└────────────────────────────┘ └───────────────────────────────┘Why not fully AI? While v0.dev generates components, you need React knowledge to connect them to your backend and handle state management.
Why not fully AI? Business logic and security require human oversight. AI can generate boilerplate but not secure authentication flows.
Why this mix? LangChain provides battle-tested patterns for AI orchestration that would take months to build from scratch.
Why not AI? Workflow orchestration needs reliability that AI can't provide. Temporal handles retries, failures, and state management deterministically.

# Use LangChain for structured output

class WorkflowSchema(BaseModel):
trigger: TriggerConfig
steps: List[StepConfig]
variables: Dict[str, str]POST /api/workflows/parseReasoning: LangChain's structured output ensures consistent parsing. Temporal handles the complex state management.
Reasoning: Starting with Google services provides immediate value and uses familiar APIs.
Reasoning: v0.dev accelerates UI development by 70% while maintaining custom control.
Instead of creating thousands of similar workflows, build a component-based system:
AVAILABLE_ACTIONS = {
"email_trigger": EmailTriggerAction,
"extract_data": AIExtractAction,
"save_to_drive": GoogleDriveSaveAction,
"save_to_dropbox": DropboxSaveAction,
"add_to_crm": CRMAddAction,
"send_notification": NotificationAction
} class BaseClientIntake:
core_steps = ["extract_client_data", "check_conflicts"]
class LawFirmIntake(BaseClientIntake):
additional_steps = ["create_matter", "send_retainer"]This solves the variation problem: 10 base templates + 50 actions = thousands of possible workflows without storing each one.
# Encrypted credential storage
class IntegrationCredential:
def __init__(self, service, credentials):
self.service = service
self.encrypted_creds = encrypt(credentials)
self.last_refreshed = datetime.now() async def email_trigger(user_id: str):
# Poll Gmail every 5 minutes
messages = await gmail_client.check_new_emails(
user_id=user_id,
query="subject:'New Client' is:unread"
)
return messages async def extract_client_info(email_body: str):
prompt = """Extract: client_name, email, phone, company
from this email: {email_body}"""
return await langchain_extract(prompt, email_body) async def create_client_folder(client_data: dict):
folder_name = f"{client_data['client_name']} - {date.today()}"
folder_id = await drive_client.create_folder(folder_name)
await drive_client.create_file(
f"{folder_name}/contact_info.json",
json.dumps(client_data)
)This gives you a working MVP in 20 days with one complete workflow, ready for beta testing.
