Internal engineering copilot

An agent over internal repos and docs that scaffolds code, runs retrieval-grounded reviews, and drafts design notes without leaving the IDE.

Engineering · Stack: Claude CLI, Cursor, Python, RAG. Outcome: Design-to-first-PR time down ~40%

Overview

An in-IDE copilot grounded in your own repos and docs that scaffolds code, reviews it against internal context, and drafts the design notes.

The problem

Generic AI assistants don't know your codebase, so engineers still spend the slow early hours wiring up context, conventions and design before the first PR.

How it works

• Indexes internal repos, docs and conventions into a retrieval layer.
• Scaffolds new code that follows the team's existing patterns.
• Runs retrieval-grounded reviews against internal standards.
• Drafts design notes from the change without leaving the editor.

What it does

• RAG over private repos and docs
• Pattern-aware code scaffolding
• Grounded code review against internal standards
• Auto-drafted design notes in the IDE

Architecture

Claude through the CLI and Cursor, with a Python retrieval layer (RAG) over the internal codebase.

Results

• Design-to-first-PR time down ~40%
• New code that matches house conventions
• Less context-loading before real work starts
