dsh-web-search-ddg

DeepSeek Harness is free software, yet web search has been the one feature locked behind a paywall: every built-in provider demands a DeepSeek platform key, an Exa account, or a Perplexity subscription, while closed-source tools bundle live search into their paid plans. dsh-web-search-ddg removes that barrier entirely. It scrapes DuckDuckGo's lite results page over plain HTTP, requiring no API key, no account, no credit card, and burning zero auxiliary model tokens. One search costs exactly one ordinary HTTP fetch.

On the parsing side, the plugin accepts only anchors explicitly marked as DuckDuckGo results and raises WEB_PROVIDER_ERROR when zero items are found rather than silently returning an empty array. /l/?uddg= redirect wrappers are unwrapped to their real targets, internal and duplicate URLs are dropped, and HTML entity decoding is ordered to prevent double-decode artifacts. Queries can be sent via GET or POST, giving deployments a fallback when anomaly detection blocks the other. The package reads nothing from the credentials vault, ships with no install or postinstall scripts, and pins every dependency to a bounded caret range, keeping the supply-chain attack surface minimal.

If you run a coding agent inside DeepSeek Harness and would rather not sign up for a paid search API, worry about key rotation, or hit a trial-expiry cliff, this plugin gives you a search capability that lives in your own checkout: auditable, patchable, and yours to keep. It is also a natural fit for developers who care about supply-chain security and prefer a fully local, inspectable toolchain.
