List assets (files, images) in a specific folder. Returns asset metadata including filename, type, size, and upload date.
AI agents call wikijs_list_assets to retrieve information from Requarks Wiki without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs only a read/query operation to retrieve and return metadata about existing assets. It does not create, modify, delete, execute code, or trigger external operations. The metadata returned (filename, type, size, upload date) are informational only. No data is changed or at risk of being deleted or damaged. This is a straightforward directory/inventory listing operation.
From the tool's definition Tool description states it 'List assets' and 'Returns asset metadata including filename, type, size, and upload date' — pure retrieval operations with no modification or side effects.
