BIS Statistics Query

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

Annotations already provide readOnly, idempotent, and openWorld hints. The description reinforces these by stating 'completely free, no authentication needed' and adds that multiple countries can be queried simultaneously. No contradictions, and it provides useful behavioral context beyond annotations.

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 concise and front-loaded with the main purpose, followed by a structured Args list. However, it fails to include the 'key' parameter in that list, which is an omission that harms completeness without being overly verbose.

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 5 parameters (1 required), no output schema, and good annotations, the description covers the core functionality and free/no-auth context. However, the missing 'key' parameter and lack of detail on pagination or date format prevent it from being fully complete for an agent.

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 coverage is 100%, so baseline is 3. The description explains most parameters with examples, defaults, and preset datasets. However, it omits the 'key' parameter entirely, which is present in the schema but not mentioned in the Args list, slightly reducing comprehensiveness.

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 clearly states the tool queries BIS statistics, lists specific indicators (effective exchange rates, credit gaps, etc.), and mentions multi-country support. It distinguishes from sibling tools by explicitly naming 'BIS' versus other data sources like IMF, World Bank, etc.

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 use for BIS data via its name and domain, and adds context that it is free and requires no authentication. However, it does not explicitly state when not to use it or name alternative tools for other data sources, though the sibling list makes this implicit.

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