eb_order

Read-only

Fetch a specific Eventbrite order by its numeric ID to access the buyer-side record behind a ticket. Use order IDs from order list results to retrieve full order details.

Instructions

Get a single order by id (the buyer-side record behind a ticket). Order ids appear in eb_my_orders / eb_event_orders results.

Input Schema

TableJSON 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.
expandNoComma-separated expansions, e.g. 'attendees,event'
order_idYesNumeric order id

A4.2/5.0
Behavior3/5

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

The annotations already declare readOnlyHint=true, and the description's 'Get a single order' is consistent with that. The description adds a small bit of domain context by identifying the order as the buyer-side record behind a ticket, but it does not disclose additional behavioral traits such as response size, expansion effects, or error behavior. Given the annotation coverage, a 3 is appropriate.

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?

The description is two short sentences with no redundancy. It front-loads the core action ('Get a single order by id') and follows with essential provenance for the id parameter. Every sentence earns its place.

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 simple get-by-id tool with a fully described input schema and a read-only annotation, the description covers the essential context: the resource, the required parameter's source, and the relationship to list endpoints. The lack of an output schema is partially mitigated by the view parameter's detailed description of compact vs full response shapes, so nothing critical is missing.

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

Parameters4/5

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

Schema description coverage is 100%, so baseline is 3. The description adds value by telling the caller where order ids come from ('Order ids appear in eb_my_orders / eb_event_orders results'), which is operationally useful for supplying the required order_id parameter. This goes slightly beyond what the schema provides.

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 states a specific verb and resource: 'Get a single order by id'. It also contextualizes the resource as 'the buyer-side record behind a ticket', and clarifies that order ids come from eb_my_orders / eb_event_orders results, which differentiates this from the list-oriented sibling tools.

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?

The description clearly implies when to use the tool: when you already have an order id, particularly one obtained from the listed order-list endpoints. It does not explicitly say when not to use it or name alternatives, but the single-vs-list distinction among siblings is strongly implied.

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