Codebase Onboarding Agent: New Engineer Ready in Hours, Not Weeks
An AI agent that reads your codebase, generates an interactive onboarding map, and produces a tailored ramp plan.

<!--tl&dr-->
**TL;DR:** Read your codebase, generate an interactive onboarding map, identify the high-leverage files every new engineer needs to read first — all from a single CLI command.
<!--/tl&dr-->
The 10-Second Pitch
- **What it is:** A codebase analysis agent that produces an interactive onboarding guide from a git repo.
- **Who it's for:** Engineering managers, platform teams, any org with onboarding debt.
- **Why it matters:** Onboarding friction compounds. Every engineer who takes 2 weeks instead of 2 days to become productive is a tax on team output.
- **Stack:** Node.js, reads git history and source files.
Setup Directions
Prerequisites
- Node.js >= 18
- A git repo with at least 50 commits
Step 1 - Install
npm install @mrtech/codebase-onboarding --save-dev
Step 2 - Generate
npx codebase-onboarding generate --repo ./ --out ./onboarding/
Step 3 - Open Dashboard
npx codebase-onboarding serve --port 3002
Pros / Cons
| Dimension | Rating | Notes |
|---|
| **Speed** | 5/5 | Full map in under 2 minutes |
| **File Ranking** | 4/5 | Git history + AST analysis surfaces key files |
|---|
| **Interactive Output** | 4/5 | HTML dashboard with navigable dependency graph |
|---|
Verdict
Codebase Onboarding addresses onboarding debt directly. The dependency graph visualization alone is worth the install. Re-run it quarterly or after major refactors.
