Download by product layer

Start with the layer that matches your problem: Drive for everyday archive work on Windows and Finder fallback testing on macOS, MCP for agent memory in real projects, or Native for technical inspection.

Choose package Licensing phases

What it brings

  • Drive helps people who want safer archive actions without changing their file manager habits; Windows gets the richer shell workflow, macOS gets an open-temp/extract-here fallback package.
  • MCP helps AI-assisted projects keep decisions, gates and context in the project instead of in a hidden service.
  • Native helps developers inspect the engine directly before building automation or integrations around it.
  • All public packages are alpha previews with clear free-use boundaries and visible checksums.
ZIP on GitHub + installer alternatives

  • Self-signed Windows single-EXE installer and MSI installer for shell integration testing.

Windows + macOS + Ubuntu build kits

ITHZ Native Developer Preview

The C++20 engine and CLI layer for developers: AVX2/scalar Windows binaries, inspect/list/verify/extract/pack-folder commands and documented verification modes. macOS and Ubuntu build kits prepare real platform builds; ready non-Windows binaries still need platform build and smoke gates.

ITHZ-CFC v0.1-alpha-rc2 1.4 MB native-win64-rc2-macos-buildkit.20260605.1
  • AVX2 and scalar Windows CLI binaries.
  • macOS build kit for building and packaging ithz-native on a real Mac.
  • Ubuntu source build kit for building and smoking ithz-native on Ubuntu.
  • Inspect, list, verify, extract and pack-folder commands.
  • Safe/full-no-write verification language.
  • Native engine documentation and SHA256SUMS.txt.

Agent prompt

Install MCP and Drive by OS

Copy the short prompt into Codex, Claude Code, Antigravity, Cursor or another local agent opened in the target project. The detailed workflow lives in `install_ithz.md` inside the package.

Windows 
Download the official Windows ITHZ-MCP package from https://ithz.dev/download/, unzip it outside the project, find install_ithz.md inside it, and follow that file to install ITHZ-MCP and ITHZ Drive into this current project. Do not invent steps, do not use unofficial sources, and do not commit anything automatically.
macOS 
Download the official macOS ITHZ-MCP package from https://ithz.dev/download/, unzip it outside the project, find install_ithz.md inside it, and follow that file to install ITHZ-MCP into this current project. If macOS ithz-native is missing, do not ask an A/B/C/D question: install the supported MCP/Git/Drive fallback and report the native-binary gap. Do not invent steps and do not commit anything automatically.
Ubuntu/Linux 
Download the official Ubuntu/Linux ITHZ-MCP package from https://ithz.dev/download/, unzip it outside the project, find install_ithz.md inside it, and follow that file to install ITHZ-MCP and the available Drive/open-temp fallback into this current project. Do not invent steps, do not use unofficial sources, and do not commit anything automatically.

These prompts are intentionally short. The detailed decision tree, memory import, smoke tests, cleanup and macOS fallback live in `install_ithz.md` inside the package. ITHZ-MCP does not replace Git and should not commit changes automatically.
