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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=true, so the outside-world send is known. The description adds meaningful context the annotations do not: the consent-gated workflow, the 24-hour e-mail reply, and the non-binding nature. It stops short of stating whether the request can be retracted or duplicated, which is the only remaining gap.

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?

Three short sentences, front-loaded with the action and its destination, followed by the consent requirement and the non-binding caveat. Every sentence carries distinct information with no repetition.

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 16-parameter, low-coverage, no-output-schema tool, the description covers the consent and safety context well but leaves the parameter surface largely unexplained. An agent would still have to infer what most fields should contain, so it is adequate but incomplete.

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 38% across 16 parameters, so the description would need to compensate. It mentions only name and e-mail in passing and explains nothing about event_date format, robots limits, wants_show constraints, language, or the agent/venue/guests fields – leaving most parameters undocumented in both places.

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 and resource ('Send a quote request to ROBOTio') and immediately clarifies the nature of the action ('non-binding request, not a booking'), which separates it from a booking tool. An agent can tell this apart from check_availability and get_catalog without opening a schema.

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?

Gives an explicit pre-condition workflow: show the user a summary and send only after explicit agreement to share name and e-mail. It also states the expected response channel and latency (e-mail within 24 hours), so the agent knows when this tool is appropriate and what to expect.

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