AI agents call list_offers to retrieve information from Agent Planets without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The 'browse' verb confirms passive data retrieval. No execution of arbitrary code, no deletion, no financial transactions—only information access.
