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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds real behavior beyond that: a default filter that silently hides inactive employees, and permission-gated expansion of the response with salary, IBAN and accounting fields flagged as sensitive HR data — an important disclosure an agent would otherwise miss.

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?

Three sentences, front-loaded with the action and the default scope, then the payload, then the filter families and the permission caveat, ending with the endpoint. The field enumeration is long but justified because there is no output schema to document the return shape.

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 ten optional parameters, no output schema and permission-dependent fields, the description covers exactly the gaps an agent would hit: default status scoping, which date dimensions can be filtered, what comes back, and that extra sensitive fields appear only under specific API-key permissions. Pagination is fully handled by the schema.

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% so the baseline is 3, but the description adds meaning the schema does not: that filtering defaults to active employees and that the library of date parameters is grouped into creation, joining, termination and deletion ranges. It does not add syntax or interaction rules (e.g., whether ranges combine with AND, or page/rpp interplay), so it sits just above baseline.

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?

A specific verb (list) plus resource (organization's employees) with an explicitly enumerated return payload (code, names, job title, department, business unit, employment type, line manager, joining date, status). The default scope (active only) is stated up front, which cleanly separates it from the singular jisr_get_employee and from the financial-info sibling.

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 gives clear conditions for filtering: 'active by default', plus date-range filtering on creation, joining, termination and deletion. It also implicitly routes financial-field consumers by noting the permission dependency, but it never explicitly names jisr_get_employee or jisr_get_employee_financial_info as the alternative for single-record or finance-only lookups.

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