Usage Guidance
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.
Capability Analysis
Type: OpenClaw Skill
Name: u
Version: 1.0.0
The skill bundle is a standard collection of developer utilities including unit conversion, UUID generation, and data formatting. The implementation relies on native Node.js modules (like 'crypto') and custom logic without any external dependencies or high-risk system calls (no network, file system, or shell execution). All modules, such as 'passwordGenerator.js' and 'hashCalculator.js', perform their stated functions transparently, and the 'SKILL.md' contains no evidence of prompt injection or malicious instructions.

Capability Assessment
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.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install u - After installation, invoke the skill by name or use
/u - Provide required inputs per the skill's parameter spec and get structured output
