Slide Editing
Documentsslide-editingSlide Editing is an Agent Skill for documents published in the BuilderIO/agent-native repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.
How to edit individual slides -- content formatting, HTML styling rules, updating slide content in the database.
How to use this skill
Bring this guide into your coding agent with a prompt tailored to the tool you use.
- Open your project in Codex.
- Copy and paste the prompt below.
- Review files and risks before approving any action.
Inspect the Agent Skill at https://github.com/BuilderIO/agent-native/blob/HEAD/templates/slides/.agents/skills/slide-editing/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/slide-editing, but wait for my approval before writing files or running scripts.
Copying this prompt does not install or run the skill. Review third-party files before use.
Slide Editing
Slides are HTML content stored inside the deck JSON. Each slide's content field is a self-contained HTML string that renders at 1920x1080 resolution.
Slide HTML Structure
Every slide uses this wrapper:
<div class="fmd-slide" style="padding: 80px 110px; display: flex; flex-direction: column; justify-content: flex-start;">
<!-- Slide content here -->
</div>
Styling Rules
All generated slides follow these conventions:
| Element | Style |
|---|---|
| Background | bg-[#000000] (pure black) |
| Font | font-family: 'Poppins', sans-serif on all text |
| Section labels | font-size: 16px; font-weight: 700; letter-spacing: 3px; text-transform: uppercase; color: #00E5FF |
| Headings | font-size: 40px; font-weight: 900; color: #fff; line-height: 1.15; letter-spacing: -1px |
| Title slides | font-size: 54px; font-weight: 900 with justify-content: center |
| Bullet points | ● character (8px, white), gap: 20px, font-size: 22px, color: rgba(255,255,255,0.85) |
| Sub-bullets | ○ (open circle), padding-left: 36px |
| Bold terms | <strong style="font-weight: 800; color: #fff;">Term</strong> + description in rgba(255,255,255,0.55) |
| Accent color | #00E5FF (cyan) for section labels, emphasis, highlights |
Updating a Slide
To edit a slide's content:
- Inspect the current context: call
view-screento get the active deck, slide ID, HTML, and anyslides-selectionstyle/edit target. - Modify the content HTML string for the intended slide.
- Update the slide with the
update-slideaction usingdeckId,slideId, andfullContent. Do not write deck rows directly and do not add raw/api/decks/:idPUT calls for normal slide edits. - For browser/editor code, enqueue granular deck operations through
patch-deck/DeckContext.tsxinstead of replacing the whole deck JSON.
Image Placeholders
For visual elements (diagrams, charts, photos), use placeholder divs:
<div class="fmd-img-placeholder" style="width: 100%; height: 300px; border-radius: 12px;">
Description of the image
</div>
Never try to recreate complex visuals with raw HTML/CSS. Use placeholders and generate proper images via the image generation flow.
Slide Layouts
Common layout patterns:
- Title slide: Single centered heading,
justify-content: center - Section divider: Large single word, centered
- Content: Section label + heading + bullet list
- Two-column: Flex row with
gap: 40px, text left, image right - Table: CSS grid with alternating row backgrounds
