# What does this PR do? ReAct prompting attempts to use the Thinking, Action, Observation loop to improve the model's reasoning ability via prompt engineering. With this PR, it now supports the various features in Streamlit's playground: 1. Adding the selection box for choosing between Agent Type: normal, ReAct. 2. Adding the Thinking, Action, Observation loop streamlit logic for ReAct agent, as seen in many LLM clients. 3. Improving tool calling accuracies via ReAct prompting, e.g. using web_search. **Folded**  **Collapsed**  [//]: # (If resolving an issue, uncomment and update the line below) [//]: # (Closes #[issue-number]) ## Test Plan [Describe the tests you ran to verify your changes with result summaries. *Provide clear instructions so the plan can be easily re-executed.*] Run the playground and uses reasoning prompts to see for yourself. Steps to test the ReAct agent mode: 1. Setup a llama-stack server as [getting_started](https://llama-stack.readthedocs.io/en/latest/getting_started/index.html) describes. 2. Setup your Web Search API keys under `llama_stack/distribution/ui/modules/api.py`. 3. Run the streamlit playground and try ReAct agent, possibly with `websearch`, with the command: `streamlit run llama_stack/distribution/ui/app.py`. ## Test Process Current results are demonstrated with `llama-3.2-3b-instruct`. Results will vary with different models. You should be seeing clear distinction with normal agent and ReAct agent. Example prompts listed below: 1. Aside from the Apple Remote, what other devices can control the program Apple Remote was originally designed to interact with? 2. What is the elevation range for the area that the eastern sector of the Colorado orogeny extends into? ## Example Test Results **Web search on AppleTV** <img width="1440" alt="normal_output_appletv" src="https://github.com/user-attachments/assets/bf6b3273-1c94-4976-8b4a-b2d82fe41330" /> <img width="1440" alt="react_output_appletv" src="https://github.com/user-attachments/assets/687f1feb-88f4-4d32-93d5-5013d0d5fe25" /> **Web search on Colorado** <img width="1440" alt="normal_output_colorado" src="https://github.com/user-attachments/assets/10bd3ad4-f2ad-466d-9ce0-c66fccee40c1" /> <img width="1440" alt="react_output_colorado" src="https://github.com/user-attachments/assets/39cfd82d-2be9-4e2f-9f90-a2c4840185f7" /> **Web search tool + MCP Slack server** <img width="1250" alt="normal_output_search_slack png" src="https://github.com/user-attachments/assets/72e88125-cdbf-4a90-bcb9-ab412c51d62d" /> <img width="1217" alt="react_output_search_slack" src="https://github.com/user-attachments/assets/8ae04efb-a4fd-49f6-9465-37dbecb6b73e" />  |
