Deep Context

A Data Divers LLC game

Study for the Claude certs from a dive boat!

Every dive is a client job. You plan the Claude build, Tide the reef shark sends you down, and the water shows you what your plan does. Then the debrief scores each decision against an objective from the exam guides. The deeper you go, the closer you get to Architect Professional.

The Deep Context dive plan: a client brief for Saltline Cable from Tide the reef shark, three choices for how the report gives the break time, and a yellow Dive button, under a route strip reading 1,050 m offshore

Inside the dive

Straight off the live beta, one job in The Trench from plan to debrief.

Built from the exam guides

Every decision in the game is tied to an objective from the public exam guides. Every objective in all three guides shows up in the dives or the Field Guide:

Claude Certified Developer Foundations (CCDV-F) 25 of 25 objectives
Claude Certified Architect Foundations (CCAR-F) 30 of 30 objectives
Claude Certified Architect Professional (CCAR-P) 38 of 38 objectives

How it works

No account

Open it and dive. Your progress saves in your browser.

8 reaches, House Reef to The Surface

The Pod, The Ascent and The Surface are Professional work. The rest cover the Foundations material.

The Logbook

An estimate for each exam on its own 100 to 1,000 scale. Only your first try at each decision counts, so a re-dive teaches without padding the number.

The Field Guide

58 recall cards with three answers each. Miss one and it comes back before the sitting ends.

Pick your exam

Developer Foundations, Architect Foundations or Architect Professional. The route marks where your exam's material ends, so you know when you can stop.

The Drill Pool

64 short drills off the route, one exam objective each. Weakest First puts the objectives with the fewest first-try rights on top.
