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

'Opens nothing by itself' reinforces the readOnlyHint annotation rather than contradicting it, and the description discloses what is returned (screens, buttons, fields) — genuinely useful context beyond the annotations. The official-API pricing aside is relevant background but is not about this tool's own behavior, so it doesn't quite reach a 5.

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 sentences are front-loaded and efficient, stating the action, the return content, and the follow-up tool. The third sentence about the official API's variable pricing and a quoted date is tangential to invoking this tool and dilutes the focus.

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, no output schema, and read-only annotations, the description covers what the agent needs: what the tool returns, that it performs no action, and which tools actually execute the change. It leaves minor gaps — e.g., how to specify which service to create or clone — but those are small for a zero-input guidance tool.

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 schema imposes no burden and the baseline is 4. The description adds nothing about inputs because there are none to explain; intent must be expressed in natural language, which is not addressed.

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 combination (create, clone, configure services) and then immediately clarifies the actual behavior: it 'Returns how to do it in Exercise.com step by step (screens, buttons, fields) and opens nothing by itself.' That correction is essential because the name implies a write action. It doesn't explicitly distinguish itself from service/package siblings like exercise_com_review_changes_made_to_services_and_packages, which keeps it from 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 perform them with the cotlet_browser_* tools in the Cloud Browser. That is an explicit next-step alternative. It does not say when to choose this over the package- or change-review siblings, so it falls short of full when/when-not guidance.

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