UUIDGen
Generate UUIDs, short IDs, and nano IDs. Use when creating database keys, minting session tokens, generating unique filenames, or producing batch IDs.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/ckchzh/uuidgenUUIDGen
A real UUID generator and validator. Generate v4 UUIDs, batch-create multiple IDs, validate UUID format, extract UUIDs from text, and generate short 8-character IDs. Uses /proc/sys/kernel/random/uuid on Linux or falls back to python3 uuid module.

|---|---|
uuidgen v4 | Generate a single random UUID v4 (with compact, uppercase, and URN formats) |
uuidgen batch <count> | Generate multiple UUIDs (default: 5, max: 1000) |
uuidgen validate <uuid> | Check if a string is a valid UUID (shows version, variant, and format details) |
uuidgen extract <text> | Find and extract all UUIDs from a text string |
uuidgen short | Generate a short 8-character UUID (plus 3 alternatives) |
uuidgen version | Show version |
uuidgen help | Show available commands and usage |
Requirements
- Bash 4+ (
set -euo pipefail) - One of:
/proc/sys/kernel/random/uuid(Linux),python3, or/dev/urandom - No external dependencies or API keys
When to Use
- Generate database keys —
uuidgen v4for a single ID,uuidgen batch 100for bulk - Validate user-supplied UUIDs —
uuidgen validate <uuid>checks format, detects version and variant - Extract IDs from logs/text —
uuidgen extract "Error for session 550e8400-e29b-..."pulls out all UUIDs - Short identifiers —
uuidgen shortfor 8-char IDs suitable for URLs or display - Batch ID generation —
uuidgen batch 50creates 50 UUIDs numbered for easy reference
Examples
# Generate a single UUID v4
uuidgen v4
# Generate 10 UUIDs
uuidgen batch 10
# Validate a UUID
uuidgen validate '550e8400-e29b-41d4-a716-446655440000'
# Extract UUIDs from text
uuidgen extract 'User 550e8400-e29b-41d4-a716-446655440000 created session abc12345-dead-beef-cafe-123456789012'
# Generate a short 8-char UUID
uuidgen short
