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

The annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, and the description reinforces rather than contradicts them by stating it 'opens nothing by itself' and only returns procedural guidance. It also names the follow-up tool family and the environment (the user's Cloud Browser) needed to actually perform the action, which is context the annotations do not carry.

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?

The functional behavior and the handoff to the browser tools are front-loaded in the first two sentences. The trailing 'Bizneo's official API ... checked 22 Oct 2026' sentence is somewhat tangential to invoking this tool, though it does add a small amount of relevant platform context.

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?

For a zero-parameter, non-mutating helper with no output schema, the description covers everything an agent needs: what it returns (steps, screens, buttons, fields), that it has no side effects, and which tool family to use next. Nothing required to call it correctly is absent.

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 and there is no parameter semantics to clarify. The description correctly implies the call needs no input and returns guidance text.

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?

The description states a specific verb and resource: it returns step-by-step instructions for requesting an absence in the user's OWN Bizneo account. The scope word 'own' implicitly separates it from siblings like bizneo_approve_absence_request and bizneo_reject_absence_request, which act on other people's requests, though no sibling is named explicitly.

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?

It gives a clear usage path: call this first to get the procedure, then execute it with the cotlet_browser_* tools in the user's Bizneo Cloud Browser. What is missing is an explicit exclusion, e.g. when to prefer bizneo_list_absence_requests or bizneo_get_absence_balance instead.

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