search_regions

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

No annotations are provided, so the description carries the full burden. The verb 'search' suggests a read-only operation, but the description does not explicitly state that it has no side effects, requires no auth, or is safe to call repeatedly. It is adequate but not fully explicit.

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 concise and to the point, with no extraneous words. It effectively conveys the core purpose and a key usage hint in a single sentence.

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?

While the description provides a usage hint, it omits essential parameter semantics. Without knowing what 'q' and 'country_only' do, an agent cannot reliably invoke the tool. Given no output schema, the description should at least cover input expectations, which it does not.

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 schema provides no descriptions for the parameters 'q' and 'country_only', and the description does not explain them either. With 0% schema description coverage, the description should compensate, but it fails to define what 'q' represents or how 'country_only' affects the search.

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 a specific verb ('search') and resource ('Agenzax's region taxonomy'), with a purpose of resolving a region_id. It does not explicitly differentiate from the sibling 'search_categories', but the resource is distinct enough.

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 explicit when-to-use guidance: 'call this before register_profile/search_directory to resolve a region_id.' This is actionable and helps the agent sequence tool calls, though it does not mention alternatives or edge cases.

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