Which one should I pick for a new project?

I can only answer questions about affaan-m/everything-claude-code or koajs/koa.

To help you decide between these two repositories for a new project, I need to understand your use case better. Here's what the repository data tells us:

koajs/koa (from the repository data shown):

• A Node.js web framework focused on HTTP request/response handling
• Provides Context, Request, and Response objects for middleware
• Includes query string parsing, error handling via ctx.throw(), and request/response manipulation
• The test suite shows it's a mature, well-tested library for building HTTP servers

affaan-m/everything-claude-code (from the repository data shown):

• Described as "The agent harness performance optimization system" for Claude Code, Codex, and similar tools
• Claims to focus on "Skills, instincts, memory, security, and research-first development"
• The repository data doesn't show actual source code structure, just the README

The choice depends on your goal:

• If you're building a web server or HTTP API, use koajs/koa — it's a proven web framework with clear abstractions for handling requests
• If you're building agent tooling or AI code optimization systems, consider affaan-m/everything-claude-code — though the README excerpt doesn't provide enough code visibility in the data shown to assess implementation details

Can you clarify what kind of project you're building?

• Is this for AI agent tooling or traditional backend?
