PCafe × CodexThe HTML slide deck skill for Codex

Codex supports Agent Skills natively. With pcafe in ~/.agents/skills/, Codex can make a deck in any repository: write the content, run the check, fix until PASS, and leave one offline HTML file.

Install in CodexSee sample decks

Step one

Install PCafe in Codex

  1. Install globally with the first command (npx skills, Codex already chosen), or unpack into ~/.agents/skills/ with the second.
  2. Codex picks it up on its own; restart it if the skill does not appear.

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 codex -y

or

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

Step two

Working with Codex once it is installed

  • Say “make a deck with pcafe”, or type $pcafe to name the skill.
  • Inside a PCafe project Codex reads AGENTS.md first, which holds the template rules and the definition of done.
  • Have Codex finish with npx pcafe build <name>; dist/ holds the file to send.

A prompt to copy

Use $pcafe to turn the product in README.md into an 8-slide launch deck for prospects. Create a PCafe project, pick templates per AGENTS.md, and 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 Codex

Fixed templates that hold their layout

Codex 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 Codex 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 × Codex: questions

Does it work in Codex cloud tasks?

Yes. Keep the PCafe project in the repository and give the environment Node.js 20.19 or later; Codex reads AGENTS.md and skills/pcafe from the repo.

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 Codex 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 Codex 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.
