Claude-Code

What this is about # Domain 2 — Tool Design & MCP Integration — is 18% of the Claude Certified Architect – Foundations exam, across five task areas: designing tool interfaces, structuring error responses, distributing tools across agents, integrating MCP servers, and choosing built-in tools well. It’s a lighter domain than Agentic Architecture, but arguably the most immediately practical one — every point here shows up the first time you give an agent a tool that doesn’t work the way you expected.

What this is about # Domain 3 — Claude Code Configuration & Workflows — ties Prompt Engineering & Structured Output for second-heaviest domain on the Claude Certified Architect – Foundations exam, at 20%. Its six task areas are all about how you set up and drive Claude Code itself: configuration file hierarchy, custom commands and skills, conditional rules, choosing plan mode vs. diving straight in, iterating well, and wiring Claude Code into CI/CD.
