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

With no annotations provided, the description carries the behavioral disclosure burden. It does reveal what information the tool exposes, including refusal reasons declared up front and pricing/guarantees, but it never states whether this is a read-only informational call, what the response structure looks like, or whether any side effects exist.

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 compact sentence that lists all key topics with no filler, repetition, or extraneous detail. Every listed item contributes to the agent's understanding of what the tool offers.

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 informational tool, the description is largely complete: it names the main content categories an agent needs to know before invoking it. It could add the return format or explicitly state this is a read-only reference, but invocation itself is trivial, and the listed topics give enough context for selection.

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 has zero parameters, so the baseline of 4 applies. The description does not need to explain parameter meanings, and it does not attempt to; the empty input schema is sufficient.

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 the resource clearly—coverage areas, accepted question and shot types, refusal reasons, pricing, and guarantees—which sets it apart from siblings like check_feasibility or order. However, it lacks an explicit verb such as 'returns' or 'lists,' so it reads as a content label rather than a clear action statement.

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 explicit guidance on when to use this tool versus the sibling tools. The content implies it should be consulted to understand coverage, accepted types, and refusal reasons, but no direct context, exclusions, or alternative-routing cues are given.

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