These operations will show clear warning about permanent deletion.

Response Formatting

Present app data in clear, user-friendly formats:

For app lists: Display as a table with ID, name, description, and published status For app details: Show complete configuration including components, queries, and actions For publish/unpublish: Confirm the deployment status change For errors: Provide clear, actionable error messages

Common User Requests

"Show me all apps"

pup app-builder list

"Get details for app abc-123"

pup app-builder get abc-123

"Publish my incident response app"

First find the app:

pup app-builder list --query="incident"

Then publish it:

pup app-builder publish <app-id>

"Delete app abc-123"

pup app-builder delete abc-123

App Builder Concepts

Components

UI elements that users interact with:

• Input Components: Text input, dropdown, date picker, file upload
• Display Components: Tables, charts, text, images, metrics
• Action Components: Buttons, forms, modals
• Layout Components: Containers, tabs, sections

Queries

Data sources that populate your app:

• Datadog APIs: Metrics, logs, traces, events
• External APIs: HTTP requests to third-party services
• Workflow Actions: Execute Datadog Workflow Automation actions
• Custom JavaScript: Process and transform data

Actions

Operations triggered by user interactions:

• Query Execution: Fetch data on demand
• State Updates: Modify app state
• Navigation: Move between app views
• External Calls: Trigger webhooks or APIs

JavaScript Expressions

Custom logic using JavaScript:

• Reference component values: ${textInput1.value}
• Transform data: ${query1.data.map(x => x.value)}
• Conditional logic: ${metric.value > threshold ? "alert" : "ok"}
• Custom functions: Execute JavaScript for complex operations

Error Handling

Common Errors and Solutions

Missing Credentials:

Error: DD_API_KEY environment variable is required

→ Tell user to set environment variables

App Not Found:

Error: App not found: app-123

→ Verify the app ID exists using app-builder list

Permission Error:

Error: Insufficient permissions or app key not registered

→ Check that API/App keys have Actions API access and are properly registered

Invalid Configuration:

Error: Invalid app configuration

→ Validate app JSON structure and required fields

Publish Error:

Error: Cannot publish app with validation errors

→ Review app configuration for missing components or queries

App Key Registration Required:

Error: This API requires a registered application key

→ Guide user to register their app key: https://docs.datadoghq.com/api/latest/action-connection/#register-a-new-app-key

Best Practices

1. Start Simple: Begin with basic components and queries, then enhance
2. Test Before Publishing: Always test apps thoroughly before publishing
3. Use Queries Wisely: Cache query results when possible to improve performance
4. Error Handling: Add proper error messages for failed queries
5. Permissions: Ensure app keys have appropriate scopes for required APIs
6. Documentation: Document app purpose, components, and data sources
7. Version Control: Export and store app configurations for backup

Examples of Good Responses

When user asks "Show me all apps":

I'll list all App Builder applications in your Datadog organization.

<Execute app-builder list command>

Found 5 apps:

| ID | Name | Description | Published |
|----|------|-------------|-----------|
| app-123 | Incident Response | Manage incidents | Yes |
| app-456 | Service Health | Monitor services | Yes |
| app-789 | Custom Metrics | Track custom metrics | No |
| app-abc | Cost Analysis | Analyze cloud costs | Yes |
| app-def | User Dashboard | User analytics | No |

Summary:
- 3 published apps
- 2 draft apps
- All apps are using Actions API

Would you like details on any specific app?

When user asks "Publish my incident response app":

I'll publish the incident response app.

First, let me find it:
<Execute app-builder list with query>

Found: App app-123 "Incident Response Dashboard"

⚠️ Publishing this app will:
1. Make it available to all users in your organization
2. Enable the app URL for embedding and sharing
3. Execute all configured queries and actions

The app includes:
- 5 components (table, button, modal, chart, text)
- 3 queries (list-incidents, get-metrics, create-incident)
- 2 actions (create-incident, assign-incident)

<After user confirms, execute publish command>

App app-123 "Incident Response Dashboard" has been published successfully.
App URL: https://app.datadoghq.com/app/app-123

The app is now available to your team.

When user asks to create an app:

I can help you create an App Builder application. App creation requires structured configuration including:

1. **Basic Information**:
   - Name: Descriptive app name
   - Description: App purpose and functionality

2. **Components**: UI elements users interact with
   - Input components (text, dropdown, date picker)
   - Display components (table, chart, text)
   - Action components (buttons, forms)

3. **Queries**: Data sources for your app
   - Datadog APIs (metrics, logs, traces)
   - External HTTP APIs
   - Workflow actions

4. **Actions**: Operations triggered by interactions
   - Query execution
   - State updates
   - External API calls

I recommend two approaches:

**Approach 1: Start in the UI**
1. Create a basic app in the Datadog UI (drag-and-drop interface)
2. Export or retrieve it using this tool
3. Modify as needed programmatically

**Approach 2: Provide Configuration**
Share the app configuration JSON, and I'll create it for you.

Which approach would you prefer?

When user asks to delete an app:

⚠️ WARNING: You're about to delete app app-123 "Incident Response Dashboard".

This action will:
- Permanently remove the app
- Delete all 5 components and their configurations
- Remove all queries and actions
- Unpublish the app if currently published
- Break any embedded instances or shared links

This cannot be undone.

<If user confirms, execute delete command>

App app-123 has been deleted successfully.
