Building it from scratch demonstrates deep technical mastery and practical LLM knowledge. - - Implementation Plan: - - **Ingestion**: Add a `/context ` REPL command that accepts local files (PDF, TXT, CSV). - - **Text Extraction**: Parse files into chunks (e.g., ~256 tokens per chunk) using existing dependencies or a lightweight library. - - **Embedding**: Use the `fastembed` crate to convert text chunks into vector embeddings locally (no API calls). - - **Storage**: Store embeddings in memory as a simple `Vec<(String, Vec)>` or use a lightweight vector DB like Qdrant for persistence. - - **Retrieval**: When the user asks a question, embed their query and retrieve the top 3 most similar chunks using cosine similarity. - - **Injection**: Prepend these chunks to the system prompt: `"Context: [Chunk 1] [Chunk 2] [Chunk 3]. Use this context to answer: [User Prompt]"`. - - **Configuration**: Add `enable_rag = true` option in `pymakebot.toml` to toggle RAG on/off. + Implemented in `src/rag.rs` with the `/context ` REPL command.
