Local Password Generator & Strength Check

This skill appears to do exactly what it says: locally generate passwords and estimate strength. The code is small and uses only Python standard libraries. Notes: (1) check.py has a minor bug path where calculating entropy may return 0 instead of the expected tuple if no character categories are detected, which can cause a runtime error for empty input — this is a correctness issue, not malicious behavior. (2) Entropy and crack-time estimates are heuristic (assumes 10B guesses/sec and approximates symbol count); treat them as guidance, not absolute guarantees. (3) As with any password tool, avoid running it on shared or untrusted machines if you will type or generate real sensitive passwords there, and do not paste generated/checked secrets into untrusted channels. If you want extra assurance, review the two scripts locally or run them in an isolated environment before use.
