getTickers

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

No annotations are provided, so the description carries full burden. It discloses that no authentication is required and notes that response fields vary per category. It also specifies the required parameters for options. However, it does not mention rate limits, pagination, or error behavior, but given the read-only nature, this is acceptable.

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 well-structured with bullet points and a summary section. It front-loads the core purpose and is efficient, though there is minor repetition regarding response fields and option conditions. Overall, every sentence adds value.

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 the complexity (4 params, no output schema, many siblings), the description covers purpose, usage guidelines, supported products, and parameter constraints. It lacks details on the 'expDate' parameter and could mention size limits, but it is largely complete for a ticker endpoint.

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 4 parameters with 0% description coverage. The description adds clarity by listing the categories and explaining that for 'option' either symbol or baseCoin must be provided, which is not evident from the schema alone. However, it does not explain the 'expDate' parameter, leaving some semantics incomplete.

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 starts with a specific verb 'Retrieve' and clearly defines the resource as 'latest price snapshot, best bid/ask price, and 24-hour trading statistics across all supported product types.' It lists supported products and distinguishes from sibling tools like getOrderbook and getMarketKline by explicitly stating what not to use this tool for.

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 provides explicit when-to-use scenarios (e.g., 'when you need to: Get the current last traded price...') and includes 'Do not use' instructions with specific alternatives for orderbook depth and historical data. The 'Agent hint' section further reinforces appropriate usage.

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