Foundations & Orientation

The power-user mindset, the four modes, and the four building blocks. Short, then straight into building.
0:00 to 0:20
Foundations
The four modes

How Claude actually works

Think

Chat

The thinking layer. Ask, explore, decide.

Build

Code

The build layer. Plain language into working software.

Run

Cowork

The run layer. Hand off multi-step work, get finished files.

Make

Design

The make layer. A rough idea into polished visuals.

Chat is where you think. The other three are where work actually gets done.
The AI Internship . Claude Certified DeveloperFoundations . 5
Foundations
The one heuristic for tonight

Build it in Code. Hand the busywork to Cowork. Make it look right in Design.

The one heuristic
You leave having built, run and designed one coherent thing.
The AI Internship . Claude Certified DeveloperFoundations . 6
Foundations
The four building blocks

Skills, plugins, hooks, MCPs

Teach

Skills

Reusable instructions Claude loads for a task. A trained specialist you summon.

When to reach for itYou repeat the same shaped task and want a consistent result.
Share

Plugins

Bundles that add commands, skills and connectors in one install.

When to reach for itYou want your whole team on the same setup.
Guardrail

Hooks

Small scripts that fire automatically on an event to enforce a rule.

When to reach for itYou want a guardrail that always runs.
Connect

MCPs

The standard that connects Claude to outside tools and data.

When to reach for itThe work needs Claude to act in a system outside the chat.
Skills teach how you work. Plugins share it. Hooks keep it safe. MCPs connect it to your stack.

Meet Brightbrew Monthly

Tonight's running example
A specialty coffee subscription. One bag, freshly roasted, to your door every month for $24.
  • Audience. Home coffee drinkers who want cafe quality without the daily trip.
  • The feeling. Never run out of great coffee, discover a new roast every month.
  • Palette. Cream, espresso brown, a caramel accent.
  • You. Swap in a real offer from your week. Same steps, your input.

Claude Design

The fastest visible win. No red errors, a polished result in minutes. You bring the intent and the taste; Claude brings speed and options.

The make layer

Design is a conversation

The mental model
The first output is a draft you argue with. The skill is not making a poster, it is knowing what to say next.

The core loop

Brief, generate, iterate

1

Brief

The offer, the audience, the one feeling, the format. Tight beats stuffed.

›
2

Generate

Take the first render as a starting point, never the finish.

›
3

Iterate

Change the tone, tighten the copy, swap the emphasis. One move at a time.

Brightbrew example

The launch one-pager

Copy this prompt
Create a one-page launch graphic for Brightbrew Monthly, a $24 per month specialty coffee subscription delivered to your door. Audience is home coffee drinkers who want cafe-quality coffee without the daily trip. The feeling: never run out of great coffee, discover a new roast every month. Include a headline, a one-line value proposition, three short benefits, and a clear "Start your subscription" call to action. Keep it clean and warm, lots of white space, cream and deep brown palette.
What it producesA single graphic with a headline, subhead, three benefits and a CTA, in a warm palette.

Iteration prompts

Iterate with short prompts

Make the headline punchier, six words or fewer.
This feels too corporate. Warm it up so it feels like a cozy morning.
Give me a version sized for an Instagram square post.
Swap the palette to cream #F5EFE6 and espresso brown #3B2A20, keep everything else.
Try the "too corporate to cozy" shift — one short change at a time is the loop.

Best practice

The craft, and the pitfall

Do
Give a tight, clear brief
One feeling and a clean structure out-perform ten stacked instructions.
Treat the first output as a draft
The value is in the next instruction, not the first render.
Feed a vibe and two colours
A little brand direction stops it looking like a template.
Do not
Over-brief it into mush
Ten requirements average out into something bland.
Accept a corporate first pass
Name the feeling and it shifts fast.
Describe in pure abstraction
No colours or reference means a generic, off-brand result.
The AI Internship . Claude Certified DeveloperClaude Design . 16
Claude Design . You do
Your turn

Build your one-pager

1
Describe your offer in two or three sentences, the real one from your week.
2
Ask for a launch one-pager: headline, value prop, three benefits, a call to action.
3
Then reformat the same message as a vertical story graphic.
Win conditionOne one-pager plus one reformat. Keep both so you can compare.

Claude Code

Plain language in, working software out. You will build a page, fix an error, and clean a spreadsheet — each in a few minutes.

