This release adds three new skill modules targeting the areas where agents fail most: GDExtension (native C++/Rust bindings), multithreading (WorkerThreadPool, thread safety rules, deferred calls), and mobile development (Android/iOS export, permissions, JavaClassWrapper version gates). The catalog grows from 45 to 48 skills, all authored against official Godot docs and kept under a 16 KB token budget. A new Native & Performance category is added, and all skills are wired into the cross-reference graph. ## Content If you've used Claude Code, Cursor, Copilot, or Gemini CLI on a Godot 4 project, you've seen it: the agent confidently writes Godot 3 syntax, invents an API that never existed, or hand-waves through something it clearly doesn't understand. That gap is exactly what [GodotPrompter](https://github.com/jame581/GodotPrompter) exists to close — it gives AI coding agents structured, Godot 4.x-specific knowledge they load on demand instead of guessing from stale training data. v1.9.0 just landed, and it targets the three areas where agents tend to fail the hardest: **native extensions, multithreading, and mobile shipping.** The catalog goes from 45 to 48 skills. ## Why these three? It's not a coincidence that these were the gaps. They're the corners of Godot where the "obvious" answer is usually wrong, and where a hallucinated API costs you an hour of debugging instead of a quick fix. - **GDExtension** has its own binding macros, a strict `.gdextension` file format, and compatibility rules that aren't intuitive. Get a macro name wrong and nothing compiles. - **Multithreading** in Godot has hard safety rules — the main thread owns the scene tree, some servers are only thread-safe after you opt in, and `AStar` isn't thread-safe at all. An agent that doesn't know these will write code that races or crashes intermittently. - **Mobile** is a minefield of version gates. `JavaClassWrapper` is 4.4+, C# Android export needs .NET 9, v2 plugins are 4.2+. An agent without that context will happily mix features that can't coexist. ## What shipped `gdextension` — native extensions with godot-cpp (C++) and gdext (Rust). Covers when to actually go native versus staying in GDScript/C#, project and build setup, `ClassDB` class binding, the `.gdextension` file layout, the forward-but-not-backward compatibility rule, and calling your extension from both GDScript and C#. Reference files dig into the Rust path and native debugging. `multithreading` — `WorkerThreadPool` (the preferred high-level API), low-level `Thread`/`Mutex`/`Semaphore` for long-lived workers, `call_deferred` for safely handing results back to the main thread, and threaded resource loading with a real per-frame polling loop. Full C# parity, including the `System.Threading`/`Task` story and the `CallDeferred` snake-case gotcha that trips up C# users. A `pitfalls` reference covers deadlocks and data races. `mobile-development` — Android/iOS export and signing, app lifecycle notifications (autosave-on-background, the iOS ~5s budget), runtime permissions, the modern `JavaClassWrapper`/`AndroidRuntime` path for hitting Android APIs without a plugin, safe-area/notch handling, the mobile renderer and texture-compression budget, and C#-on-mobile caveats. References go deeper on plugins, IAP/ads, and crash debugging. This release also adds a new **Native & Performance** category to the catalog and wires all three skills into the cross-reference graph, so an agent already working in `godot-optimization` or `csharp-godot` gets pointed to them at the right moment. ## Grounded, not guessed The whole point of this project is to _not_ feed agents the same vague knowledge they already hallucinate from. So every one of these skills was authored against a local clone of the official Godot docs — real signatures, real macros, the actual `.gdextension` file format, all spot-verified against source. Where the official docs are silent (C# parity for the threading primitives, the threaded-loading polling loop, the permissions result callback), those examples are authored and clearly flagged as such rather than invented and presented as canon. Every `SKILL.md` stays under the 16 KB token budget, and the validator reports 0 errors at release. The repo-wide minimum is still Godot 4.3+, with anything that needs a newer engine (like `JavaClassWrapper` at 4.4+) labeled inline. ## Try it Claude Code: ``` claude plugins marketplace add jame581/skillsmith claude plugins install godot-prompter@skillsmith ``` Then just ask your agent something like _"export my game to Android with in-app purchases"_ or _"move this expensive pathfinding off the main thread"_ — it'll load the relevant skill and follow Godot 4 best practices instead of improvising. Gemini CLI, Copilot CLI, Cursor, Codex, and OpenCode are all supported too — install instructions are in the [README](https://github.com/jame581/GodotPrompter). ## Feedback welcome If you're building with Godot + AI agents, I'd genuinely like to know where your agents still go off the rails — that's how the skill gaps get found. There's a [GitHub Discussions](https://github.com/jame581/GodotPrompter/discussions) board for feature ideas, and issues/PRs are always open.
