get_holiday_stats

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

No annotations are provided, so the description carries full responsibility. It only states the function without disclosing behavioral traits like return format, aggregation details, or potential limitations (e.g., date boundaries). This is a significant gap.

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, clear sentence that front-loads the verb and resource, with no unnecessary words. It is appropriately concise for a simple tool.

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?

With no output schema and no annotations, the description omits what 'statistics' means or what the response contains. For a tool with two parameters, this is under-specified and leaves the agent guessing about the return value.

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 input schema covers 100% of parameters, with year and month each having descriptions. The description adds minimal semantic value, only reaffirming that the tool works for a year or year-month combination, which is already implied by the parameters.

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 retrieves Taiwan holiday statistics for a specified year or year-month, using a specific verb (獲取) and resource (台灣假期統計資訊). However, it does not explicitly differentiate from sibling tools like check_holiday or get_holidays_in_range, though the 'statistics' focus implies a different use case.

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 implicitly conveys usage: use when you need Taiwan holiday statistics for a year or month. It lacks explicit guidance on when to prefer this tool over siblings, such as when checking a single date or a range.

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