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

Annotations already declare this as a safe, idempotent, non-destructive read. The description adds useful context by naming the contact channels (WhatsApp or email), but reveals nothing further about response content, availability, or authentication. With annotations carrying the safety burden, a 3 is appropriate.

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 first sentence is front-loaded and useful. The trailing sentence about the concierge arranging tables across Dubai reads as promotional context that adds little decision value, so the description is slightly padded.

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 an output schema present, return-value details need not be described, and zero parameters mean no schema gaps. The description covers purpose and call conditions, leaving it essentially complete for a contact/escalation tool.

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 and the schema is trivially complete, so there is nothing for the description to compensate for. Baseline 4 applies.

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 outcome: reaching a relationship manager at Dubai Table via WhatsApp or email, and scopes it to cases 'outside these venues, large groups, or special arrangements.' This clearly separates it from the booking-oriented siblings like request_table and list_venues, though it doesn't name a specific sibling.

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 explicit trigger conditions (large groups, special arrangements, anything outside the covered venues), which is clear escalation guidance. It stops short of naming the alternative tools or stating when NOT to use it, but the implied routing is understandable.

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