semble vs bilig
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.; bilig: bilig is a headless workbook runtime for TypeScript. It allows Node.js services, agent tools, and serverless functions to use spreadsheet formulas and workbook state programmatically without a visual interface. It features formula evaluation, persistence, round-trip verification, and MCP support.
