get_winning_list

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

No annotations provided, so description must convey behavioral traits. It states 'download' implying read-only, but does not disclose if it consumes tracks, requires authentication, or has side effects. 'Returns the API response' is vague.

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?

Two sentences (15 words) with no wasted words. Starts with the action verb 'Download' and immediately conveys the purpose.

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 simple structure, description lacks information about response format, error conditions, or whether the operation is safe (idempotent, read-only). For a tool with no output schema and no annotations, 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 covers 100% of the single parameter with description. Tool description adds 'for a period (Z34)' which repeats schema context without adding new meaning about the format or usage.

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 specifies 'download winning invoice number list for a period', which is a specific verb and resource. The term 'winning' is slightly ambiguous but contextually likely refers to a lottery or selection. It distinguishes from sibling tools that get general invoice numbers or assign tracks.

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 on when to use this tool versus siblings like get_invoice_numbers, get_assignment_info, etc. No conditions or prerequisites mentioned.

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