Match the work you do most to the right vertical track
After this, you'll be able to match your main use case to the right vertical track, and know what each track assumes you already learned in Fundamentals.
Before you start
Complete Building a personal Claude operating system first; this lesson builds on that finished setup, because once Claude is your default tool for recurring work, the next question is which vertical track deepens the work you do most.
The idea
Fundamentals is the horizontal foundation; every other track goes vertical on one kind of work. It taught you the platform: what Claude is, how it remembers, what it produces, how it connects, and where the surfaces fit.

A vertical track does not re-teach that. It goes deep on one kind of work and assumes you already have the platform basics. So picking your next track is not about which sounds most advanced; it is about which matches the work you do most.
Here is the before and after: Without the map, you finish Fundamentals and either stop or pick the track that sounds most impressive and bounce off it. With the map, you name your most common task, go straight to the track built for it, and spend your next hour learning, not guessing.
Now try it write down the one kind of work you do with Claude most, then match it: Writing for drafting, Research for synthesis, Operations for workflows, Excel for spreadsheets, Portfolio for a no-code website, Cowork for hands-off Desktop automation.
Pick the track that matches your real work, not the one that sounds most advanced.

Paste this into Claude
I just finished the Claude Fundamentals track and I want to pick the right next track instead of guessing. Here are the vertical tracks available: - WRITING: drafting, editing, and shaping written work - RESEARCH: finding, reading, and synthesizing information from many sources - OPERATIONS: repeatable business workflows and process automation - EXCEL: spreadsheets, formulas, and data analysis with Claude - PORTFOLIO: building a live portfolio website for your work, no code required - COWORK: depth on Desktop Cowork, scheduled tasks, and Computer Use - GOOGLE ANTIGRAVITY: the Google agentic ecosystem, from Workspace automations to Antigravity agents Here is the work I actually do most with Claude: [describe, in 2-3 sentences, the kind of tasks you reach for Claude for most often] Please: 1. Recommend the single best next track for me, and explain in one sentence why it fits my work 2. Name my second-best option in case my needs shift 3. For my top recommendation, tell me which Fundamentals concepts it assumes I already know, so I can confirm I'm ready 4. Tell me honestly if any track would be a poor fit for me right now, and why

AI can help with this
Paste this: 'I finished Claude Fundamentals. The tracks are Writing, Research, Operations, Excel, Portfolio, Cowork, and Google Antigravity. Here is the work I do most: [2-3 sentences]. Recommend my single best next track with one reason, name a second choice, list the Fundamentals it assumes, and flag any track that would be a poor fit for me now.'

You can complete the lesson outcome in a real Claude chat, Project, Artifact, Connector, Desktop, or Code surface.
Key takeaways
Fundamentals is the horizontal base; every other track goes vertical on one kind of work and assumes the platform basics. Pick the track that matches your most common task, not the one that sounds most advanced.
