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

Annotations already mark the tool as read-only and non-destructive. The description adds behavioral context: it automatically selects appropriate indicators based on focus and generates a structured report. This goes beyond annotations but does not detail other potential side effects.

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 concise and well-structured, using bullet points for focus options. It front-loads the core purpose and then details parameters and output efficiently. Every sentence adds value.

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 the presence of an output schema and annotations, the description covers purpose, parameters, and output format. It lacks discussion of error handling or prerequisites but is adequate for a non-destructive benchmarking 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?

Despite schema description coverage reported as 0%, the description compensates by explaining the focus parameter with detailed options and linking to the required country_codes parameter. It adds meaning beyond the raw schema by providing context for each focus area.

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 benchmarks multiple countries on a specific education topic using UNESCO UIS. It lists five distinct focus areas and contrasts with siblings by emphasizing automated indicator selection for structured comparison.

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 usage for benchmarking on specific topics but does not explicitly state when to use this tool versus alternatives like uis_compare_countries. No 'when-not-to-use' guidance or references to sibling tools are provided.

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