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

Annotations already establish readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false. The description adds only that filters are optional; it says nothing about return shape, pagination, default scope, or what happens when no filters are supplied, so it adds little behavioral context beyond the annotations.

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 short and front-loads the resource and filters, but it is a sentence fragment rather than a well-structured statement. The 'for example BNK' example is marginal while more important details are omitted.

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 list tool with three optional parameters and no output schema, the description is still too skeletal. It does not state that all claims are returned when filters are omitted, does not explain the enum-backed filters, and gives no sense of the result set, making it incomplete 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?

Schema description coverage is only 33%, so the description should compensate by explaining status and source_type, but it merely names them. It does not clarify the meaning of the enum values for status or source_type, and the prefix example duplicates what the schema already provides.

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 the resource ('Claims') and the optional filters, but it is a noun-phrase fragment with no explicit verb such as 'list' or 'retrieve'. It implies a listing operation, yet an agent must rely on the tool name and title to confirm the action rather than the description itself.

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?

It mentions that filtering is optional, which gives minimal hint about how to narrow results, but it never says when to use this tool instead of alternatives such as get_claim. No conditions, exclusions, or sibling routing are provided.

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