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

The annotations already declare readOnlyHint=true and openWorldHint=false, so the agent knows this is a safe, self-contained read. The description adds the useful context of what data the catalogue exposes (prices, terms, references, contact), but says nothing about result size, pagination, or whether the catalogue is static or per-request.

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?

One compact sentence-fragment that front-loads the resource name and then lists contents in priority order. Nothing is wasted, though the fragmentary style means it reads more like a label than an instruction.

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 simple, read-only, one-optional-parameter tool with annotations covering the safety profile, the content overview is close to sufficient. It falls short by omitting the language parameter and any hint of the return shape or catalogue size.

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 single parameter 'lang' has 0% schema description coverage and an enum of en/cs, yet the description never mentions language selection at all. With schema coverage this low, the description is expected to compensate for the undocumented parameter and does not.

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 names a specific resource (ROBOTio catalogue of humanoid robots for rent with operators) and enumerates the contents an agent can expect: event use cases, starting prices, terms, references and contact. It's a noun phrase rather than a verb+resource, and it never explicitly contrasts itself with siblings, but the purpose is unambiguous.

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 when-to-use guidance and no mention of the sibling tools check_availability or request_quote, which are the obvious alternatives once a visitor has seen the catalogue. An agent must infer that this is the browsing/overview step rather than the booking or pricing-request step.

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