create-webhook

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the action ('create') without explaining what happens after creation (e.g., whether it returns an ID, how webhooks are triggered, authentication needs, rate limits, or error handling). This leaves critical behavioral traits undocumented for a mutation tool.

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 extremely concise with a single sentence, 'Create a webhook', which is front-loaded and wastes no words. However, this conciseness comes at the cost of under-specification, but per the scoring rules, it earns full marks for brevity and structure.

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 the complexity of a webhook creation tool (a mutation with no annotations, no output schema, and incomplete parameter documentation), the description is severely inadequate. It doesn't cover what the tool returns, how to handle the created webhook, or integration with sibling tools. The lack of behavioral and parameter details makes it incomplete for effective use.

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 50% (only the 'event' parameter has a description listing possible values). The description adds no parameter semantics beyond what's in the schema—it doesn't explain what 'url' is for (e.g., endpoint for notifications) or provide context for the 'event' enum values. With low schema coverage, the description fails to compensate, leaving half the parameters poorly documented.

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' is a tautology that restates the tool name without adding meaningful context. It specifies the verb ('create') and resource ('webhook'), but lacks details about what a webhook is for in this system or what it does. It doesn't distinguish from siblings like 'delete-webhook' or 'list-webhooks' beyond the obvious action difference.

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. It doesn't mention prerequisites (e.g., needing a valid URL or event type), when it's appropriate (e.g., for real-time notifications), or when not to use it (e.g., for one-time checks). There's no reference to sibling tools like 'list-webhooks' for viewing existing webhooks.

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