Implementation Reference
- src/tools/jina-tools.ts:401-448 (handler)Handler for the 'search_image' tool (note: queried tool is 'search_images' but implementation is 'search_image'). Performs API call to Jina image search endpoint with query, handles authentication and errors, returns YAML serialized results.
