I've been exploring how to eliminate the "déjà vu in development" problem with deja-view - a semantic search tool built with Chroma that transforms GitHub issues into high-dimensional vectors. We've deployed it live to the Continue repo and I look forward to tackling parallels of open source development. The real game-changer comes when I get this integrated into our MCP to help identify issues current work will fix. Instead of just finding similar issues, you can now: discover semantically related problems → explore safely with Plan mode + MCP → understand context through AI file analysis → implement with full historical knowledge. This workflow turns Continue agnets from code generators into project historians who truly understand your codebase evolution. This represents the future of Continuous AI in software development - moving beyond keyword matching to semantic understanding. When AI can grasp not just what you're building, but what's been built before and why, we stop reinventing wheels and start building on the shoulders of our past solutions. The potential for automatic PR review enrichment and cross-repository semantic search is just the beginning. #ContinuousAI #vectorsearch #AInative

Semantic Search MCP Server Transforms GitHub Repository Access for AI Tools A developer has created a production-ready GitHub Semantic Search MCP Server that eliminates the need to clone repositories for AI code context, addressing specific limitations in tools like Cursor IDE. The system uses Cloudflare workflows to index GitHub repositories and provides semantic search capabilities through a live MCP endpoint accessible at https://lnkd.in/e3EpAnWy. The solution addresses a critical developer workflow issue where accessing recent code patterns requires manually cloning repositories since GitHub's search API is limited to public repos via Copilot chat and unavailable through GraphQL. The system supports both public and private repositories through GitHub token authentication, with indexing performance of approximately one hour per 1,000 files. Users can immediately access indexed repositories through their AI tools without local storage requirements. The technical implementation leverages Cloudflare's serverless infrastructure including D1 databases for workflow tracking, Vectorize for 384-dimensional cosine similarity searches, R2 buckets for tokenized code storage, and workflows for automated indexing. The system includes comprehensive metadata indexing for repository organization, branch management, and path-based filtering. Security considerations include RSA encryption for sensitive data at rest and self-hosting options for organizations with sensitive intellectual property. This implementation demonstrates practical serverless AI infrastructure that scales automatically while maintaining cost efficiency through throttled processing. The project establishes a replicable pattern for organizations needing semantic code search without the overhead of repository management. This showcases how Model Context Protocol can bridge existing development tools with cloud-native AI services, potentially transforming how development teams access and understand distributed codebases. 🔗https://lnkd.in/e2qeAHpW

#RAG can really boost code search and generation 💻✨ But, when dealing with large enterprise codebases, a reliable and accurate solution comes with its own set of challenges. This system, shown in the diagram, processes code files, breaks them into meaningful chunks, generates descriptive text, and creates vector embeddings for efficient searching. Moreover, it does this continuously to support code changes. A simple vector similarity search often gives irrelevant results upon a user's query, so a two-step retrieval process is better. First, an initial vector search is applied, followed by an LLM-based refinement to accurately rank the results based on the query's context. Note that proper code chunking is crucial because it affects the quality of the code snippets you get back. While chunking text is straightforward, chunking code is more complex and needs advanced techniques to keep the code's semantics intact. To address this, CodiumAI has developed a comprehensive indexing pipeline capable of handling the scale and complexity of enterprise code.  The system includes a dedicated splitter for different types of files, which is also extendable (!!) to enable different dev teams to adopt the system for their internal format and practices. By effectively managing the challenges of #indexing and retrieval, we aim to bridge the gap between powerful language models and the realities of enterprise development.

🔮 Building AI powered apps today looks very different today than what it used to. Weaviate lets you build AI powered applications by reducing the AI and ML problem into a data engineering problem which is something most companies already have competencies in. In storing your vectors in Weaviate, it allows you to extract features from your data set through AI powered vector search. This is what you're seeing in the video. 🔎 The idea of vector search is still a fairly new phenomenon for many technologists. Vector search is a capability powered by databases designed and dedicated to store vectors, like Weaviate. These databases are a type of information retrieval system that leverages the semantic relationship of words in the same way that LLMs like ChatGPT leverage the semantic relationships of words. Here's the high level logical steps that are executed in the code. ——— High Level Logical Steps ——— 🛠️ Set up the Python virtualenv and get dependencies 🔑 Get an OpenAI API Key and add it to .env 💽 Instantiate Embedded Weaviate with text2vec-openai module 💾 Define and create the Question schema 🏃♀️ Fetch Question objects and batch load into Weaviate while creating vectors 👀 Apply a semantic search looking for "biology" related entities 😊 Allow the user to enjoy the semantically similar results Notice how the results don’t contain the word biology in them but the results all contain biology related items, in this instance species and DNA. This is the power of vector search! Here’s some interesting observations I made while working through this code ——— Interesting Observations ——— 💪 Flexibility with Embeddings. Weaviate allows me to bring my own embeddings or to create them for me. 🔮 Magically create embeddings from several LLM providers including OpenAI, HuggingFace, AWS, Google, Azure, and more! 📦 Batch loading of data offers a clean way to import objects in batches which can improve data ingestion speed. 🔎 Vector search queries can be extended to filter for specific fields 😎 The workflow of storing your data is very familiar with schema creation and then data ingestion. 🎛️ You get full control on what fields are actually vectorized within the schema. 🧞 The search capability is powered by AI, and so integrating Weaviate into your own application brings AI capabilities to your app pretty easily. ✅ So that's the foundation of bringing AI powered search into your application and projects. Weaviate is run in production by many companies you must be familiar with, including StackOverflow and others. You can get my sample code here --> https://lnkd.in/gzC6thMg, which is an excerpt from the Weaviate Quickstart guide for Python client version 3. We have a version 4 python client already in the works, but it's in beta at the moment. Weaviate Python Quickstart --> https://lnkd.in/gZvi9beN Want to learn more or build a project?

Look not to #AI, but to our own institutional memory and data. This function used to be performed by senior engineering staff but they're all retiring or gone. This article discusses the limitations of large language models (#LLMs) like ChatGPT for engineering applications and presents Accuris' Engineering Workbench as a solution for organizations to leverage their own data effectively. Here are some of the key points: LLMs like #ChatGPT often provide inaccurate or shallow answers to engineering questions due to their training on general, publicly available data. Organizations have valuable internal data (documents, drawings, models, etc.) that LLMs can't access. Accuris' Engineering Workbench is a semantic search application designed to search and organize an organization's internal data. The product has been used successfully by organizations like the US Navy and NASA - National Aeronautics and Space Administration to find crucial Engineering Workbench can connect various internal systems (CAD, PLM, ERP, etc.) to provide comprehensive answers to complex operational questions. The tool is already in use by 900,000 design engineers and many large companies. Accuris (formerly known as IHS) also publishes millions of standards and has access to a vast repository of technical articles, books, and patents. The article suggests that mining an organization's own data can be more valuable for engineering applications than relying on general-purpose LLMs.
