Security Scan

The skill is generally a harmless utility collection but the README/SKILL.md claims features (real-time currency rates, URL shortening/QR, clipboard, file hashing) that are not implemented and there are other inconsistencies — caution advised.

Purpose & Capability

The code modules match the stated high-level purpose (unit conversion, UUIDs, URL parsing, unicode tools, JSON/YAML formatting, hashing, password generation, color utilities). However several SKILL.md/README claims are not implemented in the code (real-time currency lookups, URL shortening/expanding, QR code generation, clipboard copy, file-hash routines, and README's npm package name differs from package.json). These mismatches reduce coherence.

Instruction Scope

SKILL.md and examples imply real-time currency conversion and features like URL shortening/QR generation and clipboard copying. The shipped JavaScript contains only static/hardcoded currency rates, no network calls, no URL-shortener/QR or clipboard code, and hash functions operate on strings (no file I/O). That discrepancy is scope creep/inaccuracy in documentation and could mislead users about actual behavior.

Install Mechanism

No install spec or external downloads; all code is included in the package and package.json has no external dependencies. This is low-risk from an install/download perspective.

Credentials

The skill requests no environment variables, no credentials, and references no config paths. There is no sign of credential or secret access in code.

Persistence & Privilege

Skill does not request always:true and does not attempt to modify other skills or system-wide settings. It has normal, non-persistent privileges.

What to consider before installing

This package appears to be a straightforward collection of local utility functions, but the documentation over-promises. Before installing or relying on it: 1) Note that currency conversion uses static hard-coded rates (not real-time) — do not use for financial decisions. 2) URL shortening/expansion, QR generation, clipboard copy, and file-hash features mentioned in SKILL.md are not implemented in the code. 3) UUID v5 and YAML conversion implementations are non-standard/simplified (may not be RFC-compliant). 4) README's install command references a different package name than package.json — packaging may be sloppy. 5) No networking or credential access is present, which is good; still review and test the functions in a safe environment and consider auditing or improving the missing/incorrect features before trusting them in production.
