Onboard new developers in days, not months
A new hire shouldn’t need three months and a dozen interruptions to learn how your systems fit together. ContextDx turns your codebase and docs into a living architecture map they can question from day one.

The onboarding problem
A new developer lands in a codebase nobody has time to walk them through. They learn by interrupting whoever’s nearest — and every question is an architect’s afternoon. Now two people are slow instead of one.
“I spent my first month just figuring out how the services actually talk to each other.”

Why a wiki and a buddy aren’t enough
The two usual answers each have a hole.
A wiki + a buddy
Onboarding docs are stale by the time they’re read, and the “buddy” is a senior engineer you’ve just pulled off their own work. Understanding still transfers one interruption at a time.
ContextDx
A living architecture map the new developer queries themselves — system, domain, component — so they see how it fits before they touch a file, without booking anyone’s afternoon.

Point Board Builder at the repo
Board Builder is a Claude Code plugin for VS Code. It reads the codebase and docs — across 7 languages — and builds the map, with no manual diagramming.
Hand over layered architecture boards
Every component is classified by archetype — APIs, services, databases, queues, infrastructure — and related semantically, so a new joiner sees the shape of the system, not a wall of files.
Onboard on reality, not a stale wiki
Incremental git-diff sync keeps the map matching the code, so the next hire ramps on how the system works today — not how it worked two years ago.
// ask it
What a new developer can ask on day one
Instead of interrupting a senior engineer, they ask the system — and get a focused board back.
- What are the entry points, and what does each one own?
- Which services touch the payments database?
- What breaks if I change the auth service?
- Where does an order actually go, end to end?
- Where do I start to add a feature to checkout?

Productive on a codebase they just joined.
First meaningful PR in week one, not month three. Point Board Builder at the repo and let new developers ask their first question.
