What's Wrong?

Category: Code Quality / Learning from Corrections

Description:
Claude consistently adds inline import statements inside functions despite:

1. Module-level imports already existing for the same module
2. Being corrected multiple times in the same conversation
3. Previous discussions about multiprocessing/pickling issues caused by inline imports
4. Clear context that inline imports are problematic

Example from today's session:
# Module already has: import time (line 21)

# But Claude added inside worker function:
def process_flight_masks_worker(args):
import time # ← Added despite module-level import!
t_start = time.perf_counter()
# ...

Frequency: Recurring issue over months of use

Context: Python multiprocessing code, spawn context, module-level worker functions

What Should Happen?

Expected behavior:
Before adding any import, Claude should:

1. Check if module is already imported at file level
2. Only add inline imports when explicitly needed (dynamic imports, type checking, etc.)
3. Learn from corrections within the conversation

Frequency: Recurring issue over months of use

Context: Python multiprocessing code, spawn context, module-level worker functions
