semble vs node9-proxy
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.; node9-proxy: Node9 is an execution security layer for AI agents that intercepts dangerous shell commands and tool calls in real-time. It features a multi-channel approval system (native popup, browser, Slack, terminal), a flight recorder for live monitoring, and an AI negotiation loop to guide safer behavior. It also includes DLP content scanning and shadow git snapshots for undo.
