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

With no annotations provided, the description carries the full burden of behavioral disclosure, yet it only lists operation types and does not mention side effects, return behavior, or computational assumptions. For a likely pure computation tool, the lack of any statement about read-only or stateless nature is a gap.

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, information-dense sentence that front-loads the domain. Every word contributes to clarifying the tool's scope, with no padding or repetition.

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?

While the output schema exists to explain return values and the input schema covers parameters, the description is minimal and relies heavily on schema. It provides domain context but omits usage scenarios, behavioral notes, or edge-case hints, making it adequate but not fully complete for an agent's decision-making.

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 both 'operation' and 'points' clearly described. The tool description adds no extra parameter meaning beyond the schema, as it merely repeats the operation list. Baseline 3 is appropriate given schema's thoroughness.

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 states the tool's domain (geometry) and specific functions (distances, areas, volumes, convex hulls), making it distinct from sibling tools like matrix_operation or vector_calculus_operation. While it lacks an explicit verb like 'calculate', the enumerations of operations clearly convey purpose.

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 usage for geometry computations on points and polytopes but gives no explicit guidance on when to prefer this over alternatives or any exclusions. Sibling tools exist for other domains, but no direct comparison is made.

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