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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds useful scope binding (a fixed set of exactly three items containing audience/highlights/URL), but says nothing beyond that, and the return shape is already covered by the output schema.

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?

Two sentences, zero filler. The full inventory is front-loaded in the first sentence and the filter behavior follows immediately.

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 single optional enum parameter, complete annotations and an existing output schema, the description supplies everything an agent needs: what the resource is, what it returns conceptually, and how the filter changes the result.

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 coverage is 100% and the enum values are documented inline, so the baseline is 3. The description goes slightly beyond the schema by making the default behavior explicit — omitting kind returns all three offerings — which the schema does not state.

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 ('Lists') and enumerates exactly what is returned — the three eVoost AI offerings (Gravity OS platform, eVoost Services, eVoost Partners network) plus audience, highlights and page URL. This is unmistakable against siblings like get_company_overview or get_faq, which cover different content.

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?

'Pass a kind to get only one of them' tells the agent the optional-parameter path and implies the no-argument path returns all three. There is no explicit when-not or named alternative, but the sibling tools are contextually distinct enough that no routing conflict is likely.

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