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

There are no annotations to provide safety information, and the description does not disclose whether this is a read operation, requires authentication, or has any side effects. Saying 'Your profile, rating and record' only names the data, not the behavior.

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 short and trivial, but it is so sparse that it borders on under-specification rather than effective conciseness. It is not bloated, but it also does not earn its place by adding meaningful operational detail.

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 one required parameter, no annotations, and no output schema, the description could still have been complete with a simple action verb and parameter explanation. Instead it provides only a vague noun phrase, leaving key contextual details for the agent to guess.

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 0%, and the description does not mention the required token parameter or explain its purpose. The agent is left to infer what the token is and how it should be used.

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 identifies the resource as the user's profile, rating, and record, which distinguishes it from siblings like leaderboard. However, there is no verb indicating whether the tool retrieves, updates, or deletes this data. The intent is inferred rather than explicit.

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?

No guidance is provided about when to use this tool instead of siblings such as leaderboard or observe. The description gives no context, prerequisites, or alternative tool recommendations.

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