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

Annotations mark this as a non-read-only, open-world, non-idempotent call; the description usefully adds the outbound channel and latency (sales replies by email, usually within one business day), which the annotations cannot convey. It does not warn that repeat submissions would generate duplicate inquiries despite idempotentHint=false, nor describe what the caller sees on success — a modest gap for a write tool with no 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 tight sentences with the purpose first and the gating condition second; nothing is redundant. The parenthetical enumeration of inquiry types is slightly dense but earns its place by scoping what qualifies as a quote request.

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 10-parameter write tool with no output schema, the description covers the essential gating rule, destination and turnaround but leaves the agent unsure how optional fields (budget, timeline, country) should be gathered and what confirmation or reference the user receives. Adequate to avoid misuse, not complete enough to drive a fully informed collection flow.

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 only 40% across 10 parameters, so the description should carry more weight. It does add real meaning by constraining name, email and organization to the user's own details, but it says nothing about budget, country, timeline, or the products quantity field, leaving over half the surface undocumented in either place.

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 gives a specific verb and resource — submit an inquiry (hardware, volume pricing, dataset licenses, data services) to the VisionLibra sales team — so the agent knows exactly what the tool does. It doesn't explicitly name the read-only siblings (search_products, search_datasets, get_product_specs) to contrast against, but the submission purpose is unmistakably distinct from them.

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?

It states an explicit precondition set: only call when the user has asked for a quote AND supplied their own name, email and organization. That is both a when-to-use rule and an implicit when-not-to-use rule, which is exactly what an agent needs to avoid premature or hallucinated invocations.

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