get_country_brief

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

No annotations are provided, so the description must fully disclose behavioral traits. However, it only lists the brief's contents (communication style, what works/kills deals, etc.) without mentioning if the operation is read-only, requires authentication, has rate limits, or what the return format is. For a tool with zero annotation coverage, this is insufficient.

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 two sentences, front-loaded with the purpose and a list of included items, followed by a usage recommendation. Every sentence contributes value without redundancy or verbosity.

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 low complexity (one required parameter, no nested objects, no output schema), the description covers the tool's purpose and contents well. It explains what the brief includes, which compensates for the lack of output schema. Minor omission: could mention return type or format, but overall complete.

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 100% description coverage for the single parameter (country), and the description merely echoes 'EMEA market' without adding new meaning. Per guidelines, baseline is 3 when schema_coverage is high, and the description adds no extra value beyond the 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 tool retrieves a 'complete country-specific buyer psychology brief' with explicit list of contents (communication style, deal dynamics, etc.). The verb 'Get' is specific, and the resource is well-defined, distinguishing it from sibling tools like get_compliance_check or get_followup_cadence which target narrower aspects.

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 clear usage context: 'Use this before any outreach to a specific EMEA market.' It implies this is an initial step, but does not explicitly exclude scenarios or mention when to use sibling tools instead. The guidance is present but lacks comparative alternatives.

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