stubhub_trending_events

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

With no annotations provided, the description carries the behavioral disclosure burden. It discloses that the feed is paginated and global, lists the returned fields (name, date, venue, canonical URL), and usefully notes that a zero count with an empty events list is a valid no-results response. It stops short of full transparency by not mentioning default page size, auth requirements, or rate limits.

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 description is well structured: purpose first, then scope, sibling distinction, and no-results behavior. It is slightly repetitive with 'currently-trending individual events' appearing twice, and the first two sentences could be merged, but every sentence contributes useful information.

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 simple list tool with two optional parameters and no output schema, the description is largely complete. It covers return fields, filtering, pagination, the no-results edge case, and the sibling distinction. Missing details like default page size or pagination limits are minor and do not prevent correct selection and invocation.

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 description coverage is 100%, so the baseline is 3; both parameters already have meaningful descriptions in the schema. The description adds only that the feed is paginated and the category filter is optional/one vertical, which mostly restates schema semantics. It does not add enum value meanings or default page behavior.

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 opens with a specific verb and resource: it lists StubHub's currently-trending individual events. It further clarifies the scope as a paginated global feed with optional vertical filtering, and it explicitly distinguishes itself from stubhub-trending. An agent can clearly tell what this tool does and how it differs from the closest sibling.

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?

The description explicitly contrasts this tool with stubhub-trending, which rotates featured performers/teams rather than individual events, giving the agent a clear when-not and alternative. It also states the optional category vertical filter, so the intended calling context is clear. This is sufficient routing guidance for the key alternative.

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