Get a single GitHub issue with full context: properties, project field values, relationships (parent, sub-issues, blocking, blocked-by), recent comments, and optional group detection. Returns group data by default so callers don
AI agents call ralph_hero__get_issue 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.
This tool retrieves and queries GitHub issue data including properties, field values, relationships, and comments. It performs read-only access to existing data with no side effects, no data modification, and no state changes. The 'optional group detection' feature is still a read operation. This falls squarely into the Read category.
From the tool's definition Tool name contains 'get_' and description states 'Get a single GitHub issue with full context' and 'Returns group data' - these are retrieval operations with no modification capability.
