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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered. The description adds genuinely new behavioral context that the annotations cannot convey: the call performs no action and opens nothing, and its return value is procedural guidance rather than data. It does not describe length, formatting or failure modes of the returned instructions, which keeps it below a 5.

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 clarification is front-loaded and useful, but the API sentence is padded ('Weezevent's official API: Weezevent has a REST API...') and the '(checked 31 Oct 2026)' provenance note adds little for an invoking agent. The 'from ChatGPT, Claude or any AI agent' clause is filler in a definition the agent already reads.

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 zero parameters, no output schema and rich annotations, the description carries the right amount of information: what it returns, that it acts on nothing, and which tools perform the actual work. Nothing critical is missing for correct invocation, though a hint about how the returned steps should be sequenced would make it fully self-contained.

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, which is the baseline-4 case per the rubric. The description correctly implies a parameterless call by describing it as guidance for the user's own account, with no inputs to document.

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 (get the participation report in the user's own Weezevent account) and explicitly discloses the output form: step-by-step screens, buttons and fields rather than the report data itself. It also distinguishes itself from the API-oriented siblings by noting the official API only reads tickets and attendees. Minor deduction because the tool name says 'get report' while the tool actually returns instructions for obtaining it, requiring the description to correct the name.

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 clearly directs the agent how to proceed: this tool returns instructions and opens nothing, then the actual work is done with the cotlet_browser_* tools in the user's Weezevent Cloud Browser. The API note implicitly explains why this guide tool exists instead of a data-fetching sibling. It stops short of naming a specific alternative sibling (e.g., weezevent_list_attendees) or stating when NOT to use it.

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