Preface Software development is entering a new phase. Generative AI has already made it possible to produce code, tests, documentation, and even complete applications at a speed that would have seemed unrealistic only a few years ago. But as many teams are discovering, faster generation does not automatically translate into better software. The bottleneck simply moves: from writing code to reviewing it, integrating it, securing it, governing it, and being able to explain who made which decision and why. This is the gap the book addresses. It is not a book about prompting tricks or about replacing developers with AI. It is about building a practical operating model for agentic software delivery: one in which humans define intent, constraints, and risk tolerance, while agents execute increasingly complex work within explicit boundaries. We refer to this model throughout the book as Hypervelocity Engineering (HVE). The journey starts with the transition from vibe coding to steered agentic development, where speed is preserved but ownership and accountability are restored. From there, we build the model layer by layer: the primitives that encode reusable engineering knowledge, the Research–Plan–Implement (RPI) cadence that keeps human judgment in the loop, the governance controls that move consequential actions toward deterministic execution, and the delivery loops that connect these elements into repeatable, increasingly autonomous systems. The emphasis is deliberately practical. The book uses repository-native examples, concrete agent roles, reusable prompts and skills, hooks, Model Context Protocol (MCP) integrations, governance patterns, and end-to-end use cases to show how these ideas fit together in real engineering workflows. It also looks beyond individual development tasks to the broader operating model: how teams coordinate multiple agents, how autonomy should be bounded, how evidence is preserved, and how long-running agentic work changes the experience of software delivery itself. The goal is not simply to help you generate more software with AI. It is to help you build a system in which AI-assisted delivery becomes repeatable, reviewable, secure, and ownable. By the end of the book, you should have a practical playbook for moving from isolated AI assistance toward a governed agentic engineering model that can be adapted to your own repositories, teams, and use cases.

Who this book is for This book is for technology leaders, senior engineers, architects, platform teams, governance professionals, and business stakeholders who want a practical operating model for adopting agentic AI in software delivery. A working understanding of modern software engineering concepts such as Git, pull requests, testing, CI/CD, and cloud-native development is useful, particularly for the hands-on examples. However, agentic development is still an emerging discipline, and many of the operating patterns described in this book are new even to experienced engineering teams. You do not need to arrive with an established methodology for working with agents; building that methodology is part of the purpose of the book. The business perspective is equally important. Agentic development changes not only how software is produced, but also how organizations think about capacity, cost, governance, accountability, and the division of work between humans and AI. For this reason, the book is also relevant to leaders who may not write code every day but are responsible for deciding where autonomy should be introduced, how value should be measured, and what controls must remain in place as software delivery becomes increasingly agent-driven. What this book covers Chapter 1, The Impact of AI: From Vibe Coding to "Steered" Agentic Development, explains how AI is changing the economics of software work, where vibe coding came from, why it works well for prototypes, and why it breaks down at enterprise scale. It introduces steered agentic development and Hypervelocity Engineering (HVE), together with a maturity model for assessing where an organization stands today. Chapter 2, Agentic AI and the New Way We Work, introduces the mental model behind agentic development. It explains what an AI agent is, how networks of agents collaborate, how human-agent responsibilities change as autonomy increases, and why developers increasingly act as directors of agentic systems rather than as typists. Chapter 3, Primitives: The Building Blocks of Agentic Development, shows how to move from one- off prompts to repeatable engineering. It introduces six core primitives—instructions, prompts, agents, skills, hooks, and Model Context Protocol (MCP)—and explains how they work together to encode engineering knowledge, boundaries, and reusable workflows close to the code.

Chapter 4, Reshaping the SDLC: Agentic DevOps and the RPI Cadence in Practice, applies those primitives across the software development life cycle. Using the FlowDesk scenario, it follows planning, design, development, testing, release, and maintenance, with the Research–Plan– Implement (RPI) cadence and Agentic DevOps acting as the through-line. Chapter 5, Governance: From Stochastic to Deterministic Agentic Development, focuses on the controls required to make agentic delivery governable. It introduces the stochastic-to- deterministic spectrum, instruction hierarchies, hooks, policy-as-code, decision boundaries, parallel-agent scoping, auditability, and the mapping of these controls to external governance frameworks. Chapter 6, Use Cases: Building Agentic Solutions with the HVE Primitives, brings the model together through three end-to-end scenarios: a travel agency built on agent handoffs, a conversational shopping assistant, and multi-channel marketing campaign generation. Each example shows how the paradigm, primitives, RPI cadence, and governance controls combine in practice. Chapter 7, Loop Engineering, moves from individual agent interactions to repeatable delivery systems. It explains how to design loops that can discover work, plan, execute, verify, recover, and complete tasks with bounded autonomy and explicit human approval points. Chapter 8, From Steered Delivery to Agent Experience, closes the book by bringing the HVE operating model together, comparing it with related work in the emerging Agentic SDLC discipline, and looking ahead to the human-agent experience of working with persistent, increasingly autonomous agents. To get the most out of this book You should be comfortable with the fundamentals of modern software engineering, including Git, repositories, pull requests, testing, CI/CD, and basic cloud application development. The practical examples use GitHub Copilot to illustrate agentic development patterns in a concrete, repository-native way. Some use cases also draw on Microsoft Agent Framework orchestration patterns and MCP integrations. Equivalent concepts can be implemented with other agentic development environments, although filenames, configuration formats, permissions, and runtime behavior may differ. For the hands-on sections, it is useful to have: A GitHub account and access to a repository where you can create branches, pull requests, and repository-level configuration files. Access to GitHub Copilot or another coding assistant that supports agentic workflows. • • • • • xiii Preface

