description	Create new server actions following Memescope Monday patterns. Use when: adding data mutations, server-side fetches, authenticated operations, or new app/actions/ files. Handles session checks, Drizzle queries, revalidation, and error returns.
argument-hint	Describe the server action (e.g., 'toggle bookmark on a project')

Server Action

Create server actions in app/actions/ following project conventions.

When to Use

• Adding a new data mutation (insert, update, delete)
• Creating a server-side fetch for a page or component
• Any authenticated operation that reads/writes to the database

Procedure

1. Create or edit a file in app/actions/ with the "use server" directive at the top
2. Use the standard session helper pattern
3. Add Drizzle ORM queries (never raw SQL)
4. Return typed results or error objects
5. Call revalidatePath() after mutations

Template

"use server"

import { revalidatePath } from "next/cache"
import { headers } from "next/headers"
import { db } from "@/drizzle/db"
import { project } from "@/drizzle/db/schema"
import { auth } from "@/lib/auth"
import { and, eq, desc } from "drizzle-orm"

async function getSession() {
  return auth.api.getSession({ headers: await headers() })
}

export async function myAction(input: string) {
  const session = await getSession()
  if (!session?.user?.id) return { error: "Not authenticated" }

  // Drizzle query
  const result = await db
    .select()
    .from(project)
    .where(eq(project.id, input))

  revalidatePath("/relevant-path")
  return { data: result }
}

Rules

• Always start with "use server" directive
• Always check session?.user?.id for auth-required actions
• Return { error: string } for failures, not thrown exceptions
• Return empty arrays [] for unauthenticated read operations
• Use Drizzle query builder — never raw SQL
• Import from drizzle-orm for operators: eq, and, or, desc, count, sql, etc.
• Import schema tables from @/drizzle/db/schema
• Call revalidatePath() after any write mutation
• Use constants from @/lib/constants for limits and settings
• Enums are string literals (e.g., eq(project.chain, "solana"))
