LowFile-scopeRuby Plug & play

Replace hardcoded values with named constants

Give semantic names to magic numbers/strings and freeze where appropriate.

Why this matters

Documents intent and centralizes change.

Side-by-side examples engineers can pattern-match during review.

Avoid

sleep 2

Prefer

RETRY_DELAY = 2.seconds
sleep RETRY_DELAY

Bad

if tries > 3

Good

if tries > MAX_RETRIES

Critical
Avoid modifying built-in prototypes
Detect modifications to built-in prototypes. Modifying built-in objects can lead to compatibility issues and unexpected behavior. Recommend creating helper functions instead.
