Vercel-Native Agent Hub (Demo 13) - Architecture Diagram

This diagram illustrates the complete flow of the Vercel-Native Agent Hub system, which orchestrates 15 specialized agents to build Vercel-native applications using a TDD workflow with quality gates.

System Overview

15 Total Agents: 1 PM Hub + 7 Core Advisors + 2 Optional Advisors + 5 Builders
Capability Scoping: Each agent has specific tool permissions (no dangerously-skip-permissions)
Quality Gates: Architect Gate, QA Gate, and GitOps verification
TDD Workflow: Tests are written first, then implementation, then verification

Agent Hub Flow Diagram

This diagram illustrates the multi-agent orchestration system from 12-agent-hub.ts.

Vercel AI Gateway OIDC Authentication Failure in Workflow DevKit

Executive Summary

When using the Vercel AI SDK with Workflow DevKit, AI Gateway authentication fails with GatewayAuthenticationError even when VERCEL_OIDC_TOKEN is present in the environment. The root cause is that the @vercel/oidc package requires Node.js fs module for token validation/refresh, which is not available in the workflow sandbox.

Environment

AI SDK Version: 6.0.50 (also tested with 5.0.76)
@ai-sdk/gateway: 3.0.23

Workflow v4.0.1-beta.49: Custom class serialization.

Pass an Order to start() - arrives as a real Order. Return an Order from a step - workflow receives it with all methods.

Your business logic stays in classes, not scattered across plain objects.

Custom Class Serialization in Workflow v4.0.1-beta.49

The Problem: Losing Your Domain Logic

Before Workflow v4.0.1-beta.49, building durable functions meant making a painful choice: either flatten your domain objects to plain JSON, or manually reconstruct them in every step.

Before: The Manual Approach ❌

Fast Key Repeat Settings for macOS

These settings make keys repeat much faster than the default System Preferences allows.

Current Settings

# Key repeat rate (lower = faster, default is 2)
defaults write NSGlobalDomain KeyRepeat -int 1
