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

The annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds a free-account query limitation, but it does not explain return shape details such as tie handling or whether counts are exact versus estimated.

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, front-loads the core purpose, and adds the access constraint without unnecessary wording.

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?

With four parameters, 0% schema description coverage, and no output schema, the description is too thin. It does not clarify the roles of visa, state, and occupation, nor does it explain the returned aggregate count beyond the initial sentence.

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. It clarifies 'score' and hints at occupation/pathway usage, but it does not explain the required 'visa' parameter or the optional 'state' parameter, leaving key inputs ambiguous.

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 specific verb and metric: return the aggregate number of submitted EOIs at or above a score. It scopes this to one pathway, but does not explicitly differentiate the tool from siblings such as get_score_distribution or compare_pathways.

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?

It provides access context by noting that free accounts can query any single occupation in the latest exact pathway. However, it gives no explicit guidance on when to use this tool versus get_score_distribution or other score-related siblings.

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