Reentrancy vulnerabilities in Solidity occur when external calls allow attackers to re-enter a contract before state updates complete. This Skill automatically identifies reentrancy patterns and enforces the Checks-Effects-Interactions pattern to prevent them during development and auditing.

Common Solidity vulnerabilities include reentrancy, integer overflow/underflow, weak access control, front-running, and unsafe external calls. This Skill detects these issues automatically and suggests secure coding patterns like Pull Over Push and safe math operations.

Yes. This Skill automates security best practices specifically for DeFi smart contracts by enforcing secure patterns, validating access control, and detecting vulnerabilities during development, eliminating the need for entirely manual security reviews before deployment.

Checks-Effects-Interactions is a Solidity pattern that validates conditions first, updates state second, and makes external calls last to prevent reentrancy. This Skill generates and validates this pattern automatically within your smart contract code.

Detection identifies existing overflow/underflow risks in Solidity code; safe math prevents them through secure arithmetic operations. This Skill does both: it identifies vulnerabilities and enforces safe math patterns to harden your contracts against arithmetic attacks.

Automated auditing catches common patterns and known vulnerabilities in Solidity, but complex logic and edge cases may still benefit from expert review. This Skill handles routine security checks and best-practice enforcement, reducing manual review scope significantly.
