eb_org_ticket_groups

Read-only

List ticket groups for an Eventbrite organization to see how ticket classes are bundled across events. Use the org ID and optional pagination to retrieve compact or full results.

Instructions

List an organization's ticket groups (ticket classes bundled across events).

Input Schema

NameRequiredDescriptionDefault
viewNoResponse shape: "compact" (default) drops fields the response already carries elsewhere; "full" returns every field this server understands. compact strips image/avatar URLs from the response; "full" returns Eventbrite's payload untouched. 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.
org_idYesOrganization id (from eb_my_organizations)
continuationNoPagination continuation token from a previous response

B3.3/5.0
Behavior3/5

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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds the org-scoping constraint and a definition of ticket groups, but says nothing about pagination behavior despite the continuation param, or about what a returned group contains.

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?

A single tight sentence with the resource and its definition front-loaded and zero filler. Nothing to trim.

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

Completeness3/5

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

With full schema coverage and annotations handling the safety profile, the definition is minimally adequate. For a list tool with no output schema, it still doesn't hint at the shape or count of ticket groups returned, nor how continuation-driven paging works, leaving some gaps.

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%, so org_id, view, and continuation are already documented in the schema; the description adds no syntax, format, or default details beyond what is there. Baseline 3 applies when the schema carries the parameter burden.

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

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (List) and resource (ticket groups), and the parenthetical 'ticket classes bundled across events' defines the resource so an agent isn't guessing what a ticket group is. It does not explicitly contrast with near-siblings like eb_ticket_classes or eb_org_events, so it stops short of the 5 bar.

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

Usage Guidelines2/5

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

The description only says what the tool does; it gives no guidance on when to use it versus eb_ticket_classes, eb_org_events, or eb_ticket_class, and no prerequisites beyond the schema-embedded 'from eb_my_organizations' hint.

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