DeepSeek Harness Plugin

windrover/dsh-prompt-optimizer

Category UI Enhancements Added 2026-10-17

A prompt optimizer for the conversation input tool row: pick a category (Basic / Context / Image) and a template, then the optimize button rewrites the draft in place, with cancel, elapsed time, token usage and one-click undo. Ships 15 templates — task-instruction rewriting with hard result-side constraints, step planning, safety-research framing for reverse-engineering requests, system-prompt role cards, and text-to-image / image-to-image prompt rewriting. Context templates read the last turns of the current session for coreference resolution. The host half registers two loopback-only routes and calls the harness model service instead of any API directly; a settings section exposes nine fields (provider and model override, reasoning effort, temperature, output-token cap, timeout, input-length and context budgets). Output guards check that user-written constraints survive and that no new method-side constraints are invented, and warn rather than auto-retry. Adapted for dsh 0.2.0-rc.2.

Install

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

dsh plugin --profile web add github:windrover/dsh-prompt-optimizer

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).
