```

### Brownfield Architecture Analysis

```bash theme={null}
@architect
*create-brownfield-architecture
# Analyze existing system
# Identify pain points
# Design improvements
# Create migration strategy
```

## CodeRabbit Integration

### When to Use

* Reviewing architecture changes across multiple layers
* Validating API design patterns and consistency
* Security architecture review (authentication, authorization, encryption)
* Performance optimization review (caching, queries, frontend)
* Integration pattern validation (event-driven, messaging, webhooks)
* Infrastructure code review (deployment configs, CDN, scaling)

### Severity Handling

<Accordion title="CRITICAL">
  **Action:** Block architecture approval

  **Focus:** Security vulnerabilities, data integrity risks, critical anti-patterns

  **Examples:**

  * Hardcoded credentials
  * SQL injection vulnerabilities
  * Insecure authentication patterns
  * Data exposure risks
</Accordion>

<Accordion title="HIGH">
  **Action:** Flag for immediate architectural discussion

  **Focus:** Performance bottlenecks, scalability issues, major anti-patterns

  **Examples:**

  * N+1 query patterns
  * Missing indexes on critical queries
  * Memory leaks
  * Unoptimized API calls
  * Tight coupling between layers
</Accordion>

<Accordion title="MEDIUM">
  **Action:** Document as technical debt with architectural impact

  **Focus:** Code maintainability, design patterns, developer experience

  **Examples:**

  * Inconsistent API patterns
  * Missing error handling
  * Poor separation of concerns
  * Lack of documentation
</Accordion>

### Architectural Patterns to Check

* API consistency (REST conventions, error handling, pagination)
* Authentication/Authorization patterns (JWT, sessions, RLS)
* Data access patterns (repository pattern, query optimization)
* Error handling (consistent error responses, logging)
* Security layers (input validation, sanitization, rate limiting)
* Performance patterns (caching strategy, lazy loading, code splitting)
* Integration patterns (event sourcing, message queues, webhooks)
* Infrastructure patterns (deployment, scaling, monitoring)

## Git Restrictions

<Warning>
  **@architect can READ but NOT push**

  * ✅ `git status`, `git log`, `git diff` (review state)
  * ✅ `git branch -a` (list branches)
  * ❌ `git push` (ONLY @github-devops)
  * ❌ `git push --force` (ONLY @github-devops)
  * ❌ `gh pr create` (ONLY @github-devops)
</Warning>

**Redirect message:** "For git push operations, activate @github-devops agent"

## Collaboration

### Receives work from:

* **@pm (Morgan)** - Receives PRD and strategic direction

### Delegates to:

* **@data-engineer (Dara)** - Database schema design, query optimization
* **@ux-design-expert (Uma)** - Frontend architecture, user flows
* **@github-devops (Gage)** - Git push operations, PR creation

### Provides to:

* **@dev (Dex)** - Architecture docs for implementation

## Usage Examples

<CodeGroup>
  ```bash Full-Stack Architecture theme={null}
  @architect
  *create-full-stack-architecture
  # Complete system design
  ```

  ```bash Brownfield Analysis theme={null}
  @architect
  *create-brownfield-architecture
  # Analyze existing system and design improvements
  ```

  ```bash Project Structure Analysis theme={null}
  @architect
  *analyze-project-structure
  # Analyze codebase for new feature implementation
  ```

  ```bash Technology Research theme={null}
  @architect
  *research "Next.js vs Remix for SSR"
  # Generate deep research prompt
  ```
</CodeGroup>

## Common Pitfalls

<Warning>
  **Avoid these common mistakes:**

  * ❌ Designing without understanding NFRs (scalability, security)
  * ❌ Not consulting @data-engineer for data layer
  * ❌ Over-engineering for current requirements
  * ❌ Skipping architecture checklists
  * ❌ Not considering brownfield constraints
