Founder OS — Where Does Each Tool Fit

Day 4 of 30  ·  Claude Code Challenge

where does each tool fit

a framework for knowing which one to open before you start. not just for technical people.

what each one actually does

same Anthropic product family. four completely different modes of work.

Claude Code is not "no-code"

It's a completely different level of control. You get skills, hooks, and scripts you can actually run. You build a knowledge system Claude reads every session (CLAUDE.md). You open it from Cursor, from your terminal, from anywhere. You spin multiple agents in parallel. You have root-level control over what it does and how it does it. Cowork can't do that, and that's fine. That's the point. If Cowork is working for you, stick with it until you need more power.

the natural progression

you don't have to use all of them. but if you want to scale, this is how it goes.

01
Claude.ai
Quick questions, drafts, research. No setup. Start here. Everyone on your team can use it tomorrow.
02
Cowork
When you need an agent that actually takes actions. Accesses files, controls browser, executes tasks. Everything in this series works here too.
03
Claude Code
When you need more power than Cowork. Skills, hooks, scripts, agents, full terminal control. Move here when you feel the ceiling.
04
n8n
When Claude Code hands off a clean workflow. It runs 24/7 in the background. Clients can see it, debug it, own it.

generate diagrams from Claude Code

the diagram below was generated using the Excalidraw skill for Claude Code. Describe what you want, get a clean visual back.

get the Excalidraw skill

You can find the Excalidraw skill (and other useful skills) at github.com/walidboulanouar/ay-skills. Install it, describe any diagram in plain english, and Claude Code generates the visual for you. No Figma. No drag-and-drop. Just words to diagrams.

Claude Code → n8n skill + MCP

next up: the skill and MCP that lets you deploy automations and agentic workflows directly into n8n, without touching the UI.

deploy to n8n from Claude Code
describe the workflow in plain english → Claude Code plans it → builds it node by node → validates each step → deploys directly into your n8n account. no manual JSON import. no copy-paste. one command.
skill + MCP → coming soon
