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

Annotations already declare this is a safe read (readOnlyHint=true), so the safety profile is covered. The description adds what the response contains (current slip, rollup counts, long-term median rollups), which is useful given no output schema, but it discloses no pagination, format, or error 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?

Three sentences, front-loaded with the verb and resource, then scope, then definitional context. The third sentence earns its place by naming the returned fields, though 'Pool slip measures trading activity and depth pressure' is somewhat ancillary.

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 parameterless read-only list with no output schema, the description covers scope and return content adequately. The main gap is that 'Layer 1 pools' and the result format go undefined, but the overall coverage is sufficient 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 tool takes zero parameters, so per the rubric the baseline is 4. Schema coverage is 100% and there are no arguments whose semantics need explaining.

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?

States a clear verb ('Returns'), resource ('pool slip information'), and scope ('all Layer 1 pools'), which implicitly distinguishes it from the singular sibling get_pool_slip. It also defines what pool slip measures. Sibling differentiation is present but not named explicitly.

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 explicit when-to-use or when-not guidance, and no named alternative (e.g. get_pool_slip for a single pool). The mention of 'fee calculations and pool health monitoring' hints at a use context but does not route the agent between this tool and its siblings.

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