getWorldRoutePlayerCount

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It states the tool gets counts but does not disclose whether it is read-only, requires authentication, or what the response structure looks like. It also fails to mention potential side effects or data source characteristics. Minimal behavioral information is provided.

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 concise sentence with no redundancy or filler. It conveys the necessary information efficiently, which is appropriate for the tool's simplicity.

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?

The tool has no parameters and no output schema, so the description is the primary source of information. It covers the core function but omits expected response format, data source, and operational details like how 'current' is defined or whether authentication is needed. These gaps are significant for an agent relying solely on the description.

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 in the schema, so the description has nothing to explain regarding parameters. The baseline for zero parameters is 4, and the description's explanation of the tool's purpose is clear, even though it adds no parameter-specific details.

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's purpose: 'Get current player and bot counts per world and route.' This uses a specific verb ('Get') and identifies the exact resource (player/bot counts) and scope (per world and route). It distinguishes itself from sibling tools like getRoutes or getPlayerData by focusing on counts, and the name aligns with the description.

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 provides no guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites. While the name implies a read-only query for current counts, there is no explicit context about use cases or comparison with other tools. The usage is implied but not articulated.

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