List all blocking dependencies for a GitHub issue. Returns both
AI agents call ralph_hero__list_dependencies to retrieve information from Ralph Hero without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and displays information about issue dependencies without modifying, executing, or deleting anything. It is a straightforward read operation that returns data about existing GitHub issue relationships. The low severity reflects minimal risk—misuse would only expose information about issue blocking relationships, which is typically non-sensitive project metadata.
From the tool's definition Tool name includes 'list' and description states 'List all blocking dependencies for a GitHub issue.' This is a query/retrieval operation with no side effects.
