Claude Hub
Every Claude workflow I've tested and published: Code workflows, Cowork setups, Skills tutorials, CLAUDE.md files. Real prompts, real failures, nothing theoretical.
Last updated: May 2026
TL;DR: Twelve tested guides on Claude covering Cowork, Code, Design, Skills, Opus 4.7, and CLAUDE.md. Every prompt is real and every failure is documented. Updated April 2026. Start with Cowork for autonomous workflows, Code for terminal control, and Design for UI from prompts.
I started writing about Claude in September 2025. Back then, Cowork didn’t exist, Skills weren’t a thing, and Code was a niche CLI tool that maybe a few hundred developers used daily.
Many posts and tens of thousands of words later, this page exists to help you decide where to start.
This is everything I’ve published about Claude on Product with Attitude, organized so you can find what you need and skip what you don’t.
Every guide is tested. Every prompt is real. Every failure is documented. Nothing theoretical.
Claude is the #1 AI app on Apple’s U.S. App Store right now, which means a lot of people are about to need these guides.

Claude Cowork vs Chat vs Design vs Code
Which One Do You Need?
Chat is a conversation. Cowork is a workflow engine. Design is a design partner. Code is a development partner.
That’s the simplest way we can frame the three modes for anyone deciding where to start.
Claude is Anthropic’s AI assistant.
Chat, Cowork, Design and Code are four different ways to use it. Choosing the right mode depends on what you’re trying to accomplish.
Chat is for questions. Chat handles conversations, artifacts, and quick answers. No file access, no sub-agents, no plugins. It’s the baseline Claude experience.
Cowork is for workflows. Cowork handles autonomous knowledge work: it plans tasks, spawns parallel sub-agents, reads and writes real files in a sandboxed environment. This is where Claude becomes a working partner, not just a chatbot.
Design is for interfaces.
Design turns prompts into editable UI. It generates layouts, components, and design systems, and produces a machine-readable spec that can be handed off to code. It’s built for shaping ideas into visual structure.Code is for code. Claude Code is Anthropic’s CLI tool that offers the same agentic power as Cowork with direct filesystem access and project-scoped configuration. It runs in the terminal, reads your codebase, and executes multi-step development tasks.

Why Claude Design Only Works Because of Opus 4.7
In this article, I explain why Claude Design works in the first place, and why that comes down to Claude Opus 4.7, whose jump in vision accuracy and self-checking behavior makes reliable UI interpretation possible.
Claude Cowork
Cowork handles autonomous knowledge work: it plans tasks, spawns parallel sub-agents, reads and writes real files in a sandboxed environment.

Claude in Builder Stories
The Time Claude Said “Don’t” and the Builder Ignored It
A real case study in trusting your product judgment over AI advice. I documented every moment Claude suggested removing features, and Karen Spinner overruled it. Nobody else publishes these stories because they make the AI look fallible. That’s why I did.

What Makes This Library Different
Who is this for?
Anyone who uses Claude for real work: writers, PMs, builders, creators, knowledge workers. Whether you picked up Claude yesterday or you’ve been using it since Sonnet 3.5, you'll find a workflow you haven't tried.
How is this different from Anthropic’s documentation?
Anthropic explains what Claude can do. I show what works: the prompts, the failures, the workarounds they left out. I broke three workflows following the official docs before figuring out what was missing. That’s why these guides exist.
How often is this page updated?
Every time I publish a new Claude-related guide, it gets added here. The “Last updated” date at the top reflects the most recent addition. As of March 2026, this library covers 12 original guides across Cowork, Code, Skills, and CLAUDE.md configuration.
This library started with one Cowork post in January 2026 and grew into one of the most comprehensive independent Claude resources on Substack. Every guide is written from the perspective of someone who builds with Claude daily, not someone who read the changelog.
