Claude Step by Step Level 4 Expert

Level 4: Expert (Architect)

A printable guide to designing, measuring, securing and scaling systems built on Claude, with the judgement to know when not to. 29 pages, A4.

Full description

Design systems that keep working when things go wrong.

Experts don't know more tricks. They measure instead of guessing, constrain instead of hoping, and plan for failure. This 29-page printable guide gives you the frameworks and checklists to do that. It assumes you have built something small first (Level 3).

What you will learn

• The principles of production AI, and the quality, cost and speed trade-off
• Workflow and agent patterns, and how to choose the simplest one that works
• Context and tool design, including the basics of retrieval
• Evaluation: building test sets, graders and a release gate
• Controlling cost, speed and scale, with unit economics
• Reliability engineering and failing safely
• Threat modelling, privacy and governance for AI systems
• Treating prompts as versioned, tested assets
• Honest product and business thinking before you build for others
• Three worked design sketches to adapt

Also included: a 90-day roadmap with a tick-box tracker, an architecture decision checklist, a production readiness 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.

Format: PDF, A4, print-ready. 29 pages. Edition 1, November 2026. Instant download.

Good to know: this is an independent guide, not affiliated with or endorsed by Anthropic. The code samples were checked for valid syntax but were not run against the live service, and the prices in them are placeholders. Features, models and prices change, so check Anthropic's documentation. Reading a guide does not make anyone an expert, and this one makes no promises about income or results. It is general education, not professional engineering, security, legal or compliance advice.
