ue_set_class_defaults

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

With no annotations, the description must disclose behaviors. It only states the operation, but fails to mention side effects, persistence, triggers for compilation, or whether it affects existing instances. Critical behavioral traits are missing.

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 with a clear structure (function statement followed by argument list). It avoids unnecessary words and uses an efficient format. However, the use of Italian may limit accessibility for English-speaking agents.

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 lack of annotations, output schema, and detailed schema descriptions, the description is too minimal. It does not explain return values, prerequisites, or how this tool differs from similar ones like ue_set_actor_property, leaving the agent underinformed.

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?

The description adds meaning for both parameters: blueprint_path as 'path of the Blueprint' and properties as a map with an example. However, it does not elaborate on path format, valid property names, or type constraints, which would be helpful given the 0% schema coverage.

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's function: setting the Class Defaults (CDO) of a Blueprint. The verb 'set' and resource 'Class Defaults' are specific, and it is distinguishable from sibling tools like ue_set_actor_property.

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?

No guidance is provided on when to use this tool versus alternatives like ue_set_actor_property or ue_compile_blueprint. There is no mention of prerequisites, contexts, or exclusions, leaving the agent without usage direction.

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