C2.9/5.0

Behavior3/5

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

Annotations already establish readOnly, idempotent, openWorld, non-destructive, so the safety profile is covered. The description adds one genuinely useful non-obvious behavior: current conditions are only fetched for the highest-ranked results, which tells the agent that some returned spots will lack conditions. It does not explain what 'ranked' means, what the ranking depends on, or that results may be sparse for narrow queries.

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?

Two short sentences with the purpose front-loaded and the caveat second; nothing is padded or redundant. Brevity here is under-specification rather than verbosity, so the sentence structure itself is fine.

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, zero-required-parameter search tool in a cluster of near-duplicate search siblings, two sentences is far short of sufficient. An agent still cannot tell why to pick this over search_beaches or search_surf_spots, nor how the geo filters interact with the condition filters; the presence of an output schema only relieves the need to describe return values.

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?

With 11 parameters and only 36% schema description coverage, the description needs to compensate and does not: lat, lng, city, limit, radiusKm, intent, maxWindKmh, minWaterTempC, lang, and country get no treatment at all. The only implicit contribution is that the resource-type list loosely informs what the `query` parameter accepts, which is minimal.

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 ('Find') and a concrete resource set (beaches, lakes, bathing places, public swimming locations), so an agent knows the domain immediately. It does not, however, distinguish itself from the closely overlapping siblings search_beaches, search_surf_spots, search_dive_snorkel_spots, or search_river_whitewater_spots, which is the one thing a 'search' tool in this cluster most needs.

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 when-to-use / when-not-to-use guidance and no mention of the alternatives, despite six sibling search_* tools covering adjacent resource types. Nor does it say anything about the city-vs-coordinates choice or which combination of filters is appropriate, leaving the agent to infer everything from the schema.

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