get_drought_status

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

With no annotations, the description discloses return values (drought phase scale, rainfall deficit, population affected). It does not mention authorization or side effects, but for a read-only get operation, this is adequate.

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 plus a parameter line, front-loading purpose and return format. Every sentence adds value with zero waste.

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 no output schema, the description explicitly lists return fields (phase, deficit, population). It also distinguishes from siblings. Missing details like error handling or rate limits, but these are not critical for this simple 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?

The schema has 0% coverage (no description for 'county'). The description adds meaningful context: 'county: Kenya county name e.g. Turkana, Marsabit, Garissa', clarifying the parameter's domain and providing examples.

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 gets current NDMA drought phase classification for a Kenya county, specifying the resource and scope. It distinguishes from siblings 'get_drought_alerts' and 'sms_drought_alert' by focusing on status vs alerts.

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 implies use for current status queries, and examples of counties guide parameter input. While it doesn't explicitly state when not to use or mention alternatives, the purpose is clear enough for an agent to select appropriately.

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