# How to add prompts from the prompt library to your apps & agents
### **1. Adding a prompt to an app**
This is part of the broader process of creating an app using a knowledge base. To understand the complete app creation flow, refer to the [app creation guide](https://docs.zbrain.ai/zbrain-documentation/zbrain-builder/app/how-to-create-a-new-app).
To add a prompt from the prompt library during app setup:
* Click on the ‘Apps’ tab in the ZBrain Builder interface.
* Select the ‘+ Create’ button and enter all the details of the app in the ‘App Details’ section. Click ‘Next’.
* Go to 'Configure Bot'.
* In the ‘System Instructions’ section, click ‘Library’.
* Select ‘Add from Prompt Library’, and choose the prompt template you want.
* Optionally, check ‘Import Prompt Settings’ to carry over the prompt’s model, temperature, top‑p, max tokens, etc and then click ‘Use’.
This method reuses existing prompts, keeping consistency and saving setup time.
### **2. Adding a prompt to an agent**
This is one segment of the comprehensive agent creation process. To understand the entire workflow, please refer to [Creating custom AI agents | ZBrain Documentation](https://docs.zbrain.ai/zbrain-documentation/zbrain-builder/zbrain-ai-agents/creating-custom-ai-agents).
To use a prompt from the prompt library while defining an agent’s flow:
* From the ZBrain Builder, go to the ‘Agents’ tab and start creating a new agent.
* After filling out the required details, proceed to the 'Define Flow' step.
* Inside the visual flow builder, click on the ‘+’ button to add a new tool/action in the sequence.
* Search for ZBrain and select ‘Ask AI Model’ from the list of available actions.
* In the side panel that appears, configure the model, input variables, and other options as needed.
* Under the ‘Prompt Library’ dropdown, select the prompt template you want to use.
This inserts a predefined prompt into your agent’s logic without writing it from scratch.
The rest of the steps for agent setup, like connecting outputs, configuring inputs, and managing access, remain the same.
### **Benefits of using the prompt library**
| Benefit | Description |
| ------------------ | ---------------------------------------------------------------------------- |
| Standardized reuse | Maintain consistency by using the same prompts in different apps and agents. |
| Reduces errors | Using pre-tested prompts lowers the chances of logic or formatting issues. |
| Faster setup | Avoid rebuilding prompts, select and plug them in. |
