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

Annotations already declare readOnly, idempotent, non-destructive semantics, so the safety profile is covered. The description adds real value beyond them: results are limited to claimed businesses with booking enabled, and returned times are offers rather than reserved holds, which is a non-obvious behavioral constraint.

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 compact statements front-load the resource, then the parameter constraints, then the offer-not-hold caveat, with no redundant or filler text.

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 output schema and full annotation coverage, the definition supplies what an agent needs: what is returned, the input window constraints, the default, and the non-binding nature of the results. The main omission is guidance on how it relates to the sibling availability/booking tools.

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 0%, so the description carries the full burden and largely does: start/end must be ISO 8601 with offset, must be at most 14 days apart, and default to the next 7 days. Only business_id is left unexplained, though its meaning is self-evident from the name.

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 resource and qualifier: open consultation times for a claimed business with booking enabled. An agent can tell it returns bookable slots rather than services or business details. It does not explicitly contrast with the sibling check_availability, which is the closest competing concept.

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?

The phrase 'with booking on' and the default window imply when this is applicable, and 'Times are offers, not holds' warns about downstream behavior, but there is no explicit when-to-use versus check_availability or book_appointment, and no prerequisites or exclusions stated.

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