default-visibility

What problem does it solve?

This Skill addresses the security risks associated with functions and state variables in Solidity smart contracts that are declared without explicit visibility specifiers, which can lead to unintended public access or internal data exposure.

Core Features & Use Cases

• Identifies Missing Visibility: Detects functions and state variables lacking explicit public, external, internal, or private keywords.
• Contextual Analysis: Considers Solidity version and the nature of the function/variable (sensitive operations, data) to assess risk.
• Use Case: Auditing a Solidity contract to ensure that sensitive functions like transferOwnership or critical state variables are not inadvertently exposed due to default visibility rules.

Quick Start

Analyze the provided Solidity code for any functions or state variables missing explicit visibility specifiers.
