create_webhook

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

With no annotations provided, the description carries the full burden. It states the tool creates a 'user-level webhook' and mentions real-time notifications, but doesn't disclose behavioral traits like whether the webhook is immediately active, what happens on duplicate creation, or permission requirements. The correction about `triggers` vs `eventTriggers` adds useful context.

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 very concise at two sentences, with a clear and helpful warning in the second sentence. It's front-loaded with the core purpose. No extraneous information.

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 an output schema exists (so return values need not be described), 4 parameters, and no nested objects, the description is adequate but minimal. It doesn't elaborate on scoping (what 'user-level' means vs event-type), rate limits, or troubleshooting guidance for webhook setup.

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%, so the baseline is 3. The description adds value by specifying the correct parameter name (`triggers` vs `eventTriggers`) and noting the `active` default is true. This addresses an important nuance not fully captured in the schema's individual parameter descriptions.

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 this tool creates a user-level webhook for real-time event notifications, distinguishing it from sibling tools like list_webhooks, update_webhook, delete_webhook, and the event-type-specific webhook tools.

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 an explicit usage correction (use `triggers`, not `eventTriggers`) and implies this is for user-level webhooks, which differentiates it from event-type webhook tools. However, it doesn't explicitly state when NOT to use this tool or list alternative tools for event-type webhooks.

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