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

With no annotations provided, the description carries the full burden, and it discloses the substantive response content (contract position, ABTOT bonding, ATOL relevance) plus the implicit read-only nature via 'Get'. It does not address auth requirements or error behavior, which keeps it below 5 for a total-annotation-vacuum tool.

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?

Two front-loaded sentences with zero waste: the first establishes what is returned, the second enumerates retrieval triggers. Every clause earns its place.

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 0-parameter getter with no output schema and no annotations, the description supplies exactly what an agent needs: the object retrieved and the questions it answers. Nothing required to invoke it correctly is missing.

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 0 parameters, so the baseline is 4. There is nothing for the description to clarify beyond what the empty schema already conveys.

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 (Get) and a precise resource (Follow On Tours' financial protection statement and its position in the contract), including the substantive fact that it is the tour operator and package organiser bonded through ABTOT. An agent can distinguish this from get_about and the list_* siblings 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 explicit when-to-use triggers: who the customer contracts with, who takes payment, whether the trip is financially protected, or about ATOL. It does not name an alternative tool or state exclusions, so it stops short of a 5, but the usage context is unusually clear.

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