native

Discovery skill for the Native SDK, the complete toolkit for building native desktop applications. Apps are authored in TypeScript + declarative Native markup (.native) by default and compiled to native code with no JS runtime in the binary; Zig cores are an explicit alternative, and WebViews are the optional web-content path. Use when the user asks what the Native SDK is, how to build a Native SDK app, author native UI, scaffold an app, configure app.json or legacy app.zon, add bridge commands, embed web content, package an app, test a running app, or automate a Native SDK app.

Zig 0.16 idioms for Native SDK code, indexed by compile error. Load when `zig build` fails on std APIs with errors like "struct 'fs' has no member named 'cwd'", "struct 'array_list.Aligned(u8,null)' has no member named 'init'", "struct 'std' has no member named 'io'", "no member named 'GeneralPurposeAllocator'", "no member named 'getEnvMap'", or "invalid format string" - the signature of code written for Zig 0.15 or earlier. Covers main(std.process.Init), std.Io file IO and writers, ArrayList, process spawning, environment, clocks and sleep, sockets, custom formatting, and build.zig module shapes, each as this SDK writes them.

Authoring guide for TypeScript app cores - Model, Msg, update, and the pure functions they call, written in the closed app-core subset and compiled ahead-of-time to arena-backed Zig by the @native-sdk/core transpiler. Use when writing or modifying a src/core.ts app core, fixing subset checker errors (NS1001-NS1060), or deciding how to express state, messages, text (bytes and the byte-text string methods), text input, continuous controls (sliders, scroll), effects (Cmd), subscriptions (Sub), the host-event wiring channels (frameMsg, keyMsg, appearanceMsg, chromeMsg, envMsgs, app.zon assets), derived values, the view_unbound lint opt-out, local mutation of owned arrays, or how to split a core into modules under src/ (relative imports, namespace imports, @native-sdk/core/text, @native-sdk/core/events).

Authoring guide for the Native markup (.native) view tier of native-rendered Native SDK apps. TypeScript cores are the default and use this skill together with ts-core; Zig cores are an explicit alternative and this guide labels their lower-level UiApp recipes. Use when building or modifying native UI (widgets, layout, bindings, messages), writing .native files, wiring views to Model/Msg/update, testing markup views, or verifying a native app through the automation harness.

Core Native SDK guide for AI agents. Read this before explaining the Native SDK or changing a Native SDK app. Covers the mental model (native-rendered apps by default, WebView shells as a coexisting architecture), project structure, app.zon, App and Runtime patterns, frontend integration, web engines, JavaScript bridge commands, permissions, windows, WebViews, dialogs, packaging, debugging, testing, and when to load deeper references. For authoring native-rendered UI (Native markup .native views, Model/Msg/update, UiApp), load the native-ui skill. Use when the user asks what the Native SDK is, how to build or modify an app, how to package or debug it, or how to add native capabilities.

Automation and verification guide for running Native SDK apps. Use when the user asks to test a running app, inspect runtime state, list windows, wait for readiness, drive widgets, take deterministic screenshots, send bridge commands, debug why automation is not connected, create smoke tests, or verify a Native SDK example in a GUI-capable session.
