What it does

HTML Ppt Zhangzara Vellum is an agent skill from nexu-io/open-design. A humanities lecture: how Renaissance linear perspective reshaped early cartography — sources, argument, and evidence. Built as a decision-grade academic research deck for faculty, graduate seminar.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `template.json`).

It sits in Documents & Office. 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 MIT.

When your agent uses it

  • Documents & Office work in your project

Example prompts

  • “/html-ppt-zhangzara-vellum”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Clone example.html into the user's workspace as the working file.
  2. Replace placeholder content with the user's real headlines, body copy,
  3. Preserve the design system. Never substitute fonts, recolor the palette,
  4. Adjust deck length by duplicating layouts. If the user has more content
  5. Designing missing layouts: if a slide needs a layout the template
  6. Keep the navigation runtime as shipped. If the deck ships an

What it can do on your machine

Read from SKILL.md and the folder at commit 17e2559. 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 Zhangzara Vellum loads about 1.2k tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 336 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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.

Vellum

Deep navy canvas with warm-yellow italic Cormorant serifs and a single dusty teal accent. A quiet, scholarly aesthetic.

A single self-contained HTML deck — typography, palette, decorative system, and slide vocabulary are all tuned together. Mixing layouts across templates breaks the system; stay inside this one.

At a glance

  • Scheme: dark
  • Formality: high
  • Density: low
  • Slides in demo: 9

Best for

Anything that should feel scholarly, literary, and quietly intelligent: research synthesis, white papers, academic and policy briefs, advisory deliverables, longform editorial pieces, founder reflections. Equally strong for any deck — including tech, business, or creator work — that wants a calm, considered atmosphere instead of energetic visuals.

Avoid for

Contexts that need visual heat or pop — the navy + warm-yellow italic-Cormorant aesthetic is intentionally low-tempo.

Workflow

  1. Clone example.html into the user's workspace as the working file.
  2. Replace placeholder content with the user's real headlines, body copy, numbers, names, dates, and section labels. Match existing dimensions when swapping image placeholders.
  3. Preserve the design system. Never substitute fonts, recolor the palette, restructure the layout grid, or strip decorative elements (corner brackets, paper grain, geometric shapes, illustrated SVGs). They are part of the identity.
  4. Adjust deck length by duplicating layouts. If the user has more content than the demo holds, duplicate an existing slide of the most appropriate layout. If less, drop slides from the bottom. Update page-number labels.
  5. Designing missing layouts: if a slide needs a layout the template doesn't have, design it from scratch using the same fonts, palette, decorative vocabulary, spacing rhythm, and component grammar — never bail to a different template.
  6. Keep the navigation runtime as shipped. If the deck ships an assets/deck-stage.js or inline keyboard handler, leave it intact.
