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

Annotations declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, and the description reinforces this with 'opens nothing by itself', so there is no contradiction. It adds useful context beyond the annotations by explaining the intended two-phase workflow (guide first, browser automation second) and why the official API is not an option (Enterprise-only).

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, which is good, but the opening clause 'from ChatGPT, Claude or any AI agent' is filler that does not help tool selection. The trailing API note is somewhat useful justification for the browser path, yet it is wordy and reads like an aside.

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, no output schema and a safe read-only profile already covered by annotations, the description supplies what is missing: the shape of the return value (step-by-step screens, buttons, fields) and the follow-up mechanism. An agent has enough to call it correctly and know what to expect back.

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 is 4 and there is nothing the description could add on this dimension. Schema coverage is 100% and the empty object schema is unambiguous.

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 description states a specific verb and resource ('Book from waitlist in the user's own Boulevard account') and clarifies the tool's actual output: step-by-step screens, buttons and fields rather than a booking action. It does not explicitly differentiate itself from the sibling boulevard_book_appointment, so an agent must infer that this one returns instructions while that one presumably acts.

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?

Clear usage context is given: call this to obtain a step-by-step walkthrough, then execute it via the cotlet_browser_* tools in the Boulevard Cloud Browser, since 'opens nothing by itself'. No explicit when-not-to-use or comparison against boulevard_book_appointment is provided.

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