list_free_zones

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds modest context: 'every' signals an unpaginated complete enumeration, and 'curated dataset' hints at a bounded, possibly non-exhaustive source. It stops short of stating data recency or whether the list is authoritative.

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 short sentences, purpose first, return shape second — well front-loaded with no filler. The return-field sentence overlaps the output schema, costing a little redundancy.

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 and zero parameters, the description needn't explain return values or arguments, and it doesn't. The only meaningful gap is not positioning this list relative to the detail/compare tools in the same family.

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?

Zero parameters, which is the baseline-4 case; there is nothing to disambiguate. The description correctly adds no filtering or paging claims that would contradict the empty schema.

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 ('List') and resource ('every Dubai free zone') with a clear scope limit ('in the curated dataset'). It is distinguishable from free_zone_details and compare_free_zones by implication of a full enumeration, though it never names those siblings explicitly.

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 word 'every' implies this is the entry point for enumerating the catalog before drilling into details, but no explicit when-to-use or when-not guidance is given. Alternatives such as free_zone_details, compare_free_zones, and list_offshore sit right next to it and are left unaddressed.

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