get_set_statistics

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

With no annotations provided, the description carries full behavioral disclosure burden. It adds only the USD/EUR separation detail, but does not disclose what 'statistics' encompass, what the output format is, whether it's a read operation, or any performance/caching/pagination constraints. Very thin for a tool with no annotation coverage.

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 short sentence with no filler words. Every word earns its place, though it could be criticized for being under-specified rather than concise. Still, brevity itself is handled well.

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?

Despite having an output schema and 2 parameters, the description is inadequate for a tool with 0% schema coverage and no annotations. It doesn't clarify the statistics semantics, the set code/id format, the cardmarket_variant parameter, or how this differs from get_set_prices and get_set_completion_value. For a tool nested among many similar set-related siblings, more context is needed.

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 0%, meaning the description must compensate for both parameters. The description provides zero explanation of what set_code_or_id should look like (code format vs. ID format) or what cardmarket_variant accepts. Both parameters are left entirely to the reader despite 0% 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 verb 'get' plus resource 'set statistics' is somewhat specific, offering some clarity about what is being retrieved. However, it doesn't distinguish from the many sibling set tools like get_set, get_set_prices, get_set_cards, or get_set_completion_value, and the meaning of 'Pro set statistics' is ambiguous.

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 notes that USD and EUR remain separate, giving a minor hint about data structure, but offers no guidance on when to use this vs. sibling set tools (get_set, get_set_prices, get_set_completion_value). No when/when-not context or alternatives are named.

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