# Changelog

All notable changes to `@izhimu/pi-rtk` will be documented in this file.

## [0.1.5] - 2026-08-21

### Changed & Improved
- **Zero-Overhead Transparent Rewrite**: Removed redundant bottom status bar and prompt skills to keep prompt overhead at zero; the model works naturally with raw shell commands while RTK rewrites them transparently.
- **Protocol Compliance**: Standardized `pi.sendMessage` payload structure (`customType: "rtk-status"`, `display: true`) for seamless compatibility with both Pi and Oh My Pi runtimes.
- **Type Checking**: Added `typecheck` script and type definitions to repository tooling.

### Changed
