LowFile-scopeRuby Plug & play

Use descriptive variable names

Prefer intent-revealing names over cryptic abbreviations.

Why this matters

Improves readability and reduces misunderstandings.

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

Avoid

r = Repo.new(u)

Prefer

report = ReportBuilder.new(user)

Bad

c = calc(x)

Good

count = calculate_total(x)

From the same buckets as this rule.
