Building slides used to eat half my afternoon. Pick a topic, write an outline, fight with layouts, swap fonts, redo the spacing. By slide six, I’d already lost the thread of what I wanted to say. So when I came across this LinkedIn post showing a Claude Skill that hands the entire deck-building job to Gamma in one shot, I had to slow down and actually read it twice.
The original poster walks through a custom Skill they built inside Claude that does something most people are still doing the long way. You give Claude a topic. Claude writes the full outline. Claude sends that outline straight to Gamma through the connector. Gamma spits out a finished, designed, 13-slide presentation. You never open Gamma yourself.
I was honestly a little stunned at how clean the workflow is once it’s set up. No tab switching. No copy-pasting outlines. No “now let me reformat this for Gamma” nonsense. Just topic in, deck out.
Why a Skill beats a regular prompt
A lot of people are still typing the same long slide-prompt into Claude over and over. The creator’s approach flips that. Instead of a prompt you reuse, you save the instructions as a Skill that Claude pulls up automatically whenever you need a deck. It lives inside Claude. It travels with your account. You stop reinventing the wheel every Monday morning.
Think of a Skill like a saved recipe Claude already knows by heart. You don’t re-explain how to chop the onions every time you want soup. Same idea here.
The exact 7-step setup from the post
Here’s the build process the author shared, in order. Each step has a small reason behind it, so you understand why you’re clicking, not just what to click.
- Open Claude. This is your base. Skills live inside the Claude interface, not Gamma, which is the whole trick.
- Go to Customize. This is where Claude keeps your personal extensions. Most people never open this panel, which is why most people are still prompting from scratch.
- Select Skill and click the + button. You’re telling Claude you want to add a new ability, not just send another message.
- Choose Create skill. This opens the builder. You’re now in author mode, not user mode.
- Pick Write skill instructions. This is the route for typing or pasting in your own logic, rather than letting Claude guess.
- Paste the deck-builder skill. The creator’s version handles outline structure, slide count, tone, and the hand-off to Gamma through the connector.
- Add a title and instructions, then save. The title is how Claude finds it later. The instructions are what Claude reads every time you ask for a deck.
That’s the whole setup. Seven clicks, one paste, and you’re done. The author mentioned this Skill is one of five they’ve packaged up, all aimed at making Claude do the boring, repeatable parts of your workweek.
What happens when you actually use it
Once the Skill is saved, the flow is almost embarrassingly short. You drop a topic into Claude. Claude reads the Skill, writes the full outline behind the scenes, and routes that outline to Gamma through the connector. Gamma generates the slides. Designed. Laid out. Ready to present.
13 slides was the number this LinkedIn creator showed in their demo. Could be more, could be fewer, depending on how you write the Skill. The point is you set the rules once and Claude follows them every time.
The shift here is small but huge: you stop being the operator and start being the editor. Claude operates Gamma. You just review the output.
Where this actually saves you time
I think this is a game-changer for a few specific situations:
- Weekly team updates. Same structure every week, different content. A Skill nails the structure once and you stop rebuilding it.
- Sales pitches. Drop the prospect’s industry into Claude, get a tailored deck back. No more “let me update the template real quick.”
- Internal training. Onboarding decks, policy refreshers, quarterly reviews. Anything that follows a repeatable shape.
- Conference talks and webinars. Give it the title and three bullet points. Let it draft the visual scaffolding so you can focus on the talk track.
- Client reports. Same skeleton, fresh data, every month. The Skill keeps the look consistent without manual fiddling.
A few tips before you build your own
The savvy professional behind this didn’t say it directly, but a few things stand out from how they framed the workflow:
- Be specific in the Skill instructions about tone, slide count, and audience. Generic in, generic out.
- Decide upfront whether you want Claude to write speaker notes too, or just visible slide text.
- If you build multiple Skills, name them clearly so you can call the right one without thinking. “Sales Deck Builder” beats “Skill v3.”
- Test the Skill on two or three topics before trusting it for real work. You’ll spot weird patterns fast.
The reason this matters goes beyond decks. Skills inside Claude are turning into a quiet productivity layer that most people haven’t noticed yet. Anyone who builds a small library of personal Skills early is going to feel like they have a second brain by the end of the year.
