ARGENTUM

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

With no annotations provided, the description carries the full burden of behavioral disclosure but fails to indicate whether this is a read-only operation, whether results are cached or real-time, or any rate limiting. It mentions 'reputation' as the ranking criteria but lacks safety or operational context.

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 consists of two efficient components: a clear purpose statement followed by parameter documentation. Every word earns its place; the purpose is front-loaded and there is no redundant or boilerplate text.

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?

Given the tool has only one simple parameter and an output schema exists (removing the need to describe return values), the description is minimally adequate. However, with zero annotations and 0% schema coverage, it should ideally disclose the read-only nature of the operation or pagination behavior to be fully 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?

The schema has 0% description coverage (only 'title' and 'type' fields). The description compensates effectively by explaining that 'top' controls 'how many to show' and explicitly stating the default value of 10, providing necessary semantic meaning missing from the structured schema.

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 retrieves a 'karma leaderboard' and specifies it ranks 'top entities by reputation,' providing a specific verb and resource. It implicitly distinguishes from sibling 'get_karma' by focusing on the ranked list aspect, though it doesn't explicitly contrast the two.

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 siblings like 'get_karma' (which likely retrieves specific entity scores) or 'submit_action' (which likely affects karma). There are no prerequisites, conditions, or exclusion criteria mentioned.

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