How to make slides with Claude:

_

Step 1. Open Claude & build your first Claude skill.

Step 2. Go to "Customize."

Step 3. Select "Skill" → click "+".

Step 4. Choose "Create skill."

Step 5. Pick "Write skill instructions."

Step 6. Paste this deck-builder prompt:

I want you to create a Claude skill (a SKILL .md file) for building presentation decks. The skill should follow the exact format and structure I'm about to describe.

Here's what I need:

### 1. ABOUT ME AND MY DECKS

What type of decks I build: [DESCRIBE YOUR TYPICAL PRESENTATIONS. Examples: "educational workshops about marketing automation," "sales pitch decks for my SaaS product," "internal training decks for onboarding new hires," "conference talks about design systems"]

My audience: [WHO WATCHES THESE DECKS? Examples: "non-technical founders," "enterprise sales teams," "college students learning UX," "C-suite executives"]

My brand/voice: [HOW DO YOU SOUND? Examples: "casual and direct, like texting a smart friend," "polished but not corporate," "academic but accessible," "funny and irreverent." If you have a brand voice doc, paste the key rules here instead.]

### 2. SKILL STRUCTURE

The skill must follow this exact structure:

YAML frontmatter with:

- name: deck-builder

- description: A "pushy" trigger description that fires whenever I mention decks, slides, presentations, talks, workshops, or anything slide-related. Include specific trigger phrases. Exclude content types I don't want it to fire on.

The skill body must have these sections in this order:

Section: Overview — One paragraph. What this skill does and how the process works. Keep it direct.

Section: Reference files (OPTIONAL) — [IF YOU HAVE VOICE/STYLE DOCS YOU WANT THE SKILL TO READ, LIST THEM HERE WITH THEIR FILENAMES AND A ONE-LINE DESCRIPTION OF EACH. Example: "BRAND_VOICE .md — Hard rules for tone and vocabulary" / "BEST_DECKS .md — Examples of decks that performed well." IF YOU DON'T HAVE THESE, DELETE THIS SECTION.]

Section: Step 1 — Gather the brief. Before writing anything, the skill must collect these inputs from me. Ask for anything missing:

Required inputs:

- Topic (one core idea)

- Audience (who's in the room)

- Length (slide count or talk duration)

- Key takeaways (what the audience should be able to DO after)

Optional inputs:

- Tone note

- Existing content to pull from (blog posts, docs, notes)

- Visual style preference for Gamma

- [ADD ANY OTHER INPUTS YOU ALWAYS NEED. Examples: "Brand colors," "Whether to include a Q&A slide," "Client name for title slide"]

Section: Step 2 — Build the outline. This is the core of the skill. Rules:
