set_blueprint_class_defaults

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

With no annotations, the description carries full burden. It discloses that it modifies editable properties on CDO and accepts JSON-compatible values. However, it does not mention whether changes persist immediately, if the blueprint needs to be loaded, or if there are side effects like triggering recompilation. The transparency is adequate but not exhaustive.

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 concise: a one-sentence summary, scope clarification, usage modes, and an Args list. Every sentence adds value without redundancy. Front-loaded with purpose, then details. No wasted words.

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?

Given the tool's complexity (4 parameters, 0% schema coverage, no annotations, but has output schema), the description covers main functionality and parameter usage. Missing some contextual details like prerequisite (blueprint must be loaded) and whether changes auto-save, but overall sufficient for an agent to use correctly.

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 description coverage is 0%, so description compensates well. It explains blueprint_path format, the role of property_name/property_value for single setting, and properties dict for batch. It adds the 'JSON-compatible' constraint for values. However, it does not detail allowed types for property_value (e.g., nested objects) or keys in the properties dict, leaving some ambiguity.

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 explicitly states the tool sets default property values on a Blueprint's generated class CDO. It clarifies scope (works on all editable properties including C++ parent and BP-defined) and differentiates from siblings like get_blueprint_class_defaults and set_blueprint_variable_properties by focusing on defaults.

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 explains two usage modes (single property vs. batch via dict) but does not explicitly state when to use this tool over alternatives like set_blueprint_variable_properties or set_asset_property. No when-not-to-use guidance is provided, leaving the agent to infer context from the tool name and sibling list.

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