About this skill
Create Bubble Skill
Create a new Bubble integration for: $ARGUMENTS
Follow the CREATE_BUBBLE_README.md guide at packages/bubble-core/CREATE_BUBBLE_README.md exactly.
Step 1: Gather Requirements
Before writing any code, ask the user:
- Service name: What external service is this integrating with?
- Operations: What operations should this bubble support? (single or multiple)
- Authentication: What auth type? (
none,apikey,oauth,basic) - Credentials: What credential types are needed? (API key, access token, etc.)
Step 2: Create Folder Structure
All bubbles use this folder structure in packages/bubble-core/src/bubbles/service-bubble/{service-name}/:
{service-name}/
├── {service-name}.schema.ts # All Zod schemas
├── {service-name}.utils.ts # Utility functions (optional)
├── {service-name}.ts # Main bubble class
├── index.ts # Exports
├── {service-name}.test.ts # Unit tests
└── {service-name}.integration.flow.ts # Integration flow test
Step 3: Create Schema File ({service-name}.schema.ts)
Include:
- Parameter schema with
.describe()on ALL fields - Result schema with
successanderrorfields - Both INPUT and OUTPUT type exports
- Use
z.discriminatedUnion()for multi-operation bubbles - Use
z.transform()overz.preprocess()for type preservation - Always include
credentialsfield
Step 4: Create Main Bubble Class ({service-name}.ts)
Required static properties:
service,authType,bubbleName,type,schema,resultSchemashortDescription,longDescription,alias
Use INPUT type for generic constraint:
export class {ServiceName}Bubble<
T extends {ServiceName}ParamsInput = {ServiceName}ParamsInput,
> extends ServiceBubble<T, Extract<{ServiceName}Result, { operation: T['operation'] }>>
Implement:
constructorwith default valueschooseCredential()methodperformAction()method with operation switch
Step 5: Create Index File (index.ts)
Export the bubble class and types.
Step 6: Create Integration Flow Test ({service-name}.integration.flow.ts)
Integration flow tests are complete BubbleFlow workflows that exercise all bubble operations end-to-end.
Requirements:
- Exercise all or most operations of your bubble
- Include edge cases (special characters, spaces in names, unicode)
- Test null/undefined handling in data
- Return structured results tracking each operation's success/failure
- Use realistic data and scenarios
Template structure:
import { BubbleFlow, {ServiceName}Bubble, type WebhookEvent } from '@bubblelab/bubble-core';
export interface Output {
resourceId: string;
testResults: {
operation: string;
success: boolean;
details?: string;
}[];
}
export interface TestPayload extends WebhookEvent {
testName?: string;
}
export class {ServiceName}IntegrationTest extends BubbleFlow<'webhook/http'> {
async handle(payload: TestPayload): Promise<Output> {
const results: Output['testResults'] = [];
// 1. Test first operation
const result1 = await new {ServiceName}Bubble({
operation: 'operation_name',
// ... parameters with edge cases
}).action();
results.push({
operation: 'operation_name',
success: result1.success,
details: result1.success ? `Success details` : result1.error,
});
// 2. Test subsequent operations...
// Continue testing all operations
return {
resourceId: result1.data?.id || '',
testResults: results,
};
}
}

Quality Checklist
Before completing, ensure:
- ALL fields have
.describe()calls - Optional parameters have sensible defaults
- Input/output types are strictly typed with Zod
- Unit tests cover all operations
- Integration flow test exercises all operations end-to-end
- Error handling is consistent
- All 12 registration locations updated
Key Patterns to Follow
Type Safety:
- Use INPUT type (
z.input<>) for generic constraints and constructor - Use OUTPUT type (
z.output<>) for internal methods after validation - Cast
this.params as {ServiceName}ParamsinsideperformAction()
Schema Best Practices:
- Use
z.transform()to preserve input types in discriminated unions - Use
z.preprocess()only when accepting unknown/null/undefined inputs - All fields MUST have
.describe()calls - Provide sensible defaults with
.optional().default(value)
Error Handling:
- Return
{ success: false, error: message }format - Catch and wrap errors appropriately
Reference Implementations
Study these existing bubbles for patterns:
- Multi-operation:
packages/bubble-core/src/bubbles/service-bubble/google-sheets/ - Single operation:
packages/bubble-core/src/bubbles/service-bubble/ai-agent/ - Tool bubble:
packages/bubble-core/src/bubbles/tool-bubble/
When not to use it
- →Building UI-centric features
- →Non-standard integration patterns
Prerequisites
Limitations
- →Requires adherence to specific repo structure
- →Only sets up boilerplate, logic remains manual
How it compares
Enforces architectural consistency across all service integrations via code generation.
