This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

dsh-free-search

A free, multi-source web search plugin for DeepSeek Harness (dsh).

Registers as a search provider on dsh's native web seam, so the built-in web_search tool runs on a free engine chain with native citation cards — and stops burning DeepSeek API credits (the base layer's default deepseek-official route costs one model call per search).

Engine chain (all free, automatic failover)

Tavilykeyless by default; keyed when TAVILY_API_KEY is setalways (primary)keyed mode adds answer summaries

Priority: a matched specialized engine runs first, then Tavily keyless → Sogou; a failing engine is skipped automatically, and when all fail the error lists every attempt. Optional env: TAVILY_API_KEY.

Install

dsh plugin --profile web add "github:zhouzhencheng07/dsh-free-search"

The package declares dsh.bundle.patch, so it is activated as a profile bundle layer (not just an inert dependency). Restart dsh web after installing; the built-in web_search then runs on the free engine chain.

Local development

# local development: replace the path with your local checkout directory
dsh plugin --profile web add "file:/path/to/dsh-free-search"

> If you previously loaded this plugin via a --patch ./scratch-plugin/... > flag, remove that flag from the launch command — the bundle now owns the > free-search row, and a duplicate insert would fail to boot.

How it works

  • src/web-search.js: ctx.web.registerSearchProvider({ id: 'free-search', ... }).
  • src/engine-chain.js: engine priority, query routing (specialized engines

join on query signals), failover, timeout and cancellation (AbortSignal forwarding).

  • src/engines/*.js: per-engine requests and normalization into a uniform

{ url, title?, snippet?, publishedAt? } item list.

  • cordis.patch.yml: repoints the web row's searchProvider from

deepseek-official to free-search (that row's config has only this one base key, so a wholesale replacement is safe; a later profile patch can pin any provider back).

Requirements

  • Node.js ≥ 22 (dsh requirement)
  • No API key required; plain ESM, zero dependencies, zero build step
