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

No annotations are provided, so the description carries the full disclosure burden. 'Status' strongly implies a read-only, side-effect-free call, and the field enumeration hints at the returned data shape, but there is no explicit statement about read-only semantics, auth requirements, or data freshness.

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?

A single compact sentence that front-loads the resource ('Staking-pool / dividend status') followed by the exposed fields. It is a noun fragment rather than a full sentence, but it wastes no 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?

With no output schema, the description usefully enumerates the returned data points, which is the main thing an agent needs for a zero-parameter getter. Missing only a note on read-only behavior and any 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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline of 4 applies. No misleading parameter information is present.

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 names a specific resource (staking pool / dividend status) and enumerates the exact data it exposes: accrued pool, split shares, vault total weight, undistributed rewards. The verb is only implied by the tool name 'get_pool', but no sibling tool overlaps with this resource, so an agent can distinguish it easily.

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?

There is no statement of when to call this tool, what preconditions apply, or how it relates to alternatives such as get_collection_stats or get_leaderboard. The agent must infer usage purely from the field list.

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