pop_growth

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

With no annotations provided, the description carries full burden for behavioral disclosure. It only states the source of data (UN WPP) but does not disclose traits like data freshness, units of growth, or any potential limitations. The description is minimal and fails to inform the agent about side effects, rate limits, or operational 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 a single, front-loaded sentence with zero waste. Every word adds value: 'Population growth data for a country from UN World Population Prospects.' Perfectly concise.

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?

The tool is low-complexity (1 param), but there is no output schema. The description does not explain what the output contains (e.g., yearly growth, percentage, historical range). Without the output schema, the description should compensate by describing the return format or structure, which it does not. Incomplete for an agent relying on the description alone.

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 100%, so the baseline is 3. The description adds no extra meaning beyond what the input schema already provides for the 'country' parameter (country name or 3-letter ISO code). No additional semantics or usage notes are given.

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 it provides 'Population growth data for a country' from a specific source (UN World Population Prospects). The verb 'data' and resource 'country' are clear, but it does not explicitly differentiate from sibling tools like pop_age_structure or pop_density, though the 'growth' qualifier implies distinction.

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. There are no when-to-use/when-not-to-use instructions, nor any mention of context or prerequisites. The description assumes the user knows when to request population growth data.

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