Write C/C++ in the Xenolith/Stappler monorepo the way the codebase is written. Use BEFORE creating or editing sources in runtime/, stappler/, xenolith/, tests/ or utils/ — new file, new header, new class, new platform branch, new allocation. Covers .cpp SCU…
Write CSS for the Xenolith/Stappler engine's CSS engine (stappler_document + xenolith_renderer_ui StyleSystem) CORRECTLY — it is a CSS subset, NOT web CSS. Use before writing or debugging any .css in this repo (resources/style.css, pug templates, ui:: atoms).…
Debug and drive a Xenolith app over its inspector socket — headless by default (`--headless`, no window system), so a GUI can be inspected, screenshotted and driven with no display, no compositor and no mouse. MCP tools: `inspect_scene` (the node tree),…
Debug a Windows (.exe) build under wine from native linux lldb — catch a crash, access violation, or stack overflow and get a source-level backtrace, registers, and locals, all on Linux without a Windows machine. Use when a Windows/MSVC cross-build…
Build & compile-verify a Xenolith/Stappler project for any target (Linux, Windows, Android-NDK, macOS). Prefer xenolith-cli; use raw make only when the CLI is not installed. Use when asked to build, compile-check, or verify a change in this monorepo —…
Build Xenolith apps/projects through the `xenolith-cli` installer tool — the SDK command front-end. Use whenever asked to build, rebuild, run, or compile-check a Xenolith project or app in this repo (e.g. "build the installer", "build utils/installer",…
Build a Xenolith wasm test, serve it with COOP/COEP, and open it in the browser. Use when someone wants to run/see a wasm test (libc, threads, WebGPU) locally without manual build+serve steps.
