Release builds aren't code-signed yet, so your OS will ask you to confirm the first time you open Jimothy.

brew install --cask echelonone-io/tap/jimothy.dmg and drag Jimothy to Applications.xattr -dr com.apple.quarantine /Applications/Jimothy.appJimothy-windows-x64.exe.

chmod +x Jimothy-*.AppImage && ./Jimothy-*.AppImagesudo apt install ./jimothy_*_amd64.debsudo pacman -U jimothy-*.pacmanThe built-in Simulator harness lets you try the whole flow without installing anything. For real work, install at least one agent, such as Claude Code or Codex. Jimothy detects it automatically.
