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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the description need not restate safety. It still adds real behavior an annotation cannot: it performs no action itself (“opens nothing by itself”), it returns step-by-step UI instructions, and it requires handoff to the browser tools. The API-plan note explains why browser automation is the path rather than an API call, which is meaningful operational context.

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 behavior and the handoff to cotlet_browser_* tools are front-loaded and clear. However, the opening clause largely restates the title, and the final sentence spends considerable length on Enterprise pricing and a checked-on date, which is rationale rather than decision-relevant content for invocation. The result is longer than the decision it supports.

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 zero parameters, no output schema and rich annotations already covering safety and idempotency, the description supplies the two remaining essentials: what is returned (step-by-step screens, buttons, fields) and what the agent must do next (browser tools). Only the absence of any precondition or sibling routing keeps it from full completeness.

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; there is nothing for the description to disambiguate. The empty schema with additionalProperties=false is self-explanatory and no parameter meaning is missing.

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 makes the real output explicit: it "Returns how to do it in AestheticsPro step by step (screens, buttons, fields) and opens nothing by itself," which corrects the misleading 'send' framing inherited from the name and title. What the tool actually produces is therefore unambiguous. It does not, however, distinguish itself from nearby configuration siblings such as aestheticspro_configure_appointment_confirmations or aestheticspro_set_appointment_reminder_timing.

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?

There is implied workflow guidance: fetch the steps here, then execute them with the cotlet_browser_* tools in the AestheticsPro Cloud Browser. That tells an agent the follow-on step, which is genuinely useful. But there is no statement of when to prefer this over sibling reminder/confirmation configuration tools, nor any exclusion or prerequisite (e.g. an active AestheticsPro subscription or browser session).

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