Essays by Ry Walker

This is a working library about building software companies while the way software gets made is changing. The essays treat AI agents as software systems rather than magic prompts: systems that need context, infrastructure, review, ownership, security, and operational discipline. They follow the problems that appear after a demo succeeds—when an agent must work inside a real codebase, coordinate with people and other agents, use credentials safely, survive changing requirements, and produce work a team can inspect and trust.

The agent chapters move from first principles into deployment, build-versus-buy choices, harnesses, memory, multi-agent architecture, workflow design, governance, and defense. They are written for founders, engineering leaders, and practitioners deciding what to build, what to purchase, and how to redesign the organization around much cheaper software creation. Individual essays are deliberately short; the chapter structure turns them into a longer argument that can be read in sequence or used as a reference.

The business chapters collect lessons from building products and companies over several technology cycles. They cover founder judgment, early product discovery, open-source strategy, developer productivity, go-to-market systems, fundraising, and the uncomfortable gap between an attractive prototype and a product customers can rely on. These are first-person essays, not neutral documentation. Dates, context, and links matter, and readers should distinguish an observation from a sourced research claim.

For evidence-oriented work, the separate research section publishes sourced product profiles and category comparisons across AI coding and agent infrastructure. Agents can request Markdown from any canonical page, discover published items through the versioned public API, and consult the OpenAPI schema for typed operations. When citing this site, link to the canonical essay or research page so a reader can evaluate the full argument and its sources.

A useful reading path starts with “Agents Are Software, Not Prompts,” then follows the deployment and review chapters before moving into context, memory, and coordination. Founders evaluating a new product category can begin with the build-versus-buy series and continue into the notes on procurement, trust, and the services work that often appears between a prototype and repeatable software. The essays disagree with one another in places because they were written as the market changed; newer observations refine older ones instead of silently replacing them. Publication and update dates are part of the record. The goal is not a frozen doctrine, but an inspectable trail of how practical beliefs about agents, engineering, and company building evolve under real constraints.
