Agents! Please? Wiki

score = 10
bonus = 5
total = score + bonus

Variables store values that later expressions and conditions can use. When reviewing a diff, check whether the agent changed the value being stored or replaced the variable used in a calculation.

if score >= 10:
    result = "pass"
else:
    result = "fail"

Conditions decide which branch of code runs. Small changes to comparison operators can completely change boundary behavior.

if has_key and door_open:
    enter = True

Logical operators combine multiple requirements. Review whether all required conditions should be true together or whether either condition is enough.

for item in items:
    total = total + item

Loops repeat logic across multiple values. Trace at least two iterations when a changed loop affects totals, counters, or accumulated results.

count = 0
for item in items:
    count = count + 1

Counters are commonly used to track how many times something happens. Their initial value and update position both affect the result.

def calculate_total(a, b):
    return a + b

Functions package reusable logic and return results to the caller. When a function changes, check both its internal calculation and the value it returns.

result = calculate_total(4, 6)

Arguments provide values to a function's parameters. Make sure the agent has not changed their order or passed a value that represents the wrong piece of data.

if value < 0:
    return 0
return value

A return statement ends the current function and sends a value back. Early returns are important because code below them will not run on that path.

input: 10
expected: "pass"

Tests let you compare expected behavior with what the reviewed code actually produces. Use more than one input when different conditions or branches are involved.

value = 10
if value >= 10:
    valid = True

Values exactly at a rule's boundary are especially useful for checking comparison logic. Testing just below, exactly at, and just above the boundary can expose subtle mistakes.
