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

Annotations only declare readOnlyHint=true, so the description carries real weight and delivers: the required hr:employees:read scope, the fact that pagination is manual via opaque tokens, and an explicit allowlist that excludes payroll, national IDs, private contact/health data and free-text comments. Missing only rate-limit or ordering guarantees to reach a 5.

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 tight sentences, front-loaded with what the tool does, then auth, then pagination, then data boundaries. No filler and nothing redundant with the annotations.

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, the description correctly steps in to describe the return shape (data plus opaque pagination tokens). Scope and data-exclusion boundaries are covered; the only gap is the unexplained idIn filter, which an agent would need to use the tool's main filtering capability.

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 67% and the description only reinforces pageToken behavior, which the schema already documents as an opaque nextPageToken. The idIn array — a digit-string ID filter capped at 50 items — receives no explanation in either the schema or the description, leaving its filtering semantics 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?

States a specific verb and resource — 'Read one bounded page of scheduling employee details' — which is clearly distinguishable from single-record siblings like quinyx_get_employee and from quinyx_list_shifts. It does not explicitly name a sibling, so it stops short of a 5.

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?

Implies usage via the pagination guidance ('pass pageToken for another page, no automatic crawl') and the required scope, but never states when to choose this over quinyx_get_employee for a single record or how idIn filtering should drive selection. Usage is inferable rather than explicit.

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