eb_ticket_class

Get one ticket class of an event by id. Use eb_ticket_classes to list them first.

Input Schema

No field projection on this tool: this server has no verified record of which Eventbrite fields matter here, and inventing one would risk dropping a field a caller needs.

A4/5.0
Behavior3/5

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

The readOnlyHint annotation already covers the safety profile, and 'Get' aligns with it, so there is no contradiction. The description adds no further behavioral context such as not-found behavior, auth requirements, or response format, but for a simple read operation the annotation carries most of the burden.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, with the core purpose front-loaded and the usage prerequisite in the second sentence. Every word is purposeful and there is no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a straightforward read-by-id tool with fully documented parameters and a readOnly annotation, the description covers the necessary workflow and purpose. It does not describe the response shape or error cases, but no output schema exists and the return value is largely inferable from 'Get one ticket class.'

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and each parameter is already well explained, especially the view parameter. The tool description adds only 'by id' and the list-first prerequisite, so it does not significantly add meaning beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

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: 'Get one ticket class of an event by id.' It also names the sibling tool eb_ticket_classes, making the singular-vs-list distinction immediately clear.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly instructs the agent to call eb_ticket_classes first in order to list ticket classes, which establishes the correct workflow and points to the relevant alternative. It does not explicitly list when not to use this tool, but the contrast with the list tool is clear enough.

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