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

Beyond the readOnly/idempotent/non-destructive annotations, the description discloses two non-obvious behaviors: the return value is an instructional guide (screens, buttons, fields) and the tool performs no navigation on its own, requiring a separate Cloud Browser session. That resolves the otherwise confusing mismatch between the 'request' name and a read-only safety profile.

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 core is front-loaded well in the opening clause and the 'opens nothing by itself' caveat. The trailing sentence about Bizneo's official REST API and its 'checked 22 Oct 2026' date does not help an agent decide whether or how to call this guide-returning tool and reads as filler.

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 carries the return-value burden and does so adequately by stating the guide's granularity and that nothing is executed. It stops short of describing format (text vs structured), authentication, or error behavior when the user lacks Bizneo access, but the essentials for correct invocation are present.

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, and the schema is empty, so there is nothing to disambiguate; the description correctly spends no words on inputs. Baseline for a parameterless tool applies.

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 names a specific verb and resource ('Request remote work in the user's own Bizneo account') and immediately clarifies the actual output: a step-by-step how-to rather than a performed action. It does not explicitly contrast itself with the approve/reject siblings, but the request-vs-approve distinction is legible from the text.

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 follow-on workflow ('then do it with the cotlet_browser_* tools in the user's Bizneo Cloud Browser') and rules out side effects ('opens nothing by itself'), which is genuine usage context. However, no alternative is named for the case where the agent wants to approve or reject an existing request, and no prerequisites (login state, permissions) are stated.

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