Codebase Onboarding

Join a new team and get productive fast. This workflow combines analysis, interactive teaching, and documentation plugins to help you understand any codebase deeply, from architecture down to individual patterns.

4 Steps
01

Map the codebase

LAlegacy-analyzer

Scan the entire project to understand its architecture, dependencies, and key patterns. Legacy Analyzer produces a comprehensive map of modules, entry points, and how data flows through the system.

02

Deep-dive into key areas

LAlegacy-analyzer

Focus on the most critical modules identified in step 1. Understand business logic, data models, and integration points that you’ll need to work with day-to-day.

Interactive walkthroughs

CTcode-tutor

Use Code Tutor to get interactive, personalized explanations of complex code areas. Ask questions, get guided tours of tricky patterns, and build real understanding, not just surface familiarity.

04

Generate team docs

DGdoc-generator

Capture everything you’ve learned into well-structured documentation. Creates onboarding guides, architecture decision records, and module-level docs that help the whole team.

Getting the most out of this workflow

Start with /analyze-legacy --overview to get a bird’s eye view before diving into specific modules. This helps you understand the dependency graph first.

Use Code Tutor’s interactive mode to ask follow-up questions about patterns you don’t understand. It adapts explanations to your experience level.

Generate docs as you learn, this creates a knowledge base that benefits the next person who joins the team.
