The Agent Skills Directory

[SAFE]: Audited the SKILL.md and documentation for prompt injection or malicious instructions. The content is purely instructional and descriptive of the FHEVM implementation.
[SAFE]: Reviewed references/hardhat.config.ts for hardcoded credentials. The file uses vars.get to safely retrieve mnemonics and API keys from the environment, providing benign placeholders for testing.
[SAFE]: Inspected the external dependencies in hardhat.config.ts. The packages used (e.g., @fhevm/hardhat-plugin, @nomicfoundation/hardhat-ethers, hardhat-deploy) are standard, well-known tools in the Ethereum development ecosystem.
[SAFE]: Analyzed the Solidity contracts (ConfidentialNFT.sol, EncryptedErrors.sol). The code follows established patterns for Zama's FHEVM, including proper use of euint8 types and access control through Ownable and FHE.allow.
[SAFE]: Checked references/README.md for hidden or malicious content. The file is encoded in UTF-16 format and contains a simple title, presenting no security risk.
[SAFE]: Verified the contract addresses in references/FHEVMConfig.sol. The addresses correspond to the official Zama FHEVM infrastructure on the Sepolia testnet.
