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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states what the tool does but doesn't describe any behavioral traits: no information about permissions needed, rate limits, pagination, error conditions, or what format the data returns (e.g., list, JSON structure). For a read operation with zero annotation coverage, this is a significant gap.

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 a single, clear sentence with no wasted words. It's appropriately sized for a simple lookup tool and front-loads the core functionality immediately.

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?

For a tool with no annotations, no output schema, and 0% schema description coverage, the description is incomplete. It doesn't explain what the return data looks like (structure, fields), doesn't mention error handling or edge cases, and provides minimal parameter guidance. Given the complexity of geographic data and many similar sibling tools, more context is needed for effective use.

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?

The input schema has 1 parameter with 0% description coverage, so the schema provides no semantic information. The description mentions 'within a specific region' which implies the parameter is a region identifier, but doesn't specify what 'regionCode' represents (e.g., numeric code, abbreviation, name), valid formats, or examples. It adds minimal value beyond the parameter name itself.

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 'Get' and the resource 'all cities and municipalities within a specific region', making the purpose explicit. It distinguishes from some siblings like 'get_cities' (which lacks region specificity) or 'get_region' (which returns region data, not cities/municipalities), but doesn't explicitly differentiate from close siblings like 'get_region_cities' or 'get_region_municipalities'.

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 provides no guidance on when to use this tool versus alternatives. With many sibling tools that fetch similar geographic data (e.g., 'get_region_cities', 'get_region_municipalities', 'get_cities', 'get_municipalities'), there's no indication of when this combined cities/municipalities tool is preferred over separate tools or other region-based queries.

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