Building Scout

A plain-English guide to AI agents, and the tools that build them

Build a working AI research assistant, even if you've never written code.

Free as a PDF or EPUB. Or try the demo.

Three friendly robots from the book's cover, joined by branching lines: a team of AI agents.

The book covers AI agents, tools, prompts, hooks, subagents, skills, MCP, LangGraph, long-running harnesses and autoresearch.

What you'll build

Scout: your own AI research assistant

Ask it a question, and it comes back with a short report you can trust. You'll build every part of it yourself, one chapter at a time, by directing Claude Code.

  • A team of AI agents researches any question

    A planner splits your question up, researchers work on the pieces at the same time, and a writer pulls it all together.

  • Every claim is cited

    Each point in the report links to where it came from, and a fact-checker reviews the report before you see it.

  • It ends up live on the internet

    By the last chapter, Scout runs on its own web address that you can share with anyone.

How it works

Watch Scout think

Scout isn't one AI doing everything. It's a small team, and each member has one job. Pick a question and watch them work. This is an animation of what happens; to watch Scout's real runs, step by step, try the demo.
