Skill based on Aderyn (Cyfrin/aderyn), generated 2026-02-24.

Aderyn is a Rust-based Solidity static analyzer that finds vulnerabilities and code-quality issues. It supports Foundry and Hardhat with no config, optional aderyn.toml for path and detector control, and an MCP server for AI/editor integration. This skill focuses on agent use: CLI, configuration, detectors, report outputs, and MCP tools.
