AI agents are evolving fast, and one of the most exciting patterns emerging today is the sequential agent — an agent that performs tasks step‑by‑step, with each step feeding into the next. If you’ve ever wanted to build an AI workflow that behaves more like a human assistant—thinking, planning, and executing in order—this pattern is for you.
Project Structure
Github repository contains the following key files:
File | Purpose |
| Core sequential agent logic |
| Environment variables (API keys, etc.) |
The heart of the project is agent.py, where the agent is defined and configured.
Summary of the Program
1. Create an idea‑generation agent
LlmAgent whose job is to take a user’s topic and generate 3–5 creative content ideas, outputting only a numbered list.
2. Create a keyword‑research agent
LlmAgent that receives the generated content ideas and produces SEO keyword lists for each idea (primary + secondary keywords).
3. Chain the agents in order
A SequentialAgent is created, which runs the two agents step‑by‑step:
Idea generator
Keyword researcher
Each step receives the previous step’s output.
4. Pass shared state between agents
The first agent stores its output as content_ideas, and the second agent reads that value to produce seo_keywords_map.
5. Expose the full pipeline as the root agent
The content_creation_pipeline becomes the root_agent, meaning any user query triggers the entire workflow automatically.