1 The Impact of AI: From Vibe Coding to "Steered" Agentic Development Generative artificial intelligence (AI) has triggered a dual disruption across the software industry. First, it has redefined what organizations deliver, shifting the portfolio from traditional transactional applications to intelligent, AI-native experiences such as agentic call centers, conversational booking engines, and autonomous workflow assistants. Second, and just as profoundly, it has redefined how those applications are built. This chapter, as well as the rest of this book, focuses on the second dimension. For leaders and decision makers, understanding how software is produced today is a strategic imperative, and it demands a new playbook. The rate at which AI generates software can exceed an organization's capacity to review, govern, and maintain the resulting code reliably. Informal approaches such as vibe coding may produce impressive prototypes, but they begin to break down when software must be secured, integrated, audited, and supported at enterprise scale. The challenge, therefore, is not simply to generate more code, but to preserve the speed of AI-assisted development while restoring ownership, consistency, and accountability. This chapter introduces steered agentic development and Hypervelocity Engineering (HVE) as structured responses to that idx_ae8db2c2 hallenge. These approaches allow agents to idx_46563a30execute at speed while humans continue to define the constraints, make critical decisions, and remain accountable for the outcome.

This chapter covers the following topics: How generative AI is changing the economics of software development What vibe coding is and why it struggles at enterprise scale How steered agentic development divides responsibility between humans and agents The principles and foundations of HVE The HVE maturity spectrum and its assessment dimensions The primary risks organizations should address as they adopt agentic development By the end of this chapter, you will understand how AI is changing software production, why vibe coding does not scale reliably within enterprises, and how steered agentic development and HVE provide a more structured path forward. The new economics of software development The idx_58fa487a software industry has reinvented itself several times over the past fifty years, and each transition fundamentally changed its economics. In the mainframe era, software was tightly coupled to hardware and delivered by small groups of highly specialized engineers. The personal computer revolution shifted software into packaged products, creating scale through distribution. The internet era then transformed software into continuously connected services, and the rise of cloud computing and software as a service (SaaS) changed the economic model again: infrastructure became elastic, deployment became continuous, and software evolved from a one-time purchase into a recurring subscription business. Agile and DevOps accelerated delivery cycles further, reducing the cost of release and turning engineering velocity into a competitive advantage. • • • • • • A mainframeidx_207cc370 is a large, centralized computer system designed to process massive volumes of transactions and data for enterprises and governments. Dominant from the 1960s onward, mainframes powered critical business operations such as banking, airline reservations, insurance, and payroll systems, with software tightly coupled to proprietary hardware and operated by highly specialized engineering teams.

Today, agentic developmentidx_80d9ea09 represents another structural shift, but this time the disruption is not only in how software is delivered, but in how it is produced. AI agents are beginning to perform meaningful portions of the software lifecycle, although with varying degrees of maturity: coding, testing, and documentation are increasingly reliable, while more complex activities such as research, specification drafting, architecture generation, security validation, release orchestration, and operations remain less mature and more dependent on human oversight. The economics therefore change from scaling primarily through headcount to scaling through reusable agent artifacts (e.g., prompts, skills and more, which will be introduced in the upcoming chapters), orchestration systems, and autonomous execution loops. Small teams equipped with strong agentic workflows can now operate at a throughput that previously required entire departments. Needless to say, the cost of generating software is falling, and available evidence increasingly confirms the productivity gains. In a controlled study of 95 professional developers, those using GitHub Copilot completed a JavaScript coding task 55% faster than those working without it. In a separate enterprise study with Accenture, Copilot adoption was associated with an 8% increase in pull requests, a 15% increase in pull-request merge rates, and an 84% increase in successful builds. Yet the work has not idx_a271e7ec isappeared; it has moved. Faros AI's analysis of telemetry from 10,000 developers across 1,255 teams found that teams with high AI adoption completed 21% more tasks and merged 98% more pull requests (PRs), while pull-request review time increased by 91%. A related Faros analysis found that developers on high-adoption teams interacted with 47% more pull requests per day. CodeRabbit's review of 470 open-source pull requests found that AI-authored changes contained an average of 10.83 issues per pull request, compared with 6.45 for human-only changes, approximately 1.7 times as many. Meanwhile, Aikido Security's 2026 survey of 450 security and development practitioners found that 69% of organizations had identified vulnerabilities introduced by AI-generated code, while one in five had experienced a serious security incident linked to it. Figure 1.1 summarizes this tension between faster software generation and the growing burden placed on review, quality, and security. 3 The Impact of AI: From Vibe Coding to "Steered" Agentic Development
