+# Execute SQL tool
+
+A tool that execute SQL queries on a specified relational database.
+
+---
+
+The **Execute SQL** tool enables you to connect to a relational database and run SQL queries, whether entered directly or generated by the system’s Text2SQL capability via an **Agent** component. 
+
+## Prerequisites
+
+- A database instance properly configured and running.
+- The database must be one of the following types:
+  - MySQL
+  - PostgreSQL
+  - MariaDB
+  - Microsoft SQL Server
+
+## Examples
+
+You can pair an **Agent** component with the **Execute SQL** tool, with the **Agent** generating SQL statements and the **Execute SQL** tool handling database connection and query execution. An example of this setup can be found in the **SQL Assistant** Agent template shown below:
+
+![](https://raw.githubusercontent.com/infiniflow/ragflow-docs/main/images/exeSQL.jpg)
+
+## Configurations
+
+### SQL statement
+
+This text input field allows you to write static SQL queries, such as `SELECT * FROM my_table`, and dynamic SQL queries using variables.
+
+:::tip NOTE
+Click **(x)** or type `/` to insert variables.
+:::
+
+For dynamic SQL queries, you can include variables in your SQL queries, such as `SELECT * FROM /sys.query`; if an **Agent** component is paired with the **Execute SQL** tool to generate SQL tasks (see the [Examples](#examples) section), you can directly insert that **Agent**'s output, `content`, into this field.
+
+### Database type
+
+The supported database type. Currently the following database types are available:
+
+- MySQL
+- PostreSQL
+- MariaDB
+- Microsoft SQL Server (Myssql)
+
+### Database
+
+Appears only when you select **Split** as method.
+
+### Username
+
+The username with access privileges to the database.
+
+### Host
+
+The IP address of the database server.
+
+### Port
+
+The port number on which the database server is listening.
+
+### Password
+
+The password for the database user.
+
+### Max records
+
+The maximum number of records returned by the SQL query to control response size and improve efficiency. Defaults to `1024`.
+
+### Output
+
+The **Execute SQL** tool provides two output variables:
+
+- `formalized_content`: A string. If you reference this variable in a **Message** component, the returned records are displayed as a table.
+- `json`: An object array. If you reference this variable in a **Message** component, the returned records will be presented as key-value pairs.

+
+## Disable Reasoning
+
+Disabling the **Reasoning** toggle will reduce the LLM's thinking time. For a model like Qwen3, you also need to add `/no_think` to the system prompt to disable reasoning.
+
+## Disable Rerank model
+
+- Leaving the **Rerank model** field empty (in the corresponding **Retrieval** component) will significantly decrease retrieval time.
+- When using a rerank model, ensure you have a GPU for acceleration; otherwise, the reranking process will be *prohibitively* slow.
+

+A checklist to speed up question answering for your chat assistant.

 Please note that some of your settings may consume a significant amount of time. If you often find that your question answering is time-consuming, here is a checklist to consider:
 
-- In the **Prompt engine** tab of your **Chat Configuration** dialogue, disabling **Multi-turn optimization** will reduce the time required to get an answer from the LLM.
-- In the **Prompt engine** tab of your **Chat Configuration** dialogue, leaving the **Rerank model** field empty will significantly decrease retrieval time.
+- Disabling **Multi-turn optimization** will reduce the time required to get an answer from the LLM.
+- Leaving the **Rerank model** field empty will significantly decrease retrieval time.
+- Disabling the **Reasoning** toggle will reduce the LLM's thinking time. For a model like Qwen3, you also need to add `/no_think` to the system prompt to disable reasoning.
 - When using a rerank model, ensure you have a GPU for acceleration; otherwise, the reranking process will be *prohibitively* slow.
 
 :::tip NOTE 
 Please note that rerank models are essential in certain scenarios. There is always a trade-off between speed and performance; you must weigh the pros against cons for your specific case.
 :::
 
-- In the **Assistant settings** tab of your **Chat Configuration** dialogue, disabling **Keyword analysis** will reduce the time to receive an answer from the LLM.

