Whiteout Survival State Transfer tracker: phase dates, active status, remaining pass chances.
Scored across 1 tool
With only one tool, there is no ambiguity between tools. The single tool has a clearly defined purpose.
The single tool name follows a clear descriptive verb_noun pattern (get_upcoming_state_transfer), which is consistent within the set.
One tool is borderline: it may be appropriate for a very narrow domain, but generally a single tool feels thin for a server.
The tool provides comprehensive information for the stated domain of state transfer tracking, including all relevant dates, active status, and shop chances.
Returns the current or next upcoming State Transfer event for Whiteout Survival: dates for the three transfer phases (power cap setup, invitations, transfer passes), whether the transfer is currently active, and how many weekly chances remain to buy a Transfer Pass from the Alliance Shop before the transfer date. Dates are in UTC, formatted as "Year/Month/Day" (e.g. "2026/07/19"). transferDate is a "Month Year" label identifying the transfer window (e.g. "July 2026").

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It explains the output in detail: dates in specific format, timezone (UTC), what each field represents, and the scope (current/next upcoming). It does not mention side effects or auth needs, but for a read-only getter, this is sufficient.
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 concise yet comprehensive. Every sentence adds necessary detail about the output fields, format, and timezone. It is front-loaded with the core purpose and uses efficient, direct language without 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?
Given the tool has no parameters and no output schema, the description fully compensates by listing all return values, their meanings, and format details. It is complete for an agent to understand exactly what the tool returns and how to interpret the data.
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?
There are zero parameters, so the input schema is empty. The description does not need to explain parameters. It adds value by describing the output that corresponds to the implicit no-parameter call. Baseline 4 is appropriate.
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 returns the upcoming State Transfer event for a specific game, listing all returned elements (dates, phases, active status, weekly chances). It uses a specific verb ('Returns') and resource ('State Transfer event'), and the description is unique enough to distinguish it from any potential siblings (none provided).
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 does not explicitly state when to use this tool versus alternatives, nor are there any siblings or exclusion conditions mentioned. However, the purpose is clear and usage is implied for retrieving transfer event details. It lacks guidance on when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
