dsh-godot-preview

If you build Godot 4 projects inside DeepSeek Harness Desktop, the biggest friction in the loop is rarely writing code-it is seeing the result: jump to a browser, wait for an export, jump back. dsh-godot-preview removes that context switch by embedding a Godot Preview view right in the Harness conversation pane, so you can verify logic, tweak UI, or watch a live scene without ever leaving the chat surface. The plugin relies entirely on a Godot 4 executable you have already installed and the project.godot file at your active session workspace root; it never downloads, installs, or bundles the engine or any additional runtimes.

The core experience is built around speed and resilience. In Web mode it performs a Web Debug export and serves the loopback build inside Harness, coalescing rapid file changes through configurable debounce and single-flight rebuilds into at most one queued build. In Native mode it launches a managed Godot window with idempotent stop semantics. Whichever mode you use, the last successful preview is preserved when a later export fails, and logs plus structured error locations are bounded so the signal stays readable. Every spawned process uses shell:false, a minimal environment allowlist, and canonical-path containment, keeping the attack surface strictly to localhost.

This plugin is ideal for solo developers or small teams who maintain Godot 4 projects as part of a daily Harness workflow, particularly those targeting portable Web previews with GDScript and the Compatibility renderer. All you need is a Godot 4.x binary on your machine and an export preset named Web; the plugin handles the rest.
