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

With no annotations, the description must carry the behavioral burden. It does mention the algorithm and robust loss weighting, which is helpful, but it omits crucial behavior such as what the tool returns, convergence behavior, coordinate system assumptions, or limitations. The payment amount is disclosed, but the operational output is not.

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 core behavior is front-loaded in one sentence, with the payment cost appended as a separate concise clause. Every sentence adds relevant information and there is no filler.

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 complex computational tool with no output schema and only an opaque payload string, the description is not complete enough for an agent to invoke it correctly. The agent is left without field-level input guidance, expected return format, or important constraints such as rigid transform assumptions and convergence behavior.

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%, so baseline is 3. The tool description adds that the payload concerns two point clouds, but it still does not explain the expected JSON structure, how the clouds should be encoded, or what parameters are supported beyond the generic payload string.

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 identifies a specific operation: iterative closest point alignment of two unorganized 3D point clouds using a robust Tukey loss weighting. It is distinguishable from the sibling 3D tools, none of which perform ICP registration.

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 implies the tool is for aligning two unorganized point clouds, but it does not specify when to prefer this over alternatives or when not to use it. No sibling comparison or exclusion criteria are provided.

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