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. It discloses that the tool returns a secret for signature verification and instructs to save it, but does not mention authentication needs, rate limits, or consequences of invalid URL. Adequate but not fully transparent.

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 concise: two sentences plus examples. Each sentence adds value, front-loading the purpose. No unnecessary words.

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 output schema exists (not shown), the description need not detail return values. It covers required parameters with examples, mentions the returned secret, and provides event examples. Lacks mention of potential errors or prerequisites, but is sufficiently complete for a creation tool.

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?

With 0% schema description coverage, the description compensates by explaining the purpose of name, url, and events fields, including the special value ['*'] for all events and example event patterns. However, the optional 'description' parameter is not explained.

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 the tool creates a webhook to receive event notifications. It specifies the verb 'create' and resource 'webhook', distinguishing it from sibling tools like get_webhook or list_webhooks.

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 provides clear instructions on required inputs (name, url, events) and examples of events. It strongly implies usage when event notifications are needed, but lacks explicit when-not or alternative guidance, which is acceptable given this is the only webhook creation tool.

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