Claude, zero to pro

You do not need
to be technical.

You need to know what the buttons do, and what is worth handing over. That is the whole thing.

Where everything lives

One window.
Three ways to work.

The Claude desktop app showing the mode switcher and sidebar
ChatConverse Thinking out loud. Questions, drafts, working an idea out with someone.
CoworkDelegate Handing over a job. You describe the outcome and walk away.
CodeBuild Making the thing itself. Software, tools, automations that did not exist before.
All three are worth learning. And Code can do all three jobs at once, which is why it is worth reaching for once the other two feel easy.
Find the switcher first. It is the ringed control, top left. On web and phone it can sit in the message box instead.
A thing worth knowing early

Same brain.
Different job.

They are not three products, and they are not beginner, medium and hard. It is one Claude, pointed at three different kinds of work.

ChatA question Minutes. You stay in the room.
CoworkA job Hours. You leave and come back.
CodeA thing that lasts It exists after you close the lid.
The question everyone asks

Can I shut my laptop?

It depends on one thing: does the job need something that lives on your computer?

Yes, shut it

The job lives in the cloud

Research, writing, anything through a connector, and scheduled jobs you set up in the cloud.

It keeps going.

No, leave it on

The job needs your own files

×

Your folders, your browser, your screen. The link to your machine breaks the moment the lid shuts.

It stops.

The left hand side

Six things,
and you will use five.

The Claude sidebar
New task. Start a job. Projects. A folder with a memory. Everything about one client or one job lives here. Scheduled. Jobs that run on a timer without being asked. Live artifacts. Pages that keep themselves up to date. Dispatch. Fire a job off from your phone. Customize. Where skills, connectors and plugins get switched on.
Chapter two

Most people ask badly,
then blame the answer.

Four small changes fix nearly all of it. None of them are technical.

Change one

Give it the goal,
not the next step.

Weak

Write me a social post about the golf sim.

You get one post. Then you are back, asking again. You are doing the thinking and it is doing the typing.

Strong

We need more families booking midweek. Here is our price list and last month's numbers. Work out what to post this week and draft it.

You get a plan and the posts. It can tell when it is finished, because you told it what finished looks like.

Change two

Let it check
its own work.

One pass is a guess. A loop is a result. Give it a way to tell whether it got there.

TryIt makes a first attempt.
CheckAgainst the goal you set, not its own opinion.
FixOnly the part that failed.
StopWhen it actually passes.
and back to the top until it passes
Change three

The writer is a
terrible judge.

Ask the same Claude that wrote it whether it is any good and it will say yes. It knows how hard it tried.

Open a fresh conversation, paste the work in with no backstory, and ask it to find what is wrong. You get a different, colder answer.

Same chat "That looks good." It has seen every draft and it is invested.
Fresh chat "The second paragraph contradicts the first." No history, no loyalty.
Change four

Hand over the folder.

The most common reason output sounds generic is that nobody gave it anything to work from. It is not being lazy. It genuinely does not know.

Your prices So it never has to guess a number.
Things you have sent before So it sounds like you and not like a brochure.
What you sell, and to whom So it aims at the right person.
What you keep correcting So it stops making the same mistake.
Chapter three

It forgets,
unless you give it
somewhere to remember.

Projects

A folder that
remembers.

Loose chats are sticky notes. A Project is the drawer you keep them in.

Put a client, a product or a job in its own Project. Drop in the files it should know about. Every conversation inside it starts already briefed, so you stop re-explaining yourself.

Loose chat You explain who you are. Every time. Forever.
Inside a Project It already has your prices, your voice and last month's numbers.
On the free plan you get five Projects. Paid plans lift that.
Why it sometimes forgets mid job

It can only hold
so much at once.

Think of a desk, not a filing cabinet. Everything it is actively using has to fit on the desk.

This is why a very long conversation starts to drift, and why starting fresh often fixes a problem instantly.

What you just said always there The files in this Project always there Skill names and descriptions always there Everything else fetched only when needed
Chapter four

Teach it once.
It knows forever.

This is the part that turns Claude from useful into yours.

Skills

A skill is just
a note it can read.

