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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds the useful fact that outreach happens via WhatsApp or email, but the second sentence about the concierge is promotional rather than behavioral, and nothing is said about response expectations.

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?

The primary sentence is front-loaded and efficient, but the trailing sentence about the Dubai Table concierge does not help an agent decide whether or how to call this tool, and 'these venues' is vague without prior context.

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?

With no parameters, an output schema to cover return values, and complete annotations, the description supplies what is needed: the escalation scenarios and the contact channels. Only the dangling venue reference keeps it from being fully self-contained.

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 tool takes zero parameters, so the baseline is 4 and there is nothing parameter-related for the description to compensate for.

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 action (contacting a relationship manager) and the concrete channels (WhatsApp or email), which clearly separates it from the booking-oriented siblings like request_table or show_tables. It stops short of explicitly naming a sibling alternative, 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?

Gives a clear use condition: large groups, special arrangements, or anything outside the listed venues. It does not state when *not* to use it or route the agent to a named alternative, and the phrase 'these venues' is a dangling reference with no antecedent in the description.

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