unused-variables

To detect unused variables in Solidity smart contracts, you need static analysis to pinpoint unreferenced state variables, local variables, and function parameters. This Skill performs that code analysis to identify dead code and reduce maintainability issues.

When a return value from a Solidity function call is silently discarded, it often indicates missing error handling and potential logic flaws. This Skill identifies instances of discarded return values during static analysis to ensure all function outputs are handled as intended.

Yes, you can use this to audit Solidity code for dead code and unreferenced imports. The Skill flags declared but unreferenced elements and identifies unused imports to reduce code bloat and potential confusion in smart contracts.

The best way to check for unused function parameters in a smart contract is running static analysis on the contract code. This Skill identifies and reports function parameters that are declared but never referenced to address maintainability.

To analyze an attached Solidity file for unused variables, provide the file such as 'VaultContract.sol' to the Skill. It requires static analysis of the contract code to pinpoint undeclared or unreferenced elements and reports them directly.
