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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered; the description adds genuinely new behavior beyond that by specifying sort order ('newest first') and result contents ('status and report links'). It does not disclose pagination behavior despite the limit cap of 50.

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?

One tightly written sentence with the operation, scope, ordering, and payload all front-loaded. No filler or redundancy.

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 simple two-parameter read tool with no output schema, the description covers what is returned and in what order, which is helpful. However, it omits any mention of the status filter or page-size limit that are its only two knobs, leaving an agent to discover them solely from the schema.

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 only 50% (the status enum has no per-value explanation and limit is a bare 'Default 10'), and the description adds nothing about either parameter. It never says results can be filtered by status or bounded by limit, so it fails to compensate for the coverage gap.

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 ('Lists'), a precise resource ('income verification requests'), and scope ('the signed-in user's'), which separates it from write siblings like send_verification_request and start_income_verification. It stops short of naming a specific sibling to avoid, so it lands just below the top band.

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 read-only framing and 'signed-in user's' scope imply the retrieval use case, but there is no explicit statement of when to call this versus checking a single request or starting a new one. No exclusions or prerequisites are given.

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