Oh My PPT is a local-first desktop application that uses AI to create, edit, present, and export editable HTML-based slide presentations. It is for people making presentations, lessons, stories, reports, or pitches who want to describe their content and then adjust the resulting pages, visuals, animations, and layouts.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.02667 |
| Opus 5 | $0.00022 | $0.01333 |
| Sonnet 5 | $0.00009 | $0.00533 |
| Haiku 4.5 | $0.00004 | $0.00267 |
Grade A, and why
oh-my-ppt-data-anim scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Oh My PPT Data Anim
For deeper examples (trigger choice guide, scripted animation patterns, timing tips), read references/data-anim.md.
When to use
- Adding entrance or emphasis animation to slide elements
- Creating staggered reveal sequences for cards, steps, or list items
- Repairing broken or unsupported animation
When not to use
- Layout-only changes with no motion intent
- Adding animation in edit mode unless the user asks, the page already has animation, or you are fixing broken animation
30-second decision checklist
Before adding animation, answer these:
- Reading path: which elements should appear first, second, third? Animation follows the reading path.
- Trigger: load (default), stagger (repeated items), with (group together), after (sequence), click (presentation control only)?
- Type: fade, slide, scale, fly, wipe, zoom, bounded emphasis — match the visual intent.
- Duration: 300–1200ms. Shorter for subtle, longer for dramatic.
How to add animation
1. Declarative data-anim — preferred
Add data-anim attributes directly on HTML elements. This works in preview and exports deterministically to PPTX.
<div data-anim="fade-up" data-anim-delay="stagger(90)">Card 1</div>
<div data-anim="fade-up" data-anim-delay="stagger(90)">Card 2</div>
<div data-anim="fade-up" data-anim-delay="stagger(90)">Card 3</div>
2. Supported animation types
fade, fade-up, fade-down, fade-left, fade-right, scale-in, slide-up, slide-down, slide-left, slide-right, fly-in, wipe, zoom-in, spin-in, grow-shrink-soft, grow-shrink, grow-shrink-strong, pulse-soft, pulse, pulse-strong, exit-fade, exit-scale, exit-zoom, exit-wipe, exit-fly, path
3. Attributes
| Attribute | Values | Notes |
|---|---|---|
data-anim |
type from supported list | required |
data-anim-trigger |
load, click, with, after |
omit for load |
data-anim-sequence |
with, after |
preferred load-order control for new content |
data-anim-click-group |
stable token such as step-1 |
only for contiguous click animations that should reveal on the same click |
data-anim-from |
left, right, top, bottom, center |
direction/origin |
data-anim-delay |
ms or stagger(N) |
stagger for repeated items |
data-anim-stagger |
ms | preferred new declarative stagger gap |
data-anim-duration |
ms | prefer 300–1200 |
data-anim-path |
inline linear path string such as M 0 0 L 120 30 |
only for path type |
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

oh-my-ppt-data-anim is a skill published in the GitHub repository arcsin1/oh-my-ppt (1,946 stars, last pushed 6d ago), licensed Apache-2.0. It adds 43 tokens to every session and 2,667 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
