Gatekeeper Codegen

Use this tool to generate standardized, security-reviewed code snippets implementing the SLAMai Gatekeeper Pattern, including a Solidity modifier and Node.js verification logic. It accepts inputs chain (target EVM chain name), threshold (integer reputation score 0-100), and framework (Hardhat or Foundry, optional with default Hardhat). Based on these inputs, you must synthesize production-ready integration code for the chosen environment while following the pattern conventions. The returned output must strictly validate against the system-provided structured output schema for this tool, with correct types and no extra fields.
