Unused variable 'git_diff'
1def get_gpt_codex_prompt(diff, header=None, commit_type=None):

Description
An unused variable takes up space in the code, and can lead to confusion, and it should be removed. If this variable is necessary, name the variable _ to indicate that it will be unused, or start the name with unused or _unused.
Bad practice
def update():
for i in range(10): # Usused variable `i`
time.sleep(0.01)
display_result()
Preferred:
def update():
for _ in range(10):
time.sleep(0.01)
display_result()
