Claude Code v1.0.113 13 Sep 2025

Improved Slash Command Validation

What changed: Character-level validation replaced path-prefix checking Details:

New NZ5() function at line 421329 validates command names contain only alphanumeric characters, colons, hyphens, and underscores
Replaces previous logic that checked for /var, /tmp, /private path prefixes
Provides more precise security validation
Evidence: Used at line 421356 instead of path checks at line 421220 in v1.0.112
