DeepSeek Harness (DSH) Plugin: CDK Best Practices Service

`xby-awslabs-cdk` is an AWS CDK plugin for DeepSeek Harness that addresses common developer challenges, including a lack of best-practice guidance, cumbersome compliance checks, and difficulty discovering architecture patterns. As an MCP Server, it provides features such as CDK best-practice recommendations, Nag rule explanations, architecture pattern lookup, and Lambda layer documentation. By configuring an API key, developers can quickly obtain compliance remediation steps and solution patterns during conversations. Note that some features, such as Nag suppression checks, have been deprecated; consider the AWS IaC MCP Server as an alternative.
