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

Annotations already declare readOnlyHint=true, destructiveHint=false and idempotentHint=true; the description reinforces and explains that by stating it "opens nothing by itself" and only returns screens, buttons and fields. It also discloses the constraint that execution must go through the browser tools because AestheticsPro has no public API. It adds real behavioral context beyond the annotations, though the exact shape of the returned instructions is only loosely described.

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 workflow is front-loaded and clear, but the closing sentence about AestheticsPro's $350/month Enterprise plan, custom API work and the "checked 11 Nov 2026" date is verbose justification that could be compressed to a short clause. The parenthetical list of screens, buttons and fields is useful but the pricing detail does not earn its space in a tool description.

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 parameters and no output schema, the description carries the burden of explaining what comes back, and it does so at a high level (step-by-step instructions covering screens, buttons and fields). It also explains the required follow-up tooling. A brief note on how large or structured that guidance is would make it complete.

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, which is the baseline-4 case. The description is consistent with that, describing an argument-free guidance lookup rather than implying any inputs.

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 ("Create staff calendar in the user's own AestheticsPro account") and immediately clarifies that the tool does not actually create anything but returns step-by-step instructions. That resolves the mismatch between the name and the behavior. It does not distinguish itself from plausible siblings such as aestheticspro_create_room_calendar or aestheticspro_set_staff_schedule, so it falls 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?

It gives a clear usage path: call this to get the steps, then execute them with the cotlet_browser_* tools in the user's AestheticsPro Cloud Browser. It also implicitly says this is for the user's own account. It offers no explicit when-not guidance or comparison to the other calendar-creation siblings, 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.
