youtube_analytics_geography

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not describe what dimensions/metrics are returned, whether results are limited to specific time ranges, how max_results interacts with output, or any thresholds/limits. For a data-retrieval tool with zero annotation coverage, this is a significant gap.

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?

Four sentences, well organized with an Args section. No wasted words. Each sentence earns its place, and the parameter documentation is structured clearly.

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?

No output schema exists, and the description doesn't describe the return format (e.g., country codes vs names, whether it's a ranked list, what metrics besides views are included). For an analytics tool among 13 similar siblings, this under-specification makes it hard to distinguish and trust the tool.

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 compensate. The Args section documents all three parameters (start_date, end_date, max_results) with formats and defaults, which adds value beyond the bare schema. However, it doesn't clarify details like date format validation or how max_results bounds the country list.

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 'Get views by country' which is a clear verb+resource combination. It distinguishes reasonably from the many youtube_analytics_* siblings since it's specifically about geographic breakdown, though it doesn't explicitly differentiate itself from similar analytics tools.

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?

There is no guidance on when to use this tool vs alternatives like youtube_analytics_demographics, youtube_analytics_traffic_sources, or youtube_analytics_overview. No exclusion criteria or context about when geographic breakdown is appropriate.

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