# Final Fix: Cleaned Up Server Actions Loader ReferenceError: Agent is not defined

**Trigger**: Dev server crash on page reload (ReferenceError: Agent is not defined)
**Date**: 2026-07-23 09:11 WIB
**Affected files**:
- `src/lib/actions/agents.ts`
- `src/lib/actions/agentsCore.ts`
- 6 consumer components importing `Agent` type.

## Root Cause

Next.js Server Actions compiler processes any file containing "use server" at the top, and registers all of its exported identifiers as API action fetchers. When it sees `export { Agent }`, it tries to register `Agent` as a server action. Since `Agent` was a type interface in typescript, it did not exist as a real JavaScript value at runtime, leading to a `ReferenceError: Agent is not defined` or `Invalid Server Action Value` error.

## Solution

1. Removed the dummy `Agent` async function from `src/lib/actions/agentsCore.ts` entirely, reverting it to a clean TS type interface.
2. Removed all exports and imports of the `Agent` type/value in `src/lib/actions/agents.ts` (the "use server" actions bundle). This leaves `agents.ts` containing only actual, valid server action functions (`getAgents`, `getAgent`, etc.).
3. Redirected the `Agent` interface imports in all 6 customer files (components/views) to load directly from the non-server-action file @/lib/actions/agentsCore.
4. This completely separates runtime value-based mutating actions from TypeScript-only type exports, solving the Next.js Action Loader build error.
5. Checked that the project builds and runs cleanly with no errors.
