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

readOnlyHint=true already covers the safety profile, so the description's remaining obligation is light. It does add the raw endpoint (GET /public-api/v1/terminations/) and pagination behavior, but says nothing about sort order, record volume, or whether all terminations or only current-period ones are returned.

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, front-loaded with the purpose before the pagination note. The trailing bare endpoint is marginally useful for error diagnosis but is the weakest part of an otherwise lean definition.

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?

There is no output schema, so the description is the only place an agent could learn what a termination record contains (employee reference, effective date, type, reason). It never says, leaving the return shape unknown for a list tool whose whole job is returning records.

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 coverage is 100% and the single optional parameter is already documented as 'Page number, 1-based (default 1). Use next_page from the previous reply.' The description's 'Paged: pass next_page as page' largely restates the schema, so the baseline of 3 is appropriate.

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 employee terminations') and disambiguates the domain with the parenthetical '(resignations and dismissals recorded in Jet HR)', which matters because the sibling set also contains jethr_list_hirings. It never names an alternative sibling explicitly, but the concept is unambiguous.

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: an agent can infer this is the enumeration endpoint for terminations, and there are no exclusions or alternatives offered (e.g. when to use list_employees vs this tool to find leavers). The only procedural guidance is pagination mechanics, not when-to-use.

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