Can I use this on upgradeable contracts?

This skill is specifically designed for non-upgradeable contracts. Using it on upgradeable contracts requires extreme caution regarding storage layout, which is outside the current scope of this skill.

Does this skill change the contract's public interface?

No. Safe-Refactor is strictly constrained to preserve all public and external APIs, ensuring that existing integrations and frontends continue to work perfectly.

Will it break my existing Forge tests?

No. A core requirement of the Safe-Refactor skill is that all existing tests must pass unchanged. If a change causes a test failure, the refactor is considered invalid.

What kind of code changes are permitted?

Permitted actions include renaming internal variables, extracting logic into private helper functions, and reorganizing code to follow style guides, provided they do not alter the contract's semantics.

Security & Testing

Refactors non-upgradeable Solidity contracts to improve clarity and maintainability while preserving identical execution behavior and interfaces.

Safe Solidity Refactor is a specialized capability designed for the structural cleanup of immutable smart contracts. It enables developers to reorganize code, extract internal helpers, and simplify complex logic without risking changes to state transitions, events, or external call behaviors. This skill is essential for preparing DeFi protocols for security audits or improving long-term maintainability after business logic has been locked and verified by a comprehensive test suite.

Key Features

01Extracts internal helper functions for better code modularity

02Renames variables and internal functions for enhanced readability

03Verifies all changes against existing Foundry test suites to prevent regressions

04Ensures zero changes to public/external APIs and custom error patterns

05Simplifies control flow and removes dead or unreachable code
