get_events_on_day

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

No annotations are provided, so the description carries the disclosure burden. It does signal that this is a read/query of game calendar data and enumerates the categories of events returned, which is useful, but it says nothing about ordering, empty results, or scope limits beyond the stated season/day.

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?

A single front-loaded sentence with the action first and the returned event categories parenthetically listed. No filler or redundancy.

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?

For a two-parameter read-only lookup with an output schema, the description is nearly sufficient: it names the resource, scope, and returned categories. It stops short of full marks only because it does not differentiate itself from the calendar siblings that overlap in purpose.

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 50%: 'day' is documented (1-28) and 'season' is an enum. The description only restates that a season and date are supplied, adding no format or constraint detail beyond the schema. Baseline 3 is appropriate since the schema covers most of the semantics.

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?

States a specific verb (查询/query) and resource (events on a day), and enumerates the event categories returned (festivals, passive festivals, fishing derby, bookseller, birthdays). This clearly distinguishes it from a plain birthday lookup, though it does not explicitly name the sibling get_todays_events or get_birthdays_on_day to route the agent.

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?

There is no when-to-use guidance and no mention of alternatives. With siblings like get_todays_events and get_birthdays_on_day, the description should clarify that this tool takes an arbitrary season+day rather than only the current date, but it leaves that inference to the agent.

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