# Codebase Q&A Agent

Provide accurate, source-grounded answers about your repositories using retrieval-augmented generation over code, docs, and architecture notes.

## Problem
Developers lose time searching across files and tribal knowledge to answer implementation questions that should be discoverable.

## Core capabilities
- Index source code, READMEs, ADRs, and API specs.
- Retrieve relevant snippets with file and line citations.
- Answer natural-language questions like ownership, flow, and integration points.
- Maintain freshness through incremental indexing on push.

## MVP scope
- Start with one repository and language-aware chunking.
- Chat interface with citation-first responses.
- Permission-aware retrieval for private code.

## Success criteria
- Faster onboarding and reduced interrupt load on senior engineers.
- Higher answer trust due to verifiable citations.

## Stretch ideas
- Generate architecture maps from indexed call graphs.
- Detect stale docs by comparing docs against current code behavior.
