addFetchInfo

declare function addFetchInfo<T = Record<string, any>>(params: IFetchInfoToolParams<T>): string;
Copy

Creates and registers a fetch info tool for AI to retrieve data (READ pattern). This implements the READ side of the command pattern - AI calls tool to get information without modifying state.

Flow:

1. AI calls tool with parameters
2. validateParams runs (if provided) - validates parameters structure. Returns true if valid, false if invalid
3. If validation fails (returns false), tool execution is blocked
4. If validation passes, fetchContent executes - retrieves data
5. AI receives fetched content as tool output
6. If content is empty, emptyContent handler is called

Parameters

Parameter	Description
params	Configuration object for the fetch tool
