WHY IT NEEDS A POLICY

Why upstash_redis_incr needs a policy

Incrementing a key modifies existing data in the Redis database. This is a write operation (it changes the stored value), but it is reversible (the value can be decremented or reset), so it does not qualify as Destructive. Misuse could corrupt counters or rate-limit logic, giving it medium severity.
