Get Hypixel Player Status

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description usefully adds the API-key requirement and implies external network dependency, but says nothing about rate limits, failure behavior for unknown players, or response shape.

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 naming the resource and its contents, followed immediately by the auth prerequisite. No padding 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?

With no output schema, the field enumeration (status, rank, login times, karma, stats) usefully sets return-value expectations, and annotations carry the safety semantics. Only the vague phrase 'selected network stats' and the absent sibling routing keep it short of complete.

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 100% and both parameters (uuid, username) carry their own descriptions including the dashed/undashed format. The description adds no parameter-level detail, which is the expected baseline 3 when the schema does that work.

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?

Specific verb (Fetch) plus resource (Hypixel network player data) with an explicit enumeration of returned fields (online status, rank, login times, karma, network stats). This lets an agent distinguish it from generic player endpoints, though it never names resolve_player or explains how the two divide labor.

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 only guidance is the prerequisite 'Requires HYPIXEL_API_KEY'. There is no statement of when to call this versus resolve_player, nor whether uuid or username should be supplied, so the agent must infer routing from the schema.

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