create_webhook

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

With no annotations, the description carries the behavioral disclosure burden. It meaningfully reveals that the response contains a signing secret and instructs the agent to store it securely for signature verification—important stateful behavior beyond the input schema. It does not mention other side effects, but the most critical one is covered.

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?

Two sentences, no fluff, and the primary action is front-loaded. The security note is valuable and earns its place. Perfectly sized for the tool's complexity.

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?

For a simple creation tool with no output schema, the description covers the purpose and the most critical response behavior (the signing secret). It doesn't describe the full response shape or mention the webhook ID, which would be useful for later get/delete operations, but the core invocation context is adequate.

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 does not add any detail about the parameters themselves (url, eventTypes, description); all parameter meaning derives from the schema. No extra guidance is needed, but no value is added either.

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 a specific verb ('Create') and resource ('PDFGate webhook subscription'), making it easy to distinguish from siblings like get_webhook and delete_webhook. The action and object are unambiguous and correctly scoped.

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 such as get_webhook or delete_webhook, nor any mention of prerequisites or setup steps. The usage context is only implied by the verb 'create'.

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