AI agents call get_environment_forks to retrieve information from Postman without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/queries environment fork data without modifying, deleting, or executing any operations. It is a straightforward read operation that poses minimal risk if misused by an AI agent, as it only returns information about existing environment forks.
From the tool's definition Tool name is 'get_environment_forks' with description 'Get a list of environment forks'. The verb 'Get' and action of retrieving a list indicate data retrieval with no side effects.
