C2.9/5.0

Behavior3/5

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

Annotations already declare readOnly, idempotent, non-destructive and open-world, so the safety profile is covered. The description adds one genuinely useful behavioral constraint not in annotations: results must not be treated as evidence of visibility or safety. It says nothing about result limits, ranking, or coverage gaps.

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

Conciseness4/5

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

A single tight sentence with no filler, and the core purpose is front-loaded before the caveat. The trailing clause is compressed to the point of being slightly cryptic ('without inferring visibility or safety').

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?

For an 11-parameter geo search with wind and water-temperature filters plus an output schema, one sentence is thin. The description never explains that conditions-related filters exist or how they relate to the caveat that visibility/safety are not inferred, leaving an agent to reverse-engineer the tool's limits from the schema.

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

Parameters2/5

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

Schema description coverage is only 36% across 11 parameters, and the description mentions none of them. Ambiguous parameters such as intent, maxWindKmh and minWaterTempC are left entirely to a partially-documented schema, and the interaction between those condition filters and the 'no safety inference' warning is unexplained.

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

Purpose4/5

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

States a specific verb+resource ('Find mapped diving and snorkeling locations') that clearly separates it from siblings like search_beaches, search_swim_spots and search_surf_spots. The added clause 'without inferring visibility or safety' scopes the result type but is a caveat rather than a sibling comparison.

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?

There is no explicit when-to-use or when-not-to-use statement, and no alternative is named. The caveat about visibility/safety only hints that get_spot_conditions or get_community_conditions exist; the agent must infer that routing itself.

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