Create Component Set

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

The description only states the basic purpose but lacks details on behavioral aspects not covered by annotations (openWorldHint). For instance, it does not explain whether the original components are preserved, how property values map, or what happens to existing component sets. The annotation only hints at undefined output, but the description does not elaborate on mutation or side effects.

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 with no redundant information. It is front-loaded with the core action. However, it could be slightly more structured to separate purpose from parameter hints, but overall it is efficient.

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 with 5 parameters and an output schema, the description is too brief. It does not explain the expected relationship between 'properties' and 'propertyValues', or the requirement that 'parentId' or 'parentNodeName' must be provided together. The output schema exists but the description does not complement it with usage context, leaving 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 100% description coverage, so parameters are already documented. The description adds no extra meaning beyond the schema; it does not clarify parameter semantics like the ordering of property values or validation rules. Baseline score of 3 applies due to high 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 action: 'Combine components into a component set (variants) with property definitions.' This uses a specific verb ('Combine') and resource ('components into a component set'), and distinguishes it from sibling tools like 'create_component' which creates a single component.

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 no guidance on when to use this tool versus alternatives such as 'create_component' or other node creation tools. It does not mention prerequisites, limitations, or contextual cues for invocation.

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