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

Annotations already declare this a safe read (readOnlyHint=true, destructiveHint=false), so the bar is lower, and the description still adds real value: it discloses result ordering (newest first) and an auth prerequisite (a Cotlet API key with access to this app). Pagination behavior is not mentioned, which keeps it short of 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 leading sentence restates the title and is then repeated almost verbatim ('Lists tickets that fans passed to another fan, newest first, with the date and the orders involved'), so a sentence does not fully earn its place. Front-loading is good and the remaining sentences are tight.

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 two-parameter, filter-only read tool with no output schema, the description covers scope (all events vs one event), time filtering, ordering, and the auth requirement. Only the return shape/paging is left unaddressed, a minor gap given the annotations.

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?

Schema coverage is 100%, so both parameters are already documented in the schema; the description's statements about event_id and since largely restate the schema's defaults. It adds no format or syntax detail beyond what the schema provides, making the baseline 3 correct.

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?

States a specific verb and resource: lists tickets that were passed from one fan to another, sorted newest first, including date and related orders. That is clearly distinct in substance from siblings like dice_list_orders or dice_list_ticket_holders, though it never names an alternative to route between them.

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 explains the default scope ('Leave event_id out to cover all your events') and the narrowing effect of 'since', which is useful context, but there is no when-to-use versus another tool guidance and no exclusions or prerequisites for selecting this over the other list endpoints.

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