# Phase 2: Core Features
|
||||
**Duration:** 8 weeks
|
||||
**Team:** 1 Frontend Developer + 1 Agent Developer + 1 Backend Developer (part-time)
|
||||
**Goal:** Build missing launch blockers and essential features
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
Phase 2 focuses on implementing the core features needed for basic attended support sessions:
|
||||
- End-user portal for support code entry
|
||||
- One-time agent download mechanism
|
||||
- Complete input relay (mouse/keyboard)
|
||||
- Dashboard session management UI
|
||||
- Text clipboard synchronization
|
||||
- Remote PowerShell execution
|
||||
- Basic file download
|
||||
|
||||
**Completion Criteria:** MSP can generate support code, end user can connect, tech can view screen, control remotely, sync clipboard, run commands, and download files.
