Itu Zones Source Info

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

With no annotations at all, the description carries the full burden. It conveys that this is a passive metadata/source description (no mutation implied) and even mentions terms and SHA-256 hashes, suggesting licensing and integrity context. However, it does not state the return shape, format, or that it requires no parameters—gaps for a zero-annotation 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?

A single dense sentence that front-loads ownership and edition before listing terms and file integrity data. Every clause adds distinct information with no 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?

An output schema exists, so the description need not enumerate return values; it instead summarizes the categories of information returned (owner, edition, terms, file URLs, hashes). For a zero-param metadata tool this is largely complete, though a sentence on freshness or how the edition is determined would strengthen it.

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?

There are zero parameters, so the baseline is 4. The schema is trivially complete, and the description correctly implies no inputs are needed.

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?

The description names the specific resource (the ITU zones list) and enumerates what information is served: ownership, edition, terms, file URLs, and SHA-256 hashes. That distinguishes it from lookup/search siblings, which query zone data rather than describe the dataset's provenance.

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?

There is no explicit when-to-use guidance and no mention of alternatives. The sibling names imply this is the provenance/metadata tool rather than a query tool, but the description itself offers no routing guidance and doesn't say when an agent should reach for this versus get_version_info.

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