Uuid Generator

Generate UUIDs in versions v1, v4, and v5 with options for count, namespace, name, and output format.

Security Scan

The skill's code and runtime instructions are consistent with a simple UUID generator; nothing indicates unexpected credential access, network exfiltration, or inappropriate privileges — only minor functional bugs and privacy-relevant behavior (UUID v1) to be aware of.

Purpose & Capability

Name/description match the included script: the code generates v1, v4, and v5 UUIDs and supports basic output formats. There are no unrelated binaries, env vars, or config paths requested.

Instruction Scope

SKILL.md usage examples refer to a 'uuid' CLI; the repository provides scripts/uuid_gen.py (no wrapper). The README mentions 'custom patterns' and 'urlsafe' formatting; the script does not implement custom patterns and the 'urlsafe' branch uses a non-existent u.urlsafe() API (falls back to removing dashes). These are functional inconsistencies (bugs), not evidence of hidden behavior.

Install Mechanism

No install spec — instruction-only with a local script. Nothing is downloaded or installed automatically.

Credentials

No environment variables, credentials, or config paths are requested. The skill does use uuid.uuid1(), which embeds timestamp and the host's MAC address (privacy risk), but this is expected for v1 UUID support.

Persistence & Privilege

Skill is not always-enabled, does not request elevated or persistent privileges, and does not modify other skills or system settings.

Assessment

This skill is internally coherent for generating UUIDs, but check three things before use: (1) UUID v1 contains time + the machine MAC address and can leak host-identifying info — prefer v4 if you want no host fingerprinting; (2) the SKILL.md examples assume a 'uuid' CLI but the shipped file is scripts/uuid_gen.py — you may need to create a wrapper or run the script directly; (3) there's a minor bug: the 'urlsafe' formatting branch references a non-existent u.urlsafe() API and effectively falls back to removing dashes. Review/run the script locally (offline) to confirm behavior before integrating into automated workflows.

Generate UUIDs in various formats. Supports UUID v1, v4, v5, and custom patterns.

Features

• UUID v4 (default): Cryptographically random UUIDs
• UUID v1: Time-based UUIDs with timestamp and MAC address
• UUID v5: Namespace-based deterministic UUIDs (SHA-1)
• Bulk generate: Generate multiple UUIDs at once
• Format options: Standard, uppercase, no-dashes, URL-safe

Usage

uuid
uuid v4
uuid v4 --count 10
uuid v1
uuid v5 ns:url "https://example.com"
uuid --format no-dashes
uuid --format uppercase

Parameters

• version: UUID version to generate (v1/v4/v5, default: v4)
• count: Number of UUIDs to generate (default: 1)
• namespace: (v5 only) Namespace: url, dns, oid, x500, or custom
• name: (v5 only) Name within the namespace
• format: Output format: standard/uppercase/nodashes/urlsafe
