# Set environment variables with automatic validation:
export BASH_MAX_OUTPUT_LENGTH=40000  # Validates and caps if needed
export CLAUDE_CODE_MAX_OUTPUT_TOKENS=16000  # Validates with warnings

# Invalid values show warnings but don't crash:
export BASH_MAX_OUTPUT_LENGTH=invalid  # Warning: Invalid value "invalid" (using default: 30000)
export BASH_MAX_OUTPUT_LENGTH=100000   # Warning: Capped from 100000 to 50000
