Summary

AgentRAG currently documents the intended modular retrieval architecture well, but the repo is still README-only. The best first implementation milestone is a thin set of interfaces that define the retrieval pipeline shape.

Why this matters

Without a clear interface layer, later work on chunkers, embedders, retrievers, rerankers, and vector stores will drift quickly. A small protocol/abstraction layer would make the project direction concrete.

Proposed scope

• define the first core interfaces or protocols for chunking, embedding, retrieval, and reranking
• add a minimal pipeline composition flow that wires those stages together
• include one in-memory/example implementation for development
• document the intended stage boundaries in code and README

Acceptance criteria

• the repo contains a small but usable code skeleton for the retrieval pipeline
• interfaces are clear enough for later provider/back-end implementations
• one example demonstrates indexing + retrieval flow end to end
• README reflects the first implemented architecture

Notes

The goal here is not feature completeness. It is to establish a stable, modular starting point for the rest of the project.
