create_webhook

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

Without annotations, the description adds key behavioral context: the response includes a one-time webhook_secret that must be persisted for HMAC validation, and it counts against a cap. However, it omits details like idempotency, duplicate handling, or auth requirements.

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 brief (two sentences), front-loaded with the action, and every sentence adds essential information without redundancy.

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 (3 parameters, no output schema, no annotations), the description is incomplete. It lacks parameter explanations and return value details beyond the secret, which are needed 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?

The schema has 0% coverage with no descriptions, and the description does not explain the purpose or usage of any of the three parameters (webhook_url, subscriber_name, notes), leaving the agent to infer from names and constraints.

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 clearly states 'Create a webhook subscription' with a specific verb ('Create') and resource ('webhook subscription'), and it distinguishes from sibling tools (attach, delete, detach, pause, resume, list) by focusing on creation.

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 notes that the tool 'Counts against the subscription cap,' which implies usage constraints, but lacks explicit when-to-use or when-to-avoid guidance or comparisons with alternatives.

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