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

Adds meaningful context beyond the annotations: it discloses that the return value is a step-by-step walkthrough (screens, buttons, fields) and that the call itself performs no action despite the imperative 'collect' name, which is consistent with readOnlyHint=true and destructiveHint=false. It also notes the absence of a self-serve API key path, explaining why browser automation is required.

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?

Front-loads the key fact (what it does and that it does not act) in the first sentence and covers execution and API context afterward. The final sentence about the ProSolutions Paired host is slightly awkwardly worded but earns its place by explaining the lack of an API route.

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, no-output-schema guidance tool, the description covers purpose, return shape ('screens, buttons, fields'), the no-side-effect guarantee, and the required follow-up tooling, leaving nothing an agent needs to call it correctly.

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; the empty schema is self-evident. Baseline of 4 applies.

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?

Names a specific verb and resource ('collect booking deposit' in 'Paired Plus'), and immediately clarifies the actual behavior: it returns step-by-step instructions rather than performing the action. It is distinguishable from action-performing siblings, though no sibling is named explicitly.

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 next step ('then do it with the cotlet_browser_* tools in the user's Paired Plus Cloud Browser') and states the tool opens nothing by itself, which implies when to use it. However, it names no sibling alternative and gives no when-not conditions, so a large catalog of Paired Plus booking/payment tools remains unrouted.

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