PCafe × Grok BuildThe HTML slide deck skill for Grok Build

Grok Build is xAI’s terminal coding agent. It loads skills from ~/.grok/skills/ and ~/.agents/skills/ and reads Claude Code plugins too. With pcafe installed it writes decks with PCafe’s templates and checks until PASS.

Step one

Install PCafe in Grok Build

  1. Install with the first command (npx skills), or unpack the skill into ~/.grok/skills/ with the second.
  2. Already installed through npx skills (~/.agents/skills/) or as a Claude Code plugin? Grok Build reads it automatically.

Afterwards, open a new chat and ask what the pcafe skill does. If it can tell you, the skill is loaded.

npx skills add Web-Casa/pcafe -s pcafe -g -a grok -y

or

mkdir -p ~/.grok/skills && curl -fsSL https://p.cafe/downloads/pcafe-skill.zip -o /tmp/pcafe-skill.zip && unzip -oq /tmp/pcafe-skill.zip -d ~/.grok/skills

Step two

Working with Grok Build once it is installed

  • Type /pcafe, or just say “make a deck with pcafe”.
  • The /skills panel shows whether pcafe is loaded.
  • When the project has AGENTS.md, Grok Build reads it as well and the template rules apply.

A prompt to copy

/pcafe turn the three studies in research/ into a 10-slide market analysis, citing every number. Build once npx pcafe check prints PASS.

Naming the file, the audience, the length and what counts as done helps far more than “make it look nice”.

Why PCafe

Why use PCafe for slides in Grok Build

Fixed templates that hold their layout

Grok Build only writes your content into PCafe’s 270-plus open-source templates; layout, type sizes and colour come from the template, so the deck doesn’t change shape every time.

Delivered only at PASS

Every slide has text limits. Overflow, overlap and tiny type fail the check, and Grok Build trims or splits slides and checks again until PASS.

One offline HTML file

The result is one HTML file that presents with a double-click and no network; it also exports to PDF and editable PowerPoint.

Questions

PCafe × Grok Build: questions

What about Grok Bot?

Grok Bot skills are made inside its own interface, with no documented folder install. Use Grok Build for now.

Is PCafe free?

The open-source version is free for personal and commercial work and keeps a “Made with PCafe” credit. Pro adds 11 paid template packs and lets you remove the credit.

Can I get a PowerPoint file?

Yes. Have Grok Build run npx pcafe pptx <name>; the text comes out as editable text boxes. PDF export works too.

Do I need Node.js?

Building the HTML needs Node.js 20.19 or later, and Grok Build runs the npx commands. Without it, the skill falls back to a storyline and a slide-by-slide outline.

How do I install on Windows?

The npx skills command works in PowerShell too. The unzip one-liners are for macOS and Linux; on Windows, download pcafe-skill.zip and extract it into the matching skills folder under your user folder, for example %USERPROFILE%\.agents\skills.
