is_add_claim_note

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

With no annotations, the description must fully disclose behavioral traits, but it only states the basic action. It does not mention whether the note is appended or overwrites, what happens if the claim does not exist, or any authentication or idempotency details. The description is minimal and leaves the agent uninformed about critical 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?

The description is a single, concise sentence with no wasted words. However, it lacks structure such as bullet points or sections that could improve readability. It is appropriately sized but could benefit from better organization for a tool with multiple parameters.

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?

Given no output schema, the description should explain what the tool returns (e.g., a confirmation or error handling). It does not cover response format, success indicators, or error scenarios. For a mutation tool with moderate complexity, the description is incomplete and leaves gaps in understanding the tool's full behavior.

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 67% (2 of 3 parameters have descriptions). The description adds no additional meaning beyond the schema; it mentions 'adjuster note or status update' which loosely covers note_type but does not explain the enum values. The description does not enhance understanding of parameters beyond 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 uses a specific verb 'Add' and identifies the resource as 'an adjuster note or status update to an existing iSuite claim.' This clearly distinguishes it from sibling tools like is_submit_claim (which submits a new claim) and is_get_claim (which retrieves). The description directly aligns with the note_type enum values, providing a clear purpose.

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?

No guidance is provided on when to use this tool versus alternatives. For example, there is no mention that the claim must exist or that this tool is appropriate for adding notes rather than other operations. The description lacks any contextual cues for selecting this tool among many siblings.

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