Level 2 · Intermediate — Primwright: Applied AI Systems
An Intermediate Guide to Building, Connecting, Evaluating, and Securing AI Applications
The second level of the Primwright progression — for readers who have completed Foundations and are ready to build with AI: connecting systems, evaluating behavior, and securing what they ship.
What the level covers.
- Translate a user need into requirements, boundaries, acceptance tests, and a fallback.
- Version prompts and context as application components.
- Validate syntax, schema, and business rules.
- Read and modify a small Python/API workflow.
- Build semantic search and a small RAG system.
- Define narrow tools, approvals, and safe stops.
- Implement or simulate one bounded agent loop.
- Create evaluation datasets, rubrics, and regression tests.
- Threat-model injection, exposure, and unsafe tool use.
- Instrument a prototype with useful logs and traces.
- Present evidence, limitations, residual risk, and next steps.
Building
Applying the judgment from Foundations to systems you construct — not just tools you use.
Connecting
Joining AI capabilities to real workflows, data, and software — the seams where most failures live.
Evaluating
Measuring what your systems actually do — with rubrics, tests, and documented limits.
Securing
Protecting what you ship — the practical security posture of AI applications.

Who it's for.
Readers who have completed Foundations — who can understand, use, and verify AI — and are ready for the next step: applying that judgment to real systems they build, connect, evaluate, and secure.
Prerequisites.
- Book 1 (Foundations) — each level assumes the last; none can be skipped.
- Not required: Python, command-line fluency, paid subscriptions, prior API use, advanced mathematics, or model-building experience.
What you get.
Every level pairs a book with a course. The book is the curriculum — the complete text and the standard of evidence. The course is the guided path through it — sessions, knowledge checks, and capstone work.
