| 3 | ## Workflow |
| 4 | |
| 5 | ### 1. Fetch the Documentation Index |
| 6 | |
| 7 | Use `fetch_url` to read: https://docs.langchain.com/llms.txt |
| 8 | |
| 9 | This returns a structured list of all available documentation with descriptions. |
| 10 | |
| 11 | ### 2. Select Relevant Documentation |
| 12 | |
| 13 | Identify 2-4 most relevant URLs from the index. Prioritize: |
| 14 | - **Implementation questions** — specific how-to guides |
| 15 | - **Conceptual questions** — core concept pages |
| 16 | - **End-to-end examples** — tutorials |
| 17 | - **API details** — reference docs |
| 18 | |
| 19 | ### 3. Fetch and Apply |
| 20 | |
| 21 | Use `fetch_url` on the selected URLs, then complete the user's request using the documentation content. |
| 22 | |
| 23 | If `fetch_url` fails or returns empty content, retry once. If it fails again, inform the user and suggest checking https://langchain-ai.github.io/langgraph/ directly. |
