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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds the ranking metric (trading volume), which is useful behavioral context, but it omits the time window defining 'trending', the default result count, and whether results are paginated.

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?

A single front-loaded sentence with zero filler; the resource and ranking basis come first. Nothing is wasted, though the brevity is also the source of the remaining gaps.

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?

With no output schema and no annotations covering scope, the description should say what the trending window is and what the default limit/sort produce. Neither is present, so an agent cannot predict the shape or size of the response.

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 both parameters are documented in the schema and the baseline is 3. The description adds nothing about sort semantics or a sensible default limit, and in fact the schema's own sort wording ('ascending instead of descending') is the only guidance available.

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?

States a specific verb and resource plus the ranking dimension ('assets trending by trading volume'), which is more than a restatement of the name. However, it does nothing to distinguish itself from siblings like get_surging_assets or list_assets, which plausibly return similar data.

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?

No indication of when to use this versus get_surging_assets, list_assets, or get_volume_history. The agent must guess which of several asset-listing tools returns trending data.

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