Implementation Reference
- src/neem/mcp/tools/hocuspocus.py:706-772 (handler)The @server.tool decorator registers the tool and defines its metadata (name, title, description). The async rename_artifact_tool function is the core handler that authenticates, validates inputs, verifies the artifact exists in the workspace, performs the rename via Y.js WorkspaceWriter.update_artifact in a transaction, fetches updated workspace snapshot, and returns success response with details.
