DeepSeek Harness Plugin

Category UI Enhancements Added 2026-11-10

Per-conversation system prompt studio for DeepSeek Harness. Append text, shadow-replace one named first-party prompt section, or replace the whole system prompt; changes apply on the next model request without a restart. Overrides persist per session and are inherited by forked conversations along the parent chain, with a Pin action to freeze the inherited result locally. The panel lists the real assembled sections and guards unsaved edits.

Install

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

dsh plugin --profile web add github:user-Mrz/dsh-system-prompt-studio

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).
