Q: Which is better, Ctxo or agent-shadow-brain?

By GitHub stars, Ctxo has more community adoption, but the best choice depends on your specific use case.

Ctxo: Ctxo indexes your codebase into a deterministic graph of symbols, edges, and git history, exposed through 14 semantic MCP tools. It enables AI agents to proactively understand code context, blast radius, and git intent, preventing common mistakes like missing inheritance or reintroducing bugs.; agent-shadow-brain: Shadow Brain is the first open-source shared memory and context system for AI coding agents. It allows multiple agents and sub-agents to share a common brain, with features like causal memory chains, dream engine, reputation ledger, and more. It works with 10+ agents and is free and local-first.
