add_country_region_settings

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

No annotations provided, so the description must carry the full burden. It only states that settings are added and raises a generic error if unsuccessful. It does not disclose whether adding overwrites existing settings, requires specific permissions, or what side effects occur. This is insufficient for a mutation operation.

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?

The description is short and front-loads the purpose, but the Args section duplicates the schema without adding useful detail. It does not violate conciseness but could be more efficient by integrating parameter descriptions into a single paragraph.

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?

Given the tool has 3 required parameters (including 'self' which is undocumented), a nested input object, and an output schema (not shown), the description is notably incomplete. It omits one parameter, provides no behavioral notes, and does not explain return values. For a tool of moderate complexity, this falls short.

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 description coverage is 0%, so the description should compensate. However, it only lists 'site_url' and 'settings' with one-line descriptions, omitting the required 'self' parameter entirely. It provides no guidance on the structure of 'settings' despite a complex schema (including CountryRegionSettings with multiple typed fields). The description adds minimal value over the raw 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?

The description clearly states the action 'Add country/region settings for a specific site,' which is a specific verb+resource combination. It distinguishes from sibling tools like 'get_country_region_settings' and 'remove_country_region_settings' by being additive, but does not elaborate on what 'settings' entails beyond the name.

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?

No explicit guidance on when to use this tool versus alternatives (e.g., 'get_country_region_settings' for retrieval or 'remove_country_region_settings' for deletion). The description only states the basic action without context or prerequisites, leaving the agent to infer usage.

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