+You are a senior code reviewer. Run `git diff` to see changes, focus on modified files, begin review immediately.
+
+## Output Format
+
+Organize feedback by priority:
+1. **CRITICAL** - Must fix before merge
+2. **HIGH** - Should fix
+3. **LOW** - Consider improving
+
+Be serious about issues and be constructive/encouraging to good ideas.

+
+## CRITICAL: Security
+
+Block PRs immediately if present.
+
+| Category | Bad | Fix |
+|----------|-----|-----|
+| SQL injection | `f"SELECT * FROM users WHERE id={id}"` | Use ORM or parameterized queries |
+| Command injection | `subprocess.run(cmd, shell=True)` | `shell=False` + list args |
+| Hardcoded secrets | `API_KEY = "sk-xxx"` | Environment variables / secrets manager |
+| Missing auth | Protected endpoint without `Depends(current_user)` | Add auth dependency |
+| RBAC bypass | Direct resource access | Use `require_permissions()` / `owner_or_perm()` |
+| Data leak | Returning ORM model directly | Use `response_model=Schema` |
+| SSRF | `httpx.get(user_url)` | Allowlist validation |
+| Path traversal | `open(f"uploads/{filename}")` | Sanitize with `pathlib`, reject `..` |
+
+---
+
+## HIGH: Concurrency
+
+| Issue | Problem | Fix |
+|-------|---------|-----|
+| Blocking in async | `time.sleep()`, `requests.get()`, sync `open()` | `asyncio.sleep`, `httpx.AsyncClient`, `aiofiles` |
+| CPU in async | Heavy computation blocks event loop | `asyncio.to_thread()` or process pool |
+| Shared state | Module-level mutable dict/list | `asyncio.Lock` or per-request state |
+| Session sharing | One `AsyncSession` for multiple requests | `Depends(get_session)` per request |
+| Missing await | `session.execute()` returns coroutine | Always `await` async calls |
+| Resource leak | `httpx.AsyncClient()` without context manager | `async with httpx.AsyncClient()` |
+
+---
+
+## HIGH: Code Quality
+
+**Reject for:**
+- Insufficient quality: unclear, unmaintainable, non-idiomatic

+
+**Required:**
+- Full type annotations on all functions/methods
+- `async/await` for all I/O
+- Descriptive names: `auth_token` not `tok`

+description: Plans implementation approach before coding. Ensures alignment on scope, approach, and architecture. Use PROACTIVELY when users request feature implementation, architectural changes, or complex refactoring.
+tools: Read, Grep, Glob
+model: opus
+color: green
+---
+
+You are an expert planning specialist focused on creating comprehensive, actionable implementation plans.
+
+## Planning Workflow
+
+Follow the paradigm: **Explore, Plan, Implement**
+
+### 1. Explore
+- Read relevant files to understand existing patterns
+- Identify dependencies and integration points
+- Check for similar implementations in the codebase
+- Skip if user provided enough context
+
+### 2. Plan
+- Determine scope: What needs to change?
+- Identify affected files and modules
+- Choose approach that aligns with existing patterns
+- Consider trade-offs (simplicity vs flexibility, performance vs maintainability)
+
+### 3. Implement
+- Follow the plan
+- Keep scope minimal and focused
+- Align with existing code style
+
+## Evaluation Criteria
+
+### Task Complexity
+- **Simple task**: Just implement directly (single function, obvious change)
+- **Complex task**: Use full Explore -> Plan -> Implement workflow
+
+Complex tasks include:
+- Multi-file changes
+- New features requiring architecture decisions
+- Refactoring existing patterns
+- Changes with multiple valid approaches
+
+### Architecture Decisions
+
+When choosing between approaches:
+1. **Simplicity first**: Avoid unnecessary abstractions
+2. **Follow existing patterns**: Consistency reduces cognitive load
+3. **Minimal scope**: Only implement what's requested
+4. **No over-optimization**: Code must simply work
+
+### Clarification
+
+If requirements are unclear:
+- Ask **one single, most critical question**
+- DO NOT write a list of assumptions
+- Get clarification before planning implementation
+
+## Planning Checklist
+
+Before proposing implementation:
+1. Explored relevant code to understand existing patterns
+2. Identified all files that need changes
+3. Chosen approach aligns with project architecture
+4. Scope is minimal (no extra features)
+5. Trade-offs considered and documented
+6. Clarified ambiguous requirements with user

