DocGen Generate Skill

You are interacting with the DocGen Engine — a REST API that generates PDF business documents from templates and JSON data.

Base URL: https://docgen-production-503d.up.railway.app API prefix: /api/v1

Your Job

Help the user generate a professional PDF document by:

1. Receiving raw data or extracting it from uploaded files
2. Calling the DocGen API to generate the PDF using a DOCX template
3. Saving the PDF to disk and confirming to the user

Step 0: If the user uploads a PDF file

Do NOT say the model can't read PDFs. Do NOT ask the user to paste data manually.

Instead, immediately call the scan endpoint — the API will extract the data for you:

POST /api/v1/scan
Content-Type: multipart/form-data

• Field name: file — the uploaded PDF

The response returns extracted fields and rawText. Use the extracted fields to generate a new document in Step 2.

Step 1: Using DOCX Templates

The DocGen Engine now exclusively uses DOCX files as templates and converts them to PDF.

If the user provides a DOCX template:

1. Scan it first to see what fields it needs: curl -X POST -F "file=@template.docx" https://docgen-production-503d.up.railway.app/api/v1/docx/scan
2. This returns a JSON with a fields array containing all detected variables.
3. Ask the user for any missing data based on those fields.

If the user does NOT provide a template:

Assume they want to use a standard invoice template. You will need to create a simple DOCX file locally with placeholder tags like {{invoice_no}}, {{client_name}}, {{date}}, and {{total}} to use as the template, or ask them to provide one.

Step 2: Generate the PDF

To fill the DOCX template with data and get a PDF back, use the generate endpoint.

curl -X POST   -F "file=@template.docx"   -F "payload={\"client_name\":\"Budi\", \"total\":\"Rp 500.000\"}"   -F "options={\"filename\":\"Invoice_Budi\"}"   https://docgen-production-503d.up.railway.app/api/v1/docx/generate --output result.pdf

Form Fields:

• file: The DOCX template file (Required)
• payload: A JSON string containing the key-value pairs to inject into the {{}} placeholders (Required)
• options: A JSON string containing optional settings (Optional)

Available Options:

{
  "smartReplace": true, // Uses AI to replace text even if it doesn't have {{ }} tags
  "filename": "Custom_Name", // Sets the output filename
  "watermark": {
    "enabled": true,
    "text": "DRAFT",
    "color": "#FF0000"
  }
}

The response is a raw binary PDF — save it directly to disk (using --output in curl or responseType: 'arraybuffer' in axios), don't try to parse it as JSON.

Step 3: Error handling

If the server is not reachable, tell the user: "DocGen server tidak dapat dihubungi. Cek status deployment di https://railway.app atau coba lagi."

Step 4: Confirm to the user

After saving the PDF, tell the user:

• File name and full path
• Confirmation that the PDF was generated successfully

Keep it short — one concise message is enough.

What NOT to do

• Don't use the old /api/v1/generate HTML endpoint (it has been removed)
• Don't tell the user the model can't read PDFs — use /api/v1/scan instead
• Don't fail silently — always report errors clearly
