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

The annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, and the description merely restates them ('Read-only and safe to repeat; it changes nothing'). It adds no behavioral context beyond the structured data — no mention of rate limits, freshness/staleness, or what the overview actually contains.

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 short sentences with the purpose front-loaded, so it is well-sized and readable. The second sentence is largely redundant with the annotations, so it does not fully earn its place, keeping this just below top marks.

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 no-parameter, read-only informational tool whose annotations already carry the safety profile, the description is nearly sufficient — it names the subject and audience. It falls slightly short by not clarifying its relationship to sibling overview/FAQ tools and not enumerating the topics the overview covers.

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?

There are zero parameters, so the baseline of 4 applies; the schema is trivial and the description need not document any inputs. Nothing about parameter behavior is misrepresented or missing.

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 states a specific subject (the VA International jobs platform) and audience (virtual assistants and employers), clearly conveying that this returns an informational overview. It does not, however, explicitly differentiate itself from close siblings like get_company_overview or get_faq, which an agent could easily confuse with it.

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?

Usage is implied rather than stated: an agent can infer you call this to learn how the platform works, but there is no explicit when-to-use guidance, no indication of when to prefer get_company_overview or get_faq instead, and no prerequisites mentioned.

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