Real-time credential auditing

Stop guessing if your user passwords hold up. The `score_password_strength` tool runs the zxcvbn engine directly against inputs to calculate actual entropy instead of relying on arbitrary rules. Windsurf reads the output and flags weak patterns instantly. You get the exact crack time estimates needed to prove your security posture to the team.

Automated security feedback loops

Stop telling users their passwords are too short. Use the feedback returned by `score_password_strength` to provide specific, actionable advice on why their choice is vulnerable. Windsurf integrates these suggestions into your UI flows. It shifts the burden from the developer to the user, ensuring better account hygiene without manual code changes.

Data-driven password validation

Replace static regex checks with combinatorial analysis. The `score_password_strength` tool identifies dictionary words, keyboard patterns, and l33t-speak substitutions that regex misses. Windsurf uses this data to gate your registration logic. You ensure every new account meets a minimum strength threshold before the system accepts the write request.
