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

The readOnlyHint annotation already establishes this is a safe read, and the description adds the concrete upstream endpoint 'GET /commissions', which reinforces that. However, it discloses nothing beyond that: no pagination defaults, no ordering, and no note on what an empty result means. Useful but thin against a low annotation bar.

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?

Two compact sentences with the purpose front-loaded and the filter dimensions immediately after. Nothing is padding; the endpoint reference is a single short clause.

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 100% schema coverage and a read-only annotation, the input side is adequately covered. But with no output schema, the description should carry more of the return-value burden and says nothing about the response shape, pagination metadata, or result ordering, leaving a real gap for a 7-parameter list tool.

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?

Schema description coverage is 100%, so every parameter (page, type, status, interval, pageSize, partnerId, customerId) is already documented in the schema, including the interval enum. The description restates the filterable dimensions generically and adds no syntax or format detail beyond the schema, so baseline 3 applies.

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 specific verb and resource: 'List partner commissions'. The filter dimensions (partner, status, customer, time window) sharpen the scope, and the resource is clearly distinct from siblings like dub_list_payouts and dub_list_partners, though it never names an alternative 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 when-to-use or when-not-to-use guidance and no mention of alternatives in the sibling set (e.g. dub_list_payouts, dub_get_partner_analytics). Usage is only implied by the listed filter dimensions, leaving the agent to infer intent.

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