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

readOnlyHint=true already declares the safety profile, so the description's added value is in disclosing the result shape (title, status, location, department, publish date, hiring steps) and that closed positions are included by default. That is meaningful behavioral context absent from annotations, though pagination and ordering are unstated.

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?

Two short sentences with no filler; scope and returned fields come first, and the follow-on hint is placed last where it belongs. Every clause carries information.

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 no output schema and no parameters, the description must carry the return-value burden, and it does by naming the fields returned and the open/closed scope. Gaps remain around pagination, result volume, and whether any filtering exists, which matter for a list tool on a potentially large dataset.

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 tool takes zero parameters, so the baseline is 4. The description correctly signals there is nothing to supply and instead redirects the 'id' mention to the applicant-listing tool, avoiding confusion about a nonexistent input.

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?

States a specific verb and resource ('List the company's job positions') plus scope ('open and closed') and enumerates the returned fields, so an agent knows exactly what it gets. It also points at the follow-on tool (list a position's applicants via the id), which partially separates it from talenthr_list_job_position_applicants, though it never names that sibling outright.

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?

Usage is only implied: the tool lists all positions, and the trailing sentence about using the id to list applicants hints at the workflow. There is no explicit when-to-use, when-not, or named alternative such as talenthr_list_job_titles or talenthr_list_job_position_applicants.

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