🕵️ Confusable Handle Detector

High-Stakes Handle Security

In an era of sophisticated social engineering, a username that looks like "apple" might actually contain a Cyrillic "а" or a hidden zero-width joiner. The Confusable Handle Detector is a specialized security tool designed for developers, community managers, and security researchers to audit strings for Unicode-based spoofing attempts.

What it does

This skill performs deep inspections on handles, brand names, and text lists to identify:

• Invisible Characters: Zero-width spaces and joiners that hide in plain sight.
• Homoglyphs: Look-alike characters from different scripts (e.g., Latin 'o' vs. Greek 'ο').
• Directional Overrides: RTL/LTR markers used to flip the display order of characters.
• Mixed-Script Detection: Identifying suspicious script switching within a single word.

Why use this skill

Writing your own regex to catch every Unicode edge case is error-prone and time-consuming. This skill leverages a pre-built Python scanner and a curated reference library to provide instant, structured auditing. It moves beyond simple "Is this valid?" checks to "Is this deceptive?", providing actionable remediation snippets that help you explain risks to users or stakeholders without sounding alarmist.

The Output

Each scan produces a detailed report covering the scope inspected, a categorized list of findings by severity, and specific remediation advice based on JustHandled Labs' audit checklist.
