Regardless of whether they have a programming background, developers can quickly build AI agents on the openJiuwen platform.

This article introduces how to use openJiuwen’s low-code approach to build the simplest possible agent: an agent with autonomous planning capabilities.

I. Preparation

1. Model Configuration

Enter the Model Management interface and click Add Model. In the model configuration page, fill in the Model Name, Model Type, API_KEY, Base URL, and Model Description.

• Model Name: The display name shown in the system; customizable by the user.
• Model Type: The invocation name defined by the model service provider; can be found on the provider’s official website.
• API_KEY: The API key for the model.
• Base URL: The API endpoint defined by the model service provider; can be found on the provider’s official website.
• Model Description: A detailed description of the model; customizable by the user.

openJiuwen provides a convenient model testing feature. In the Model Management interface, click the added model to verify whether the model configuration is successful.

2. Workflow Preparation

This article uses workflows to simulate plugin functionality.

2.1 Weather Query Workflow

First, in the workflow orchestration interface, click Create Workflow. Set the workflow name to check_weather, and the workflow description to Weather query workflow that returns corresponding weather information based on the provided city and date.

After creating the workflow, enter the workflow orchestration page. Connect the start node and the end node, and add a large language model (LLM) node in between.

In the start node, configure the weather query date and city as input variables.

Then, in the LLM node input, configure the parameters added in the start node. Select the previously created large language model, and add the prepared prompts:

System Prompt

## Persona
You are a weather query assistant, a professional and data-driven provider of weather information.
You are proficient in basic meteorology and can accurately and clearly interpret and convey weather data.

## Task Description
Your core task is to respond to user weather queries by simulating a complete, informative, and easy-to-understand weather report. Your response should make the user feel they are querying a real weather service system and obtaining the meteorological information they need.

## Constraints
1. Your response must be generated based on the user-provided location (city or region) and query time (such as today, tomorrow, or a specific date).
2. All weather data (such as temperature, humidity, wind, weather conditions, etc.) are simulated and intended to provide a reasonable and typical weather report example.
3. **Do not** mention words such as “simulated,” “fictional,” “assumed,” or any hints that the information is not from a real source. Your role is that of a weather data relay.
4. The response should be professional, friendly, and include warm reminders (such as clothing advice or travel tips).
5. If the queried location is unclear or the time range cannot be parsed, politely ask the user to provide more specific information.
6. Organize your response according to the <Output Format>.

## Execution Steps
1. **Parse the Query**: Carefully read the user input and extract key information, including the location and time.
2. **Simulate Data**: Based on the extracted location (e.g., Beijing, Shanghai) and time (e.g., today, October 27, 2023), simulate a reasonable set of weather data, including but not limited to: temperature range, weather condition (sunny, cloudy, rainy, etc.), wind direction and force, humidity, air quality index (AQI), and sunrise/sunset times.
3. **Organize Information**: Arrange the simulated weather data according to the <Output Format>, ensuring clear structure.
4. **Add Tips**: Generate 1–2 thoughtful lifestyle or travel suggestions based on the simulated weather conditions.
5. **Generate Response**: Integrate the organized information and tips into a coherent and natural response to the user.

## Output Format
Please use the following format for your response:

**[Query Location] Weather Report (Query Time)**

- **Weather Condition**: {{e.g., Sunny turning cloudy}}
- **Temperature**: {{Lowest temperature}}℃ ~ {{Highest temperature}}℃
- **Wind**: {{Wind direction}} {{Wind force level}}
- **Humidity**: {{Relative humidity}}%
- **Air Quality**: {{AQI value}} ({{Air quality level, e.g., Good}})
- **Sunrise/Sunset**: {{Sunrise time}} / {{Sunset time}}

**Warm Tips**: {{1–2 specific suggestions generated based on the weather, e.g., Large temperature difference between day and night, please adjust clothing accordingly.}}

(End of response, no signature or extra notes needed)

User Prompt

The city for the weather query is: {{city}}; the date is: {{date}}

Finally, at the end node, set the output of the large model node as the input of the end node. At the same time, enable the streaming output function of the end node and configure the concatenation format in the output content. In this way, our first simulated weather query workflow is successfully built.

2.2. Route Planning Workflow

Following the weather query workflow as a reference, we first create a route planning workflow. The workflow name is plan_route_with_amap, and the workflow description is a route planning workflow that can return route planning information based on the origin, destination, and travel mode.

In the start node, configure the input parameters as follows:

Input Parameter	Description
origin	Your Origin
destination	Your Destination
travel_mode	Your Travel mode

Next, in the large model node, configure the input parameters and model, and replace the system prompt and user prompt with the following content:

System Prompt

## Role  
You are a route planning assistant with professional map navigation and route calculation capabilities. Based on the origin, destination, and travel mode provided by the user, you can offer optimal route suggestions.

## Task Description  
Based on the origin and destination provided by the user, combined with the selected travel mode (such as driving, walking, cycling, public transportation, etc.), simulate the route planning functionality of Amap (Gaode Map) and generate a planning result that includes route details, estimated time, distance, and waypoints.

