add_create_save_game_object_node

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the burden. It explains the node's purpose and ordering context, but doesn't disclose side effects such as whether the node is automatically wired into the graph, what happens to existing variables, or whether compilation occurs. Some behavior is implied but not fully transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and well-structured: a one-sentence summary, contextual use guidance, an Args list, a KB reference, and an example. It is front-loaded with the core purpose and avoids excessive length, though the example and Ch. 11 reference are slightly redundant with the prose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers purpose, context, and parameters, plus a minimal example. It doesn't explain the tool's output schema or return behavior, but the output schema itself may provide that. Given the tool's moderate complexity and the save-system sibling set, the description is fairly complete and would guide the agent well.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description must compensate. It lists all four args with brief explanations, but these mostly restate the parameter names (blueprint_name, save_game_class, output_variable, node_position). It adds minimal insight into formats or how the node_position array is interpreted, though the example provides some concrete guidance.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool adds a CreateSaveGameObject node to instantiate a new SaveGame object, with a specific context (when no save file exists yet). It names the operation and resource, and mentions the prerequisite SaveGameToSlot, though it doesn't explicitly distinguish from sibling save-system node tools beyond that.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives explicit guidance: used when no save file exists yet and should be called before SaveGameToSlot. It references Ch. 11 and the knowledge base, giving helpful context, though it doesn't explicitly list alternatives or when-not-to-use beyond the save-system workflow.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
