Let Antigravity Agents Convert Existing Content Into Presentations

When the source material already exists — a competitor's blog post, a research report, a YouTube conference talk, a documentation page — Antigravity's agents shouldn't start a deck from scratch. Felo Content to Slides extracts the structure and key points from any URL or transcript and generates a .pptx the team can review and refine.

How it works

What felo-content-to-slides adds to Antigravity

Six capabilities that convert existing content into structured presentations without manual reformatting.

Content-to-deck conversion

Converts docs, articles, or research into a structured slide deck automatically.

Intelligent slide splitting

Detects natural section breaks and maps them to slides — no manual chunking.

Headline extraction

Pulls key statements as slide titles, keeping body text as supporting detail.

Visual placeholder suggestions

Flags where charts or images would strengthen the narrative.

Export-ready output

Returns PPTX or Google Slides link directly in the agent response.

SKILL.md auto-routing

Activated when the agent task involves converting existing content into a presentation.

Installation

Three steps to converting existing content into decks inside Antigravity

Once installed, felo-content-to-slides activates when an agent task involves converting a known source into a presentation — no blank-slate prompting needed.

Method 1 · Terminal

Install via command line

Clone the Felo skills repo and copy the skill into your global Antigravity skills directory.

Terminal
# Clone the Felo skills repository git clone https://github.com/Felo-Inc/felo-skills.git # Copy this skill to your global Antigravity skills folder cp -r felo-skills/felo-content-to-slides ~/.gemini/antigravity/skills/
Installs to ~/.gemini/antigravity/skills/ — available across all your projects
Method 2 · Agent prompt

Let the agent install it for you

Paste this prompt directly into Antigravity. The agent clones the repo and copies the skill automatically.

Paste into Antigravity
Install https://github.com/Felo-Inc/felo-skills into my global Antigravity skills directory.
The agent handles cloning, copying, and directory setup — no terminal needed
1

Copy the skill into .agent/skills/

Clone the Felo skills repo and copy felo-content-to-slides into .agent/skills/ for team-wide access. The SKILL.md description activates it when a task involves converting existing content into a presentation.

2

Set your Felo API key

Add FELO_API_KEY to your environment. The skill handles content extraction, structure inference, and .pptx generation — you point it at the source, it builds the deck.

3

Chain it with felo-web-fetch or felo-youtube-subtitling

The natural Antigravity workflow: one agent fetches a page or extracts a video transcript, another passes it to felo-content-to-slides to generate the deck. The Agent Manager chains these automatically — source to presentation in one task.

No configuration needed. The SKILL.md file inside the skill folder tells Antigravity's Agent Manager when to activate it. Once the folder is in place, the agent routes to the skill automatically based on your prompt.

FAQ

Felo Content to Slides in Google Antigravity — FAQ

felo-slides starts from a prompt — you describe the deck you want and the agent builds it. felo-content-to-slides starts from existing source material — a URL, an article, a transcript. Use content-to-slides when the story already exists somewhere; use felo-slides when you're creating from scratch.

Turn existing content into decks — let Antigravity agents do the conversion

Install felo-content-to-slides in .agent/skills/ and let the Agent Manager convert web pages, articles, and video transcripts into structured presentations automatically.

One API key. Commit to .agent/skills/ and your agents can convert any existing source into a shareable .pptx without starting from scratch.
