A practitioner's field guide to working alongside intelligent systems without being hollowed out by them. Released chapter by chapter. This edition opens Chapter 4 and Chapter 5, with both worked appendices.
Introduction
Preface: Why I Wrote ThisAvailable
Fear is the default response to AI disruption, and deliberately refusing to let it steer is a skill that must be built - not assumed.
Part One - Yourself
Chapter 1: The World You're EnteringAvailable
The AI era does not destroy the value of human judgement - it clarifies it by removing everything below it, making the practitioner with genuine domain depth and self-knowledge more structurally powerful than ever.
Chapter 2: You Are Not a VariableAvailable
AI amplifies what you bring - the practitioner with genuine direction is multiplied while the variable who produces efficiently becomes progressively substitutable; the question of which you are has never had sharper consequences.
Chapter 3: Your Bias Is Your AssetAvailable
Your preferred domains of attention - the subjects you return to without instruction - are domain-specific assets to invest in, and in an AI era that commoditises surface breadth, that investment is the foundation of trustworthy evaluation.
Chapter 4: Your CreedAvailable
A creed is not an aspiration - it is the minimum viable operational conviction that tells you what to do when the situation is genuinely hard and the easier path is available, and it is found by examining what you have already refused, not by writing what you wish you believed.
Part Two - Your School
Chapter 5: Your SchoolAvailable
The quality of AI-assisted output is capped by the quality of the human judgement governing it - not by the capability of the tools - which means expanding the school without building the judgement first produces a liability that looks like productivity.
Chapter 6: Your ShoalSummer 2026
A Shoal compounds quality rather than multiplying output - the practitioner who builds a functional one earns a floor that keeps rising and a protection against passive drift that no individual school can provide.
Chapter 7: Your TreeAutumn 2026
The gap between knowing about something and knowing how to navigate it in consequence-laden conditions is the practitioner's durable moat - and it is built not by accumulating experience but by extracting from it.
Chapter 8: Through the Looking GlassAutumn 2026
The disorientation of the first weeks in a new role follows a predictable pattern, and the critical skill is learning to distinguish temporary calibration from a genuine values mismatch - because these two conditions require completely different responses.
Chapter 9: Navigating the CurrentsWinter 2026
A creed is not a statement about who you want to be - it is an instrument for reading the world accurately, and the practitioner who has one can distinguish calibration from a wrong sea, navigate ambiguity with direction, and recognise the right sea when it appears.
Closing: Your GenerationForthcoming
The qualities most needed in the AI era - self-knowledge, deliberate community, domain depth, holding one's creed under pressure - are the same qualities that have always determined whether practitioners shape their environments or are shaped by them.
Appendices
Appendix A: Creed Refinement Prompt ExampleForthcoming
First-draft creeds almost universally fail in three ways - aspirational behaviour clause, borrowed belief clause, and costless 'even when' - and the interrogation process's value is in refusing to accept any of the three, which requires discomfort before it produces a creed that actually holds.
Appendix B: Transparent AI Use in Education - A Process FrameworkForthcoming
The right institutional response to AI-assisted work is to make the process of thinking visible and assessable - not to detect AI use, which is unsolvable, but to require evidence of genuine intellectual engagement that AI cannot produce on the student's behalf.
Appendix C: The Practitioner's CovenantForthcoming
Self-knowledge as a practitioner requires active stock-taking at specific moments - starting a new role, when tools change, when operating on autopilot - because identity drifts in the absence of deliberate examination.
Appendix D: Things They Should Have Told You on Day OneForthcoming
The gap between official onboarding and the knowledge new starters actually need is nearly universal, and the practitioner who fills it - for themselves and others - demonstrates the book's core claim that what you build for others sometimes names you more clearly than any job title.
References: References and Further ReadingForthcoming
The intellectual foundations of practical wisdom - the two kinds of knowing, the conditions for expertise, the role of reflection, the structure of bias - converge across multiple independent research traditions, and the book's framework is grounded in that convergence rather than invented.
