cem vs octocode

cem: `cem` is a versatile command-line tool designed to generate, query, and manage Custom Elements Manifest files, facilitating rich metadata for web components. It offers advanced features like a Language Server Protocol (LSP) for intelligent IDE support, a development server with live reload, and an AI-native Model Context Protocol (MCP) for component understanding and HTML generation.; octocode: Octocode is an agentic research platform that provides AI agents and developers with comprehensive code context from local workspaces and external sources like GitHub. It offers a suite of 13 tools, powered by a fast Rust engine, to enable evidence-first code understanding, review, and modification.
