Ctxo vs rails-ai-context

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.; rails-ai-context: rails-ai-context auto-introspects your Rails app and provides context to AI assistants via MCP, saving tokens and reducing discovery overhead. It generates context files for multiple AI tools and offers 11 MCP tools with smart detail levels.