+## API Health Check
+
+In addition to checking the system dependencies from the **avatar > System** page in the UI, you can directly query the backend health check endpoint:
+
+```bash
+http://IP_OF_YOUR_MACHINE/v1/system/healthz
+```
+
+Here `<port>` refers to the actual port of your backend service (e.g., `7897`, `9222`, etc.).
+
+Key points:
+- **No login required** (no `@login_required` decorator)
+- Returns results in JSON format
+- If all dependencies are healthy → HTTP **200 OK**
+- If any dependency fails → HTTP **500 Internal Server Error**
+
+### Example 1: All services healthy (HTTP 200)
+
+```bash
+http://127.0.0.1/v1/system/healthz
+```
+
+Response:
+
+```http
+HTTP/1.1 200 OK
+Content-Type: application/json
+Content-Length: 120
+
+```
+
+Explanation:
+- Database (MySQL/Postgres), Redis, document engine (Elasticsearch/Infinity), and object storage (MinIO) are all healthy.
+- The `status` field returns `"ok"`.
+
+### Example 2: One service unhealthy (HTTP 500)

+
+Response:
+
+```http
+HTTP/1.1 500 INTERNAL SERVER ERROR

+Content-Length: 300
+
+```
+
+Explanation:
+- `redis` is marked as `"nok"`, with detailed error info under `_meta.redis.error`.
+- The overall `status` is `"nok"`, so the endpoint returns 500.

+
+## Verification
+
+### 1. Check Plugin Installation
+
+```bash
+# Check if the plugin directory exists
+ls -la /opt/ragflow/plugin/firecrawl/
+
+# Should show:
+# __init__.py
+# firecrawl_connector.py
+# firecrawl_config.py
+# firecrawl_processor.py
+# firecrawl_ui.py
+# ragflow_integration.py
+# requirements.txt
+```
+
+### 2. Test the Integration

+python example_usage.py
+```
+
+### 3. Check RAGFlow Logs
+
+```bash

+
+3. **Connection Timeout**:
+   - Increase the timeout value in configuration
+   - Check your network connection
+   - Verify the API URL is correct
+
+4. **Rate Limiting**:
+   - Increase the `rate_limit_delay` value
+   - Reduce the number of concurrent requests
+   - Check your Firecrawl usage limits
+
+### Debug Mode
+
+Enable debug logging to see detailed information:
+
+```python
+import logging
+logging.basicConfig(level=logging.DEBUG)
+```
+
+### Check Dependencies
+
+```bash
+# Verify all dependencies are installed
+pip list | grep -E "(aiohttp|pydantic|requests)"
+
+# Should show:

+```
+
+## Uninstallation
+
+To remove the plugin:
+
+1. **Remove plugin directory**:
+   ```bash
+   rm -rf /opt/ragflow/plugin/firecrawl/
+   ```
+
+2. **Restart RAGFlow**:
+   ```bash
+   docker compose -f /opt/ragflow/docker/docker-compose.yml restart
+   ```
+
+3. **Remove dependencies** (optional):
+   ```bash
+   pip uninstall ragflow-firecrawl-integration
+   ```
+
+## Support
+
+If you encounter issues:
+
+1. Check the [troubleshooting section](#troubleshooting)
+2. Review RAGFlow logs for error messages
+3. Verify your Firecrawl API key and configuration
+4. Check the [Firecrawl documentation](https://docs.firecrawl.dev)

+- `process_content(content)` - Process scraped content into RAGFlow document format
+- `process_batch(contents)` - Process multiple scraped contents
+- `chunk_content(document, chunk_size, chunk_overlap)` - Chunk document content for RAG processing
+
+## 🧪 **Testing**
+
+The integration includes comprehensive testing:
+
+```bash
+# Run the test suite
+cd intergrations/firecrawl
+python3 -c "
+import sys
+sys.path.append('.')
+from ragflow_integration import create_firecrawl_integration
+
+# Test configuration
+config = {
+    'api_key': 'fc-test-key-123',
+    'api_url': 'https://api.firecrawl.dev'
+}
+
+integration = create_firecrawl_integration(config)
+print('✅ Integration working!')
+"
+```
+
+## 🐛 **Error Handling**
+
+The integration includes robust error handling for:
+
+- **Rate Limiting** - Automatic retry with exponential backoff
+- **Network Issues** - Retry logic with configurable timeouts
+- **Malformed Content** - Content validation and cleaning
+- **API Errors** - Detailed error messages and logging
+
+## 🔒 **Security**
+
+- API key validation and secure storage
+- Input sanitization and validation
+- Rate limiting to prevent abuse
+- Error handling without exposing sensitive information
+
+## 📈 **Performance**
+
+- Concurrent request processing
+- Configurable timeouts and retries
+- Efficient content processing
+- Memory-conscious document handling
