Agentic Engineering for the Rest of Us

A Non-Developer’s Guide to Coding Agents

Don’t marry the model. Learn the four coding agents that matter and the habits that carry between them, so a provider’s bad week costs you an afternoon, not your workflow.

Section 1: The route

  1. Level 1: Chat bot

    You ask, it answers, you copy the useful bits.

  2. Level 2: Coding agent

    One agent in your project folder; you steer it and check what it did.

  3. Level 3: Parallel coding agents

    Several agents at once; you hand out the work and review it.

  4. Level 4: Agent orchestration

    Something runs the agents for you; you brief the system.

Each level stands on the one below, and you climb only when the work in front of you demands the next. Most readers never reach the top; that’s by design.

Section 2: The free sample

Cover of Agentic Engineering for the Rest of Us by Harry Munro
Fig. 2.1 The book, as it ships

The first three chapters, as PDF and EPUB, free. They set up everything that follows: where the words are going, what happened in June, and what a harness actually is.

  1. Chapter 1: From Vibe Coding to Agentic Coding

    Where the language is going, and what I learnt from a reader review that told me my last book’s details would date.

  2. Chapter 2: Eighteen Days

    The Fable 5 export-control saga as it happened, and why it makes lock-in a personal risk rather than an abstract one.

  3. Chapter 3: Harnesses

    The word nobody’s explained to you, the four personalities, and why I tell you to skip browser app-builders.

Section 3: Specifications

The details will date. The principles are sound.

So the book quarantines the perishable facts in dated Field Guides and teaches the parts that don’t move: how to brief an agent, how to check its work, how to hand over a task and walk away safely. The model underneath becomes a setting, not a commitment.

Read about the whole book

Harnesses covered, as of late 2026
Harness Its job Where you meet it
Claude Code Collaboration First: one good conversation, done properly
Codex Delegation Once you start handing work over
OpenCode Freedom Near the end, where portability is the point
Pi Control Near the end, where portability is the point

Section 5: Where the rigour comes from

Before the agents, there were models. The school began with discrete-event simulation in Python, and the discipline carries straight across: build it, test it, defend it.

Spreadsheets average away the chaos; licensed software hides it behind a seat fee. The courses teach you to build models in Python with SimPy that you own, understand and can defend.

Fig. 5.1 is not a video. It is a discrete-event model of a Saturday checkout, running live in your browser. Close a till; see what it costs.

Harry Munro, Chartered Engineer

Domain knowledge is the moat, not syntax knowledge. The durable asset in all of this is what you understand about your own field.

The school is run by Harry Munro, a Chartered Engineer who has worked in industry since 2011 and independently since 2021. He spent more than a decade building simulations for organisations including Transport for London and Anglo American, and these days consults on applied AI projects, which keeps him close to what actually works.

Section 7: Service record

What students and colleagues say about Harry’s simulation teaching.

Harry consistently impressed me with his mastery of both the technical side of simulation modelling and coding as well as the nuanced aspects of simulation project management. He possesses a rare combination of modelling expertise and a keen understanding of how to translate complex business needs into effective simulation models. His leadership, focus on results and exceptional communication skills make him an ideal person to learn from.

Rory Greig Research Engineer at Google DeepMind

Harry is simply a master of discrete event simulation and SimPy. I watched him build complex simulations from scratch, expertly separating the noise from what really matters. If you're thinking of learning from him; don't hesitate!

Natalie Murray Senior Modelling and Simulation Engineer

The School of Simulation Course is a straightforward one-stop shop for working with SimPy. Worth the money when you consider the time I saved by not learning from my own mistakes!
