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

With no annotations at all, the description carries the full burden. It does disclose the content posture ('neutral overview'), signaling this is informational and non-advisory rather than a personalized or transactional result, but it says nothing about the return shape (static text, enumerated stages, jurisdiction-specific caveats) or whether the content is fixed.

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?

A single short sentence with the resource front-loaded and no filler. It is efficient, though the parenthetical '(neutral overview)' is doing the only differentiation work and could be folded into a stronger 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?

For a zero-parameter, no-annotation, no-output-schema tool, the definition is minimally viable: an agent knows what it will get at a high level. It stops short of describing what the explanation contains or how it is framed, which is the one piece of context that would make the tool unambiguously callable without trial.

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?

The tool takes zero parameters, so there is no parameter semantics to explain and the baseline of 4 applies. The description correctly implies a parameterless, general-purpose call.

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: explains the insurance appraisal process, with a qualifier that the content is a neutral overview. This is clearly distinct from the sibling lookup tools (get_appraiser_profile, search_appraisers), though the description never names them 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?

No guidance on when an agent should call this versus the sibling tools, or what kind of user question it answers (e.g., 'how does appraisal work?' vs 'who is my appraiser?'). Usage is only inferable from the name and the word 'overview'.

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