What You Will Learn in Builder Methods

✅ How to install, configure, and operate Claude Code as a terminal-based AI coding agent — including launching it for the first time, setting up the .claude folder, and writing a claude.md file that gives the agent context about your project.

✅ The Spec-Driven Development methodology: how to write structured specifications that tell AI agents what to build and how to build it, so outputs are consistent and aligned with your codebase standards rather than generically correct.

✅ How to use Agent OS to extract your existing codebase patterns into documented standards and inject those standards into your agent's context when working on new features — making Claude Code build your way, not its way.

✅ How to work with Claude Code's Plan Mode to shape specs before implementation, and how to use Task Lists so the agent tracks complex multi-step work without losing context.

✅ How to run multiple AI agents in parallel using Git Worktrees and Cursor — assigning different agents to different branches and comparing their work.

✅ How to set up Claude Code Subagents and Custom Skills — creating specialized agents with defined roles and reusable slash commands that execute inside your workflow.

✅ How to use Claude GitHub Actions to run Claude Code as a cloud coding agent, enabling automated PR reviews and background tasks without running the agent locally.

✅ How Design OS structures the planning phase — from product idea through UI wireframes and component specs — so that when you hand the spec to a coding agent, the agent has enough context to produce production-ready implementations.

✅ How to keep documentation current using an AI-assisted documentation workflow — ensuring your agent always has accurate project knowledge rather than stale context.

✅ How real products get built with AI from scratch — including decision points, debugging sessions, design iterations, and the moments where the builder overrides the agent — through unedited project ride-alongs.

Who Should Take Builder Methods?

• Product developers building SaaS or internal tools — You understand what you want to ship but spend too much time on implementation details instead of product decisions. Builder Methods teaches you to direct Claude Code with structured specs so the agent handles implementation while you focus on what the product needs to do.

• Career software developers ready to shift to AI-first workflows — You've been writing code professionally for years and want to work alongside AI agents effectively, not just use autocomplete. The Claude Code course and Agent OS workflow give you a system that integrates with how senior developers already think about codebase standards and specs.

• Non-technical or semi-technical founders who want to build their own product — You've tried vibe coding with AI tools but get inconsistent results because you're prompting without structure. Spec-Driven Development gives you a repeatable process for communicating requirements to an AI agent that produces usable code.

• Team leads who want their engineering team on consistent AI workflows — Instead of each developer figuring out AI tooling individually, Builder Methods gives teams a shared vocabulary (spec, Agent OS, Design OS) and documented workflows that can be standardized across seats.

• Developers who have tried Claude Code or Cursor but keep running into chaos — You started building with AI agents but the context window fills up, the agent goes in wrong directions, or you end up with inconsistent code. The training directly addresses these failure modes through structured methodologies.

About Brian Casel

Brian Casel taught himself web design after studying audio engineering, left a New York agency job in 2008, and has since bootstrapped and sold multiple software businesses without outside investment. In 2011 he launched Restaurant Engine, a website-as-a-service for the restaurant industry, which he sold in 2015. That same year he founded Audience Ops, a productized blog content service for SaaS and B2B companies, which he sold in 2021. He then built ProcessKit, a project management tool for recurring services, followed by ZipMessage — an async video conversation tool later rebranded as Clarityflow, a client communication platform he continues to run.

Builder Methods is his current focus: training professional developers and technical founders to build software using AI-powered workflows. Brian uses Claude Code as his daily driver and built Agent OS and Design OS — both open-source tools — to formalize the standards-and-spec approach he teaches. His content is explicitly independent of any commercial AI tool vendor.

What Problems Does Builder Methods Solve?

“I've been using Claude or Cursor but I keep getting inconsistent results — sometimes it works, sometimes it goes completely off course” — Builder Methods addresses this directly through Spec-Driven Development and Agent OS. The root cause of inconsistent AI output is usually under-specified prompts and no documented codebase standards. The methodology in this program teaches you to write structured specs before any implementation starts and to encode your coding standards into Agent OS so the agent builds consistently with your existing patterns.

“I don't know how to actually use Claude Code — there's no real beginner-to-advanced guide for it” — The Build with Claude Code course is exactly that. It starts at launching Claude Code for the first time and walks through every meaningful feature: Plan Mode, Task Lists, the context window, YOLO mode, Subagents, Custom Skills, Agent Teams, Git Worktrees, and GitHub Actions — in the order a builder would actually encounter them.

“My AI agent keeps going off on its own and making changes I didn't ask for” — The Clarifying Questions lesson (covering Claude Code's AskUserQuestion tool) and the Plan Mode lesson directly address this. These features, covered in dedicated lessons, let you configure the agent to ask before acting rather than assuming.

“I want to build a SaaS product but I'm not a full-time developer — I need AI to do more of the work” — The project ride-alongs in Builder Methods show a real product (Brian's own video library platform) being built feature by feature: invoice PDF generation, member profiles, a video series feature, and a marketing site template. Non-technical and semi-technical builders can follow the full process — design, spec, implementation — and see exactly where the builder directs the agent and where the agent operates on its own.

“I tried to get my team using AI tools but everyone is doing it differently” — Builder Methods Pro includes a team seat option specifically for this situation. Agent OS provides a shared system for documenting codebase standards, and Design OS gives teams a common design-to-spec handoff process, so teams have consistent workflows rather than individual approaches.

“I know vibe coding but I want to learn how professional builders actually work with AI” — Builder Methods is explicit that it targets people ready to go beyond vibe coding. The program's entire architecture — Spec-Driven Development, Agent OS, structured specs — represents how professional builders use AI agents with discipline, not just fast prompting.

What Makes Builder Methods Different

• Spec-Driven Development as a first-class methodology — Most AI coding content focuses on which tool to use or what prompt to write. Builder Methods centers on writing specs before prompting — a structured planning layer that makes AI agent outputs predictable. This is not a tip; it is the entire methodology the course is built around.

• Agent OS and Design OS are open-source tools you can use immediately — Unlike courses that teach general principles, Builder Methods comes with two functional open-source tools (Agent OS on GitHub under buildermethods/agent-os and Design OS under buildermethods/design-os) that implement the workflows taught in the course. Learners aren't just watching theory — they're deploying actual systems.

• Real product build sessions, not demo apps — The project ride-alongs in Builder Methods are sessions from Brian building actual features of his real video library platform: a PDF invoice generator, member profiles, a video series system, and a marketing site template. These show the real friction, decisions, and debugging that happen in production AI development, not a clean demo-ware walkthrough.

• Tool-independent training — The sales page explicitly states the training is not owned by any AI tool vendor and is designed to be applicable across Claude Code, Cursor, and other AI tools. The methodology — particularly Spec-Driven Development — works with any agentic coding environment.
