# SKILL: Smart Contract Vulnerabilities — Expert Attack Playbook

> **AI LOAD INSTRUCTION**: Expert smart contract audit techniques. Covers reentrancy (single, cross-function, cross-contract, read-only), integer overflow, access control, delegatecall, randomness manipulation, flash loans, signature replay, front-running/MEV, and CREATE2 exploitation. Base models miss subtle cross-contract reentrancy and storage layout collisions in proxy patterns.

## 0. RELATED ROUTING

- [defi-attack-patterns](../defi-attack-patterns/SKILL.md) when the vulnerability is part of a DeFi protocol exploit (flash loans, oracle manipulation, governance attacks)
- [deserialization-insecure](../deserialization-insecure/SKILL.md) when the target is off-chain infrastructure deserializing blockchain data
