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

With no annotations, the description carries the behavioral disclosure burden. It does mention that results are paginated and lists the job fields returned, which is useful. However, it does not disclose whether filters combine with AND/OR, default sorting, or any access requirements. Some transparency is present but more context could be given.

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 sentence that directly conveys purpose and the key return characteristic (paginated listings). It is concise and front-loaded, with no wasted words.

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 17 parameters, no annotations, and no output schema, the description is somewhat brief. It covers the core search functionality and return fields, but does not mention the extensive filtering options (location, salary, experience, etc.) or pagination controls. The schema covers these details, so the description is minimally complete but could provide a better overview.

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 input schema has 100% description coverage for all 17 parameters, so the description does not need to repeat parameter details. It adds no additional meaning beyond the schema, but the baseline is 3 when schema coverage is high.

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 action ('Search for jobs') and the resource ('NextJobz job portal'), and mentions the return format (paginated job listings with specific fields). No sibling tools exist, so differentiation is not required.

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 clearly implies when to use the tool (whenever a user needs to search for jobs on NextJobz). No alternatives or exclusions are stated, but the lack of sibling tools reduces the need for explicit when-not guidance.

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