LowFile-scopeRuby Plug & play

Remove redundant method calls

Avoid no-op or duplicate calls (e.g., flatten.flatten, compact followed by compact!).

Why this matters

Reduces noise and minor performance overhead.

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

Avoid

arr.flatten.flatten

Prefer

arr.flatten(2)

Bad

arr.compact.compact

Good

arr.compact!

From the same buckets as this rule.

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

Critical
Avoid Redundant `None` Comparisons
Identify cases where `x is None` or `x is not None` is used redundantly when `x` is always or never `None`. This may indicate a deeper logic issue.

High
Avoid Functions That Always Return the Same Value
Identify functions that return the same value regardless of input. This may indicate poor design or a logic error.
