A frame to help you reason through the assignment — concepts, diagrams, and the API map. It deliberately does not contain the answers or filled-in activity code. Instead it gives you the questions to ask yourself and the method to get there. The work — and the learning — is in running the cells, reading the decision tables / cache timings / the A2A trace, and writing your own conclusions.
Session shape: THREE independent parts — two notebooks + a runnable
a2a/mini-project. The notebooks are fully worked (no blanks to fill): your job is to **run them, keep the outputs

Session 11 Cheat Sheet — Claude Code & the Claude Agent SDK
A frame to help you reason through the assignment — concepts, diagrams, and the API map. It deliberately does not contain the answers or filled-in activity code. Instead it gives you the questions to ask yourself and the method to get there. The work — and the learning — is in building the app with Claude Code, reading the message stream, and writing your own conclusions.
Source:
11_Claude_Code/README.md(markdown-only session — no notebook; you write your Q1–Q4 answers directly in the README). Guides:01_Installing…,
A companion to the four session guides (README.md, 01_Installing_Claude_Code.md,
02_Using_Claude_Code.md, 03_Claude_Agent_SDK.md). It's a validation log: every
command and API call in those guides was checked against the official Claude Code /
Claude Agent SDK docs (and against the real installed SDK), so you don't lose time on a
stale flag or a wrong field name. Use it as a "known-good" reference while you install,
drive Claude Code, and wire up the agent. All the doc links you'll want are collected in
References.

Session 10 · LLM Servers — A Learning Journey
A step-by-step companion to
README.mdandENDPOINT_SETUP.md. Walk this alongside the assignment, not instead of it. Each step tells you what you're doing, why it matters, what will bite you, and the lesson to carry forward. The README asks you to answer the questions and build the app — this journey helps you understand what you built.

Session 9 Cheat Sheet — Agent Servers
A frame to help you reason through the assignment — concepts, diagrams, and the API map. It deliberately does not contain the answers or filled-in activity code. Instead it gives you the questions to ask yourself and the method to get there. The work — and the learning — is in packaging the agent, inspecting a Studio/LangSmith trace, shipping it, and writing your own conclusions.

Session 8 — MCP Learning Journey (Layered Edition)
What this is. A client-first, problem-driven path through the Cat Shop server. Instead of building the finished server bottom-up, you start with the smallest thing that works — one tool and a local client you write yourself — and add one capability per layer, each because you hit a wall the previous layer couldn't pass. Every layer ends with a command you run to validate it, and a diagram that grows as the system does.
Two editions, pick your style. This is the companion to
08_MCP_LEARNING_JOURNEY.md(the Build-From-Scratch edition, which reconstructs every server file top-to-bottom). They teach the

A frame to help you reason through the assignment — the concepts, diagrams, and API map. It deliberately does not contain the answers or a filled-in tool. Instead it gives you the questions to ask yourself and the method to get there.
