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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true and openWorldHint=false, so the safety profile is covered. The description adds genuine context beyond that: it 'opens nothing by itself' and returns instructional content, which prevents an agent from assuming a side effect occurred. It does not state auth/prerequisite requirements or the shape of the returned steps, so it is not fully exhaustive.

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 first two clauses carry the operative information (what it does, what it returns, what to do next) and are front-loaded. The closing sentence about AestheticsPro's Enterprise-only Custom API is somewhat long but earns a place by explaining why browser automation is the path rather than an API call.

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, annotation-covered tool with no output schema, the description supplies the critical missing piece: that the return value is a step-by-step procedure and that a separate browser tool performs the action. Only minor gaps remain (no detail on how the steps are formatted or any prerequisite state in the account).

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 there is nothing for the description to disambiguate. Baseline 4 applies; the description correctly avoids inventing parameter details.

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 uses a specific verb+resource ('Enable Touchpoints in the user's own AestheticsPro account') and immediately clarifies the actual output: step-by-step screens/buttons/fields rather than a live change. An agent can distinguish this from write-oriented siblings like aestheticspro_configure_client_portal without opening the schema.

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 states the ordering explicitly: call this first to get the walkthrough, then 'do it with the cotlet_browser_* tools in the user's AestheticsPro Cloud Browser.' That routes the agent to the correct follow-up tool. It stops short of true exclusions (when not to use this versus a native-API path), which keeps it below a 5.

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