crates/oxc_linter/src/rules/eslint/symbol_description.rs:14

• The new .with_help text reads like a complete sentence but is missing trailing punctuation (many existing with_help("Pass …") messages end with a period). Consider adding a final period for consistency/readability.

    OxcDiagnostic::warn("Expected Symbol to have a description.")
        .with_help("Pass a description argument to the Symbol()")
        .with_label(span)

crates/oxc_linter/src/snapshots/eslint_symbol_description.snap:3

• This snapshot header now includes assertion_line: 444, but other snapshot files in this directory typically only include ---, source: …, --- (e.g. crates/oxc_linter/src/snapshots/eslint_new_cap.snap). If this was added unintentionally by a different insta version/config, consider regenerating/normalizing the snapshot to avoid inconsistent metadata churn.

assertion_line: 444
