What it reports

Catch clause with ignored error variable at line {line}. Using '_' as the catch binding signals the exception is intentionally discarded. AI-generated code often silently suppresses errors this way, hiding failures in production. Either log the error, re-throw with context, or add an explicit comment explaining why suppression is safe here.

Flagged

try { risky(); } catch (_e) { fallback(); }

Not flagged

try { risky(); } catch (error) { report(error); }

Pattern
