create_webhook

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

No annotations are provided, so the description must carry the full burden. It only states 'Create a webhook' with no details on authentication, rate limits, idempotency, or what happens after creation (e.g., return value, activation status).

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?

The description is a single short sentence (5 words). While concise, it lacks structure and does not earn its place by providing useful context beyond the tool name and title.

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?

Given no output schema and no annotations, the description should provide more context about return values, error handling, or side effects. It fails to inform the agent about expected outcomes or limitations.

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 coverage is 100% (all three parameters have descriptions). The description adds no additional meaning beyond the schema, which already explains 'endpoint_url', 'actions', and 'event_id'. At baseline 3, the description is adequate but not enhanced.

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?

The description 'Create a webhook for Eventbrite events' clearly states the action (create) and resource (webhook) and implies the context (Eventbrite events). It distinguishes from siblings like list_webhooks and delete_webhook. However, it could be more specific about the type of webhook (e.g., subscriptions to event notifications).

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?

No guidance is provided on when to use this tool versus alternatives like list_webhooks or delete_webhook. There is no mention of prerequisites (e.g., event_id optionality) or context for choosing this tool.

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