Docling-Agent

Docling-agent simplifies agentic operation on documents, such as writing, editing, summarizing, etc.

Note

This package is still immature and work-in-progress. We are happy to get comments, suggestions, code contributions, etc!

Features

• Document writing: Generate well-structured reports from natural prompts and export to JSON/Markdown/HTML.
• Targeted editing: Load an existing Docling JSON and apply focused edits with natural-language tasks.
• Schema-guided extraction: Extract typed fields from PDFs/images using a simple schema and produce HTML reports. See examples on curriculum_vitae, papers, invoices, etc.
• Model-agnostic: Plug in different backends via Mellea model_ids (e.g., OpenAI GPT OSS, IBM Granite).
• Simple API surface: Use agent.run(...) with DoclingDocument in/out; save via save_as_* helpers.
• Optional tools: Integrate external tools (e.g., MCP) when available.

Quick start (writing):

from mellea.backends import model_ids
from docling_agent.agents import DoclingWritingAgent

agent = DoclingWritingAgent(model_id=model_ids.OPENAI_GPT_OSS_20B)
doc = agent.run("Write a one-page summary about polymers in food packaging.")
doc.save_as_html("report.html")

Installation

Getting started

Below are three minimal, end-to-end examples mirroring the scripts in the examples folder. Each snippet shows how to initialize an agent, run a task, and save the result.

Write a new document (see example):

from mellea.backends import model_ids
from docling_agent.agents import DoclingWritingAgent

agent = DoclingWritingAgent(model_id=model_ids.OPENAI_GPT_OSS_20B)
doc = agent.run("Write a brief report on polymers in food packaging with a small comparison table.")
doc.save_as_html("./scratch/report.html")

Edit an existing document (see example):

Use natural-language tasks to update a Docling JSON. You can run multiple tasks to iteratively refine content, structure, or formatting.

from pathlib import Path
from mellea.backends import model_ids
from docling_core.types.doc.document import DoclingDocument
from docling_agent.agents import DoclingEditingAgent

ipath = Path("./examples/example_02_edit_resources/20250815_125216.json")
doc = DoclingDocument.load_from_json(ipath)

agent = DoclingEditingAgent(model_id=model_ids.OPENAI_GPT_OSS_20B)
updated = agent.run(task="Put polymer abbreviations in a separate column in the first table.", document=doc)
updated.save_as_html("./scratch/updated_table.html")

Extract structured data with a schema (see example):

Define a simple schema and provide a list of files (PDFs/images). The agent produces an HTML report with extracted fields.

from pathlib import Path
from mellea.backends import model_ids
from docling_agent.agents import DoclingExtractingAgent

schema = {"invoice-number": "string", "total": "float", "currency": "string"}
sources = sorted([p for p in Path("./examples/example_03_extract/invoices").rglob("*.*") if p.suffix.lower() in {".pdf", ".png", ".jpg", ".jpeg"}])

agent = DoclingExtractingAgent(model_id=model_ids.OPENAI_GPT_OSS_20B)
report = agent.run(task=str(schema), sources=sources)
report.save_as_html("./scratch/invoices_extraction_report.html")
