codework-exa-search

Exa AI web search tool plugin for CodeWork.

It registers the exa_search tool (plugin ID exa.tool.search), letting agents search the live web and read extracted text highlights.

Installation

codework plugin add codework-exa-search          # this project (.codework/settings.jsonc)
codework plugin add codework-exa-search -g       # every project (your user settings)

plugin add records the entry and installs it. On a fresh checkout that already declares it, run codework plugin install.

Configuration

Configure it with a second entry that names the plugin, next to the one that loads it:

// .codework/settings.jsonc or ~/.codework/settings.jsonc
{
  "plugins": [
    "codework-exa-search",
    {
      "plugin": "exa.tool.search",
      "options": { "defaultNumResults": 5 }
    }
  ]
}

The configuration entry only sets options; it never loads anything. It can also address the plugin by the string that loaded it ("package": "codework-exa-search"), or turn it off in one project that inherits it from user settings ("enabled": false).

Prefer the EXA_API_KEY environment variable to options.apiKey, so the key stays out of a settings file you might commit.

Configuration Options

| Option | Type | Default | Description | | --- | --- | --- | --- | | apiKey | string | process.env.EXA_API_KEY | Your Exa API key. | | defaultNumResults | number | 5 | Default number of search results to return (clamped between 1 and 20). |

Tool: exa_search

Searches the web via Exa AI.

Parameters

• query (string, required): The search query to look up on the web.
• numResults (number, optional): Number of results to return (1-20).
• type ("auto" | "fast" | "instant" | "deep", optional): auto (default) balances quality and speed, fast/instant trade depth for latency, deep is slower and more thorough.
• includeDomains (string[], optional): Restrict search to specific domains.
• excludeDomains (string[], optional): Exclude specific domains from search.
