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-chatbotskill 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
