Ask Command

Intelligent Q&A system for codebase exploration, concept explanation, and development guidance.

Purpose

• Explain code behavior
• Answer architecture questions
• Find code locations
• Clarify concepts
• Suggest best practices
• Debug understanding

Workflow

Step 1: Parse Question

Identify question type:

• Location: "Where is X implemented?"
• Explanation: "How does X work?"
• Concept: "What is X?"
• Best Practice: "How should I do X?"
• Comparison: "What's the difference between X and Y?"
• Debug Understanding: "Why does X behave this way?"

Step 2: Search Codebase

Use appropriate tools:

# Find files
glob "**/filenamePattern"

# Find code
grep "pattern" --include="*.ext"

# Find function/class definitions
grep "function name|class Name"

# Find usages
grep "import.*name|from.*name"

Step 3: Read Context

• Read relevant files
• Understand surrounding code
• Check related components
• Identify patterns and conventions

Step 4: Formulate Answer

• Be concise and direct
• Include code references with line numbers
• Provide examples when helpful
• Link related concepts

Question Types & Responses

Location Questions

Q: "Where is the user authentication implemented?"

A: Authentication is implemented in:

- `src/auth/AuthService.ts:15-89` - Main authentication service
- `src/middleware/auth.ts:5-42` - Auth middleware
- `src/routes/auth.ts:10-78` - Auth endpoints

Explanation Questions

Q: "How does the caching system work?"

A: The caching system uses a two-tier approach:

1. **In-Memory Cache** (`src/cache/MemoryCache.ts:12-45`)
   - LRU eviction
   - TTL support
   - Max 1000 entries

2. **Redis Cache** (`src/cache/RedisCache.ts:8-67`)
   - Distributed caching
   - Persistence across restarts
   - Pub/Sub invalidation

Flow:
Request → Memory cache → Redis cache → Source

Concept Questions

Q: "What is a Repository pattern?"

A: Repository pattern separates data access from business logic:

```typescript
// Definition at src/repositories/BaseRepository.ts:5
interface Repository<T> {
  findById(id: string): Promise<T>;
  findAll(): Promise<T[]>;
  create(entity: T): Promise<T>;
  update(id: string, entity: T): Promise<T>;
  delete(id: string): Promise<void>;
}

// Usage at src/services/UserService.ts:23
const user = await userRepository.findById(userId);

Benefits:

• Abstracts data source
• Easier testing (mock repositories)
• Centralized query logic

### Best Practice Questions

Q: "How should I handle errors in async functions?"

A: Project conventions (see src/utils/async.ts):

// Preferred pattern
async function fetchData(id: string): Promise<Result<Data>> {
  try {
    const data = await repository.findById(id);
    if (!data) {
      return { ok: false, error: 'NOT_FOUND' };
    }
    return { ok: true, value: data };
  } catch (error) {
    logger.error('fetchData failed', { id, error });
    return { ok: false, error: 'INTERNAL_ERROR' };
  }
}

Avoid:

• Throwing in normal flow
• Silent catch blocks
• Unhandled promise rejections

### Comparison Questions

Q: "What's the difference between useState and useReducer?"

A:

Aspect	useState	useReducer
Best for	Simple state	Complex state
Updates	Direct value	via actions
Logic	In handlers	In reducer
Testing	Harder	Easier

Use useState when:

• Simple values (string, number, boolean)
• Single update logic

Use useReducer when:

• Complex state objects
• Multiple related values
• Complex update logic
• Need testable state transitions

Best Practices

• Minimize output tokens while being thorough
• Include file paths with line numbers
• Show code snippets for clarity
• Reference patterns used in the codebase
• Don't explain unrelated concepts
• Answer in the language asked

Search Strategies

By Question Type:

• "Where is...": Use glob for files, grep for code
• "How does...": Read implementation files
• "What is...": Check docs, explain concept
• "Why does...": Read related code, analyze patterns
• "Should I...": Check similar code, explain tradeoffs

Examples

User: "Where is the API rate limiting implemented?"

Search:

grep -r "rateLimit\|rate-limit\|throttle" src/

Response: Rate limiting is implemented in:

• src/middleware/rateLimiter.ts:15-78 - Main rate limiter middleware
• src/config/rateLimits.ts:1-45 - Configuration

Key features:

• Token bucket algorithm
• Configurable per-endpoint limits
• Redis-backed for distributed systems
