Short blurb: A printable guide to connecting Claude to your tools and your code, with Python examples and a safe, approval-first build. 31 pages, A4.

Full description

From using Claude to building with it.

This 31-page printable guide shows you how to connect Claude to other tools, package your know-how as reusable skills, delegate multi-step work, and call Claude from your own code, while keeping a person in control. It builds on Levels 1 and 2.

What you will learn

• How to decide what is worth automating, and how risky it is
• Connectors and MCP, and how to use them with the right permissions
• Packaging a repeatable method as a reusable skill
• Supervised delegation to agents, and working with Claude Code
• API fundamentals: keeping keys safe, your first requests, streaming, errors and cost
• Tool use and structured output, with validation
• Building and testing a small enquiry assistant where a person approves every reply
• Security basics for builders, including prompt injection

Also included: a 30-day builder plan with a tick-box tracker, 12 prompts for technical projects, a build checklist and a glossary.

Designed to be easy to follow: every box is colour-coded and carries a text label. Code appears in its own labelled boxes. No programming experience is needed for the first four chapters. The code starts in Chapter 5.

Format: PDF, A4, print-ready. 31 pages. Edition 1, November 2026. Instant download.

Good to know: this is an independent guide, not affiliated with or endorsed by Anthropic. The Python examples were checked for valid syntax but were not run against the live service, so test everything before real use. Using the Claude API is billed separately by Anthropic, and features, model names and prices change, so check their documentation. The guide teaches skills and makes no promises about income or results.
