Zero to Claude Certified Architect — Complete Exam Prep Series - Zero to Claude Certified Architect — Complete Beginner's Guide | Part 4: Subagent Config & Context

In Part 4 of Zero to Claude Certified Architect, we go from the conceptual coordinator-subagent model into actual implementation using the Claude Agent SDK. This video covers Task 1.3 — the final task in Domain 1's highest-yield cluster — and closes the loop on everything from Parts 2 and 3. Domain 1: Agentic Architecture & Orchestration carries 27% of your total exam score. If you master Tasks 1.1, 1.2, and 1.3, you've captured the largest single scoring block on the entire Claude Certified Architect (Foundations) exam. In this video you'll learn: ✅ Raw API vs Claude Agent SDK — what each does and when to use it ✅ Library vs Framework — why the SDK is a framework and what that means in practice ✅ The Task tool — the exact mechanism for spawning subagents ✅ Why allowedTools must include "Task" — the #1 most tested gotcha on the exam ✅ AgentDefinition — all 5 fields: name, description, system_prompt, tools, allowed_tools ✅ The minimum-tools design principle — why not every agent gets every tool ✅ Context passing — how the coordinator constructs Task prompts that include everything a subagent needs ✅ Structured metadata — source, URL, date, confidence — preserving attribution across agent handoffs ✅ Parallel vs sequential spawning — how the SDK determines which mode you're using ✅ Fork sessions — divergent exploration branches from a shared baseline ✅ Goal-oriented prompt design — what to specify and what NOT to specify for subagents ✅ 6 anti-patterns the exam actively tests (with the correct alternative for each) ✅ 8 exam takeaways to memorize before test day 🎯 Exam Coverage: → Domain 1: Agentic Architecture & Orchestration — 27% of exam score → Task 1.3: Configure subagent invocation, context passing, and spawning → Completes the Task 1.1 → 1.2 → 1.3 progression in Domain 1 This series is designed for complete beginners. No prior Claude experience required. Every concept is built from first principles with clear analogies and exam-focused takeaways. ⏱️ Timestamps: 0:00 — Quick Recap — Part 3 1:31 — Raw API vs Claude Agent SDK 2:40 — The Task Tool: How Subagents Get Spawned 3:59 — AgentDefinition: All 5 Fields 5:16 — Minimum-Tools Design Principle 5:54 — Context Passing: The Coordinator’s Most Important Job 7:01 — Structured Metadata in Task Prompts 7:41 — Parallel vs Sequential Spawning 8:52 — Fork Sessions 9:44 — Goal-Oriented Prompt Design 10:55 — 6 Anti-Patterns the Exam Tests 12:35 — 8 Exam Takeaways + What’s Next 🔗 Complete Series — Zero to Claude Certified Architect: ▶ Part 1 — Exam Blueprint & Study Plan (start here) ▶ Part 2 — Agentic Loops: Domain 1, Task 1.1 ▶ Part 3 — Multi-Agent Coordinator Patterns: Domain 1, Task 1.2 ▶ Part 4 — Subagent Configuration & Context Passing (this video) ▶ Part 5 — Multi-Step Workflows with Enforcement & Handoff Patterns (coming next) Keywords: Claude certified architect exam, Claude Agent SDK tutorial, AgentDefinition Claude, subagent configuration tutorial, context passing multi-agent, Task tool Claude SDK, parallel subagent execution, Claude certified architect foundations, domain 1 task 1.3, agentic architecture exam prep, multi-agent systems Python, Anthropic certification study guide, fork session Claude SDK, goal-oriented prompt design, AI agent exam prep 2025 #ClaudeCertified #AnthropicAI #ClaudeAgentSDK #MultiAgentSystems #AIArchitecture #AIcertification #agenticAI #claudeAPI #techcertification #studyguide
