open-slide is a React-based slide framework that lets coding agents create presentations from natural-language descriptions. It provides the canvas, scaling, navigation, hot reload, and presentation mode while agents write the slide components. The catalogue skills and instructions support agent-based slide authoring and revision.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00106 | $0.02310 |
| Opus 5 | $0.00053 | $0.01155 |
| Sonnet 5 | $0.00021 | $0.00462 |
| Haiku 4.5 | $0.00011 | $0.00231 |
Grade A, and why
create-slide 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 6d 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 — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create a slide in open-slide
This skill owns the workflow for drafting a new deck. The technical reference — file contract, 1920×1080 canvas, type scale, palette, layout, assets — lives in the slide-authoring skill. Read that skill whenever you need details on how a page is structured. This skill assumes you'll consult it before writing code.
You only write files under slides/<id>/. Never modify package.json, open-slide.config.ts, or existing slides.
Step 1 — Pick a theme
List files under themes/. If any theme markdown files exist (anything other than README.md), call AskUserQuestion with each theme id as an option plus a final "no theme — design from scratch" option. (AskUserQuestion holds at most 4 options — with 4+ themes, offer the 3 most topic-relevant plus "no theme"; the auto-added "Other" lets the user name any omitted theme.)
- If the user picks a theme: read
themes/<id>.mdend-to-end. The theme's palette, typography, layout, and Title/Footer components are now authoritative — copy them directly into the slide. If the theme declares a webfont import, load it perreferences/webfonts.mdinslide-authoring(module-level, slide-keyed injection) — don't let the slide silently fall back to system fonts. Also settheme: '<theme-id>'on themetaexport inindex.tsx(e.g.export const meta: SlideMeta = { title: '…', createdAt: '…', theme: '<theme-id>' };—createdAtper the file contract inslide-authoring) so the slide back-links to the theme (chip on the slide card + listing on/themes/<id>). In Step 2, skip the aesthetic direction question (the theme already commits to one direction); you still need the topic itself, so confirm it before moving on. Page count and text density are independent of theme — ask those normally. For motion, if the theme's Motion section commits to a philosophy, present it as the "(Recommended)" option and reuse the theme's paste-ready keyframes; the user can still override. - If the user picks "no theme", or
themes/contains no theme markdown files: proceed to Step 2 unchanged.
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.

create-slide is a skill published in the GitHub repository 1weiho/open-slide (7,390 stars, last pushed yesterday), licensed MIT. It adds 106 tokens to every session and 2,310 once invoked, about $0.0005 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.

tmux
Remote-control tmux sessions for interactive CLIs by sending keystrokes, capturing pane output, and managing terminal multiplexer windows. Enables parallel coding-agent orchestration, background process management, and REPL interaction via sockets. Use when the agent needs to launch, monitor, or coordinate…

Transfer a blog post from Notion to the Wasp blog. Fetches content, downloads and optimizes images, and creates a properly formatted MDX file.
channels-setup
Use when a developer wants to build their first CopilotKit Channels agent and get it answering in Slack or Microsoft Teams — "set up a channel", "connect my agent to Slack", "get my agent into Teams", or starting from nothing and wanting a working channel end to end. Covers the whole path: inspecting or scaffolding…
