get_contributor_network_item_benchmark

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

No annotations are provided, and the description only states the purpose and scope. It does not disclose idempotency, error behavior, rate limits, or what the 'breakdown' entails, leaving significant behavioral uncertainty.

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 very concise, consisting of two short sentences. It is front-loaded with the functional purpose. However, it could be expanded slightly to add missing context without becoming verbose.

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 no output schema and no parameter descriptions, the description fails to explain what the 'per-model benchmark breakdown' returns (e.g., metrics, scores). It lacks completeness for an agent to understand the tool's output and usage context.

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?

With 0% schema description coverage, the description adds no meaning to the single required parameter 'item_id'. It does not explain what constitutes an item ID, where to obtain it, or any constraints beyond type string.

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 'Get the per-model benchmark breakdown for one item,' using a specific verb and resource. It distinguishes from siblings like 'list_contributor_network_benchmarks' (list vs get) and 'get_contributor_network_item' (item details vs breakdown).

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 explicit guidance on when to use this tool versus alternatives. The scope note 'contributor-network.read' is minimal and does not help choose between this and related tools like 'list_contributor_network_benchmarks' or 'get_contributor_network_item_graph'.

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