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 does not state whether the call is read-only, what side effects exist, or any rate limits. For a simple leaderboard lookup, the agent assumes safety, but nothing explicitly discloses 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 a single, compact sentence that gets straight to the point. It is front-loaded with the core purpose and contains no superfluous words.

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 is simple (one parameter, no output schema), but the description omits critical details: what fields the leaderboard entries contain, how the limit parameter affects the result, and any default behavior. For a tool with no annotations or output schema, more context is needed for correct invocation.

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?

The single parameter 'limit' is described only in the schema with a default and max, but the tool description mentions it not at all. Since schema description coverage is 0%, the description fails to add any meaning or usage context for the parameter, leaving the agent with minimal guidance on how to use it.

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 resource (leaderboard of top traders on X1) and the ranking criteria (realized PnL + win-rate). It is specific and informative about what the tool returns, though it does not explicitly distinguish it from sibling tools that might also provide rankings (e.g., graviton_top_bettors).

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 on when to use this tool versus related tools like graviton_top_bettors or recent_trades. The description does not mention scenarios or exclusions, leaving the agent to infer usage from the resource name alone.

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