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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true and openWorldHint=false, so the safety profile is covered. Beyond that, the description adds a genuinely important trait the annotations cannot express: the tool performs no action itself and returns procedural steps, requiring a separate browser tool to actually complete the task. That is real value-add, though it doesn't say how the steps are shaped or whether state is read from the live account.

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 content is in the first two sentences and is reasonably front-loaded, but the third sentence about Eventbrite's public REST API v3 and the absence of an official MCP server does not help an agent decide or invoke this tool, and the parenthetical '(checked 5 Nov 2026)' is pure noise. Roughly a third of the text does not earn its place.

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 parameterless guidance tool with no output schema, the essentials are present: what it returns (step-by-step screens/buttons/fields), that it is side-effect free, and which tools to use next to finish the job. Missing is any sense of how the output is structured or whether it reads the current account state, and the API trivia paragraph detracts rather than completes the picture.

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 schema takes zero parameters with additionalProperties=false, so there is nothing for the description to disambiguate. The baseline for a 0-param tool is 4, and nothing here misrepresents the input contract.

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 first sentence says it will 'List orders in the user's own Eventbrite account', which reads like a data-returning list operation, but the second sentence reverses that by saying it 'Returns how to do it in Eventbrite step by step' and 'opens nothing by itself'. The real behavior (a guide/instruction generator, not a lister) is stated, but only after a misleading opener, so an agent must read past the first clause to understand what it actually gets back.

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 does give a concrete handoff: after getting the steps, perform the action with 'cotlet_browser_* tools in the user's Eventbrite Cloud Browser', which is genuine when/how guidance. However, it never distinguishes itself from the other Eventbrite listing siblings (eventbrite_list_events, eventbrite_list_attendees), and the closing claim that Eventbrite has 'no public event search' sits awkwardly against the existing eventbrite_search_public_events sibling, leaving the routing ambiguous.

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