DeepSeek Harness Plugin

sezhiyanhua/dsh-dual-mode

Category UI Enhancements Added 2026-11-12

Adds a top-left Harness/Chat switcher and a web-chat workspace that drives your own logged-in chat.deepseek.com session in a persistent headless browser, with one-click task extraction to a Harness session and results sent back to the web chat. Starts a persistent Chrome or Edge profile with remote debugging on 127.0.0.1:9410 that keeps your chat.deepseek.com login; its /dual-mode routes have no DSH access check and can create Harness tasks from the web chat.

Install

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

dsh plugin --profile web add github:sezhiyanhua/dsh-dual-mode

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).