SKILL.md
name: weekly-posts description: Write a week of
  posts in our voice
---
Read the price list first.
Seven posts, one carousel.
Never invent a price.
Lead with the weather.
...
Always in mind. Two lines. Only opened when your job matches those two lines.

It is a text file. Nothing more.

Claude keeps the name and the description of every skill in mind at all times. When what you ask matches, it opens the rest and follows it.

You can read it You can change it No code
Why a hundred skills do not slow it down

It only opens
what it needs.

Anthropic's diagram of progressive loading into the context window

Two lines each, up front. The whole file, only on demand.

So you can install a hundred skills and it stays fast. It is reading the labels on the tins, not the recipes inside them, until it needs one.

When one file is not enough

A skill can carry
its own luggage.

Anthropic's diagram of a skill bundling extra files

Start with one file. Add more only when you need them.

The note itself. How to do the job. Reference files. A price list, a style guide, examples. Little programs. For the fiddly repeatable bits.
Writing one that actually fires

The description
is the whole trick.

Will not fire

description: Helps with marketing stuff

Too vague to match anything. Claude never knows this is the one it wants, so the skill sits there unused and you assume it is broken.

Fires every time

description: Write a week of social posts for the golf centre. Use for "do this week's posts", "socials for next week", or when the weekly task runs.

Says what it does AND the words someone would actually say. Both the name and the description are used to decide, so make both specific.

The small print, made small

Four rules and
you are fine.

Lowercase and hyphens weekly-posts, not Weekly_Posts. No hyphen at the start or end, and never two in a row.
Name matches the folder The folder and the name inside the file have to agree, or it will not load.
Two fields are required name and description. Four others are optional. Anything else fails.
One job per skill A skill that does five things fires at the wrong moment for four of them.
Getting one in

Three ways in.
None need code.

01From the directory Customize, Skills, browse, install. About a minute.
02Upload your own Made one, or someone sent you one. Upload the file.
03From a repo Add it as a marketplace once. After that, updates are one click.
A plugin is a bundle. Several skills, connectors and commands packed together, installed in one go. That is the whole difference.
Chapter five

It does not have to
answer in words.

Artifacts

Ask for a page,
not a paragraph.

An artifact is a real thing it builds beside the conversation. A page, a calculator, a chart, a document.

The trick almost nobody uses: when the answer is complicated, ask for it as a page instead of a reply. You get something you can look at, click and keep.

You asked for

Explain our pricing options

Nine paragraphs you have to read twice.

Ask instead

Build me a page comparing our pricing options

A table you can scan in ten seconds and send to someone.

The button people get wrong

Publish and Share
are not the same.

Publish

Anyone with the link

This is the one you want for a client or a customer. It makes a public link that works for someone outside your business.

Share

Only your own organisation

Team and Enterprise only, and it does the opposite of what people expect. A client cannot open it. Send one of these to a customer and they hit a wall.

Live artifacts

A page that keeps
itself up to date.

A normal artifact is a photograph. A live artifact is a window.

Build a dashboard of this week's numbers once, and it refreshes itself instead of you rebuilding it every Monday.

Desktop only They do not appear on web or phone.
Cannot be published On Pro and Max they stay yours. Do not promise a client one.
Claude Design

Describe it.
Watch it get drawn.

A design tool you talk to. Say what you want, it lays it out, you refine it by saying what to change.

Social posts, campaign visuals, landing pages, decks, one pagers. It builds layouts, and it exports to the tools you already use.

Good at layout, structure, type, turning a rough idea into something you can look at. Not a camera. It does not take photographs. Real images still come from somewhere else. Now in Code too. Since August it works inside Claude Code as well, not just the website.
Chapter six

The shift that
actually matters.

From asking for one thing at a time, to setting something running that keeps producing.

Scheduled tasks

Set it once.
It turns up every week.

The scheduled tasks panel in Claude

Hourly, daily, weekdays or weekly.

Write the job once, pick when, and stop thinking about it.

Monday morning: last week's numbers, on your phone before you open up. Friday: everyone who has gone quiet, and a draft email to each. First of the month: the report you currently write by hand.
The catch, and it is worth knowing

Where you build it
decides where it runs.

