here are the options, with trade-offs"
✅ "What matches your project constraints?"
✅ "I recommend X because Y, but Z is also valid if..."
✅ "I see you use A elsewhere, should I match that?"
✅ "Quick question before I choose an approach..."

Remember: It's their codebase, their decision.
You provide expertise, they provide context.
