Page: 'XLOOKUP Practice — Session 1'\n\nWorked through 6 practice problems from the sales table.\n\nProblem 1 (single condition lookup): got it right first try, no issues.\n\nProblem 2 (lookup with IFERROR wrapper): got it, but forgot the syntax order at first — put IFERROR outside instead of wrapping just the XLOOKUP part. Fixed it once I saw the error.\n\nProblem 3 (multi-condition, region + product): messed this up twice. Tried using two separate XLOOKUPs and couldn't combine them. Not sure how to actually do an AND-style lookup with XLOOKUP.\n\nProblem 4 (same as 3 but with dates added as a third condition): skipped this one, too confused after problem 3.\n\nProblem 5 (lookup returning multiple columns at once): got it, easier than expected once I saw you could return an array.\n\nProblem 6 (approximate match / nearest value): got the right answer but honestly just guessed the match_mode number, don't actually understand what -1 vs 1 means here.\n\nOverall feeling: comfortable with basic and multi-column lookups, still lost on combining multiple conditions in one XLOOKUP, and fuzzy on match_mode options.

Summary  
This chapter covers how to programmatically configure an AI agent by defining its system prompt, selecting and invoking tools, and enforcing a structured output format.  

General domain of usage  
Educational study tools

Let's build your first Tutor agent.

You just did this manually last section, read your own notes, pulled out what's understood vs. shaky, built flashcards. Now turn it into something you don't have to re-explain every time.



## What You're Building

An agent that reads your practice notes and always returns the same three things: what you've got, what's still confusing, and flashcards built from your real mix-ups — not a generic quiz. A sample practice notes page is already connected behind the scenes, so you can test a real agent without a real Notion account.



What kind of coach this is, not just "a helpful bot"

Actually check the real notes instead of guessing

Lock every answer into the same three sections

Don't call something "understood" just because the final answer happened to be right



Combined into one system prompt:

><b>You are a study notes coach. When the user references a practice notes page, use notion_page to load it before answering. Never answer from memory. Always return exactly these three sections, in this order: What You've Got (bullets), Still Confusing (bullets, quoting the specific line that shows it), Flashcards (3 to 5 question/answer pairs built from the real mix-ups). A correct final answer doesn't count as "understood" if the notes say it was a guess — flag those under Still Confusing too.



> ## Task
> 1. Click "Create Agent."
> 2. Agent name
>    ><b>Study Notes Coach
> 3. System prompt → paste the block above exactly 
> 4. Choose tools → check Notion Page
> 5. Save, then activate the agent for this chapter
> 6. Send: 
>    > <b>Read my XLOOKUP practice notes and give me what I've got, what's still confusing, and some flashcards.`
> 7. Check your result: Problem 6 in the notes says the learner got the right answer but "honestly just guessed the match_mode number." If your agent lists match_mode under What You've Got just because the final answer was correct, that's a real miss — go back and tighten the constraint.

Get hands-on experience with building a personal AI learning system using Claude, from mapping your skill gaps and writing structured prompts to building agents that read your notes and scores and recommend what to study next.

Discover how to set up a personal learning workspace, define a specific skill map for what you want to learn, and run a quick diagnostic to see exactly where you're starting from.

Explore the essentials of writing structured prompts with context, instruction, format, and constraint, then practice the same skill through quizzes, explain-it-back exercises, and real-world scenarios.

Get hands-on experience with Claude tools like notion page and spreadsheet analyze, then build single- and multi-tool agents that read your notes and scores to recommend what to study next.
