Agentic-Architecture

What this is about # Claude Certified Architect – Foundations is Anthropic’s certification for designing Claude systems, not just using them. Where the Claude Certified Associate exam tests whether you can operate Claude with professional discipline — good prompts, sound judgment on output, the right entry point for the job — the Architect exam tests something a level up: can you design the agentic system, the tool integrations, and the configuration that other people build on top of. The ideal candidate has 6+ months of hands-on experience building with the Claude API, the Claude Agent SDK, Claude Code, and Model Context Protocol (MCP) — this isn’t a first certification, it’s the next one.

What this is about # Domain 1 — Agentic Architecture & Orchestration — is the single heaviest domain on the Claude Certified Architect – Foundations exam, worth 27% on its own. The exam guide breaks it into seven task areas: the agentic loop, multi-agent orchestration, subagent configuration, multi-step workflows, SDK hooks, task decomposition, and session management. That’s a lot of ground, so this post condenses it into the five ideas that actually carry the weight, with the smaller two folded into a quick round-up at the end.
