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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and the description is consistent with that by stating it "opens nothing by itself." It adds useful context about what is returned (step-by-step screens, buttons, fields) and the execution path. However, it is silent on scope limits, what happens if the user lacks permissions, or why the API-availability note matters to the agent.

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 core workflow is front-loaded and efficient, but the closing fragment "Paired Plus's official API: The ProSolutions Paired host publishes API help, but no self-serve API key or onboarding guide was found" is a dangling note whose relevance to invoking this tool is unclear. It reads like leftover research rather than actionable guidance.

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 tool, the description covers the essential behavior (returns steps, executes nothing) and the follow-on tool to use. What remains missing is scope: which booking resources, and whether the returned steps differ by task, which an agent would need to know to route correctly among the many paired_plus_* siblings.

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 baseline of 4 applies; there are no argument semantics for the description to explain. The description correctly implies a parameterless discovery call by describing it as returning instructions rather than accepting 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?

The name and description say "manage booking resources," but "manage" is a generic verb and the description never specifies what a booking resource is (rooms, equipment, staff?) or which operations fall under management. It does clearly establish the tool's real function — returning step-by-step UI instructions rather than performing the action — which meaningfully separates it from execution-oriented siblings.

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?

The description gives an explicit two-step workflow: call this first to get screens/buttons/fields, then execute via the cotlet_browser_* tools in the Paired Plus Cloud Browser. It clearly signals this tool does not act on its own. It doesn't say when to pick this over siblings like paired_plus_manage_service or whether those siblings behave the same way, so no true alternative comparison.

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