DeepSeek Harness is a local Agent runtime for developers (developer preview). See deepseek.com/harness and deepseek-ai/deepseek-harness. A common quick start is npx @deepseek-ai/dsh web; the local UI often appears at 127.0.0.1:3080. It is not Youdao Translate and not a store APK. Use Youdao lookup / text or document translate to understand English docs and errors; install the client from /en/download/.
Typical scene: half a README of jargon, or a terminal full of English Node errors you want to skim before deciding whether to reinstall. Youdao helps with meanings and paragraphs; it does not start dsh for you. Keep the split below.
Public Harness facts worth jotting down
Public pages describe a plugin-based stack: models, tools, skills, sessions, sandbox, UI, and more compose as plugins. Developer preview means iteration continues. Mode names (Standard, PTC, Minimal, Creation, and whatever your page shows) follow the live docs—this article does not invent unpublished APIs or turn the preview into a store app.
Install paths are Node + npx or cloning the repo per README—not searching phone stores for “Harness translate.” Treating an APK as Harness, or Youdao as the Harness installer, puts you on the wrong shelf.
Official site and GitHub: lookup vs longer translate
Single terms beside a plugin name: lookup/selection is faster and keeps code blocks readable. Whole “design” or “quick start” sections: paste into Youdao text/document entry (labels follow your build) for gist, then return to English to copy commands.
Code fences, one-line bash, and the package @deepseek-ai/dsh: copy English only. Full-width punctuation or split package names from a translation will fail in the terminal.
Translate vs dictionary boundaries: see translate vs dictionary. Document-job failures are a different track from “I need to understand this English paragraph.”
Using Youdao on English terminal errors
Copy the full English stack or the first Error: line. Translate for gist—dependency missing, permissions, port in use, network. When searching GitHub Issues or other indexes, keep English keywords; localized names often miss hits.
If paths, filenames, or env vars become Chinese in the translation, trust the terminal original. Mojibake or tofu boxes in Youdao’s result pane are font/encoding issues—see the garbled-text article, not a broken Harness install.
Local :3080 UI plus Youdao
When the Harness Web UI opens in a browser, chrome text may be English. Lookup short labels, or paste help strings into Youdao. Full-page bilingual overlay is not the main desktop-Youdao path—do not expect a “one-click Chinese Harness.”
Cannot reach 127.0.0.1:3080: check whether the process started, whether the terminal printed another port, and local firewall—unrelated to whether Youdao is installed. Youdao won’t open or crashes: use client troubleshooting posts; do not reinstall Node as a lucky charm.
Install Youdao from the download page only
Platform packages and availability notes follow /en/download/. After install, translate one short English sentence to confirm the result pane works, then return to Harness docs. Update failures and offline-pack issues have their own posts—do not mix them with Agent runtime debugging.
When to stop
Docs make sense and commands are copied correctly, but npx fails: return to the repo README/Issues and check Node and network. Youdao returns text but display is broken: garbled-text article. No translation at all: document/photo failure tracks. Preview menus renamed: trust the page you have open; stale screenshots are hints only.
