wendy-lite — Claude Code skill for WASM on ESP32-C6
Get guidance for building WASM apps that run on Wendy Lite firmware for ESP32-C6. Useful when your app needs to reach device hardware from C, Rust, Swift, or Zig.
npx skills add wendylabsinc/claude-skills --skill wendy-lite -a claude-codeWhat wendy-lite does
The skill explains the structure of a Wendy Lite WASM app, including its _start entry point, imports from the wendy module, and the callback export used for asynchronous events. It covers device interfaces such as GPIO, I2C, UART, SPI, and timers, along with app build and upload workflows.
Swift projects need Swift 6.0 or newer with Embedded Swift support, and the documented approach avoids heap allocation. Rust, Zig, and WAT have their own build commands and tool requirements. Check that your language and toolchain fit these constraints before building. The guidance also points to references for the WASM API, firmware configuration, and Swift SDK.
What it helps with
- build a WASM app for Wendy Lite
- set up the
_startentry point - access GPIO or I2C from WASM
- handle asynchronous device callbacks
- choose a build path for Swift, Rust, or Zig
Example prompts for the agent
- Help me build a C WASM app for Wendy Lite on ESP32-C6.
- Show me how to access GPIO from WASM and handle callbacks.
- Check the Embedded Swift requirements for a Wendy Lite app.
