get_top_ranking

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It adds the supported exchanges and the time window, but it does not explain the ordering of results, what fields are returned, how `limit` affects the response, or any rate-limit or error behavior. This is thin for an unannotated tool.

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 single front-loaded sentence that names the resource, the required parameter, and the valid choices. Every word earns its place, and the supported exchanges list is immediately useful.

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 tool is simple with only two parameters, but with no output schema and no annotations, the description does not fully clarify what the returned ranking looks like or whether it is sorted descending by volume. It is adequate for basic invocation but not entirely self-sufficient.

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 already documents both `exchange` and `limit` clearly. The description mostly repeats the exchange options rather than adding new meaning, which matches the baseline score of 3 for full schema coverage.

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 verb ('Fetch'), a concrete resource ('24-hour volume ranking'), and the target context ('for a specified exchange'). It is clearly distinguishable from sibling tools like get_price and compare_prices, which serve different purposes.

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 when to use the tool: whenever the 24-hour volume ranking for one of the supported exchanges is needed. However, it never explicitly contrasts it with get_price, compare_prices, or get_pairs, nor does it mention any exclusions or alternative conditions.

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