What it does
HTML Ppt Tech Sharing is an agent skill from nexu-io/open-design. OpenDesign internals: how the agent stream, sandbox, and artifacts work — an engineering deep-dive talk. Built as a decision-grade AI literacy deck for engineers, dev community.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.
It sits in Documents & Office, covering PowerPoint presentations. The repository describes itself as: 🎨 Best DeepSeek Harness Design Plugin. The open-source Claude Design alternative. 🖥️ Local-first desktop app. 🖼️ Your coding agent becomes the design engine: prototypes… The licence is Apache-2.0.
When your agent uses it
- Tasks that involve PowerPoint presentations
Example prompts
- “/html-ppt-tech-sharing”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Read the master skill first. All authoring rules live in
- Start from the matching template folder
- Bring the shared runtime with the template. The upstream
- Pick a theme. Default tokens look fine; if the user wants a different
- Replace demo content, not classes. The .tpl-tech-sharing scoped CSS only
- Speaker notes go inside or — never as visible text on the slide.
What it can do on your machine
Read from SKILL.md and the folder at commit 3449fa6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
HTML Ppt Tech Sharing loads about 1.3k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 377 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

HTML PPT · Tech Sharing
A focused entry point into the html-ppt master skill that lands the user directly on the tech-sharing full-deck template.
When this card is picked
The Examples gallery wires "Use this prompt" to the example_prompt above. When you accept that prompt, this card is the right pick if the user wants exactly the visual identity of tech-sharing (see the upstream full-decks catalog for screenshots and rationale).
How to author the deck
- Read the master skill first. All authoring rules live in
design-templates/html-ppt/SKILL.md— content/audience checklist, token rules, layout reuse, presenter mode, the keyboard runtime, and the "never put presenter-only text on the slide" rule. - Start from the matching template folder:
design-templates/html-ppt/templates/full-decks/tech-sharing/— copyindex.htmlandstyle.cssinto the project, keep the.tpl-tech-sharingbody class. - Bring the shared runtime with the template. The upstream
index.htmllinks the shared CSS/JS via../../../assets/...because it sits three folders deep insidedesign-templates/html-ppt/templates/full-decks/. Once you copyindex.htmlinto the project, those parent-relative URLs no longer resolve andbase.css,animations.css, andruntime.jswill 404 — meaning the deck never activates and slide navigation is dead. Pick one of these two recipes per project:- Recipe A — copy + rewrite (preferred): copy
design-templates/html-ppt/assets/fonts.css,design-templates/html-ppt/assets/base.css,design-templates/html-ppt/assets/animations/animations.css, anddesign-templates/html-ppt/assets/runtime.jsinto a project-localassets/(withassets/animations/animations.css), then rewrite the four<link>/<script>tags inindex.htmlfrom../../../assets/...to the matching project-local paths (assets/fonts.css,assets/base.css,assets/animations/animations.css,assets/runtime.js). - Recipe B — inline: read the same four files and replace each
<link rel="stylesheet" href="../../../assets/...">with a<style>...</style>containing the file's contents, and the<script src="../../../assets/runtime.js">with a<script>...</script>containingruntime.js. Yields a single self-containedindex.html. Either way, do not ship the upstream../../../assets/...URLs verbatim into a project artifact — they only work in-tree.
- Recipe A — copy + rewrite (preferred): copy
- Pick a theme. Default tokens look fine; if the user wants a different
feel, swap in any of the 36 themes from
design-templates/html-ppt/assets/themes/*.cssvia<link id="theme-link">and letTcycle. - Replace demo content, not classes. The
.tpl-tech-sharingscoped CSS only recognises the structural classes shipped in the template — keep them. - Speaker notes go inside
<aside class="notes">or<div class="notes">— never as visible text on the slide.
