Resolve Minecraft Player

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

No annotations provided, so description carries full burden. It mentions 'normalized UUID forms' but does not disclose behavior for invalid inputs, parameter priority if both uuid and username are provided, or any error handling. Minimal insight into side effects or return structure.

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?

Single sentence, front-loaded with purpose, zero waste. Every word earns its place.

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?

Despite simplicity, description lacks critical context: parameter precedence, output format, validation behavior, and whether it involves network calls. No output schema to supplement. Incomplete for a resolver tool with two optional parameters.

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 has 100% coverage, already describing both parameters clearly. The description adds value by stating overall purpose but does not elaborate on parameter semantics beyond what schema provides. Baseline 3 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?

Description clearly states the action 'Resolve', the resource 'Minecraft username or UUID', and the purpose 'into normalized UUID forms for Hypixel tools'. This distinguishes it from sibling tools like hypixel_player which retrieves player data.

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 phrase 'for Hypixel tools' implies usage as a prerequisite before other Hypixel tools, but there is no explicit guidance on when to use versus alternatives, nor when-not-to-use conditions.

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