About this plugin
DeepSeek Harness ships with a built-in web search, but it does not fit every workflow. Some users prefer the retrieval quality of Codex, or already hold an OpenAI API key they want to reuse without spinning up a separate search service. dsh-web-search-codex fills that gap: it registers a codex search provider in the Web Runtime and forwards every web-search request to a /alpha/search-compatible endpoint you configure, plugging Harness into the Codex search ecosystem with minimal setup.
Configuration offers two paths. If you have already set up an OpenAI provider in model settings, choosing "Reuse OpenAI" lets the plugin derive the /alpha/search URL from your existing base URL and reuse the current key automatically. Alternatively, the "Standalone Key" mode lets you supply a complete /alpha/search URL and a dedicated API Key. On the security side, the plugin sends only the current search query, never reads conversation history, rejects all HTTP redirects to prevent key leakage, and supports both HTTP and HTTPS.
This plugin is best suited for users who already have Codex or OpenAI API access and want a consistent search experience inside Harness. Keep in mind that once installed, the default web search is replaced by the codex provider, /alpha/search is an internal Codex alpha protocol rather than a stable public API, and failed requests will not automatically fall back to DeepSeek Search.
Use Cases
- Switch the default web search in Harness to a Codex /alpha/search endpoint
- Reuse an existing OpenAI API Key configuration instead of registering a new search service
- Connect to the Codex search pipeline with a standalone key and full endpoint URL
Best For
- Users who already hold OpenAI or Codex API credits and want a unified search experience in Harness
- Users who prefer Codex retrieval quality over the default search provider
- Teams or individuals who need to manage search credentials separately from model keys
