Learn how to use Claude Code, Opus 5.5 and skills to write articles, create social media content, prototype features and create product demo videos and promos
You use Claude or ChatGPT daily: paste, improve, copy, repeat. Meanwhile, others build landing pages, demos and 20 blog posts in an afternoon with Claude Code.
Since Opus 5.5 came out, the feed is full of animated shorts drawn in code, auto-generated feature screenshots and 5-minute landing pages.
This guide is for product managers, designers, video editors and content writers new to Claude Code. No coding or terminal needed, and each step ends with a clear result.
Web AI Chat vs Claude Code in 30 seconds
Claude Code is running on your computer and has an access to your system.
Web AI chat
Claude Code
Where it works
A browser tab
A folder on your computer
What you get back
Text you copy and paste
Real files: documents, images, videos, web pages
Context
What you paste into the message
Everything in the folder, plus notes you leave for it
Tools
Mostly none
Runs programs, browses the web, installs what it needs, records screen and make screenshots
Step 1. Install the desktop app
Where to use it: Claude Code runs in the terminal, as a desktop app, or in code editors like VS Code and Cursor.
Best for beginners: If the terminal feels intimidating, pick the desktop app. It works the same, just with buttons and a chat window.
Install Claude Desktop:
1. Download the Claude desktop app from claude.ai/download for Mac or Windows
2. Sign in with your Claude account. Claude Code needs a paid plan: Pro is enough to learn, Max gives you more usage once you run it every day
3. Open the Code tab in the sidebar
Outcome: the desktop app is open on the Code tab and asks you to pick a folder.
Step 2. Create a folder for your work
How Claude works: It works inside a folder, where it reads and saves everything.
How to set it up:
Create a folder, like Documents/claude-work
Add your brief, brand guide, past posts or screenshots
Select it in the Code tab
Tip: Start with a fresh folder, not your whole Desktop, to keep Claude focused.
Outcome: Claude Code is pointed at a folder that holds your knowledge base.
Step 3. Run your first task
The key habit: Ask for a finished file, not an answer. It changes everything.
Start with a link: Paste a website address and Claude reads the page and works from it, no files needed. Try one of these with your product or a competitor’s:
Then use your files: Once that works, point Claude to the files in your folder:
While it works, you’ll see each step: reading files, running tools, installing what it needs. Before changing a file or running a command, it asks for permission. Not sure? Ask “what will this do?” before you click allow.
When it’s done, open the file and give feedback like you would to a teammate: “shorter headline”, “use our green”, “captions cover the logo”. It edits the same file instead of starting over.
Learn markdown.
You'll see ".md" extension a lot. It's a markup language really close to natural text. You'll need to learn to read these files to validate output.
Pick the effort level.
Effort sets how long Claude thinks before it acts: low, medium, high, xhigh or max. Opus 5.5 starts at medium, which is fine for posts and quick edits. Switch to high or max for research, a full landing page or a video, and to low when you just need a fast answer. Change it with Cmd+Shift+E in the desktop app or by typing /effort.
Outcome: a real file in your folder that you can open, share or keep editing.
Step 4. Give it context once, not every time
Why it matters: In chat, you re-explain your company every conversation. In Claude Code, you write it down once.
How to set it up: Ask Claude: "Create a CLAUDE.md file in this folder with what you should know about me and my work. Ask me questions first."
It will interview you and save the answers. Claude reads CLAUDE.md at the start of every session, so it remembers:
Who you are and who the audience is
Your product in 3 sentences
Tone of voice and words you never use
Brand colors and fonts
Where things live in the folder
Keep it growing: Corrected Claude twice on the same thing? Say “add this to CLAUDE.md”.
Outcome: Claude starts every task already knowing your product, audience and style.
Step 5. Install skills
What a skill is: A skill is a saved playbook that teaches Claude to do a task like a pro. Claude uses it automatically when your request matches.
Where to find skills: Thousands of free skills are on GitHub. A great start for startup teams is marketingskills by Corey Haines, covering copywriting, landing pages, SEO, emails, pricing and launches.
How to install one: You don’t need to know how installing works. Paste this into Claude Code:
How to use it: Start a new session, then try:
Claude downloads them and puts them in the right place. Start a new session, then try:
To see every installed skill type / in the message box and pick one from the list.
A few more worth trying:
Anthropic’s file skills for real Word, PowerPoint, Excel and PDF files
Video skills like Hyperframes or Remotion that turn a script or URL into an MP4
Your own skills. Done a task well 3 times? Ask Claude to “turn this into a skill called weekly-report”. Next time, “make the weekly report” is all you need.
Images and videos take time to make, usually 5–10 minutes and up to an hour for video, so give Claude the full context upfront.
Outcome: Claude works like a specialist, and you build a library of repeatable workflows.
Step 6. Connect your tools with MCP
The problem: Your real context lives across Notion, Google Drive, Slack, Linear, Figma and analytics tools. Copying it into a folder by hand wastes hours.
What MCP is: MCP (Model Context Protocol) connects Claude to your other apps. Once connected, Claude can:
Search and read them on its own
Take actions, like creating a ticket, updating a doc or posting to Slack
What it works with: Most popular tools already support it, including Notion, Google Drive, Gmail, Slack, Linear, Jira, Figma, HubSpot and PostHog.
How to connect MCP:
1. In the Claude app, open Settings, then Connectors
2. Pick the tools you use every day and sign in to each one. Connectors you add here also work in Claude Code
3. In a Claude Code session, type /mcp to see what's connected and sign in to anything that still needs it
4. If a tool isn't in the list, search for "\[tool name\] MCP server", paste the link into Claude Code and ask it to add the server for you
How to use it: Reference connected tools in your prompts the same way you’d reference a file:
Why it matters: The difference is huge. Content built from real customer quotes and numbers reads like it was written by someone on your team.
Stay safe: Connect only what each task needs. Claude asks before acting in another app, so read those requests carefully, especially anything that sends, posts or deletes.
Outcome: Claude works from your team’s live context, not just what you paste in.
Step 7. Avoid AI slop
Great output needs someone steering. Without direction, Claude Code goes generic. These rules keep it sharp.
Outcome: output that sounds like you and looks like your brand, not like every other AI post.
What a solid week with Claude Code looks like
Once the basics work, the jobs start to stack:
Product manager
Connects Linear, Jira and PostHog through MCP
Turns tickets into interactive prototypes for devs
Writes tickets with clear acceptance criteria
Drafts changelogs with demos
Asks questions about analytics
Designer
Turns a Figma screenshot and brand guide into a working landing page
Creates social cards and OpenGraph images in the brand’s fonts
Designs new features as live prototypes and hands off a Vercel link instead of Figma
Video editor
Gets rough cuts and captions
Resizes videos for every platform
Builds 15-second promos from the real product UI
Generates animated B-roll
Content writer
Researches topics
Drafts posts in the house voice
Turns each post into 5 social posts
Generates cover images and illustrations
None of this needs code from you. It needs clear briefs, good references and the patience to give feedback 2 or 3 times.
Build a habit
Learning Claude Code takes a few weeks. Things won’t always work at first, and that’s normal. Use it a little more each day until it clicks and you can’t imagine working without it.
