create_spline_placement_blueprint

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

With no annotations, the description carries the burden of behavior disclosure. It usefully describes the generated blueprint's structure and algorithm (spline component, ISM, construction script using GetLocationAtDistanceAlongSpline), but it does not disclose tool-level side effects such as whether existing assets are overwritten, whether the blueprint is saved/compiled, or how invalid paths are handled.

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 with a headline, component bullet list, Args block, KB link, and example. It is not bloated, though 'From Ch. 19' and the no-argument example add marginal value. The organization makes the information easy to scan.

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 blueprint creation tool with an output schema, the description covers the generated asset's components and parameters well. However, it omits important operational context such as whether the blueprint is automatically saved/compiled, what happens on name conflicts, and any prerequisites for the static mesh asset. The KB reference helps but does not fill those gaps.

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 input schema has 0% description coverage, so the description's Args section is essential. It gives concise, useful meanings for all four parameters: name, static_mesh_path, default_space_between_instances, and folder_path. It does not specify units for spacing or validation rules, but it fully compensates for the schema's lack of descriptions.

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 a Blueprint that places Static Mesh instances along a Spline component.' It then enumerates the exact components and construction-script behavior, which makes the tool's purpose unmistakable and distinguishes it from the many lower-level add_* node tools in the sibling list.

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 explicit guidance on when to choose this tool over alternatives like add_spline_component, create_blueprint, or add_instanced_static_mesh_component. The description implies a spline-placement use case but never states prerequisites, exclusions, or a preferred workflow.

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