AI agents call get_project_milestones to retrieve information from Repsona without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves milestone data from a specified project. It performs a read-only query without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal (unauthorized information disclosure only).
From the tool's definition Tool name 'get_project_milestones' and description indicate retrieval: '指定したプロジェクトのマイルストーン一覧を取得します' translates to 'Get a list of milestones for the specified project' — a query/fetch operation with no side effects.
