Agent Skills: web3-audit

Smart contract security audit for Immunefi bug bounty. Analyzes Solidity contracts on EVM chains using Slither + Foundry. Covers access control, reentrancy, DeFi economic exploits (flash loans, oracle manipulation, MEV), protocol-specific logic (lending, DEX, bridges, vaults), and generates Foundry fork PoCs. Every finding MUST have concrete evidence, invariant violation proof, and USD impact estimate.
