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

Annotations already declare this as a safe read (readOnlyHint=true, destructiveHint=false), so the bar is lower. The description adds real value beyond that: the return fields, the fact that requests expire two business days after receipt, and the auth requirement (Cotlet API key with app access).

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?

Purpose is front-loaded and the downstream routing is useful, but the first two sentences overlap heavily, restating that it lists bookings and requests and re-listing the same fields. That redundancy costs some efficiency.

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 read-only list tool with annotations and no output schema, the description covers what is returned, the expiry semantics for requests, the auth requirement, and downstream usage. Adequate and mostly complete.

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 100%, so the filters (to, from, cursor, status, listing_id) are already documented. The description adds no syntax or format detail for these parameters, so the baseline 3 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 verb (lists) and resource (booking requests and bookings from the Bookings tab), and enumerates the fields returned (guest first name, start/end, attendees, status). An agent can distinguish this browse tool from the singular get_booking and the action tools accept/decline without opening the 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?

Explicitly names the downstream alternatives that consume booking_id (get_booking, accept_booking_request, decline_booking_request), which clarifies when this list is the entry point. It does not spell out a when-not condition, but the routing context is clear.

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