create_product_configurator_blueprint

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

With no annotations, the description carries the behavioral burden, and it does so well by listing three concrete runtime behaviors: holding a Variant Sets reference, iterating sets/variants on BeginPlay, and binding buttons to ActivateVariant. It also implies the tool creates a Widget Blueprint. It could further disclose whether assets are saved/compiled or whether the referenced Variant Sets asset must pre-exist, but the disclosed behavior is substantive.

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 well-structured: a one-line purpose, a numbered behavioral list, an Args block, a KB pointer, and an example call. It is slightly repetitive (the final 'mirrors the product configurator pattern' rephrases the opening line) but stays compact and scannable.

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 tool that creates a blueprint with specific wiring and widget generation, the description covers the core workflow, parameters, source reference, and an example. An output schema exists, so return-value documentation is not needed. Minor gaps include whether the Level Variant Sets asset must already exist and whether the created blueprint is compiled/saved, but the description is otherwise sufficient for invoking 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?

Schema description coverage is 0%, so the description must compensate. The Args section gives each of the four parameters a plain-language meaning (e.g., 'Level Variant Sets asset to reference', 'Widget Blueprint to create for the UI'), which goes beyond the bare names in the schema. Coverage is complete, though not deeply detailed about constraints or naming conventions.

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 opens with a specific verb and resource: 'Create the BP_Configurator Blueprint from Ch. 20.' It then enumerates exactly what the blueprint does (holds a Variant Sets reference, builds UMG widgets, binds ActivateVariant), making it clearly distinct from generic blueprint-creation siblings like create_blueprint or create_umg_widget_blueprint.

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 provides clear context: this tool implements the book's product configurator pattern with dynamically generated UI from variant set data. It does not explicitly state when not to use it or name alternatives, but the 'mirrors the product configurator pattern' phrase strongly signals the intended use case.

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