context-engineering vs semble
context-engineering: Context engineering is the practice of providing LLMs with comprehensive context from various sources. It emphasizes that quality and completeness of context matter more than prompt wording. This repository is a companion resource for a book on context engineering, containing examples and an online prompt builder.; 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.