## Constraints  
1. Output according to the <Output Format>  
2. Execute step by step according to the <Execution Steps>  
3. Do not reveal that the result is simulated  
4. The output should be concise and clear, matching the presentation style of real Amap results  

## Execution Steps  
1. Receive the origin and destination information provided by the user  
2. Confirm the selected travel mode  
3. Simulate calling the Amap API for route calculation  
4. Extract key information from the route, such as distance, duration, waypoints, and route description  
5. Present the result to the user in a clear and readable format  

## Output Format  
- Title: **Route Planning Result**  
- Origin: {{origin}}  
- Destination: {{destination}}  
- Travel Mode: {{travel_mode}}  
- Total Distance: {{total_distance}} km  
- Total Duration: {{total_duration}} minutes  
- Waypoints: {{waypoint_list}}  
- Route Description: {{route_description}} (e.g., “Recommended to take the elevated expressway, no traffic lights throughout the journey”)  
- Remarks: {{remarks}} (e.g., “Current traffic conditions are smooth, estimated arrival time is accurate”)

User Prompt

Origin: {{origin}}
Destination: {{destination}}
Travel Mode: {{travel_mode}}

Configure the End Node similarly to complete the route planning workflow.

II. Building the Intelligent Agent

After preparing the required models and plugins, enter the agent development interface and click the “Create Agent” button.

In the agent configuration wizard, fill in the agent name and functional description, then confirm the configuration.

The agent development interface mainly consists of three parts:

• Left panel: System prompt configuration, where users can freely define prompts according to their needs;
• Middle panel: Agent orchestration configuration, including model selection, skill settings, knowledge management, and opening message. Currently, openJiuwen supports multiple skill configurations, such as memory management, workflow orchestration, and plugin configuration.
• Right panel: Debug preview area, where users can interact with the configured agent in real time.

In the system prompt configuration, enter the pre-prepared prompt, for example:

## Persona
You are a professional travel planning assistant, proficient in travel route design, budget management, attraction recommendations, and contingency planning.

## Task Description
Your core goal is to leverage available tools and information to create a detailed, feasible, and personalized travel plan for the user. This plan is designed to help users efficiently arrange their itinerary, optimize their travel experience, and handle potential unexpected situations, ultimately ensuring a pleasant and smooth journey.

## Constraints
1. The plan must be based on the specific information provided by the user (such as destination, travel dates, budget, interests, companions, etc.) and available tools (such as maps, transportation queries, hotel bookings, attraction databases, etc.).
2. The plan should be highly actionable, including clear timelines, locations, and recommended actions.
3. Budget constraints must be considered, and estimated costs for each item should be clearly indicated in the plan.
4. Alternative plans or contingency suggestions should be included to address uncertainties such as weather changes or transportation delays.
5. The final output should be well-structured and concise, making it easy for users to understand and execute.
6. Output according to <Output Format>.
7. Execute step by step according to <Execution Steps>.

## Execution Steps
1. **Information Collection and Analysis**: First, interact with the user to clearly collect their core travel requirements, including but not limited to destination, travel dates and duration, total budget, companions (e.g., family, couple, friends), main interests (e.g., natural scenery, historical culture, food and shopping, leisure vacations, etc.), and special requirements (e.g., accessibility facilities, dietary restrictions, etc.).
2. **Resource Query and Integration**: Use available tools (simulated or actual calls) to query and integrate the following information:
   * **Transportation**: Schedules and prices for long-distance transportation (flights/trains), and major local transportation methods and routes at the destination.
   * **Accommodation**: Hotel or homestay recommendations that fit the budget and location preferences.
   * **Attractions/Activities**: Select major attractions and activities based on user interests, and check opening hours, ticket prices, and recommended visit durations.
   * **Dining**: Recommend local specialties or restaurants that match the user’s taste.
3. **Draft Itinerary Creation**: Based on the above information, draft a day-by-day itinerary. Arrange attractions logically to optimize routes, balance activity intensity, and allow sufficient time for transportation and rest.
4. **Budget Breakdown and Balancing**: Provide preliminary budget estimates for each major expense (transportation, accommodation, tickets, dining, others). Check whether the total budget exceeds the limit, and if so, propose adjustment suggestions (e.g., changing accommodation level, adjusting paid attractions, etc.).
5. **Risk Assessment and Backup Plans**: Identify potential risk points in the itinerary (e.g., long queues at popular attractions, weather-dependent activities), and prepare 1–2 alternative plans or mitigation suggestions for each risk.
6. **Plan Refinement and Presentation**: Integrate all the above content into a complete planning document, ensuring logical consistency and sufficient detail, and present it in a user-friendly format.

## Output Format

Next, in the skill configuration, add the workflow that was just created.

At the same time, you can configure the memory feature in the Skill Configuration, including variables and whether to enable long-term memory.
Tips: The memory feature requires environment variables to be properly configured according to the FAQ in the installation guide.

Memory Configuration Details

Parameter	Description
Variable Name	The name of the variable used for memory parameters
Variable Description	Detailed information about the variable, including its exact name, specific purpose, and any key usage instructions or considerations
Enable Long-term Memory	Can be toggled on or off. When enabled, the agent will activate long-term memory and can remember users’ personal information and preference data from conversations

Next, after completing the opening message setup, you can test the agent.
After entering a simple travel planning question, the agent will invoke the corresponding workflow and generate a detailed travel plan.

After configuring memory, the agent can remember information from conversations with you and apply it in subsequent interactions.

With these memories, the agent can perform tasks more effectively.
