get_pricing

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

No annotations are provided, so the description carries the full burden. It discloses the call is free and returns specific fields (x402 wallet address, network, USDC contract, price in USDC). This gives good behavioral context, though it doesn't mention authentication or rate limits, which are likely unnecessary for a free, parameterless call.

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?

Three sentences with no wasted words. First sentence states purpose, second details output, third gives usage guidance. It is appropriately sized and 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 zero parameters and the existence of an output schema (though not shown), the description mentions what the call returns and explains when to use it. It covers the necessary context for a simple tool.

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?

There are no parameters, and schema coverage is 100%, so baseline is 4. The description adds no extra parameter info because none exist, but that's 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?

Description clearly states the tool fetches current per-endpoint pricing for koreafilings.com. The verb 'Fetch' and resource 'current per-endpoint pricing' are specific. Sibling tools are about filings and disclosures, so this tool is distinct.

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?

Description explicitly notes it's a free call and useful for confirming the payer will settle on the expected chain before spending. This implies when to use it, though it doesn't provide explicit exclusions or alternatives. Nevertheless, the context is clear.

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