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

No annotations are provided, so the description bears the full behavioral disclosure burden. It does not state whether the tool fetches live data, generates a static summary, requires authentication, has rate limits, or returns a structured or narrative output. Without that context an agent cannot anticipate side effects or response characteristics.

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 the phrase 'economy, regulation, and market' is informative, but the redundant 'Country Brief: Country brief' wastes space. It front-loads the topic but the low information density means it does not use its brevity effectively.

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 3-parameter tool with no output schema and no annotations, the description should explain what constitutes a country brief, what the parameters mean, and what the agent can do with the result. It explains none of these. The mention of economy/regulation/market gives some scope, but there is no clarification of output format, data source, or parameter roles.

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 coverage is reported as 100%, but the schema descriptions are tautological ('Country to process' etc.) and add no meaning. The description adds a country focus, but does not clarify whether 'name'/'input' are alternative ways to specify context or how they differ from 'country'. The agent is left guessing at the parameter roles.

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 identifies the domain (economy, regulation, and market) and format (brief), but there is no verb indicating what action the tool performs, no output definition, and the resource is merely restated as 'Country brief.' It lacks specificity to distinguish it from similar briefing tools like world-brief, eu-brief, defi-brief, or market-overview.

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 such as world-brief, eu-brief, or country-code. The name and 'Country brief' imply country-specific use, but nothing explicitly states when this tool should be selected or what information it is best suited for.

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