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 safety profile is covered; the description consistently reinforces this with 'opens nothing by itself'. It adds genuinely useful context about the return content (screens, buttons, fields) and why the browser path is needed (partner-only REST API). It stops short of describing the shape/length of the returned guide or any failure modes, so a 3 is appropriate given annotations carry the safety burden.

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 purpose is front-loaded and the workflow handoff follows logically. However, 'from ChatGPT, Claude or any AI agent' is marketing filler, and the closing API paragraph with the '(checked 31 Oct 2026)' date is tangential to selecting or invoking the tool. Trimming these would sharpen an otherwise reasonable length.

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 must explain what comes back and what the agent does next — and it does both (step-by-step screens/buttons/fields, then act via cotlet_browser_*). Given the tool's simplicity, the agent has enough to invoke it and use the result correctly; only the format/length of the returned guide is left implicit.

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 absence of a parameter is consistent with 'returns how to do it', confirming the agent passes no arguments.

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?

States a specific verb and resource (list attendees in Weezevent) and clarifies the non-obvious twist that it returns step-by-step instructions rather than the data itself. The name alone would mislead an agent into expecting a data fetch, so the description is what corrects it. It does not explicitly differentiate from siblings like weezevent_list_events or weezevent_list_orders, but the resource distinction is self-evident.

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?

Gives a clear handoff: use this to get the procedure, then execute it with the cotlet_browser_* tools in the Cloud Browser. This tells the agent both when to use this tool and what to do immediately after. It lacks an explicit 'do not use when' clause or comparison against the other weezevent_* tools, which keeps it from a 5.

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