Overview

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.

Why Use This Skill

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 appId and version, making it easy to iterate on applications without manual version management.

• Instant 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.

Important: Long-Running Task

This API call is a long-running operation. The Vibe Dev Flow performs multiple steps including workspace creation, AI code generation, building, and publishing.

• Expected duration: Typically 2-5 minutes, but complex apps may take longer
• Timeout threshold: Do NOT time out the request unless it exceeds 10 minutes
• SSE streaming: The connection stays open throughout the process. Even if no SSE messages are received for a period, the request is NOT stalled or stuck as long as the connection remains open. Wait for the stream to end or the 10-minute timeout.
• Token efficiency: Agents should use "streamUpdatePolicy": "artifactOnly" in the request body to receive only the final artifact output, significantly reducing input tokens. But it won't count as being stuck if no messages are received for a while.

When to Use This Skill

Use this skill when the user wants to:

• Create a new Pulse App from a description or prompt
• Update an existing Pulse App with new features
• Generate code for a Pulse Editor application
• Build and publish a Pulse App

API Authentication

The Pulse Editor API requires an API key for authentication. Users can obtain their API key by:

1. Signing up or logging in at https://pulse-editor.com/
2. Going to the developer section under account settings
3. Requesting beta access at https://pulse-editor.com/beta (if needed)
4. Creating and copying the API key from the developer section

The API key should be passed in the Authorization header as a Bearer token:

Authorization: Bearer your_api_key_here

API Endpoint

POST https://pulse-editor.com/api/server-function/vibe_dev_flow/latest/generate-code/v2/generate

Request Headers

Header	Required	Description
Authorization	Yes	Bearer token with Pulse Editor API key
Content-Type	Yes	application/json
Accept	Yes	text/event-stream

Request Body Parameters

Parameter	Type	Required	Description	Example
prompt	string	Yes	The user prompt instructing the Vibe coding agent	"Create a todo app with auth and dark mode"
appName	string	No	Friendly display name for the app	"My Todo App"
appId	string	No	Unique identifier of an existing app to update. If not provided, a new app will be created	"my_app_x7k9q2"
version	string	No	Version identifier of an existing app. If not provided, defaults to latest version	"0.0.1"
streamUpdatePolicy	string	No	Set to "artifactOnly" to receive only the final artifact output (recommended for agents to save tokens)	"artifactOnly"

Response

The response is a Server-Sent Events (SSE) stream. Each event contains a JSON-encoded message. Messages are separated by \n\n.

Each SSE message is formatted as:

data: <JSON>

followed by a blank line.

Message Types

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
}

Data Types

Type	Description
text	Text output from the agent
toolCall	Tool invocation by the agent
toolResult	Result from a tool execution
artifactOutput	Final artifact with published app info

Artifact Output Format

When the generation completes, an artifactOutput message contains:

{
  "publishedAppLink": "https://pulse-editor.com/app/...",
  "sourceCodeArchiveLink": "https://...",
  "appId": "my_app_x7k9q2",
  "version": "0.0.1"
}

Response Status Codes

Code	Description
200	Streaming SSE with progress and final result
400	Bad request - invalid parameters
401	Unauthorized - invalid or missing API key
500	Server error

  -H 'Content-Type: application/json' \
  -H 'Accept: text/event-stream' \
  -H 'Authorization: Bearer your_api_key_here' \
  -d '{

Python Example

import requests
import json

url = "https://pulse-editor.com/api/server-function/vibe_dev_flow/latest/generate-code/v2/generate"

headers = {
    "Authorization": "Bearer your_api_key_here",
    "Content-Type": "application/json",
    "Accept": "text/event-stream"
}

payload = {
    "prompt": "Create a todo app with auth and dark mode",
    "appName": "My Todo App"
}

response = requests.post(url, json=payload, headers=headers, stream=True)

messages = {}  # Track messages by messageId
buffer = ""

for chunk in response.iter_content(chunk_size=None, decode_unicode=True):
    buffer += chunk

    # SSE messages end with \n\n
    while "\n\n" in buffer:
        part, buffer = buffer.split("\n\n", 1)

        if not part.startswith("data:"):
            continue

        data = json.loads(part.replace("data: ", "", 1))

        if data["type"] == "creation":
            messages[data["messageId"]] = data
            print(f"New: {data['data'].get('result', '')}")

        elif data["type"] == "update":
            msg = messages.get(data["messageId"])
            if msg:
                msg["data"]["result"] = (msg["data"].get("result") or "") + (data["delta"].get("result") or "")
                msg["isFinal"] = data["isFinal"]

        # Check for artifact output
        if data.get("data", {}).get("type") == "artifactOutput" and data.get("isFinal"):
            result = json.loads(messages[data["messageId"]]["data"]["result"])
            print(f"Published: {result.get('publishedAppLink')}")

let buffer = "";
const messages = new Map();

while (true) {

  buffer += decoder.decode(value, { stream: true });

  // SSE messages end with \n\n
  const parts = buffer.split("\n\n");
  buffer = parts.pop(); // Keep incomplete part in buffer

  for (const part of parts) {

    const json = part.replace(/^data:\s*/, "");
    const message = JSON.parse(json);

    if (message.type === "creation") {
      messages.set(message.
