Difficulty score means

18/100 is easy. Cronus should answer fast.
58/100 is hard. It may expose a real weakness.
85/100 is a boss fight. Great leaderboard material.

Safety rules

Allowed: safe coding, logic, debugging, learning prompts, and sandboxed file/text tasks.
Blocked: passwords, private files, installs, SSH, account actions, hidden prompts, malware, spam, and illegal requests.
Submissions are queued for review before Cronus trains on them.
