B3.1/5.0

Behavior3/5

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

Annotations already indicate readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false. The description adds that the tool does not infer visibility or safety, which is a useful behavioral constraint beyond the annotations. However, it does not disclose rate limits, authentication needs, or response structure.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is well front-loaded, stating what the tool does and what it does not do. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite having 11 parameters and a complex schema, the description provides almost no contextual guidance. It omits details on required parameters, parameter combinations, output format, or typical usage patterns. The presence of an output schema does not compensate for the lack of usage context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 36%, leaving most parameters undocumented. The description adds no parameter-level information, failing to compensate for the low coverage. The tool lists 11 parameters with no guidance on how to use them effectively.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool finds mapped diving and snorkeling locations and explicitly excludes inferring visibility or safety. It distinguishes from sibling tools like search_swim_spots and search_surf_spots by focusing on diving and snorkeling.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 search_beaches or search_activity_providers. The only hint is 'without inferring visibility or safety', but this does not help an agent choose between related tools.

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