This skill enables you to interact with the Pulse Editor Vibe Dev Flow API to generate, build, and publish Pulse Apps using cloud-based AI coding agents. The API uses Server-Sent Events (SSE) streaming to provide real-time progress updates.
This skill provides significant advantages for AI agents:
No Local Code Generation Required: Instead of generating code locally on the user's machine, agents can offload code generation to Pulse Editor's cloud-based vibe coding service. This eliminates the need for local build tools, dependencies, or development environments.
Built-in Version Control: Every app generation is automatically versioned. Agents can update existing apps by specifying
appIdversionInstant Deployment: Apps are automatically built and published immediately after generation. No separate build or deploy steps needed—users get a live, working app URL as soon as generation completes.
Parallel App Generation: Agents can generate multiple apps simultaneously by making concurrent API calls. This is ideal for scenarios where an agent needs to scaffold several microservices, create multiple related applications, or batch-generate apps for different purposes—all at the same time.
Stateless & Scalable: Since all code generation happens in the cloud, agents remain lightweight and can scale horizontally without worrying about local resource constraints.
This API call is a long-running operation. The Vibe Dev Flow performs multiple steps including workspace creation, AI code generation, building, and publishing.

The Pulse Editor API requires an API key for authentication. Users can obtain their API key by:
The API key should be passed in the
AuthorizationAuthorization: Bearer your_api_key_here
POST

|---|---|---|
| Yes | Bearer token with Pulse Editor API key |
| Yes | |
| Yes | |
| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| string | Yes | The user prompt instructing the Vibe coding agent | |
| string | No | Friendly display name for the app | |
| string | No | Unique identifier of an existing app to update. If not provided, a new app will be created | |
| string | No | Version identifier of an existing app. If not provided, defaults to latest version | |
| string | No | Set to | |
The response is a Server-Sent Events (SSE) stream. Each event contains a JSON-encoded message. Messages are separated by
\n\nEach SSE message is formatted as:
data: <JSON>
followed by a blank line.
There are two message types:
Creation Message - A new message in the stream:
{ "messageId": "msg_abc123", "type": "creation", "data": { "type": "text" | "toolCall" | "toolResult" | "artifactOutput", "result": "string content", "error": "error message if any" }, "isFinal": false }
Update Message - Delta update to an existing message:
{ "messageId": "msg_abc123", "type": "update", "delta": { "result": "additional content to append", "error": "additional error to append" }, "isFinal": true }
| Type | Description |
|---|---|
| Text output from the agent |
| Tool invocation by the agent |
| Result from a tool execution |
| Final artifact with published app info |
When the generation completes, an
artifactOutput{ "publishedAppLink": "https://pulse-editor.com/app/...", "sourceCodeArchiveLink": "https://...", "appId": "my_app_x7k9q2", "version": "0.0.1" }

|---|---|
| 200 | Streaming SSE with progress and final result |
| 400 | Bad request - invalid parameters |
| 401 | Unauthorized - invalid or missing API key |
