Headless password validation

Run `score_password_strength` as part of your CI pipeline to catch weak credentials before they reach production. It works over stdio or HTTP for easy integration. Claude Code executes the tool and returns the JSON result. You can pipe this output into your shell scripts to fail builds on weak passwords.

Combinatorial security analysis

The `score_password_strength` tool uses the zxcvbn engine to calculate entropy. It identifies dictionary words and keyboard patterns that standard regex checks ignore. Claude Code provides this analysis in your terminal. You get the exact crack time estimates needed for your security audits.

Automated feedback generation

Pipe the output of `score_password_strength` into your logs to generate reports on password health. The tool provides clear suggestions for every input. Claude Code automates this process without a GUI. It is built for engineers who need fast, reliable security verification in their terminal workflows.
