+# RAGFlow Admin Service & CLI
+
+### Introduction
+
+Admin Service is a dedicated management component designed to monitor, maintain, and administrate the RAGFlow system. It provides comprehensive tools for ensuring system stability, performing operational tasks, and managing users and permissions efficiently.
+
+The service offers real-time monitoring of critical components, including the RAGFlow server, Task Executor processes, and dependent services such as MySQL, Elasticsearch, Redis, and MinIO. It automatically checks their health status, resource usage, and uptime, and performs restarts in case of failures to minimize downtime.
+
+For user and system management, it supports listing, creating, modifying, and deleting users and their associated resources like knowledge bases and Agents.
+
+Built with scalability and reliability in mind, the Admin Service ensures smooth system operation and simplifies maintenance workflows.
+
+It consists of a server-side Service and a command-line client (CLI), both implemented in Python. User commands are parsed using the Lark parsing toolkit.
+
+- **Admin Service**: A backend service that interfaces with the RAGFlow system to execute administrative operations and monitor its status.
+- **Admin CLI**: A command-line interface that allows users to connect to the Admin Service and issue commands for system management.
+
+### Starting the Admin Service
+
+1.  Before start Admin Service, please make sure RAGFlow system is already started.
+
+2.  Run the service script:
+    ```bash
+    python admin/admin_server.py
+    ```
+    The service will start and listen for incoming connections from the CLI on the configured port.
+
+### Using the Admin CLI
+
+1.  Ensure the Admin Service is running.
+2.  Launch the CLI client:
+    ```bash
+    python admin/admin_client.py -h 0.0.0.0 -p 9381
+
+## Supported Commands
+
+Commands are case-insensitive and must be terminated with a semicolon (`;`).
+
+### Service Management Commands
+
+-   `LIST SERVICES;`
+    -   Lists all available services within the RAGFlow system.
+-   `SHOW SERVICE <id>;`
+    -   Shows detailed status information for the service identified by `<id>`.
+-   `STARTUP SERVICE <id>;`
+    -   Attempts to start the service identified by `<id>`.
+-   `SHUTDOWN SERVICE <id>;`
+    -   Attempts to gracefully shut down the service identified by `<id>`.
+-   `RESTART SERVICE <id>;`
+    -   Attempts to restart the service identified by `<id>`.
+
+### User Management Commands
+
+-   `LIST USERS;`
+    -   Lists all users known to the system.
+-   `SHOW USER '<username>';`
+    -   Shows details and permissions for the specified user. The username must be enclosed in single or double quotes.
+-   `DROP USER '<username>';`
+    -   Removes the specified user from the system. Use with caution.
+-   `ALTER USER PASSWORD '<username>' '<new_password>';`
+    -   Changes the password for the specified user.
+
+### Data and Agent Commands
+
+-   `LIST DATASETS OF '<username>';`
+    -   Lists the datasets associated with the specified user.
+-   `LIST AGENTS OF '<username>';`
+    -   Lists the agents associated with the specified user.
+
+### Meta-Commands
+
+Meta-commands are prefixed with a backslash (`\`).
+
+-   `\?` or `\help`
+    -   Shows help information for the available commands.
+-   `\q` or `\quit`
+    -   Exits the CLI application.
+

+        <p>
+            Welcome to our demo page! This page simulates a real website with content. 
+            Look for the floating chat button in the bottom-right corner - just like Intercom!
+        </p>
+        
+        <div class="feature-list">
+            <h3>🎯 Widget Features</h3>
+            <ul>
+                <li>Floating button that stays visible while scrolling</li>
+                <li>Click to open/close the chat window</li>
+                <li>Minimize button to collapse the chat</li>
+                <li>Professional Intercom-style design</li>
+                <li>Unread message indicator (red badge)</li>
+                <li>Transparent background integration</li>
+                <li>Responsive design for all screen sizes</li>
+            </ul>
+        </div>
+        
+        <p>
+            The chat widget is completely separate from your website's content and won't 
+            interfere with your existing layout or functionality. It's designed to be 
+            lightweight and performant.
+        </p>
+        
+        <p>
+            Try scrolling this page - notice how the chat button stays in position. 
+            Click it to start a conversation with our AI assistant!
+        </p>
+        
+        <div class="feature-list">
+            <h3>🔧 Implementation</h3>

+                <li>Simple iframe embed - just copy and paste</li>
+                <li>No JavaScript dependencies required</li>
+                <li>Works on any website or platform</li>
+                <li>Customizable appearance and behavior</li>

+        </div>
+        
+        <p>
+            This is just placeholder content to demonstrate how the widget integrates 
+            seamlessly with your existing website content. The widget floats above 
+            everything else without disrupting your user experience.

 ### Why does it take so long for my Agent to respond?
 
-An Agent’s response time generally depends on two key factors: the LLM’s capabilities and the prompt, the latter reflecting task complexity. When using an Agent, you should always balance task demands with the LLM’s ability. See [How to balance task complexity with an Agent's performance and speed?](#how-to-balance-task-complexity-with-an-agents-performance-and-speed) for details.
-
-## Best practices
-
-### How to balance task complexity with an Agent’s performance and speed?
-
-- For simple tasks, such as retrieval, rewriting, formatting, or structured data extraction, use concise prompts, remove planning or reasoning instructions, enforce output length limits, and select smaller or Turbo-class models. This significantly reduces latency and cost with minimal impact on quality.
-
-- For complex tasks, like multi-step reasoning, cross-document synthesis, or tool-based workflows, maintain or enhance prompts that include planning, reflection, and verification steps.
-
-- In multi-Agent orchestration systems, delegate simple subtasks to sub-Agents using smaller, faster models, and reserve more powerful models for the lead Agent to handle complexity and uncertainty.

+# 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.

+# Accelerate answering
+
+A checklist to speed up question answering.
+
+---
+
+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:
+
+## Balance task complexity with an Agent’s performance and speed?
+
+An Agent’s response time generally depends on many factors, e.g., the LLM’s capabilities and the prompt, the latter reflecting task complexity. When using an Agent, you should always balance task demands with the LLM’s ability. 
+
+- For simple tasks, such as retrieval, rewriting, formatting, or structured data extraction, use concise prompts, remove planning or reasoning instructions, enforce output length limits, and select smaller or Turbo-class models. This significantly reduces latency and cost with minimal impact on quality.
+
+- For complex tasks, like multi-step reasoning, cross-document synthesis, or tool-based workflows, maintain or enhance prompts that include planning, reflection, and verification steps.
+
+- In multi-Agent orchestration systems, delegate simple subtasks to sub-Agents using smaller, faster models, and reserve more powerful models for the lead Agent to handle complexity and uncertainty.
+
+:::tip KEY INSIGHT
+Focus on minimizing output tokens — through summarization, bullet points, or explicit length limits — as this has far greater impact on reducing latency than optimizing input size.
+:::
+
+## 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.
+
+:::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.

+## 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**

+# "Firecrawl plugin loaded successfully"
+# "Firecrawl data source registered"
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Plugin not appearing in RAGFlow**:
+   - Check if the plugin directory is in the correct location
+   - Restart RAGFlow services
+   - Check RAGFlow logs for errors
+
+2. **API Key Invalid**:
+   - Ensure your API key starts with `fc-`
+   - Verify the key is active in your Firecrawl dashboard
+   - Check for typos in the configuration
+
+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:
+# aiohttp>=3.8.0
+# pydantic>=2.0.0
+# requests>=2.28.0
+```
+
+## 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
