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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds genuinely useful behavior: it returns preassembled published facts, photos, routes and enquiry links with no model round trip, and explicitly states there is no live booking or payment. That 'no round trip / no booking' disclosure is the kind of context annotations cannot carry.

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?

Front-loaded with the core purpose before the examples and constraints. The three-scenario clause is dense and somewhat list-like, but each scenario earns its place by mapping to a valid intent value rather than padding.

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, the description carries the return-value burden and does so by enumerating the payload (facts, photos, routes, enquiry links). Both required parameters are accounted for and the closed-world/geography constraint is stated, though a note on what happens for unsupported country codes would close the last gap.

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 coverage is 50% and only country_code carries a schema description, but the description compensates by decoding the opaque intent enum values into plain-language scenarios (staff party with activity and food at Kordin; Halloween prison photos and BBQ; indoor laser tag and VR in St Julian's) and by reinforcing the Malta-only geography restriction on country_code.

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?

Names a specific verb (get) and resource (quick recommendations) and immediately grounds it in three concrete route scenarios that map to the intent enum values. The closing line about 'preassembled published facts' and the routing to a specialist consultant makes it clearly distinguishable from the consult_* and catalogue_* siblings.

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 ('fast first choice for a matching common need'), a hard boundary ('use only if the specific route fits the customer geography and constraints; never substitute another country or unwanted activity'), and a fallback ('for other needs or exclusions use a specialist consultant'). It stops short of naming which specific sibling tool to fall back to, leaving the agent to pick from consult_activities/consult_events/consult_venues.

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