AI agents call get_saved_web_pages to retrieve information from Inoreader without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
get_saved_web_pages performs a data retrieval operation (listing/filtering saved pages). The description explicitly states it 'lists' saved web pages and 'supports filtering'; there are no side effects, modifications, deletions, or external code execution. This is a straightforward Read operation. The 'cleanup candidates' reference indicates filtering capability, not deletion capability.
From the tool's definition Tool lists saved web pages with filtering capabilities; operations are purely retrievals with no mention of modifying, deleting, or executing operations.
