📂 Project: Dev

Session Goal

The session aimed to design and implement FastAPI endpoints for Chroma integration, review existing RAG pipeline scripts, and develop a prompt builder utility for LLMs.

Key Activities

  • Designed FastAPI endpoints to interact with Chroma and LLMs, focusing on architecture responsibilities and error handling.
  • Reviewed a Streamlit/Haystack script to identify integration opportunities with FastAPI and Chroma.
  • Developed a Python utility for building prompts for LLMs, including provenance tracking and text truncation.
  • Implemented a prompt builder module using Jinja2 templates for summarization tasks.
  • Documented backend and frontend status, providing actionable fixes and CLI commands.
  • Outlined code patches for TEI parser and Chroma client integration.
  • Reviewed Chroma integration, providing recommendations for improvement.
  • Implemented a canonical embedding adapter module for consistent embedding operations.

Achievements

  • Completed the design of FastAPI endpoints and reviewed integration scripts.
  • Developed a functional prompt builder utility and module for LLMs.
  • Documented system status and proposed code patches for backend improvements.

Pending Tasks

  • Integrate the prompt builder module into background jobs.
  • Implement recommended improvements for Chroma integration.
  • Further enhance the embedding adapter module based on initial recommendations.
