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

readOnlyHint=true already tells the agent this is a safe, non-mutating call, so the safety profile is covered. The description adds useful non-annotation context by naming the underlying GET endpoint and the fields returned, but says nothing about pagination behavior, result ordering, or permissions.

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?

Single tight sentence that front-loads the resource and the returned fields. The trailing raw endpoint string is boilerplate that adds little for an agent but costs only a few tokens.

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 two-parameter read-only list tool with full schema coverage and no output schema, the description covers the essential return content and the schema covers the parameters. The only real gap is that pagination is not mentioned in the description, though the continuation parameter documents it adequately.

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%, including a warning on organization_id that it is not the organizer id and a clear explanation of continuation for pagination. The description adds nothing beyond the schema here, so the baseline 3 applies.

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?

States a specific verb and resource ('List the saved venues of an organization') plus what comes back (address and capacity), which clearly separates it from write siblings like eventbrite_create_venue. It does not, however, explicitly contrast itself with the closest read siblings (eventbrite_list_organizations, eventbrite_get_capacity), so it stops short of full sibling differentiation.

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 contains no when-to-use condition, no prerequisite, and no alternative tool to prefer under other circumstances. An agent must infer from the name alone that this is the way to enumerate an organization's venues.

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