Zipic

Image compression on macOS and Windows, 100% on-device. Drive the installed GUI via its CLI; URL Scheme is a fallback when the CLI is unavailable.

Platform and shell

Identify the OS, architecture and shell where commands execute, rather than the user's desktop OS. Keep the GUI, CLI and input/output paths on the same host and user account.

• macOS: use zipic and POSIX shell syntax. If missing, run bash "<skill-dir>/scripts/detect.sh".
• Native Windows: read reference/windows.md before setup or compression. Use PowerShell and zipic.exe; run & "<skill-dir>\scripts\detect.ps1" to resolve the executable and verify its version. The packaged CLI is ZipicCli.exe, exposed as the zipic.exe app execution alias; the GUI's Zipic.exe is a different executable.
• WSL: there is no Linux Zipic binary. Use Windows PowerShell through WSL interop with paths converted by wslpath -w, following the Windows reference. A Linux container or remote Linux host without Windows interop cannot invoke the Windows GUI.

Resolve <skill-dir> from this loaded skill's location; script paths are not relative to the user's project. On Windows use & $exe for a resolved executable, $env:NAME for environment variables, quoted paths and argument arrays. Do not copy Bash continuations, open, brew or /tmp paths into PowerShell.
