Security analysis

Caution
Quality score85/100

The skill uses the thefuck tool to automatically correct bash errors, which can potentially apply destructive fixes without review. While the skill itself is not malicious, the automated execution poses a risk of unintended system changes.

Findings
  • Automatically runs `fuck --yeah` without user confirmation, which could execute unintended commands based on the previous error.
  • Uses Bash with a third-party tool (thefuck) that can apply potentially dangerous fixes if the previous command was destructive.
