I built a multi-agent Deep Research workflow with LangGraph that turns a single topic into a fully cited research report—and then automatically publishes a LinkedIn post from it.

𝗔𝗴𝗲𝗻𝘁 𝟭
→ Analyzes the topic and plans the report structure.

𝗔𝗴𝗲𝗻𝘁 𝟮
→ Uses LangGraph's Send() API to spawn parallel workers—one for each section.

𝗔𝗴𝗲𝗻𝘁 𝟯
→ Collects and assembles every completed section.

𝗔𝗴𝗲𝗻𝘁 𝟰
→ Generates the introduction and conclusion after all research is finished.

🔍 𝗜𝗡𝗡𝗘𝗥 𝗚𝗥𝗔𝗣𝗛 (Runs in Parallel)

Every section gets its own research workflow.

𝗔𝗴𝗲𝗻𝘁 𝟱

• Generates 3 targeted search queries

• Searches the web using Tavily for fresh, relevant sources

• Writes the section with proper citations

━━━━━━━━━━━━━━━━━━

For a 6-section report, the workflow automatically coordinates:

✅ 1 Planning Agent

✅ 18 Parallel Worker Executions

✅ 1 Complete Research Report

━━━━━━━━━━━━━━━━━━

📄 𝗧𝗛𝗘 𝗢𝗨𝗧𝗣𝗨𝗧

A structured Markdown report where every section is grounded in real sources instead of relying on a single prompt.

But I wanted to take it one step further...

━━━━━━━━━━━━━━━━━━

✨ 𝗣𝗨𝗕𝗟𝗜𝗦𝗛𝗜𝗡𝗚 𝗔𝗚𝗘𝗡𝗧

Once the report is complete, another agent:

• Reads the entire report

• Extracts the most valuable insights

• Writes a LinkedIn post (hook, summary & hashtags)

• Publishes it directly to LinkedIn

𝗥𝗲𝘀𝗲𝗮𝗿𝗰𝗵 → 𝗥𝗲𝗽𝗼𝗿𝘁 → 𝗟𝗶𝗻𝗸𝗲𝗱𝗜𝗻

One automated workflow.

🤔 𝗪𝗛𝗬 𝗡𝗢𝗧 𝗝𝗨𝗦𝗧 𝗨𝗦𝗘 𝗔 𝗦𝗜𝗡𝗚𝗟𝗘 𝗟𝗟𝗠 𝗣𝗥𝗢𝗠𝗣𝗧?

✅ Every section performs its own focused web research.

✅ Research runs in parallel, making the workflow faster.

✅ Intro and conclusion are generated only after every section is complete.

✅ Every major claim is backed by cited sources.

✅ The final report is automatically transformed into a publish-ready LinkedIn post.

Python • LangGraph • LangChain • Tavily • FastAPI • Groq • Gemini • OpenAI

━━━━━━━━━━━━━━━━━━

My favorite part of LangGraph is the Send() API.

One node can fan out into N parallel subgraph executions without writing any threading or concurrency logic.

It's a clean and elegant pattern for building scalable AI workflows.

Next, I'm planning to extend this into a reusable research engine with support for different report types and publishing destinations.
