cmd 2

dsh-shell for DeepSeek Harness: runs cmd / PowerShell commands on Windows (and bash-like shells on POSIX) with a bash-inspired safety model — timeouts, output truncation, exit codes, background jobs and a cwd allowlist

DeepSeek Harness plugin: one model-facing `shell` tool whose shell is a user setting. Resolves and validates through the harness's own seams, and refuses to run when the selected shell cannot be confined.
