Build a just-in-time knowledge base with Amazon Bedrock

Traditional Retrieval Augmented Generation (RAG) systems consume valuable resources by ingesting and maintaining embeddings for documents that might never be queried, resulting in unnecessary storage costs and reduced system efficiency. This post presents a just-in-time knowledge base solution that reduces unused consumption through intelligent document processing. The solution processes documents only when needed and automatically removes unused resources, so organizations can scale their document repositories without proportionally increasing infrastructure costs.

.clinerules: Version-Controlled, Shareable, and AI-Editable Instructions

For some time, Cline offered two ways to provide persistent guidance: a simple "Custom Instructions" text box and the more robust, file-based .clinerules system. While the text box was a familiar starting point, it was always a stepping stone. Today, we're fully embracing the more powerful paradigm by deprecating the old Custom Instructions feature to focus entirely on .clinerules. The reason is simple: treating instructions as code is fundamentally better. A single, static text box doesn’t sca
