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

No annotations are provided, so the description carries the full burden. It discloses the API key requirement and hints at the response content by listing the statistics covered, but it does not explicitly confirm the operation is read-only or mention potential limitations such as rate limits or the scope (all pools vs a specific pool). This is adequate but not rich.

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, front-loaded sentence that efficiently captures the tool's purpose and lists the key statistics returned. There is no redundancy or unnecessary detail, making it highly concise and well-structured.

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?

For a no-argument stats endpoint, the description covers the main purpose and the categories of output data. However, without an output schema or additional behavioral detail, the agent may not know the exact response shape or whether the stats are aggregate across all pools or filtered. Still, it is largely sufficient for a straightforward read operation.

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 tool has zero parameters, and the schema is empty. According to the rubric, a zero-parameter tool receives a baseline score of 4, as there are no parameter semantics to explain. The description adds no parameter-specific meaning, which is appropriate given there are none.

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 that the tool retrieves comprehensive statistics for energy/bandwidth pools, enumerating delegations, revenue, utilization, and APY. This distinguishes it from sibling tools like get_pool_delegations and get_earnings, which are single-purpose, making the purpose explicit and specific.

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 implies the tool is used to obtain an all-in-one view of pool statistics, but it does not explicitly state when to use it instead of more specific sibling tools like get_pool_delegations or get_earnings. There is no explicit when/when-not guidance or mention of alternatives, only the inferred 'comprehensive' nature.

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