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

The annotations already establish read-only, idempotent, non-destructive behavior, and the description is consistent with that safety profile. The description adds useful context about data sources (IMF PortWatch, GDELT, WaveWatch III), but it is truncated and does not explain failure modes, latency, or how the verdict is returned.

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 dense, run-on sentence using excessive capitalization and parenthetical lists, and it cuts off mid-phrase at 'WaveWatch III sea'. It is not cleanly structured or concise.

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 output schema and read-only annotations reduce the burden on the description. It gives a good overview of the chokepoints and data dimensions, but the truncated ending, vague input format, and absence of guidance on targeting a specific chokepoint leave meaningful gaps.

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?

The schema has one parameter, 'input', described generically as 'parametros del producto (JSON o texto)', so schema coverage is 100% and baseline is 3. The description does not clarify how to specify a chokepoint or customize the risk output, so it adds no extra meaning beyond the schema.

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 a clear deliverable: a risk verdict for specific maritime chokepoints based on traffic, narrative, and navigability data. It names the exact chokepoints, which makes the tool's scope understandable, though it does not explicitly differentiate it from related siblings like shipping_alpha.

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 chokepoint risk questions, especially when one of the listed straits is mentioned. However, there is no explicit guidance about when to prefer this tool over alternatives or when not to use it.

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