Create Component Set

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

Annotations include only openWorldHint: true, which does not capture safety or side effects. The description states 'Combine components into a component set' but does not disclose that the operation may mutate the source components, alter their parent container, or require specific permissions. This leaves the agent without critical behavioral context for a create/mutation operation.

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 a single concise sentence of 11 words that captures the core action and key distinguishing detail. No unnecessary words; structurally ideal.

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 complete parameter schema, existing output schema, and an annotation, the description is adequate but not fully complete. It omits clarifying how propertyValues map positionally to properties (though schema hints at this) and does not explain the practical effect on the component set's parent hierarchy. However, the overall context from schema is strong.

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 100%, with each parameter having a descriptive comment (e.g., parentId explains it is an appendable container and references node_info). The description itself adds no additional parameter semantics, so the baseline score of 3 applies.

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 uses the active verb 'Combine' and specifically names the resource 'component set (variants) with property definitions,' making it clear what the tool accomplishes. It differentiates from sibling tools like create_component and create_instance by its focus on combining multiple components into a set.

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 does not explicitly mention when to use this tool versus alternatives such as create_component or component_manage_property. It implies that it is used when existing components need to be combined into a set, but provides no explicit exclusions or alternative suggestions.

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