dsh-web-search-chrome

A free search provider for the DeepSeek Harness web capability seam (ctx.web). It drives your local Chrome through the agent-browser CLI — headless by default, with a persistent --profile directory — and needs no paid search API and no API key.

• Provider id: local-chrome
• Search engine: Bing by default (engine: bing), Google available via engine: google (Google is frequently gated by IP-reputation anti-bot walls on VPN/datacenter networks; Bing tolerates them far better — see docs/decisions-010.md §D7)
• Model-facing web_search tool: zero changes — switching the seam's searchProvider is a one-line patch.
• Every result carries url + title + snippet (+ best-effort publishedAt), exactly the shape dsh-web defines.

⚠️ Privacy (read first): search terms are sent to the search engine from your machine, enter the local Chrome profile's history, and are subject to the engine's normal tracking. Searches run in a dedicated new tab that is closed when the search finishes; your existing tabs are never touched. There is no login state in 0.1 — a fresh, dedicated profile directory is used.

How it works

dsh agent's web_search tool (unchanged)
        ↓ ctx.web.search()
dsh-web-search-chrome  (provider id: local-chrome)
        ↓ serialized subprocess calls
agent-browser CLI  (≥ 0.34.0)
        ↓ --profile 
  [--headed]
local Chrome  →  bing.com/search?q=&count=&setlang=   (engine: google → google.com/search)
        ↓ SERP extraction (in-page JS, per-engine selectors)
title / url / snippet / publishedAt  →  WebSearchSource[]

Per search: open a new labeled tab → wait for the DOM → extract the SERP → close the tab. Searches are strictly serialized (one browser instance, one search at a time). Results are cached: in-session (same query returns instantly) and on disk (JSON + TTL, default 24 h).

Installation

1. Install the CLI and a browser

agent-browser is the only runtime dependency (it bundles/installs Chrome for Testing itself):
