+# DeepAgents — RAGFlow knowledge Q&A template
+
+Scaffolds a DeepAgents knowledge-base application that connects to a
+user-provided RAGFlow endpoint. Retrieval is dataset-scoped; document upload
+and asynchronous parsing require an explicit LangGraph interrupt approval.
+
+## Inputs
+
+| Variable | Description | Default |
+| --- | --- | --- |
+| `project_name` | Human-readable project name. | `RAGFlow Knowledge QA DeepAgent` |
+| `project_slug` | Generated Python package and directory name. | Derived from `project_name` |
+| `author` | Project author. | `Your Name` |
+| `system_prompt` | Safety and response-language instructions. | RAGFlow Q&A prompt |
+| `default_model` | OpenAI-compatible model id. | Empty; configure at runtime |
+| `langgraph_port` | Local LangGraph port. | `2024` |
+| `frontend_port` | Local Vite port. | `5174` |
+
+Runtime-only RAGFlow credentials, model credentials, upload-root location, and
+LangSmith settings live in the generated `.env.example`.

+## Contributor notes
+
+- The template pins `ragflow-sdk==0.26.4`, which requires Python 3.13.
+- The browser never receives the RAGFlow API key.
+- Mutation tools are root-agent-only; delegated knowledge research is
+  read-only.
+- ContextSeek and browser file ingress are intentionally deferred.

+
+DeepAgents knowledge-base Q&A backed by a user-provided RAGFlow service. The
+LangGraph backend can list datasets, retrieve scoped chunks, and request human
+approval before uploading or parsing documents. The React frontend streams
+messages, tool calls, todos, and approval prompts.
+
+## Prerequisites
+
+- Python 3.13, `uv`, Node.js, and npm.
+- A running RAGFlow service and API key. Configuring RAGFlow with
+  `DOC_ENGINE=seekdb` is the recommended deployment.
+- An OpenAI-compatible model and API key for the DeepAgents orchestrator.
+
+## Quickstart
+
+```bash
+cp .env.example .env
+cp frontend/.env.example frontend/.env
+$EDITOR .env
+
+agentseek task sync
+agentseek task frontend
+agentseek info
+agentseek doctor
+agentseek dev --dry-run
+agentseek dev
+```
+
+The backend defaults to `http://127.0.0.1:{{ cookiecutter.langgraph_port }}` and
+the frontend to `http://127.0.0.1:{{ cookiecutter.frontend_port }}`. For remote
+development, set `LANGGRAPH_HOST=0.0.0.0 FRONTEND_HOST=0.0.0.0` only on a
+trusted network. Set `VITE_LANGGRAPH_API_URL` when the browser cannot reach the
+backend through the page hostname.
+
+```bash
+LANGGRAPH_HOST=0.0.0.0 FRONTEND_HOST=0.0.0.0 agentseek dev
+```
+
+## Configuration
+
+`AGENTSEEK_MODEL`, `AGENTSEEK_API_KEY`, and optional `AGENTSEEK_API_BASE`
+configure the DeepAgents model. They are independent of the models configured
+inside RAGFlow.
+
+`RAGFLOW_BASE_URL` and `RAGFLOW_API_KEY` connect to RAGFlow.
+`RAGFLOW_UPLOAD_ROOT` is the only server-local directory from which the agent
+may read upload candidates. Browser file upload is not included.
+
+## Knowledge ingestion
+
+The generated project includes `uploads/sample-policy.md`. Ask the agent to
+upload that relative filename to an explicit dataset ID. The agent pauses
+before calling RAGFlow and displays the dataset and filename. Approve or cancel
+in the UI. Parsing uses the same approval flow and starts asynchronously.
+
+Try retrieval with:
+
+```text
+List my RAGFlow datasets. Then search dataset <dataset-id> for the deployment policy.
+```
+
+Retrieved chunks are treated as untrusted data rather than agent instructions.
+Dataset IDs are always explicit; the agent never searches every visible
+dataset by default.
+
+## Observability
+
+Set `LANGSMITH_TRACING=true`, `LANGSMITH_API_KEY`, and optionally
+`LANGSMITH_PROJECT` to send traces to LangSmith. No other observability backend
+is configured.
+
+## Deferred capabilities
+
+ContextSeek is not included in this version. End-user authentication,
+browser-based file upload, and interrupt-edit-resume of retrieval strategies
+are also outside the template scope. RAGFlow access is limited by the single
+configured API key.
+
+## Deviations from the template contract
+
+The generated project requires Python `>=3.13,<3.14` because
+`ragflow-sdk==0.26.4` declares that interpreter range. The focused template
+tests verify the pinned SDK surface used by the adapter.
