claim_list

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

The annotations already declare readOnlyHint, idempotentHint, and destructiveHint, and the description's 'Read-only' adds no new safety information. It does add useful behavioral context beyond the annotations by stating the newest-first ordering and the recorded-claims scope, though it does not discuss response shape or pagination beyond the schema's limit.

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 one compact sentence with the core purpose front-loaded and includes the key return fields. The structure is slightly marred by the awkward 'status: claim ids from earlier sessions' clause, which is ambiguous.

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 read-only listing tool with two optional parameters and full schema coverage, the description covers ordering, fields, filtering, and read-only nature. The main residual gaps are the ambiguous 'claim ids from earlier sessions' phrase and the lack of any pointer to sibling tools, but these do not block 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 100%, so the schema already documents limit and status semantics. The description adds only a high-level restatement that status filtering is optional, which does not materially extend the schema.

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 identifies a specific resource ('claims') and behavior (newest-first return), and lists the included fields, so an agent can tell it returns a list rather than a single claim. However, it is phrased as a noun fragment rather than an explicit verb and does not name a sibling such as claim_inspect, so it falls just short of full differentiation.

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 guidance on when to choose claim_list over claim_inspect or other siblings, and no exclusions or alternative routing are given. The phrase 'optionally filtered by status' only describes a parameter, not a selection context.

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