Step 5: Preview the advanced surface with custom skills, browser use, and nodes

The seven-day path saves the more ambitious surface for later, but you can still preview it in one step if you keep the goal small: understand what each advanced feature is for and try one minimal version.

Custom skills are intentionally simpler than they sound

Day 7 explains custom skills in a very beginner-friendly way: the minimum version is just a SKILL.md file that tells the assistant what it can do, how to do it, and what to return.

• One skill should do one job.
• The file should spell out the output format.
• Sensitive actions should carry a confirmation rule.
• You do not need a full SDK mindset to try the first one.

Browser access is the moment the assistant starts seeing the web directly

Day 4 introduces browser access as the way to inspect pages that search alone cannot cover. Day 7 keeps the message practical: browser control matters when the assistant needs to inspect, click, screenshot, or read a page like a real user.

Nodes are the device layer

Day 7 describes nodes as lightweight clients that let the assistant reach other devices. That means the assistant can stop living only on one server and start seeing phones, desktops, or device-specific surfaces.

• A phone node can capture photos, location, and notifications.
• A desktop node can screenshot, record, and help with browser control.
• A home setup can use nodes to bridge into device control.

What to keep small in this first preview

• Write one tiny custom skill instead of designing a whole library.
• Try browser viewing before browser-heavy automation.
• Treat nodes as a preview of what devices can expose, not a reason to wire everything at once.

A good outcome for this step

By the end of this step, you should know which advanced branch feels most exciting for your own use: skill building, browser work, or device reach. That is enough for a first preview.
