seele-scholar-agent 0.11.2

An academic paper writing agent based on LangGraph

seele-scholar-agent

English | 简体中文 | 日本語

LangGraph-based academic paper writing agent for topic proposal, literature retrieval, outline planning, section drafting, review loops, consistency checks, and reference generation.

Features

• Search papers from OpenAlex, Semantic Scholar, ArXiv, and custom retrievers.
• Propose concrete paper topics from broad research directions.
• Generate structured outlines with suggested figures and tables.
• Draft sections with numbered citations and optional RAG context.
• Review sections, revise drafts, and cap revisions per section.
• Generate references with CrossRef metadata enrichment.
• Check terminology, logic, and citation consistency after references are generated.
• Stream node output with astream() for UI integration.

Install

git clone https://github.com/onekyuu/seele-scholar-agent
cd seele-scholar-agent

uv sync

For development dependencies:

uv sync --extra dev

Configuration

This package only owns agent-level configuration. LLM keys and models are injected by the caller.

Agent .env file:

cp src/seele_scholar_agent/.env.example src/seele_scholar_agent/.env

Supported agent variables:

Variable	Description	Default
SEMANTIC_SCHOLAR_API_KEY	Optional Semantic Scholar API key	empty
MAX_REVISIONS	Max review cycles per section	3

Example caller environment:

OPENAI_API_KEY=sk-...
OPENAI_MODEL=gpt-4o-mini
OPENAI_BASE_URL=https://api.openai.com/v1

Any OpenAI-compatible endpoint can be used through ChatOpenAI.

Quick Start

Run the no-interrupt workflow:

export OPENAI_API_KEY="sk-..."
export SCHOLAR_TOPIC="large language model interpretability"
export SCHOLAR_LANGUAGE="zh"

uv run python examples/simple_workflow.py

Use the graph in your own code:

from langchain_openai import ChatOpenAI

from seele_scholar_agent.graph import create_simple_writing_graph
from examples.common import build_initial_state, build_prompts

model = ChatOpenAI(model="gpt-4o-mini", api_key="sk-...")
state = build_initial_state("large language model interpretability")

app = create_simple_writing_graph(
    model=model,
    prompts=build_prompts(),
    rag_retriever=None,
)

result = await app.ainvoke(
    state,
    config={"configurable": {"thread_id": state["thread_id"]}},
)

Examples

Large runnable examples live in examples/:

File	Purpose
examples/common.py	Shared model, prompt, and initial-state helpers
examples/simple_workflow.py	Full automatic workflow with create_simple_writing_graph
examples/full_workflow_with_interrupts.py	Human-in-the-loop topic and outline approval
examples/custom_retrievers.py	Inject custom RAG and paper retrievers
examples/stream_nodes.py	Stream a single node with astream()
examples/figure_placeholders.py	Parse {{FIGURE: ...}} and {{TABLE: ...}} placeholders

Run any example from the repository root:

uv run python examples/full_workflow_with_interrupts.py

Core API

The package exposes two graph builders:

from seele_scholar_agent.graph import create_simple_writing_graph, create_writing_graph

• create_writing_graph(...): includes interrupts after topic proposal and outline planning.
• create_simple_writing_graph(...): runs without interrupts and is useful for tests or batch jobs.

Both require:

• model: a ChatOpenAI instance or compatible LangChain chat model.
• prompts: a complete PromptsConfig.
• rag_retriever: optional Callable[[str], Awaitable[list[DocumentChunk]]].

Optional paper sources can be injected with extra_paper_retrievers.

Workflow

START
  -> topic_proposer
  -> researcher
  -> planner
  -> writer <-> reviewer
  -> finalizer
  -> reference_generator
  -> consistency_checker
  -> END

create_writing_graph() interrupts after topic_proposer and planner so the caller can choose a topic and approve the outline.
