eb_org_discounts

Read-only

List an organization's discount and access codes, including usage limits. Provide org_id to retrieve current codes and pagination.

Instructions

List an organization's discount and access codes, including their usage limits.

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.
org_idYesOrganization id (from eb_my_organizations)
continuationNoPagination continuation token from a previous response

A3.8/5.0
Behavior3/5

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

Annotations declare readOnlyHint=true and the description's 'List' matches that read-only behavior with no contradiction. The description adds minimal behavioral context beyond the annotation: it only promises that usage limits are included, and says nothing about pagination behavior or response shape.

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?

One tightly worded sentence with the verb and resource front-loaded, and no redundant or filler content. The clause 'including their usage limits' is the only useful extra and 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 read-only listing tool, the description plus fully documented schema parameters and the readOnlyHint cover what is needed to invoke it correctly. The only minor gap is that the return format and pagination behavior are not described, but these are already implied by the schema and the absence of an output schema lowers the burden.

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?

The input schema already covers all three parameters with meaningful descriptions, including org_id provenance and continuation-token semantics, so the description does not need to add parameter detail. The description contributes nothing specific to parameter meaning beyond framing the response around discount/access codes.

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?

Description states a precise action ('List') and a distinctive resource ('an organization's discount and access codes'), and adds the useful detail that usage limits are included. Among the sibling org_* tools, none target discounts/access codes, so the definition distinguishes itself without opening the schema.

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

Usage Guidelines3/5

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

The org-scoped phrasing makes it evident this is for listing discount codes for a specific organization, and no sibling tool overlaps, so usage context is implied. However, the description does not explicitly state when to choose this tool, what prerequisites exist (other than the org_id hint in the schema), or how it relates to other org listing tools.

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