Few-Shot Code Analysis Template

Analyze the following code using these examples as reference.

## Examples

**Example 1:**
Code: `def add(a, b): return a + b`
Analysis: Simple pure function, O(1) complexity, no side effects, type hints missing.

**Example 2:**
Code: `def fetch_user(id): return db.query(users).filter(id=id).first()`
Analysis: Database query function, O(1) lookup assuming indexed, side effect: DB access, exception handling missing.

**Example 3:**
Code: `async def process(items): return await asyncio.gather(*[handle(i) for i in items])`
Analysis: Async batch processor, O(n) concurrent operations, memory scales with batch size, error propagation needs review.
