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

Beyond the read-only and non-destructive annotations, it discloses the instructional return value, states that it opens nothing itself, and delegates execution to separate browser tools. It could more explicitly state that this call never changes member labels and that the follow-up browser actions can mutate the account and may require an authenticated session.

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 workflow sentence is dense and useful, but the crucial guide-only behavior appears only after an action-oriented opening. The phrase "from ChatGPT, Claude or any AI agent" and the dated official-MCP-server survey add little invocation value, making the description longer than necessary.

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 tool without an output schema, it adequately describes the returned guidance, the absence of automatic browser opening, and the execution handoff. It remains less complete about browser-session or authentication prerequisites and could warn more explicitly that only the subsequent browser steps apply the labels.

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 has zero parameters, so there is no input syntax or option behavior requiring explanation; the zero-parameter baseline applies. References to the user's own Ghost account and Ghost Cloud Browser add useful environmental context without implying nonexistent 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?

It names the Ghost member-labeling task and clarifies that the tool returns step-by-step UI instructions rather than completing the labeling itself. However, the opening phrase "Label members" initially sounds like a direct mutation, and the description does not distinguish this app-specific guide from the more general cotlet_app_guide sibling.

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 provides a concrete workflow: obtain screens, buttons, and fields here, then use the cotlet_browser_* tools in the user's Ghost Cloud Browser to perform the steps. It does not provide explicit when-not-to-use guidance, prerequisites, or a condition for choosing this over cotlet_app_guide.

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