forge-ue5

An AI-powered debugging and architecture assistant for Unreal Engine 5 C++ developers.

Forge diagnoses crashes, reviews code, spots multiplayer security vulnerabilities, and guides architecture decisions — powered by 30 knowledge files covering the full UE5 C++ ecosystem.

> "Paste nothing. Forge reads it." > > With MCP active, Forge reads your Output Log, build errors, and C++ files directly from your editor. No copy-paste, no context switching.

• OOM-Safe crash & error diagnosis — Forge reads 5GB+ Output Logs using memory-safe streaming queues (zero RAM bloat), categorizes errors, and gives you the root cause in seconds
• Code review — safety, UE5 standards, performance, multiplayer security scan
• Architecture consulting — "where does this go?" with decision tables
• System analysis — paste multiple files, Forge analyzes them as a unified system
• Version migration warnings — tells you what breaks when upgrading UE versions
• Multiplayer security scan — unauthorized Server RPCs, unreplicated state, ownership issues
• Teaching mode — explains *why* a bug happened, not just the fix
• Session memory — remembers previously found issues across conversations
• Accessibility (VI) mode — full screen-reader support for visually impaired developers
