boolean_operation

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

Annotations already indicate readOnlyHint=false and destructiveHint=true, so the agent knows the tool mutates and is destructive. However, the description adds no extra behavioral context, such as which object is modified, whether the target_object is consumed, or how the operation handles failure cases. It merely restates the operation type.

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 very concise, a single sentence that immediately conveys the core purpose. It is front-loaded and avoids unnecessary verbosity. However, it sacrifices completeness for brevity, omitting parameter and usage details, but that is not a fault of structure or conciseness.

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 tool has moderate complexity (binary mesh operation with order-sensitive parameters) and a 0% schema coverage. An output schema exists, so return values are covered, but the description fails to explain parameter roles, operation semantics, or prerequisites. This makes the definition incomplete for correct invocation, especially since boolean operations require understanding which mesh is the base and which is the target.

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 0% and the description does not explain the parameters at all. Specifically, it does not clarify the distinction between object_name and target_object (which is critical for DIFFERENCE where order matters), nor does it list the possible operation values beyond the default. The agent has to guess parameter semantics, making this a significant gap.

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 indicates a Boolean operation (DIFFERENCE/UNION/INTERSECT) on two meshes, which is specific and distinguishes it from sibling mesh-editing tools such as join_objects or merge_by_distance. However, it lacks an explicit verb like 'perform' or 'compute', making it a noun phrase rather than a full command statement.

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, nor does it mention prerequisites (e.g., both objects must be meshes) or the destructive nature of the operation. It only states what the operation is, leaving the agent to infer usage context.

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