Colleen Schnettler is a Ruby on Rails developer who worked at ClickFunnels, runs SimpleFileUpload, and is now launching a technical marketing consulting business. She's one of those builders who tried every AI tool on the market—and when they all fell short, decided to just build her own.
Agent OS v3 is here — rebuilt from the ground up for how we actually build in 2026. I stripped out 70% of the framework. What's left: a leaner system for discovering, documenting, and injecting your coding standards into AI-powered, spec-driven development.
Claude Code in 2026 is not what it was when it launched. After a year of building frameworks, custom setups, and elaborate systems to make AI coding work, we've come to a point now where... most of that is overkill.
I spent a week building a complex n8n workflow for AI image generation — then scrapped it and rebuilt the whole thing as a Claude Code skill in 30 minutes. Here's why automation without intelligence doesn't work, and how Claude Code Skills became my secret weapon for repeatable brand visuals.
Brian walks through creating a reusable static HTML template for one-page marketing sites, then uses it to build and deploy a real marketing site for his new tool, Inbox Summaries. The video covers everything from structuring the template with Tailwind CSS and vanilla JavaScript to writing marketing copy with Claude and deploying to Cloudflare Pages.
Cursor's new visual editor lets you tweak CSS visually and apply changes directly to code. I break down when it's actually useful and when you'll want to reach for something else.
A workflow for maintaining accurate product documentation by keeping draft docs in your codebase and having your AI agent update them after each feature change—while the context is still fresh.
I was genuinely excited about Google Antigravity's fresh ideas for the agentic IDE—multi-project management, multi-agent orchestration, and that clever screen recording review process. But when I actually tried to build with it... Well, you'll see...
The Builder Method is the process-oriented framework that guides everything in Builder Methods Pro—from design through build to refinement. This video establishes the mental model for working productively with AI while keeping your creativity and craft at the center.
Here's a great way to tackle your backlog of GitHub issues by simply mentioning Claude in your GitHub comments. Watch me do this on the builder methods site using the Claude GitHub actions integration.
Let's compare Claude Opus 4.5 and Google Gemini 3 to see how they stack up when it comes to planning, designing frontend and backend for a new app! Plus how I evaluate new frontier models when they drop...
Cursor 2.0 dropped last week, and unlike most recent AI updates, it's actually changed how I work. Two features in particular: Cursor's new Composer model that's 10-50x faster than any other coding model, and parallel agents that finally make running multiple autonomous builds practical. I'll show you Composer building and...
Cloud-based coding agents from Claude Code on the Web, Cursor Cloud Agents, and Codex all promise the same thing: kick off a task, walk away, and come back to a completed pull request. But do they actually deliver? And more importantly, which one fits into your real-world development workflow?
Claude just launched Skills across all their platforms, and I've spent a week testing the Claude Code implementation specifically. Do Claude Code Skills actually solve problems developers have, or are they better suited for consumer platforms like Claude.ai? I compare Skills to the developer tools we already use...
I demonstrate my workflow for running multiple AI coding agents (Claude Sonnet 4.5 and Cursor's Composer 1) in parallel on the same feature, then comparing their work to choose the best implementation. The focus is on solving the practical challenges of reviewing agent work in git worktrees by using a branch-based approach that makes testing, debugging, and merging much more manageable.
In this video, I show how to build a fully automated PDF invoice system in Rails—from Stripe test data to downloadable invoices—using Cursor 2.0 and their new Composer model.
