get_week_birthdays

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

No annotations exist, so the description must carry behavioral disclosure. It states the default filtering behavior (include_past=false returns today and later), which is useful, but it does not mention read-only nature, permissions, or error behavior.

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 plus a compact Args section. Purpose is front-loaded and there is no redundant text.

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 the low complexity (one boolean parameter) and the presence of an output schema, the description provides everything needed to call the tool: purpose, scope, and parameter behavior. No critical gaps.

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%, so the description must explain include_past. It does: 是否包含本周已经过去的日子，默认只返回今天及之后. This fully clarifies the parameter's semantics and default behavior.

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 states a specific verb (获取) and resource (本周村民生日列表), and defines the week scope (游戏内周，周一到周日), which inherently differentiates it from day- or month-scoped siblings like get_birthdays_on_day and get_month_calendar.

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 gives clear context (this week's birthdays, default excludes past days) but does not explicitly name alternatives or state when not to use it. Usage is implied from the scope, not spelled out.

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