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

Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds valuable behavioral context beyond that: it does NOT return a verdict, only normalized facts and attention signals, and the decision remains with the user. This is a critical safety-relevant nuance for an agent setting expectations. No contradiction with annotations.

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?

Two sentences with no filler: the first front-loads the aggregation use case and scope, the second adds the essential non-verdict caveat. Every clause earns its place and the structure is easy to scan.

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 description adequately covers what the tool aggregates, what it returns, and what it deliberately does not do. The presence of an output schema handles return-value details, and the openWorldHint covers data variability. The only minor gap is explicit guidance on when to use sibling tools instead, but overall the description is complete enough for correct invocation.

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 100%, so the schema fully documents all five parameters. The description only frames the core inputs ('sentiero' and 'data') at a high level without adding syntax, defaults, or new meaning to any parameter. Baseline 3 is appropriate.

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 specific action ('raccoglie in un colpo solo') and enumerates the exact resources it aggregates: trail data, nearby refuges/bivouacs, avalanche bulletin, and mountain weather. It also differentiates itself from the individual sibling tools by being a one-shot aggregation, and clarifies the output is normalized facts and attention signals, not a go/no-go verdict.

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 a clear context for use ('Dato un sentiero e una data') and the convenience of a one-shot collection, but it does not explicitly name alternatives like dettaglio_sentiero or bollettino_valanghe, nor state when to use those instead. No exclusions or when-not-to-use guidance is provided, so the routing is left to inference.

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