LowFile-scopeRuby Plug & play

Remove dead code and unused methods

Delete unreachable branches and unused methods; rely on VCS for history.

Why this matters

Reduces maintenance cost and cognitive overhead.

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

Avoid

def old_impl; end # no callers

Prefer

# removed; tests ensure coverage of live paths

Bad

if false then ... end

Good

remove the branch entirely

Critical
Avoid Duplicating String Literals
Store repeated string literals in constants or variables to improve maintainability and reduce redundancy.

Critical
Avoid Empty Methods
Detect methods that have an empty body. If a method is empty, ensure that a comment is present explaining why it remains unimplemented.

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.