Claude Code
The build layer

You are the director, not the coder

The mental model
Plain language in, working software out. You describe what you want, Claude writes and runs the code.
The AI Internship . Claude Certified DeveloperClaude Code . 20
Claude Code
The on-ramp

A quick orientation

  • Where it lives. The app for everyday builds, the terminal for real projects.
  • What working looks like. A preview that runs, versus a red error.
  • Installation. Already covered in pre-work — you should be ready to build.
The debugging reflex
When something breaks, paste the error back and ask Claude to fix it. Errors are normal, not failure.
The AI Internship . Claude Certified DeveloperClaude Code . 21

The core loop

Request, run, fix

1

Request

Describe the outcome and the structure in plain language.

›
2

Run

Claude builds and runs it so you see a real result.

Fix & extend

Change colours, add a section, paste an error and fix. Most work is editing.

Build from the design

The landing page

Copy this prompt
Build a single-page, responsive landing site for Brightbrew Monthly, a $24 per month specialty coffee subscription. Structure: a hero with the headline "Great coffee, every single month" and a "Start your subscription" button; a three-benefit section (freshly roasted, free delivery, a new roast every month); a short "who it is for" section; and a sign-up call to action at the bottom. Warm cream and brown palette, clean, lots of white space. Run it so I can see the preview.
What it producesA runnable, responsive one-page site that matches the Design one-pager.

Customise

From a working state

Change the button colour to a deep espresso brown and add a small FAQ section with three questions above the footer.
Make the "Start your subscription" button link to https://example.com/subscribe.
Most real work is editing something that exists, not building from a blank page.

The debugging reflex

Paste the error, ask for a fix

Copy this prompt
Here is the error I got: [paste the error]. Explain what went wrong in plain English and fix it.
What it producesClaude explains the cause simply and repairs it. This is the habit that unlocks Claude Code for anyone.

Claude Code . Demo C
Code is not only websites

Clean a messy spreadsheet

Copy this prompt
I have a messy CSV of contacts called messy_contacts.csv with inconsistent capitalisation, duplicate people, extra spaces, and inconsistent phone formats. Clean it: standardise names to Title Case, lowercase the emails, format every phone number as (XXX) XXX-XXXX, remove duplicate people, and drop empty rows. Give me the cleaned file back.
What it producesA tidy CSV of about eight unique contacts, consistent casing, uniform phones, no blank rows.
The AI Internship . Claude Certified DeveloperClaude Code . Demo C . 26
Claude Code . You do
Your turn

Run the starter, then change one thing

1
Run the starter: a responsive one-page site with a hero, three feature cards and a CTA, placeholder text, show the preview.
2
Change one thing: the colours, a section, or add a feature.
3
If it breaks, paste the error and ask for a fix. That is the reflex.
Win condition"I ran it and it works." Nothing more is required to succeed.

Section 3

Claude Cowork

Multi-step work that returns finished deliverables, not a single chat answer. Then a routine that runs on its own.
1:40 to 2:15
Claude Cowork
The run layer

An agent, not a chatbot

The mental model
It does the work, it does not just answer about the work. The unit is a delegated job with named outputs.

Claude Cowork
The core loop

Scope, run, check, schedule

1

Scope

Give the goal, the deliverables and the format. Scope sets quality.

›
2

Run

It runs the steps, including research, longer than a chat.

›
3

Check & steer

Review the first pass, correct it, rerun the part that missed.

Schedule

Set a routine once and it runs on its own.

One job, several files

The launch kit

Copy this prompt
I am launching Brightbrew Monthly, a $24 per month specialty coffee subscription. Put together a launch kit as separate deliverables: (1) a landing-page copy doc with three headline options and body copy, (2) five social posts in different angles (benefit, story, founder note, social proof, urgency), and (3) a launch announcement email. First research two or three comparable coffee subscriptions so the positioning is sharp, then write everything. Give me each as its own file.
What it producesThree separate files, preceded by a short research step. It ran multiple steps and returned files, not one reply.

Data to decision

A spreadsheet becomes a recommendation

Copy this prompt
Here is launch_channel_performance.csv with our first month of paid acquisition by channel: spend, clicks, signups, revenue. Analyse it: calculate cost per signup and return on ad spend for each channel, tell me which channels to scale and which to cut next month, and give me a simple chart of signups by channel. Put the recommendation in three bullets at the top.
What it producesScale Newsletter and Instagram, cut Podcast (below break-even), TikTok is expensive per signup. Chart plus three bullets on top.

Two moves that make it land

Scoping, and the routine

Weak
Help me with competitor research for my offer.
Scoped
Research five competitors. For each, capture positioning, price and the main promise. Return a comparison table and a one-page brief on the gap.
The routine
Every weekday at 8am, give me a one-screen brief: today's calendar, anything urgent in my inbox, and the top three things I said I would do yesterday that are still open.
Some work should not wait for you to ask. Set it once, it runs on its own.