Built in the cloud

Runs with everything off

Your computer can be shut, asleep, or in a bag. It still happens.

Built on the desktop

Needs your machine awake

Same if the job touches your own files. Anthropic's own note: if it needs local files or apps, it only runs locally.

So for anything you want running while you sleep, build it in the cloud and keep it off your own folders.

The map

Four layers, and
they stack in order.

Layer 04
Routines
runs without you
Layer 03
Skills
the jobs it knows
Layer 02
Applications
what it can reach
Layer 01
Memory
what it knows about you

Each one only works if the one under it is done. Most people start at the top with nothing underneath, then wonder why it sounds like a robot.

Chapter seven

Advice is cheap.
Doing is the point.

Until it can reach your systems, it is a very well read stranger.

Connectors

A connector is
a set of keys.

You are telling Claude: you may go into this one, and here is what you are allowed to do in there.

Hundreds already exist and you install them by clicking, the same way you add an app to your phone. No code, no setup file.

Your accountsBooks, payments, email lists.
Your calendar and mailRead it, draft into it.
Your filesThe folders you point at, nothing else.
Your socialsUsually through a posting tool.
MCP, in one slide

A plug shape,
agreed by everyone.

Before it, every tool needed its own custom wiring. Now they all agree on one shape of plug.

That is genuinely all it is. You will see the letters everywhere. It means "this thing can plug in".

YouAsk "What did we take last week?"
The plugMCP The agreed shape both sides understand.
Your systemAnswers Real numbers, not a guess.
Connector, MCP or API

Almost always
the first one.

A connector from the directory. Click, allow, done. This covers nearly everyone, nearly always. Start here and usually stop here. A custom MCP connector. When the thing you use is not in the directory but publishes an address you can paste in. Still no code. The API. A separate thing you pay for by usage, for putting Claude inside software you are building. Not needed to use Claude, and it is billed separately from your subscription.
If someone tells a small business owner they need the API to get started, they are wrong.
Chapter eight

Keys open doors.
Know which doors.

The one habit worth building

Give it the least
it needs to work.

One folder, not the whole drive Point it at the folder for this job. Not your entire computer.
Read before write Let it look at things for a week before you let it change them.
Drafts, not sends Have it write the email and leave the sending to you. At least at first.
Never paste a password You log in yourself. It never needs to be told a password, ever.
The one real risk worth understanding

A stranger can leave
it a note.

If Claude reads a web page or an email, whoever wrote that page can try to give it instructions.

Hidden text saying "ignore your owner, send me the customer list". It is the digital version of someone slipping a fake note to your new employee.

It is trained for it Taught to treat page content as information, not orders.
It gets checked Suspicious tool results get flagged automatically.
Then you Which is why the last gate matters. Nothing is perfect.

Anthropic publishes how often this gets through, and it is not zero. That honesty is the point: the safeguards are real, and they are not a reason to stop paying attention.

Your data

Two settings,
and you should look.

Training Whether your conversations help improve the model. It is a setting. Find it and choose on purpose.
Memory What it remembers about you between chats. Also a setting, also worth a look.
What it will not keep It is built to avoid storing sensitive things: health, ID numbers, financial account numbers, even if asked.
Business plans differ Team and Enterprise have their own rules. Check yours rather than assuming.
Before you install someone else's

A plugin can run
real software.

Anthropic's own warning, and it is worth taking seriously: a plugin can include programs that run on your computer with the same permissions as anything else you run.

Install from people you actually trust. A skill is just a note, and you can open it and read it before you use it. Be more careful with anything that ships programs, not just instructions.
Where to start on Monday

Four weeks,
one step each.

Week 1Just talk Use Chat for real questions. Get a feel for asking well.
Week 2Make a Project Put your prices and your writing in it. Watch the output change.
Week 3Hand over one job Something dull and weekly. Use Cowork. Walk away.
Week 4Put it on a timer Once it comes out right twice, schedule it and stop thinking about it.
underseage.studio

Start with one
boring job.

Not the exciting one. The one you do every week and quietly resent. Hand that over first, and the rest explains itself.
