About

This Claude Skill provides Better-auth integration patterns for implementing authentication features like login, registration, and protected routes. It includes guarded queries/forms for protected endpoints and handles email verification requirements. Key principles include using `getRequestEvent()` for cookie access and placing redirects outside try/catch blocks since they throw errors.

Auth Patterns

Quick Pattern

// Login form
export const login = form(schema, async ({ email, password }) => {
	const event = getRequestEvent();
	await auth.api.signInEmail({
		body: { email, password },
		headers: event.request.headers,
	});
	redirect(303, '/dashboard'); // Outside try/catch
});

// Protected query
export const get_data = guarded_query(() => {
	return { message: 'Protected data' };
});

Core Principles

  • Use getRequestEvent() for headers (cookie access)
  • Redirect MUST be outside try/catch (throws error)
  • Use guarded_query/form/command for protected endpoints
  • Email verification required before login
  • Commands cannot redirect - use client-side goto()

sglang

Meta

SGLang is a high-performance LLM serving framework that specializes in fast, structured generation for JSON, regex, and agentic workflows using its RadixAttention prefix caching. It delivers significantly faster inference, especially for tasks with repeated prefixes, making it ideal for complex, structured outputs and multi-turn conversations. Choose SGLang over alternatives like vLLM when you need constrained decoding or are building applications with extensive prefix sharing.
