set_contact_regional_setting

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

No annotations provided. The description implies a write operation but does not disclose permissions, reversibility, error handling, or what happens if region-specific parameters are invalid.

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 efficient sentences, no wasted words, and front-loaded with purpose and usage direction.

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?

No output schema; the description fails to mention return values, error handling, or prerequisites (e.g., contact must exist). Incomplete for a tool with three required parameters and a nested object.

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 100%, so the description adds little beyond the schema. It reinforces that params are region-specific but provides no additional semantic meaning for the parameters.

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 clearly states the verb 'set' and the resource 'region-specific contact settings', listing the specific regions (EU, Latvia, Lithuania) and distinguishing it from sibling tools like set_privacy or set_whois_contacts.

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 description says to 'pass the appropriate parameters for the region', providing some guidance but without explicitly stating when not to use this tool or contrasting with related tools like set_whois_contacts.

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