dsh-windows-native

Running DeepSeek Harness straight on Windows PowerShell — no WSL — quickly reveals the same handful of mistakes the agent keeps making: chaining commands with &&, trusting mojibake Chinese output as if the data itself were corrupted, assuming a junction was created because the exit code was zero. dsh-windows-native is a system-prompt injection plugin that lays every one of these traps out up front so the agent stops guessing.

It covers roughly fifteen real Windows/PowerShell pitfalls, each one a scar on the author's machine: use semicolons instead of && or ||, the console is not UTF-8 so non-ASCII output looks wrong even when the data is fine, multi-line non-ASCII text should be written to a file before execution, Python subprocess needs an explicit encoding, .bat script bodies must stay pure ASCII, Set-Content defaults to the system ANSI codepage, nested SSH quotes can hang silently for minutes, NUL is reserved so > /dev/null leaves a literal file behind, Docker drive-letter colons can mis-split a mount and the container still reports healthy, native .node bindings crash on Linux, killing the outer process does not free the port, and hiding a Scheduled Task actually requires pythonw.exe with CREATE_NO_WINDOW. None of it is theoretical.

It is aimed at developers who run DeepSeek Harness natively in Windows PowerShell rather than inside WSL, particularly in Chinese-language environments where GBK and UTF-8 constantly collide. The plugin bridges no environment and changes no configuration; it simply writes hard-won experience into the agent's context so it stops repeating the mistakes you already made.
