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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds the non-obvious trait that the tool is advisory only and performs no action ("opens nothing by itself"), which is exactly the kind of context annotations cannot express. It stops short of describing the shape of the returned steps.

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 middle sentence is dense but carries the essential workflow handoff. The final sentence about Bokadirekt's official API is cryptic and does not clearly earn its place, and the misleading first clause should have led with the advisory nature instead.

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 guidance tool, the essentials (what it returns, that it performs no action, and which tools to use next) are present. What is missing is disambiguation of the retrieval framing versus the actual instruction-returning behavior, and any sense of what the step output looks like, which leaves real ambiguity for an agent deciding whether to call it.

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 is trivially complete and the description has nothing to compensate for. Baseline 4 applies; no parameter meaning is needed or missing.

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 opening sentence says "List waitlist in the user's own Bokadirekt account," which reads as a data-retrieval operation, but the second sentence reveals the tool actually returns step-by-step UI instructions and "opens nothing by itself." The real behavior is disclosed, but the lead line points an agent at the wrong expectation, and nothing distinguishes this from siblings like bokadirekt_list_bookings.

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 explicitly routes the agent onward: "then do it with the cotlet_browser_* tools in the user's Bokadirekt Cloud Browser," which is a concrete alternative workflow. It does not state when not to call it, and the trailing "official API: Yes, but it only reads" is ambiguous about whether API-based listing is available.

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