search_countries

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

Annotations are minimal (readOnlyHint=false, destructiveHint=false) and the description adds no behavioral context. It does not mention pagination, filtering semantics, request body expectations, or any side effects, leaving the agent without critical operational insight.

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 brief but under-specified. It lacks any explanatory structure or details, so while it is concise in word count, it sacrifices all informative content and fails its purpose.

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?

With four parameters, no output schema, and sparse annotations, the description must provide substantial guidance. Instead it is entirely inadequate, offering no information about the request body, search semantics, or how to use the pagination parameters, making the tool effectively unusable without external documentation.

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 covers all four parameters (body, limit, offset, order_by) with descriptions, so the baseline is 3. The tool description adds no additional meaning to the parameters, and the body description is vague ('as defined by the bexio API'), but the schema itself provides reasonable context.

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 'Search countries' is nearly a tautology of the tool name, providing no specific verb, resource details, or scope. It does not distinguish from siblings like 'list_countries' or 'get_country', leaving the agent uncertain about what 'search' uniquely offers.

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 guidance is given on when to use this tool versus alternatives. Sibling tools such as 'list_countries' and 'search_countries' overlap, but the description lacks any comparison, exclusions, or context to help the agent choose correctly.

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