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

Annotations already establish readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds genuinely non-obvious behavior beyond that: the return value is procedural guidance (screens, buttons, fields) and the tool performs no side effects on the account. It leaves out whether the guidance is account-specific or static, and what the response looks like structurally.

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 operational sentences are front-loaded and earn their place, but the third sentence about Eventbrite's public REST API, discounts and reports is background trivia that does not change how an agent invokes this tool. Sentences are also long and clause-heavy, mixing the tool's behavior with ecosystem commentary.

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 output schema, the description must carry the return-value burden, and it does: it tells the agent to expect a step-by-step procedural answer rather than attendee records. Combined with the explicit pointer to the cotlet_browser_* tools for execution, an agent has enough to call this correctly. Only the exact shape of the returned steps remains unspecified.

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 with additionalProperties false, so there is no parameter semantics to explain and the baseline of 4 applies. The description appropriately spends no words on arguments and instead explains the calling pattern.

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 names a specific verb and resource ("List attendees in the user's own Eventbrite account") and then explicitly clarifies the actual mechanic: it returns step-by-step instructions rather than data. That clarification is essential because the name alone would mislead an agent into expecting a data return. It stops short of distinguishing itself from nearby siblings like eventbrite_list_orders or eventbrite_email_attendees, which all deal with the same attendee/order domain.

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 gives a clear usage path: call this first to get the click-by-click procedure, then execute it with the cotlet_browser_* tools in the user's Eventbrite Cloud Browser. The phrase "opens nothing by itself" correctly signals this is not the execution step. It does not state when to prefer a sibling such as eventbrite_list_orders or eventbrite_email_attendees instead.

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