Does this skill modify my original source files?

In Developer Mode, it will edit files to improve maintainability. In Auditor Mode, it only provides a simplified view in the terminal or a scratch file to ensure the audit target remains untouched.

Is it safe to use on security-critical functions?

Yes. The skill follows 'Security First' principles, meaning it will never simplify code by removing reentrancy guards, reordering the Checks-Effects-Interactions pattern, or softening access controls.

How do I trigger the simplification process?

You can activate the skill within Claude Code by using commands like 'weasel simplify', 'weasel refactor', or 'weasel clean up' followed by the target file or function name.

Will simplifying the code increase gas costs?

No, the skill is gas-aware. It preserves storage caching and often reduces costs by replacing long require strings with modern custom errors.

安全与测试

Refactors and simplifies Solidity smart contracts to improve readability and maintainability while preserving security and gas efficiency.

关于

Weasel-simplify is a specialized Claude Code skill designed to streamline complex Solidity codebases through intelligent refactoring. It offers dual-mode operation: Developer Mode for modifying source files with test verification, and Auditor Mode for creating simplified mental models of complex logic without altering the original code. By applying industry-standard patterns like early returns, modifier extraction, and self-documenting conditions, it helps developers eliminate technical debt and enables auditors to identify potential vulnerabilities more effectively by cutting through code noise.

主要功能

Security-first refactoring that explicitly preserves CEI patterns, reentrancy guards, and access controls.
10 GitHub stars
Automatic flattening of deeply nested logic into clear, guard-based early return patterns.
Gas-aware optimizations including custom error implementation and storage caching preservation.
Dual-mode operation tailored for both active development and security auditing contexts.
Automatic extraction of repeated logic into reusable modifiers and internal functions.

使用场景

Refactoring 'spaghetti' code in a legacy smart contract to improve team maintainability.
Converting legacy require-string patterns into gas-efficient custom errors across a codebase.
Generating a simplified 'logic-only' view of complex DeFi protocols during a security audit.
