create_component

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

With no annotations, the description must bear full behavioral disclosure. It only states 'transforms' without revealing whether the operation is destructive, reversible, or requires special permissions. It does not describe side effects or return behavior.

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 unnecessary words. However, it could benefit from structured separation of purpose and usage details. Nonetheless, it is not verbose.

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?

The description is too brief given the complexity of the operation and the absence of annotations and output schema. It fails to explain key aspects like whether the frame is mutated, what 'verify against' means for nodeName, or what is returned. Sibling tools suggest a richer component system, but this description leaves critical 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?

Input schema has 100% description coverage, so the schema already defines both parameters. The description adds no additional meaning beyond the schema. Baseline 3 is appropriate as it does not reduce clarity.

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 'Transforms a frame into a main component' uses a specific verb and resource, clearly defining the action. It distinguishes from sibling tools like create_component_instance (creates an instance) and create_component_set (creates a set), making the tool's purpose unambiguous.

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 guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites (e.g., frame must exist) or conditions (e.g., nodeName verification). The agent lacks context for appropriate invocation.

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