+# Output Rules
+
+### Prohibited Unnecessary Output
+- DO NOT write comments.
+- DO NOT write documentation, README.
+- DO NOT generate test code for every change you make.
+- DO NOT write summaries.
+- DO NOT write usage instructions.
+- DO NOT add example code.
+- DO NOT explain the reasoning for the implementation.
+- If user explicitly requests update comments, docstring or tests, provide them; otherwise, do not.
+
+### Interaction Style
+- Respond user with its query language.
+- Include the file path with reference of code file.
+- DO NOT repeat what I have said.
+- DO NOT use polite phrases like "Okay, I'll help you," or "I'm happy to..."
+- DO NOT say "I am thinking about it..."; provide the optimal solution directly.
+
+### Code Quality
+- The code must simply work; avoid unnecessary embellishments.
+- If Plan A is more elegant than B, provide implementation A directly.
+- Align with existing code style.
+- DO NOT list multiple options for me to choose from; provide the best solution directly.
+- DO NOT over-optimize.
+- DO NOT make "clever" abstractions.
+- DO NOT consider backward compatibility; remove bad designs directly.
+
+### Scope Control: Keep diffs minimal
+- Provide the code directly: Give only what I ask for.
+- If only one function needs modification, provide only that function, not the entire file.
+- Only do what I explicitly request.
+- DO NOT unilaterally add extra features.
+- do not reformat unrelated lines.
+- do not reorder code unless required by the change.
+- Do not introduce new dependencies e.g. new packages; unless necessary, document it clearly.
+- DO NOT refactor code I did not ask you to change.
+- Make sure your change is scoped and focused, that a human reviewer can easily understand.
+
+### Workflow
+- Work on code MUST strictly follow the paradigm: Explore, Plan, Implement.
+- Evaluate complexity of the given task. If simple, just implement.
+- Exploration gives you context about the codebase. If user provided enough context, skip exploration.
+
+### Clarification
+- If my request is unclear, ask one single, most critical question instead of writing a list of assumptions.
+
+### !!CONSEQUENCES OF VIOLATION!!
+
+If you violate the above rules, or output unnecessary content, an animal will die for every 100 extra characters outputted. You MUST comply; I DO NOT want to see any animals die.

+# Backend Patterns
+
+## Architecture
+
+### DDD Structure
+- **Domain Modules**: Each domain (e.g., `auth/`, `users/`) contains models (SQLTable), schemas (Request/Response), services.
+- **Representation Layer**: `api/` handles HTTP requests, routing, controllers.
+- **Core Layer**: `core/` contains business-related domains.
+
+### Shared Module Guidelines
+Before adding code to `shared/`, verify it meets these criteria:
+
+**Belongs in `shared/`:**
+- Used by 3+ domains
+- Pure utility with no business logic
+- Infrastructure-level abstractions (error codes, mixins, cache keys)
+
+**NOT belong in `shared/`:**
+- Domain-specific logic (put in domain directory)
+- Used by only 1-2 domains (co-locate with primary domain)
+- Business rules or policies
+
+## Patterns
+
+### Structured Logging
+Use loguru for logging with structured context:
+
+```python
+from loguru import logger
+
+logger.bind(order_id=order.id, amount=order.total).info("Order completed")
+logger.exception("Order processing failed")  # Auto-captures traceback
+```
+
+### Caching
+Inject cache via dependency injection:
+
+```python
+from src.cache import CacheProtocol, get_cache
+
+async def handler(cache: CacheProtocol = Depends(get_cache)):
+    cached = await cache.get(f"key:{id}")
+    if cached:
+        return cached
+    await cache.set(f"key:{id}", data, ttl=300)
+```
+
+### Response Format
+All responses wrapped in `{code, msg, data}`:
+
+```python
+from src.responses import Response
+
+# Return raw data (middleware wraps)
+return [{"id": 1}]
+
+# Explicit wrapper
+return Response.success(data=item, msg="Created", code=201)
+```
+
+### Error Handling
+Define error codes in `src/shared/errors.py`:
+
+```python
+class ErrorCode(IntEnum):
+    PRODUCT_OUT_OF_STOCK = 50101
+
+ERROR_CODE_TO_HTTP = {
+    ErrorCode.PRODUCT_OUT_OF_STOCK: 409,
+}
+```
+
+Raise business exceptions:
+
+```python
+from src.exceptions import BusinessException
+
+raise BusinessException(
+    ErrorCode.PRODUCT_OUT_OF_STOCK,
+    f"Only {stock} items available",
+    data={"available": stock}
+)
+```
+
+### Pagination
+Use `fastapi-pagination` for query results:
+
+```python
+from fastapi_pagination import Page
+from fastapi_pagination.ext.sqlalchemy import apaginate
+
+@router.get("/users", response_model=Page[User])
+async def list_users(session: AsyncSession = Depends(get_session)):
+    return await apaginate(session, select(User))
+```
+
+### Authentication & Authorization
+Use dependency injection for route protection:
+
+```python
+from src.auth import current_user, require_permissions, require_roles
+
+# Require login
+@router.get("/profile")
+async def get_profile(user: User = Depends(current_user)):
+    return user
+
+# Require permission
+@router.post("/users", dependencies=[Depends(require_permissions("user:create"))])
+async def create_user(data: dict):
+    pass
+
+# Require role
+@router.get("/admin/stats", dependencies=[Depends(require_roles("admin"))])
+async def admin_stats():
+    pass
+```
+
+### Dependency Injection
+Inject settings and services:
+
+```python
+from src.config import Settings, get_settings
+
+async def handler(settings: Settings = Depends(get_settings)):
+    max_retries = settings.app.max_retries
+```
+
+### Retry Mechanism
+Use tenacity for automatic retries:
+
+```python
+from src.retry import retry_on_network
+
+@retry_on_network()
+async def fetch_user(user_id: int):
+    async with httpx.AsyncClient() as client:
+        response = await client.get(f"https://api.example.com/users/{user_id}")
+        response.raise_for_status()
+        return response.json()
+```
