get_trending_crypto

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

With no annotations, the description must carry full behavioral disclosure. It only mentions the $0.001 per request cost, which is useful, but it does not describe what the response contains, whether results are sorted, rate limits, or any side effects. This incomplete disclosure leaves the agent guessing about the tool's behavior.

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 extremely concise: one short sentence for the purpose and one for the cost. Every word earns its place, and the format is front-loaded.

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?

Given no output schema and no parameter schema, the description must explain what the generated response looks like, but it does not. An agent would not know whether the result is a list of symbols, names, or objects with prices. The tool is simple, but the description is incomplete for effective 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?

The tool has zero parameters and the schema coverage is 100% trivially. The description appropriately avoids adding parameter details, so the baseline of 4 applies.

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 'Get trending cryptocurrencies' is essentially a restatement of the tool name 'get_trending_crypto' with no additional scope or distinguishing details. It does not differentiate from sibling tools like 'get_crypto_markets' or 'search_crypto', making it minimally informative.

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 guidance is provided on when to use this tool versus alternatives such as 'search_crypto' or 'get_crypto_markets'. The description implies a use case for trending data but explicitly lacks any when-to-use or when-not-to-use context.

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