Calls npm

What it does

For each target format it installs the matching package, such as one for converting JSON to PPTX, DOCX or XLSX, builds a JSON layout spec against a bundled schema reference, then writes and runs a short Node.js script that passes that JSON into the matching PaperJSX engine. The execution model stays JSON in, document file out, and it avoids writing imperative calls against the PaperJSX API directly.

After generation it always verifies the output file exists and is non-zero bytes with a filesystem check, and surfaces the engine's full error message to the user if generation throws, rather than guessing at the cause.

When your agent uses it

Generating a PowerPoint deck from structured content
Creating a Word document or Excel spreadsheet from JSON data
Producing a PDF invoice or report from a layout spec

Example prompts

“Generate a PPTX deck from this JSON outline using PaperJSX.”
“Turn this JSON spec into an Excel spreadsheet with charts.”
“Create a PDF invoice from this JSON layout and confirm the file was written.”

Requirements

Node.js
The format-specific PaperJSX package

Workflow steps

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

Build a JSON layout spec matching the schema in references/json-schema.md
Write a Node.js script that passes the JSON to the PaperJSX engine
Run the script to generate the output file
Validate the output file exists and is non-zero bytes

What it can do on your machine

Read from SKILL.md and the folder at commit 0930e13. 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
Shell commands in SKILL.md call:
- npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
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

PaperJSX Document Generator loads about 842 tokens when it runs, and up to ~4.2k if it reads all its reference files. Until then it costs about 33 tokens; SKILL.md has 191 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~33
When it runs · the whole SKILL.md, loaded when a task matches: ~842
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~4.2k

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.

name: paperjsx
description: Generate PPTX presentations, DOCX documents, XLSX spreadsheets, and PDF reports from structured JSON input using PaperJSX.

PaperJSX Document Generation

Generate professional documents from JSON layout specs. PaperJSX is generation-only — it creates new files, it does not edit existing ones.

Triggers

Use this skill when the user asks to:

Create a presentation or generate slides
Make a PPTX or PowerPoint file
Create a Word document or DOCX
Generate an Excel spreadsheet with charts
Create a JSON to PPTX, JSON to DOCX, or JSON to XLSX file
Generate a PDF invoice, report, or chart document

Install

Install the format-appropriate package:

bash

# Presentations
npm install @paperjsx/json-to-pptx

# Word documents
npm install @paperjsx/json-to-docx

# Spreadsheets
npm install @paperjsx/json-to-xlsx

# PDF documents
npm install @paperjsx/json-to-pdf

How it works

Build a JSON layout spec matching the schema in references/json-schema.md
Write a Node.js script that passes the JSON to the PaperJSX engine
Run the script to generate the output file
Validate the output file exists and is non-zero bytes

Do not write imperative PaperJSX API code. The execution model is always: JSON spec in, document file out.

Example: PPTX generation

javascript

import { PaperEngine } from "@paperjsx/json-to-pptx";
import fs from "node:fs";

const spec = {
  type: "Document",
  meta: { title: "Q4 Review" },
  slides: [
    {
      type: "Slide",
      children: [
        { type: "Text", content: "Q4 2025 Business Review", style: { fontSize: 36, bold: true } }
      ]
    }
  ]
};

const buffer = await PaperEngine.render(spec);
fs.writeFileSync("presentation.pptx", buffer);
console.log("Generated presentation.pptx");

Example: DOCX generation

javascript

import { renderToDocx } from "@paperjsx/json-to-docx";
import fs from "node:fs";

const result = await renderToDocx({
  type: "DocxDocument",
  pageSize: "a4",
  orientation: "portrait",
  pages: [
    {
      elements: [
        { type: "heading", level: 1, text: "Quarterly Report" },
        { type: "paragraph", text: "Section content here." }
      ]
    }
  ]
});

fs.writeFileSync("report.docx", result.buffer);
console.log("Generated report.docx");

Example: XLSX generation

javascript

import { SpreadsheetEngine } from "@paperjsx/json-to-xlsx";
import fs from "node:fs";

const spec = {
  meta: { title: "Revenue Data", creator: "PaperJSX" },
  sheets: [{
    name: "Revenue",
    rows: [
      { cells: [{ value: "Quarter" }, { value: "Revenue" }] },
      { cells: [{ value: "Q1 2026" }, { value: 420000 }] },
      { cells: [{ value: "Q2 2026" }, { value: 510000 }] }
    ]
  }]
};

const buffer = await SpreadsheetEngine.render(spec);
fs.writeFileSync("revenue.xlsx", buffer);
console.log("Generated revenue.xlsx");

Validation

After generating any file, always verify:

javascript

import fs from "node:fs";

const stats = fs.statSync("output.pptx");
if (stats.size === 0) {
  throw new Error("Generated file is empty");
}
console.log(`Output file: ${stats.size} bytes`);

If the engine throws an error, surface the full error message to the user.

Schema reference

See references/json-schema.md for the complete JSON layout spec schema for all supported formats.
