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

Goes well beyond readOnlyHint=true by disclosing the auth scope required, the bounded single-page behavior with no auto-crawl, and an operational allowlist that excludes payroll, national IDs, private contact/health data and free-text comments. That last point materially tells an agent what data will and will not come back, which the annotations cannot convey.

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 short sentences, front-loaded with what the tool does and the auth requirement, then pagination, then data-scope caveats. No filler or restatement of the title.

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?

The return shape is sketched ('data plus opaque pagination tokens') and data exclusions are covered, which is good for a tool with no output schema. However, with 10 optional filter parameters at 20% schema coverage, an agent still cannot tell how to construct a meaningful query, leaving a real gap for a list tool.

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 description coverage is only 20% across 10 parameters, so the description must compensate, but it only explains pageToken iteration. The filter parameters (idIn, employeeIdIn, roleIdIn, groupIdIn, startDateGte/Lte, endDateGte/Lte) and pageSize get no explanation of semantics, including the overlap between idIn and employeeIdIn or what the date ranges filter on.

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 employee role assignments'), which is distinguishable from siblings like quinyx_list_roles and quinyx_list_employees. It never explicitly routes the agent away from those siblings, 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?

Gives concrete operational context: the required scope hr:role-assignments:read and the instruction to pass pageToken for further pages with 'no automatic crawl'. No when-not-use case or named alternative among the sibling list tools is provided, so it is clear context rather than full routing guidance.

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