create_umg_widget_blueprint

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It explains that an asset is created with a default path and parent class, but does not address overwrite/collision behavior, compile/open effects, or content-browser side effects. The example also passes a full asset path as widget_name, which conflicts with the stated 'asset name' parameter.

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 front-loaded: a clear purpose sentence, an Args block, a KB pointer, and a short example. It earns its length, though the misleading example is a content issue rather than a structural one.

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?

For a creation tool with no annotations, this description is thin: it lacks overwrite/naming behavior, parent-class constraints, path format rules, and alternative routing. The KB pointer and output schema provide some support, but the description alone leaves an agent uncertain about edge cases when calling the tool.

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?

All three parameters are listed with defaults, partially compensating for the 0% schema description coverage, and widget_name includes naming examples. However, parent_class and path mostly restate the schema titles, and the example's full-path value for widget_name directly contradicts the 'asset name' definition, leaving invocation semantics ambiguous.

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 opening sentence states a specific verb and resource ('Create a new UMG Widget Blueprint'), and the Args section reinforces the intended asset type. It does not explicitly differentiate from sibling creation tools like create_hud_widget or create_blueprint, so it falls short of a 5.

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 when-to-use guidance is provided, and no alternatives or exclusions are mentioned. The KB pointer suggests a documentation source but does not help an agent decide between this and sibling widget/blueprint creation tools.

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