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

The annotations already signal safety (readOnlyHint=true, idempotentHint=true, destructiveHint=false), so the description is not required to re-assert those. It adds mild context about the data being geopolitical and time-bounded, but it does not explain what the tool returns or how the look-back window behaves beyond the parameter name.

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 compact sentence with no filler and places the main concept first. It is concise, though the brevity comes at the cost of parameter guidance.

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 five optional parameters and no schema descriptions, the definition does not explain how to construct a useful request or how layers/region/severity interact. The output schema removes the need to describe return values, but the lack of usage context and parameter semantics leaves the agent undersupported.

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 description coverage is 0%, so the description must carry parameter meaning, but it only echoes 'layers' and 'look-back window' (days_back). Region, country, and severity are left completely unexplained, and there are no enums or format hints to compensate.

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 states a resource ('global geopolitical intelligence layers') and a temporal scope ('look-back window'), but it is a noun phrase with no explicit verb such as 'retrieves' or 'returns.' It does not distinguish get_geo_map from nearby siblings like get_country_brief or list_layers, so the purpose is recognizable but not precise.

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 provided about when to choose this tool over alternatives, and no exclusions or sibling references appear. The description only characterizes the data domain, leaving the agent to infer selection criteria from the name.

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