DeepSeek Harness Plugin

th3r-dev/th3-plug#shell

Category Tools & Capabilities Added 2026-11-10

Runs a shell command on your machine from the chat box with !cmd or /sh cmd, without sending a model request. The output comes back as your message plus a terminal card with the exit code, run time and a Copy button. While a ! line is typed, a menu offers zsh completions from your own fpath and matching commands from your shell history. Commands run as a login shell in the session folder, outside the agent sandbox, with a 120 s default timeout.

Install

# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)

dsh plugin --profile web add github:th3r-dev/th3-plug#path:/plugs/shell

Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).
