AI agents call get_journeys_for_release to retrieve information from Blop without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and filters existing journey data by release brief or app_url parameters. It has no side effects, cannot modify state, and merely returns information about pre-recorded journeys. This is a straightforward Read operation with minimal blast radius—misuse would only expose metadata about test journeys, not trigger unintended actions or compromise systems.
From the tool's definition Tool name contains 'get_' and description states 'List recorded journeys' — a retrieval operation with no modification, deletion, or execution of code/scripts.
