What This Skill Does

This skill provides reusable implementation patterns extracted from better-chatbot for custom AI chatbot deployments. Use this skill to implement server action validators, tool abstraction systems, multi-AI provider support, and workflow execution in your own projects.

Core Capabilities

✅ Server action validators (auth + validation + FormData) ✅ Tool abstraction system (branded type tags) ✅ Multi-AI provider setup (OpenAI, Anthropic, Google, xAI, Groq) ✅ Zustand state management patterns ✅ Cross-field validation with Zod superRefine

---

Known Issues This Skill Prevents

Issue	Why It Happens	How Skill Fixes It
Inconsistent auth checks	Manual auth implementation	validatedActionWithUser pattern
Tool type mismatches	No runtime type checking	Branded type tags with .isMaybe()
State mutation bugs	Deep mutation of nested state	Shallow Zustand update pattern
Cross-field validation failures	Separate validators for related fields	Zod superRefine pattern
Provider configuration errors	Ad-hoc provider setup	Provider registry pattern

---

When to Use This Skill

✅ Use When:

• Building AI chatbot features in custom projects
• Implementing server action validators
• Creating tool abstraction layers
• Setting up multi-AI provider support
• Building workflow execution systems
• Adapting better-chatbot patterns to your project

###❌ Don't Use When:

• Contributing to better-chatbot itself (use better-chatbot skill instead)
• Need project-specific better-chatbot conventions
• Building non-chatbot applications

---

Quick Usage Example

// 1. Copy server action validators
// From templates/action-utils.ts to lib/action-utils.ts
// Adapt getUser() to your auth system (Better Auth, Clerk, Auth.js, etc.)

// 2. Use in your server actions
"use server"
import { validatedActionWithUser } from "@/lib/action-utils"
import { z } from "zod"

const schema = z.object({ name: z.string().min(1) })

export const updateProfile = validatedActionWithUser(
  schema,
  async (data, formData, user) => {
    // user is authenticated, data is validated
    await db.update(users).set(data).where(eq(users.id, user.id))
    return { success: true, data: { updated: true } }
  }
)

// 3. Copy other patterns as needed
// - Tool abstraction: templates/tool-tags.ts
// - AI providers: templates/providers.ts
// - State management: templates/workflow-store.ts

Result: Production-ready patterns with auth, validation, and type safety
