The starter skills
worth installing first

By the end of this chapter you know which official skills are worth turning on before anything else, how to enable them safely, and why you do not go installing skills from strangers at this stage.

Watch: turning on a skill, and what it changes about how Claude works

The beginner course taught you what a Skill is: a folder of instructions that Claude loads only when the job comes up, so your standing rules do not clutter every conversation. This chapter is the next step. Before you build your own, there is a small set of official skills worth turning on, because they cover jobs you already do and they come already made and maintained by the people who make the tool.

The reason to start here rather than build immediately is simple. You learn what a good skill feels like by using a few well-made ones first. And the official set covers a lot of ordinary work straight out of the box. Turning them on is a five-minute job and it changes what Claude can quietly do for you from that point on.

Start with the skills made by the people who make the tool. Earn your way outward from there. Official first, yours next, strangers not yet. That order is not caution for its own sake. It is how you stay safe while your judgment catches up.
THE SET WORTH TURNING ON

These are the official skills worth enabling first. Each one takes over a recurring job you would otherwise do by hand, and each is made and kept current by Anthropic, so you are not trusting a stranger's code.

The document skills
Real spreadsheets, slide decks, documents, and PDFs, made and edited as actual files. The workhorses. You may already have used them without noticing.
The skill maker
The official skill for building skills. It interviews you and scaffolds a new one properly. You use it in the very next chapter, so turn it on now.
The connector builder
For building your own connection to an outside tool. You do not need it yet, but it is the official, safe way in when you reach the connect-and-automate part.
The design helpers
Front-end design and brand-guideline skills that make what Claude builds look considered instead of default. You lean on these hard in the anti-slop chapter.

You do not have to use all of them today. The point is to have the shelf stocked with vetted tools, so that when a job comes up, the right skill is already there and already trusted. Notice the pattern in the list: each one maps to a later chapter of this course. The skill maker feeds the next chapter, the connector builder feeds the automation part, the design helpers feed the anti-slop chapter. Turning them on now means the tools are ready when you arrive.

HOW TO ENABLE THEM SAFELY

Enabling a skill is done in the app, not the terminal. You do not need any technical setup for this chapter. The path is in your settings, under the section for capabilities, where you switch on the ability to run code and create files, and then toggle the individual skills you want. That is the whole operation.

Here is a prompt that gets Claude to walk you through the current path for your exact plan and platform, since menus move around and this course refuses to print steps that go stale.

Get the current enable steps
I am on [my Claude plan, e.g. Pro] using [the web app / desktop]. Walk me through, in the current interface, how to: 1. Turn on code execution and file creation. 2. Find the skills section in settings. 3. Enable these official skills: the document skills (spreadsheet, slides, documents, PDF), the skill-creating skill, and the front-end design and brand-guideline skills. Give me the steps for the interface as it is now, and tell me how to confirm each one is actually on.

WHY NOT SKILLS FROM STRANGERS, YET

You will quickly discover there is a whole ecosystem of skills people share, and some of them are genuinely good. This course does not send you there yet, and the reason is not snobbery. A skill can contain code that runs on your behalf, with your access. A well-made one from a source you trust is a gift. One from a stranger is you agreeing to run code you have not read, with your files and your permissions, on the promise of a description.

At this tier the rule is plain: official skills, and the ones you build yourself, which is the next chapter. The wider ecosystem is real and worth knowing exists. But you install from it the way you would run any stranger's program on your machine, which is carefully, having actually looked, and once you have the judgment to tell a safe one from a risky one. That judgment is what this whole part of the course is building.

NOW YOU TRY · APPLY
Stock your shelf

Open your settings and turn on code execution and file creation, then enable the official document skills, the skill-creating skill, and the design skills. Use the prompt above if the menu path is not obvious. Then prove one works: ask Claude to make a real spreadsheet or a short slide deck about something from your actual work, and download the file it produces.

Right if you ended with a real file Claude built using a skill you just enabled, and you know where in settings to turn skills on and off.
Show the worked solution
The drill is done when you are holding a file that did not exist before, made by a skill you just switched on. Say you enable the document skills and then ask for "a spreadsheet of my five recurring monthly costs with a column that totals them." A minute later there is an actual spreadsheet to download, with a working total, not a picture of one and not a code block for you to assemble. That small moment is the whole point of the chapter: the capability was sitting there dormant, and one toggle turned it on. Do the same with the design skills by asking for a simple one-page layout, and you feel the difference between Claude's plain default output and something that looks considered. You have now stocked the shelf with vetted, maintained tools, and just as important, you know exactly where the switches are, so you can turn a skill off as easily as on. That is the safe posture: everything on your shelf is there because you chose it and you trust its source, and nothing runs that you did not knowingly enable.
WATCH FOR
You skip the skills and keep doing the work by hand. The official document skills alone replace a lot of manual busywork. Turning them on is a five-minute win you keep forever.
You install an exciting skill from a stranger to try it. A skill can run code with your access. At this tier: official and self-built only. Vet the ecosystem later, with your eyes open.
You cannot get a skill to trigger. Usually code execution and file creation are still off, or the skill is not toggled on. Check both in settings before assuming it is broken.
You turn everything on and forget what is running. Enable what maps to work you actually do. A shelf you curated beats a shelf you dumped everything onto.
WHAT YOU LEARNED
The takeaways
  • Before building your own skills, turn on the official set: the document skills, the skill maker, the connector builder, and the design helpers.
  • Each starter skill maps to a later chapter, so enabling them now means the right tool is ready and trusted when you arrive at the job.
  • Enabling is an in-app settings job, no terminal: switch on code execution and file creation, then toggle the individual skills.
  • Skills from strangers can run code with your access. At this tier the rule is official and self-built only, and you earn your way outward as your judgment grows.
  • A curated shelf of vetted tools, each one you chose and trust, beats both doing everything by hand and installing everything you find.
Your project · stock the shelf

Turn on the official starter skills for your account now, and make one real file to prove a skill works. You have the vetted tools in place. Next chapter you stop being only a user of skills and build one of your own, end to end, the way you would want a recurring job done every time.

The fastest way to trust your own judgment about skills later is to spend time with well-made ones first. Start on the official shelf. Build your own next. Walk into the wider ecosystem only once you can tell a gift from a gamble.
