semble vs agent-bridge
semble: Semble is a high-performance code search library designed for AI agents, providing instant access to precise code snippets. It offers significantly faster indexing and querying compared to transformer models, achieving 99% of their retrieval quality while running entirely on CPU without external dependencies.; agent-bridge: AgentBridge uses a two-process architecture with a foreground MCP client (bridge.ts) and a persistent background daemon (daemon.ts). It enables bidirectional communication between Claude Code and Codex via a control WebSocket and proxy, with automatic reconnection and message loop prevention.
